Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business, Basis of Presentation and Summary of Significant Accounting Policies | 1. Description of Business, Basis of Presentation and Summary of Significant Accounting Policies Description of Business International Stem Cell Corporation (the “Company”) was organized in Delaware in June 2005 and is headquartered in San Diego, California. The Company is primarily a research and development company for the therapeutic market, which has focused on advancing potential clinical applications of human parthenogenetic stem cells (“hpSCs”) for the treatment of various diseases of the central nervous system and liver. The Company has the following wholly owned subsidiaries: • Lifeline Cell Technology, LLC (“LCT”) – for the biomedical market, develops, manufactures and commercializes primary human cell research products, including over 200 human cell culture products such as frozen human “primary” cells and the reagents (called “media”) needed to grow, maintain and differentiate the cells; • Lifeline Skin Care, Inc. (“LSC”) – for the anti-aging market, develops, manufactures and markets a category of anti-aging skin care products based on the Company’s proprietary parthenogenetic stem cell technology and small molecule technology; • Cyto Therapeutics Pty. Ltd. (“Cyto Therapeutics”) – performs research and development (“R&D”) for the therapeutic market and is currently conducting clinical trials in Australia for the use of ISC-hpNSC® in the treatment of Parkinson’s disease. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial statements. Certain information and notes normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations. The unaudited interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s condensed consolidated financial statements. The operating results For the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2022 included in the Company’s annual report on Form 10-K filed with the SEC on March 30, 2023 . Liquidity and Going Concern The Company had an accumulated deficit of approximately $ 110.4 million as of March 31, 2023 and has incurred net losses and negative operating cash flows annually, since inception. The Company has generated no revenue from its therapeutic product candidates. Unless the Company obtains additional financing, the Company does not have sufficient cash on hand to sustain operations for at least twelve months from the issuance date of these condensed consolidated financial statements. There can be no assurance that the Company will be successful in maintaining normal operating cash flow or obtaining additional funding. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. For the foreseeable future, the Company’s ability to continue its operations is dependent upon its ability to obtain additional financing. The accompanying condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern. The Company continues to evaluate various financing sources and options to raise working capital to help fund current research and development programs and operations. The Company plans to obtain significant additional funding from sources, including through debt and equity financing, license arrangements, grants and/or collaborative research arrangements to sustain its operations and develop products. The timing and degree of any future capital requirements will depend on several factors, including: • the accuracy of the assumptions underlying the estimates for capital needs; • the extent that revenues from sales of LSC and LCT products cover the related costs and provide capital; • scientific progress in research and development programs; • the magnitude and scope of the Company’s research and development programs and its ability to establish, enforce and maintain strategic arrangements for research, development, clinical testing, manufacturing and marketing; • the progress with preclinical development and clinical trials; • the time and costs involved in obtaining regulatory approvals; • the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; • the number and type of product candidates that the Company decides to pursue; and • demand from the Company’s largest original equipment manufacturer customers. Additional debt financing may be expensive and require the Company to pledge all or a substantial portion of its assets. If additional funds are obtained through arrangements with collaborative partners, these arrangements may require the Company to relinquish the rights to some of its technologies, product candidates, or products that the Company would otherwise seek to develop and commercialize on its own. Furthermore, if sufficient capital is not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its product initiatives. The Company’s failure to raise capital or enter into related arrangements when needed would have a negative impact on its financial condition. Principles of Consolidation and Foreign Currency Transactions The condensed consolidated financial statements include the accounts of International Stem Cell Corporation and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The functional currency of the Company and its wholly owned subsidiaries is the U.S. dollar. Monetary assets and liabilities that are not denominated in the functional currency are remeasured each reporting period into U.S. dollars at foreign currency exchange rates in effect at the respective balance sheet date. Non-monetary assets and liabilities and equity are remeasured at the historical exchange rates. Revenue and expenses are remeasured at the average rate in effect on the date of the transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in general and administrative expense in the accompanying condensed consolidated statements of operations and were not material for the periods presented. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Significant estimates include patent life (remaining legal life versus remaining useful life), inventory carrying values, and the fair value of stock option grants using the Black-Scholes option valuation model. By their nature, estimates are subject to an inherent degree of uncertainty and actual results could differ from these estimates. Segments The Company’s chief operating decision-maker reviews financial information presented on a consolidated basis, accompanied by disaggregated information for each reportable company’s statement of operations. The Company operates the business on the basis of three reporting segments: ISCO – therapeutic market; LCT – biomedical market, and; LSC – anti-aging market. Inventory, net Inventory is accounted for using the average cost and first-in, first-out (“FIFO”) methods for LCT cell culture media and reagents, average cost and specific identification methods for LSC products, and specific identification method for other LCT products. Inventory balances are stated at the lower of cost or net realizable value. Laboratory supplies used in the research and development process are expensed as consumed. LCT’s inventory has a long product life cycle, does not have a shelf life when frozen, and future demand is uncertain. At each reporting period, the Company estimates its reserve allowance for excess and obsolete inventory using historical sales data and inventory turnover rates. The establishment of a reserve for excess and obsolete inventory establishes a new cost basis in inventory. If the Company is able to sell previously reserved inventory, the related reserves and inventory balances would be reduced in the period of sale. The value of the inventory that is not expected to be sold within twelve months of the current reporting period is classified as non-current inventory on the accompanying condensed consolidated balance sheets. Accounts Receivable, net Trade accounts receivable are recorded at the invoice value, net of discounts, and are not interest bearing. Accounts receivable primarily consist of trade accounts receivable from the sales of LCT’s products as well as LSC trade receivable amounts related to spa and distributor sales. The Company considers receivables past due based on the contractual payment terms. The Company measures expected credit losses for financial instruments at each reporting date based on historical experience, current conditions and reasonable forecasts. The allowance for doubtful accounts represents the Company’s estimate of expected credit losses relating to these factors. Amounts are written off against the allowances for doubtful accounts when the Company determines that a customer account is uncollectible. As of March 31, 2023 and December 31, 2022 , the Company’s allowance for doubtful accounts was immaterial. Intangible Assets Intangible assets consist of acquired patent licenses and capitalized legal fees related to the acquisition, filing, maintenance, and defense of patents and trademarks. Amortization begins once the patent is issued by the appropriate authoritative bodies. In the period in which a patent application is rejected or efforts to pursue the patent are abandoned, all the related accumulated capitalized costs are expensed. Patents and other intangible assets are amortized on a straight-line basis over the useful life of the underlying patent, which is generally 15 years. All amortization expense related to intangible assets is included in general and administrative expenses in the accompanying condensed consolidated statements of operations. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use assets, operating lease obligations, current, and operating lease obligations, net of current portion, on the Company’s consolidated balance sheets. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of future minimum lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses a discount rate based on its estimated incremental borrowing rate to determine the right-of-use asset and operating lease liabilities to be recognized. The Company determines its incremental borrowing rate based on the terms and lease payments of its operating leases and what it would normally pay to borrow, on a collateralized basis, over similar terms for an amount equal to the lease payments. Operating lease expense is recognized on a straight-line basis over the lease term. In addition, the Company does not separate lease components from non-lease components. Long-Lived Asset Impairment The Company reviews long-lived assets for impairment when events or changes in circumstances (“triggering event”) indicate that the carrying value of an asset or group of assets may not be recovered. If a triggering event is determined to have occurred, the carrying value of an asset or group of assets is compared to the future undiscounted cash flows expected to be generated by the asset or group of assets. If the carrying value exceeds the undiscounted cash flows of the asset or group of assets, then an impairment exists, which is measured as the excess of fair value over the asset or asset group’s carrying value. Fair value is generally determined using the asset’s expected future discounted cash flows or market value, if readily determinable. Revenue Recognition The Company's revenue consists primarily of sales of products from its two revenue-generating operating segments, the biomedical market (LCT) and anti-aging market (LSC). The anti-aging market sells products solely through the ecommerce channel. The biomedical market sells primary human cell research products with two product categories, cells and media, which are sold both domestically and internationally. The biomedical market also offers performance of quality control (QC) testing services. No revenue from services was earned during the three months ended March 31, 2023 and 2022 . The following table presents the Company's revenue disaggregated by segment, product group, and geography (in thousands, except percentages): Biomedical market: Three Months Ended March 31, 2023 Total % of Total Domestic International Revenues Revenues Biomedical products Cells $ 530 $ 192 $ 722 39 % Media 984 162 1,146 61 % Total $ 1,514 $ 354 $ 1,868 100 % Three Months Ended March 31, 2022 Total % of Total Domestic International Revenues Revenues Biomedical products Cells $ 337 $ 109 $ 446 25 % Media 1,213 112 1,325 75 % Total $ 1,550 $ 221 $ 1,771 100 % Anti-aging market: Three Months Ended March 31, 2023 2022 Skin care sales channels $ 218 $ 249 Contract terms for the unit price, quantity, shipping and payment are governed by sales agreements, invoices or online order forms, which the Company considers to be a customer's contract. The unit price is considered the observable stand-alone selling price for the performance obligation(s) within the arrangements. Any promotional or volume sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. The Company recognizes revenue when its customer obtains control of the promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. Product sales generally consist of a single performance obligation that the Company satisfies at a point in time (i.e., upon delivery of the product). For LSC products, ecommerce sales are primarily paid through credit card charges. The anti-aging and biomedical products' standard payment terms for its customers are generally 30 days after the Company satisfies the performance obligation(s). The Company elects to account for shipping and handling costs, recognized as cost of sales, as activities to fulfill the promise to transfer the goods to a customer. As a result, no consideration is allocated to shipping and handling costs. Rather, the Company accrues the cost of shipping and handling upon shipment of the product, and all contract revenue (i.e., the transaction price) is recognized at the same time. Variable Consideration The Company records revenue from customers in an amount that reflects the consideration it expects to be entitled to after transferring control of those goods or services to a customer. From time to time, the Company offers sales promotions on its products such as discounts and free product offers. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur and is updated at the end of each reporting period as additional information becomes available. Contract Balances The Company records a receivable when it has an unconditional right to receive consideration after a performance obligation is satisfied. As of March 31, 2023 and December 31, 2022, accounts receivable, net, totaled $ 688 thousand and $ 747 thousand, respectively. During the three months ended March 31, 2023 and 2022 , the Company did no t incur material write-offs of its accounts receivable. Practical Expedients The Company has elected the practical expedient to not determine whether contracts with customers contain significant financing components. The Company pays commissions on certain sales for its biomedical and anti-aging product markets once the customer payment has been received, which are accrued at the time of sale. The Company generally expenses sales commissions when incurred because the amortization period would be one year or less. These costs are recorded within selling and marketing expenses. In addition, the Company has elected to exclude sales taxes consideration from the determined transaction price. Cost of Sales Cost of sales consists primarily of salaries and benefits associated with employee efforts expended directly on the production of the Company’s products as well as related direct materials, shipping costs, general laboratory supplies and an allocation of overhead. Research and Development Costs Research and development costs, which are expensed as incurred, primarily consist of salaries and benefits associated with research and development personnel, overhead and occupancy costs, contract services costs, and amortization of license costs for technology used in research and development with alternative future uses, offset by the research and development tax credit provided by the Australian Taxation Office for qualified expenditures. Australian Research and Development Tax Credit The Company’s wholly owned subsidiary, Cyto Therapeutics, conducts various research and development activities on the Company’s product candidates in Australia. Under Australian tax law, the Australian Taxation Office provides for a refundable tax credit in the form of a cash refund equal to 43.5 % of qualified research and development expenditures, not to exceed established thresholds. The Australian R&D tax incentive program is a self-assessment process and the Australian Government has the right to review the Company’s qualifying programs and related expenditures for a period of four years. If such a review were to occur and, as a result of the review and failure of a related appeal, the qualified program and related expenditures were disqualified, the respective research and development refunds could be recalled with penalties and interest. The refundable tax credit does not depend on the Company’s generation of future taxable income or ongoing tax status or position. Accordingly, the credit is not considered an element of income tax accounting under ASC 740 “Income Taxes”. The Company uses the grant accounting model by analogy to International Accounting Standards (IAS) 20 to account for the refundable tax credit from the Australian government. The Company recognizes the research and development tax credit as a reduction to research and development expense when there is reasonable assurance that the tax credit will be received, the relevant expenses have been incurred, and the amount can be reliably measured. For the three months ended March 31, 2023 and 2022 , no tax credits were provided. Stock-Based Compensation The cost of a stock-based award is measured at the grant date based on the estimated fair value of the award. Stock-based compensation is recognized as expense on a straight-line basis, net of forfeitures, which are recognized as incurred, over the requisite service period of the award. The fair value of stock options is estimated using the Black-Scholes option valuation model, which requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. Net Loss Per Share Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Potentially dilutive common stock equivalents are comprised of stock options and convertible preferred stock. For the three months ended March 31, 2023 and 2022, there was no difference in the number of shares used to calculate basic and diluted shares outstanding. For the three months ended March 31, 2023 and 2022, the following common stock options and convertible preferred stock were not included in the diluted net loss per share calculation because the effect would be anti-dilutive: March 31, March 31, 2023 2022 Options outstanding 6,858,492 5,372,535 Redeemable convertible preferred stock 2,457,143 2,457,143 Non-redeemable convertible preferred stock 3,619,379 3,619,379 Total 12,935,014 11,449,057 Customer Concentrations For the three months ended March 31, 2023 and 2022 , one customer accounted for approximately 47 % and 45 % of consolidated revenues, respectively. As of March 31, 2023 and December 31, 2022, the customer accounted for approximately 47 % and 73 % , respectively, of accounts receivable, net. No other single customer accounted for more than 10% of revenues for the periods then ended for any segment. Recently Issued Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded features that could be recognized separately from the host contract. Consequently, more convertible debt instruments will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. ASU 2020-06 also requires use of the if-converted method in the diluted earnings per share calculation for convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years for smaller reporting companies, with early adoption permitted. The new standard will be effective for the Company on January 1, 2024 or at such earlier time where it is no longer a smaller reporting company. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments— Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The ASU introduced a new credit loss methodology, the Current Expected Credit Losses (“CECL”) methodology, which requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL methodology utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to maturity debt securities, trade receivables and other receivables measured at amortized cost at the time the financial asset is originated or acquired. Subsequent to the issuance of ASU 2016-13, the FASB issued several additional ASUs to clarify implementation guidance, provide narrow-scope improvements and provide additional disclosure guidance. In November 2019, the FASB issued an amendment making this ASU effective for fiscal years beginning after December 15, 2022 for smaller reporting companies. The Company adopted ASC 2016-13 on January 1, 2023 . The adoption of this standard did no t have a material impact on the Company's condensed consolidated financial statements. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force) (“ASU 2021-04”), which clarifies and reduces the diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. ASU 2021-04 is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2021-04 on January 1, 2022 . The adoption of this standard did no t have a material impact on the Company's condensed consolidated financial statements. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosure by Business Entities about Government Assistance (“ASU 2021-10”), which improves the transparency of government assistance received by certain business entities by requiring the disclosure of (1) the types of government assistance received; (2) the accounting for such assistance, and (3) the effect of the assistance on the business entity’s financial statements. ASU 2021-10 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. The Company adopted ASU 2021-10 on January 1, 2022 . The adoption of this standard did no t have a material impact on the Company’s condensed consolidated financial statements. |

Related Party Transactions [Abstract] | |
Related Party Transactions | 7. Related Party Transactions Related party lease arrangements On October 26, 2021, the Company and S Real Estate Holdings, LLC, a related party, entered jointly into a lease agreement with Rehco Holdings, LLC (the “Lease”), for the purpose of establishing a new corporate headquarters, including corporate, R&D, and manufacturing operations. The lease commenced on November 1, 2021 and expires on December 31, 2026 with no options to extend or renew. The lease was personally guaranteed by Dr. Russell Kern, the Company’s Executive Vice President and Chief Scientific Officer. On December 15, 2021, the Company and S Real Estate Holdings LLC entered into a co-tenant agreement, whereby the Company and S Real Estate Holdings LLC agreed to allocate portions of the base rent and variable charges, including insurance, maintenance costs, taxes and operating expenses, between the parties. During the term of the Lease, the Company will be liable for 40 % of all costs incurred in connection with the lease, while S Real Estate Holdings LLC will be liable for the remaining 60 %. Related party note payable As of December 31, 2021, the Company had an unsecured, non-convertible promissory note, with a principal outstanding amount of $ 2.7 million (the “Note”) and accrued interest of approximately $ 300 thousand with Dr. Andrey Semechkin, the Company’s Chief Executive Office and Co-Chairman of the Board of Directors. The outstanding principal amount under the Note accrued interest at a rate of 4.5 % per annum. The outstanding principal and accrued interest on the Note was due and payable on January 15, 2022 and could be pre-paid without penalty at any time. On January 13, 2022, to obtain funding for working capital purposes, the Company issued an unsecured, non-convertible promissory note in the principal amount of $ 2.9 million (the "Modified Note”) to Dr. Semechkin. In exchange, Dr. Semechkin surrendered the Note and provided an additional $ 250 thousand to the Company. The Modified Note, including outstanding amounts of principal and accrued interest, was due and payable on March 15, 2022 . On March 1, 2022, the Company and Dr. Andrey Semechkin restructured the Modified Note and agreed to extend the maturity date for an additional six-month period to September 15, 2022 . On September 15, 2022, the Company and Dr. Andrey Semechkin extended the Modified Note for an additional six-month period to March 15, 2023 . No other terms of the Modified Note were modified. On September 15, 2022, the Noteholder surrendered the March 2022 Note, and the Company issued a new promissory note (“September 2022 Note”), which featured all the same terms as the previously outstanding note, with the exception of an extension of the maturity date from September 15, 2022 to March 15, 2023 . The September 2022 Note has a principal balance of $ 2.9 million, an interest rate of 4.5 %, and features optional prepayment terms. There were no debt issuance fees associated with this issuance. On March 14, 2023, the Noteholder surrendered the September 2022 Note, and the Company issued a new promissory note (“March 2023 Note”), which featured all the same terms as the previously outstanding note, with the exception of an extension of the maturity date from March 15, 2023 to September 15, 2023 . The March 2023 Note has a principal balance of $ 2.9 million, an interest rate of 4.5 %, and features optional prepayment terms. There were no debt issuance fees associated with this issuance. The amendments qualify as a troubled debt restructuring which did not result in a gain as the carrying amount of the debt was less than the total future cash payments of the restructured debt. |

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business | Description of Business International Stem Cell Corporation (the “Company”) was organized in Delaware in June 2005 and is headquartered in San Diego, California. The Company is primarily a research and development company for the therapeutic market, which has focused on advancing potential clinical applications of human parthenogenetic stem cells (“hpSCs”) for the treatment of various diseases of the central nervous system and liver. The Company has the following wholly owned subsidiaries: • Lifeline Cell Technology, LLC (“LCT”) – for the biomedical market, develops, manufactures and commercializes primary human cell research products, including over 200 human cell culture products such as frozen human “primary” cells and the reagents (called “media”) needed to grow, maintain and differentiate the cells; • Lifeline Skin Care, Inc. (“LSC”) – for the anti-aging market, develops, manufactures and markets a category of anti-aging skin care products based on the Company’s proprietary parthenogenetic stem cell technology and small molecule technology; • Cyto Therapeutics Pty. Ltd. (“Cyto Therapeutics”) – performs research and development (“R&D”) for the therapeutic market and is currently conducting clinical trials in Australia for the use of ISC-hpNSC® in the treatment of Parkinson’s disease. |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial statements. Certain information and notes normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations. The unaudited interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s condensed consolidated financial statements. The operating results For the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2022 included in the Company’s annual report on Form 10-K filed with the SEC on March 30, 2023 . |
Liquidity and Going Concern | Liquidity and Going Concern The Company had an accumulated deficit of approximately $ 110.4 million as of March 31, 2023 and has incurred net losses and negative operating cash flows annually, since inception. The Company has generated no revenue from its therapeutic product candidates. Unless the Company obtains additional financing, the Company does not have sufficient cash on hand to sustain operations for at least twelve months from the issuance date of these condensed consolidated financial statements. There can be no assurance that the Company will be successful in maintaining normal operating cash flow or obtaining additional funding. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. For the foreseeable future, the Company’s ability to continue its operations is dependent upon its ability to obtain additional financing. The accompanying condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern. The Company continues to evaluate various financing sources and options to raise working capital to help fund current research and development programs and operations. The Company plans to obtain significant additional funding from sources, including through debt and equity financing, license arrangements, grants and/or collaborative research arrangements to sustain its operations and develop products. The timing and degree of any future capital requirements will depend on several factors, including: • the accuracy of the assumptions underlying the estimates for capital needs; • the extent that revenues from sales of LSC and LCT products cover the related costs and provide capital; • scientific progress in research and development programs; • the magnitude and scope of the Company’s research and development programs and its ability to establish, enforce and maintain strategic arrangements for research, development, clinical testing, manufacturing and marketing; • the progress with preclinical development and clinical trials; • the time and costs involved in obtaining regulatory approvals; • the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; • the number and type of product candidates that the Company decides to pursue; and • demand from the Company’s largest original equipment manufacturer customers. Additional debt financing may be expensive and require the Company to pledge all or a substantial portion of its assets. If additional funds are obtained through arrangements with collaborative partners, these arrangements may require the Company to relinquish the rights to some of its technologies, product candidates, or products that the Company would otherwise seek to develop and commercialize on its own. Furthermore, if sufficient capital is not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its product initiatives. The Company’s failure to raise capital or enter into related arrangements when needed would have a negative impact on its financial condition. |
Principles of Consolidation and Foreign Currency Transactions | Principles of Consolidation and Foreign Currency Transactions The condensed consolidated financial statements include the accounts of International Stem Cell Corporation and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The functional currency of the Company and its wholly owned subsidiaries is the U.S. dollar. Monetary assets and liabilities that are not denominated in the functional currency are remeasured each reporting period into U.S. dollars at foreign currency exchange rates in effect at the respective balance sheet date. Non-monetary assets and liabilities and equity are remeasured at the historical exchange rates. Revenue and expenses are remeasured at the average rate in effect on the date of the transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in general and administrative expense in the accompanying condensed consolidated statements of operations and were not material for the periods presented. |
Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Significant estimates include patent life (remaining legal life versus remaining useful life), inventory carrying values, and the fair value of stock option grants using the Black-Scholes option valuation model. By their nature, estimates are subject to an inherent degree of uncertainty and actual results could differ from these estimates. |
Segments | Segments The Company’s chief operating decision-maker reviews financial information presented on a consolidated basis, accompanied by disaggregated information for each reportable company’s statement of operations. The Company operates the business on the basis of three reporting segments: ISCO – therapeutic market; LCT – biomedical market, and; LSC – anti-aging market. |
Inventory, net | Inventory, net Inventory is accounted for using the average cost and first-in, first-out (“FIFO”) methods for LCT cell culture media and reagents, average cost and specific identification methods for LSC products, and specific identification method for other LCT products. Inventory balances are stated at the lower of cost or net realizable value. Laboratory supplies used in the research and development process are expensed as consumed. LCT’s inventory has a long product life cycle, does not have a shelf life when frozen, and future demand is uncertain. At each reporting period, the Company estimates its reserve allowance for excess and obsolete inventory using historical sales data and inventory turnover rates. The establishment of a reserve for excess and obsolete inventory establishes a new cost basis in inventory. If the Company is able to sell previously reserved inventory, the related reserves and inventory balances would be reduced in the period of sale. The value of the inventory that is not expected to be sold within twelve months of the current reporting period is classified as non-current inventory on the accompanying condensed consolidated balance sheets. |
Accounts Receivable, net | Accounts Receivable, net Trade accounts receivable are recorded at the invoice value, net of discounts, and are not interest bearing. Accounts receivable primarily consist of trade accounts receivable from the sales of LCT’s products as well as LSC trade receivable amounts related to spa and distributor sales. The Company considers receivables past due based on the contractual payment terms. The Company measures expected credit losses for financial instruments at each reporting date based on historical experience, current conditions and reasonable forecasts. The allowance for doubtful accounts represents the Company’s estimate of expected credit losses relating to these factors. Amounts are written off against the allowances for doubtful accounts when the Company determines that a customer account is uncollectible. As of March 31, 2023 and December 31, 2022 , the Company’s allowance for doubtful accounts was immaterial. |
Intangible Assets | Intangible Assets Intangible assets consist of acquired patent licenses and capitalized legal fees related to the acquisition, filing, maintenance, and defense of patents and trademarks. Amortization begins once the patent is issued by the appropriate authoritative bodies. In the period in which a patent application is rejected or efforts to pursue the patent are abandoned, all the related accumulated capitalized costs are expensed. Patents and other intangible assets are amortized on a straight-line basis over the useful life of the underlying patent, which is generally 15 years. All amortization expense related to intangible assets is included in general and administrative expenses in the accompanying condensed consolidated statements of operations. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use assets, operating lease obligations, current, and operating lease obligations, net of current portion, on the Company’s consolidated balance sheets. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of future minimum lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses a discount rate based on its estimated incremental borrowing rate to determine the right-of-use asset and operating lease liabilities to be recognized. The Company determines its incremental borrowing rate based on the terms and lease payments of its operating leases and what it would normally pay to borrow, on a collateralized basis, over similar terms for an amount equal to the lease payments. Operating lease expense is recognized on a straight-line basis over the lease term. In addition, the Company does not separate lease components from non-lease components. |

The Company determines its incremental borrowing rate based on the terms and lease payments of its operating leases and what it would normally pay to borrow, on a collateralized basis, over similar terms for an amount equal to the lease payments. Operating lease expense is recognized on a straight-line basis over the lease term. In addition, the Company does not separate lease components from non-lease components. |
Long-Lived Asset Impairment | Long-Lived Asset Impairment The Company reviews long-lived assets for impairment when events or changes in circumstances (“triggering event”) indicate that the carrying value of an asset or group of assets may not be recovered. If a triggering event is determined to have occurred, the carrying value of an asset or group of assets is compared to the future undiscounted cash flows expected to be generated by the asset or group of assets. If the carrying value exceeds the undiscounted cash flows of the asset or group of assets, then an impairment exists, which is measured as the excess of fair value over the asset or asset group’s carrying value. Fair value is generally determined using the asset’s expected future discounted cash flows or market value, if readily determinable. |
Revenue Recognition | Revenue Recognition The Company's revenue consists primarily of sales of products from its two revenue-generating operating segments, the biomedical market (LCT) and anti-aging market (LSC). The anti-aging market sells products solely through the ecommerce channel. The biomedical market sells primary human cell research products with two product categories, cells and media, which are sold both domestically and internationally. The biomedical market also offers performance of quality control (QC) testing services. No revenue from services was earned during the three months ended March 31, 2023 and 2022 . The following table presents the Company's revenue disaggregated by segment, product group, and geography (in thousands, except percentages): Biomedical market: Three Months Ended March 31, 2023 Total % of Total Domestic International Revenues Revenues Biomedical products Cells $ 530 $ 192 $ 722 39 % Media 984 162 1,146 61 % Total $ 1,514 $ 354 $ 1,868 100 % Three Months Ended March 31, 2022 Total % of Total Domestic International Revenues Revenues Biomedical products Cells $ 337 $ 109 $ 446 25 % Media 1,213 112 1,325 75 % Total $ 1,550 $ 221 $ 1,771 100 % Anti-aging market: Three Months Ended March 31, 2023 2022 Skin care sales channels $ 218 $ 249 Contract terms for the unit price, quantity, shipping and payment are governed by sales agreements, invoices or online order forms, which the Company considers to be a customer's contract. The unit price is considered the observable stand-alone selling price for the performance obligation(s) within the arrangements. Any promotional or volume sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. The Company recognizes revenue when its customer obtains control of the promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. Product sales generally consist of a single performance obligation that the Company satisfies at a point in time (i.e., upon delivery of the product). For LSC products, ecommerce sales are primarily paid through credit card charges. The anti-aging and biomedical products' standard payment terms for its customers are generally 30 days after the Company satisfies the performance obligation(s). The Company elects to account for shipping and handling costs, recognized as cost of sales, as activities to fulfill the promise to transfer the goods to a customer. As a result, no consideration is allocated to shipping and handling costs. Rather, the Company accrues the cost of shipping and handling upon shipment of the product, and all contract revenue (i.e., the transaction price) is recognized at the same time. Variable Consideration The Company records revenue from customers in an amount that reflects the consideration it expects to be entitled to after transferring control of those goods or services to a customer. From time to time, the Company offers sales promotions on its products such as discounts and free product offers. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur and is updated at the end of each reporting period as additional information becomes available. Contract Balances The Company records a receivable when it has an unconditional right to receive consideration after a performance obligation is satisfied. As of March 31, 2023 and December 31, 2022, accounts receivable, net, totaled $ 688 thousand and $ 747 thousand, respectively. During the three months ended March 31, 2023 and 2022 , the Company did no t incur material write-offs of its accounts receivable. Practical Expedients The Company has elected the practical expedient to not determine whether contracts with customers contain significant financing components. The Company pays commissions on certain sales for its biomedical and anti-aging product markets once the customer payment has been received, which are accrued at the time of sale. The Company generally expenses sales commissions when incurred because the amortization period would be one year or less. These costs are recorded within selling and marketing expenses. In addition, the Company has elected to exclude sales taxes consideration from the determined transaction price. |
Cost of Sales | Cost of Sales Cost of sales consists primarily of salaries and benefits associated with employee efforts expended directly on the production of the Company’s products as well as related direct materials, shipping costs, general laboratory supplies and an allocation of overhead. |
Research and Development Costs | Research and Development Costs Research and development costs, which are expensed as incurred, primarily consist of salaries and benefits associated with research and development personnel, overhead and occupancy costs, contract services costs, and amortization of license costs for technology used in research and development with alternative future uses, offset by the research and development tax credit provided by the Australian Taxation Office for qualified expenditures. Australian Research and Development Tax Credit The Company’s wholly owned subsidiary, Cyto Therapeutics, conducts various research and development activities on the Company’s product candidates in Australia. Under Australian tax law, the Australian Taxation Office provides for a refundable tax credit in the form of a cash refund equal to 43.5 % of qualified research and development expenditures, not to exceed established thresholds. The Australian R&D tax incentive program is a self-assessment process and the Australian Government has the right to review the Company’s qualifying programs and related expenditures for a period of four years. If such a review were to occur and, as a result of the review and failure of a related appeal, the qualified program and related expenditures were disqualified, the respective research and development refunds could be recalled with penalties and interest. The refundable tax credit does not depend on the Company’s generation of future taxable income or ongoing tax status or position. Accordingly, the credit is not considered an element of income tax accounting under ASC 740 “Income Taxes”. The Company uses the grant accounting model by analogy to International Accounting Standards (IAS) 20 to account for the refundable tax credit from the Australian government. The Company recognizes the research and development tax credit as a reduction to research and development expense when there is reasonable assurance that the tax credit will be received, the relevant expenses have been incurred, and the amount can be reliably measured. For the three months ended March 31, 2023 and 2022 , no tax credits were provided. |
Stock-Based Compensation | Stock-Based Compensation The cost of a stock-based award is measured at the grant date based on the estimated fair value of the award. Stock-based compensation is recognized as expense on a straight-line basis, net of forfeitures, which are recognized as incurred, over the requisite service period of the award. The fair value of stock options is estimated using the Black-Scholes option valuation model, which requires the input of subjective assumptions, including price volatility of the underlying stock, risk-free interest rate, dividend yield, and expected life of the option. |
Net Loss Per Share | Net Loss Per Share Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Potentially dilutive common stock equivalents are comprised of stock options and convertible preferred stock. For the three months ended March 31, 2023 and 2022, there was no difference in the number of shares used to calculate basic and diluted shares outstanding. For the three months ended March 31, 2023 and 2022, the following common stock options and convertible preferred stock were not included in the diluted net loss per share calculation because the effect would be anti-dilutive: March 31, March 31, 2023 2022 Options outstanding 6,858,492 5,372,535 Redeemable convertible preferred stock 2,457,143 2,457,143 Non-redeemable convertible preferred stock 3,619,379 3,619,379 Total 12,935,014 11,449,057 |
Customer Concentrations | Customer Concentrations For the three months ended March 31, 2023 and 2022 , one customer accounted for approximately 47 % and 45 % of consolidated revenues, respectively. As of March 31, 2023 and December 31, 2022, the customer accounted for approximately 47 % and 73 % , respectively, of accounts receivable, net. No other single customer accounted for more than 10% of revenues for the periods then ended for any segment. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded features that could be recognized separately from the host contract. Consequently, more convertible debt instruments will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. ASU 2020-06 also requires use of the if-converted method in the diluted earnings per share calculation for convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years for smaller reporting companies, with early adoption permitted. The new standard will be effective for the Company on January 1, 2024 or at such earlier time where it is no longer a smaller reporting company. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments— Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The ASU introduced a new credit loss methodology, the Current Expected Credit Losses (“CECL”) methodology, which requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL methodology utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to maturity debt securities, trade receivables and other receivables measured at amortized cost at the time the financial asset is originated or acquired. Subsequent to the issuance of ASU 2016-13, the FASB issued several additional ASUs to clarify implementation guidance, provide narrow-scope improvements and provide additional disclosure guidance. In November 2019, the FASB issued an amendment making this ASU effective for fiscal years beginning after December 15, 2022 for smaller reporting companies. The Company adopted ASC 2016-13 on January 1, 2023 . The adoption of this standard did no t have a material impact on the Company's condensed consolidated financial statements. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force) (“ASU 2021-04”), which clarifies and reduces the diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. ASU 2021-04 is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2021-04 on January 1, 2022 . The adoption of this standard did no t have a material impact on the Company's condensed consolidated financial statements. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosure by Business Entities about Government Assistance (“ASU 2021-10”), which improves the transparency of government assistance received by certain business entities by requiring the disclosure of (1) the types of government assistance received; (2) the accounting for such assistance, and (3) the effect of the assistance on the business entity’s financial statements. ASU 2021-10 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. The Company adopted ASU 2021-10 on January 1, 2022 . The adoption of this standard did no t have a material impact on the Company’s condensed consolidated financial statements. |
