Basis of Presentation	'
	Note 2. Basis of Presentation
	The accompanying unaudited financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.    Accordingly, they do not include all of the information and footnote disclosures required by GAAP for complete consolidated financial statements.  In the opinion of management, all adjustments (consisting of normal recurring adjustments and the impact of restatements on prior periods discussed below) considered necessary for a fair presentation have been included.  These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, as amended, filed with the Securities and Exchange Commission (“SEC”) as discussed below.  The results of the Company’s operations for any interim period are not necessarily indicative of the results of operations for any other interim period or full year.
	On May 6, 2014, the Audit Committee of the Company’s Board of Directors, in connection with an internal review initiated by Company management, concluded that, because of a misapplication of the accounting guidance related to certain of the Company’s warrants, the Company’s previously issued consolidated financial statements for all periods beginning with the quarterly period ended September 30, 2011 through December 31, 2013 should no longer be relied upon.  On June 2, 2014, the Company restated all affected interim and annual periods in its Annual Report on Form 10-K/A (Amendment No. 2) for the fiscal year ended December 31, 2013 in an SEC approved “omnibus” filing.  As such, the comparative information provided for the year ended December 31, 2013 and the three and six months ended June 30, 2013 contained in the preceding financial statements and the accompanying footnotes reflect these previously restated amounts.
	The prior year financial statements contain certain reclassifications to the results of operations for the three and six months ended June 30, 2013 to conform to the presentation for the three and six months ended June 30, 2014 on this Form 10-Q.  These reclassifications were made in conjunction with the Company’s shift in focus away from its commercial product LAVIV® and to further research and development of the underlying azficel-T process.
	For the three and six months ended June 30, 2014, amortization expense of approximately $0.1 million and $0.3 million, respectively, was included in research and development expense on the Consolidated Statements of Operations.  For the three and six months ended June 30, 2013, amortization expense of approximately $0.1 million and $0.3 million, respectively, was reclassed from cost of sales to research and development expense on the Consolidated Statements of Operations to conform to the current presentation.  For the three and six months ended June 30, 2014, Food and Drug Administration (“FDA”) license fees related to the Company’s Biologics License Application (“BLA”) of approximately $0.2 million and $0.3 million, respectively, were included in research and development expense on the Consolidated Statements of Operations.  For the three and six months ended June 30, 2013, FDA license fees of approximately $0.2 million and $0.3 million, respectively, were reclassified from selling, general and administrative expense to research and development expense on the Consolidated Statements of Operations to conform to the current presentation.

Summary of Significant Accounting Policies	'
Summary of Significant Accounting Policies	'
	Note 3. Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes.  In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows.  Actual results may differ materially from those estimates.
	Cost of Sales
	Cost of sales includes the costs related to the processing of cells for LAVIV®, including direct and indirect costs.  Beginning in 2014, cost of sales is accounted for using a standard cost system which allocates the direct costs associated with our manufacturing, facility, quality control, and quality assurance operations as well as overhead costs.  The principal reason for the relatively small level of revenue as compared to the cost of sales is that we changed corporate strategy in 2013 to de-emphasize sales of azficel-T into the aesthetic markets, and transitioned our business strategy to focus on high-value therapeutic applications for treatment of unmet medical conditions of the skin and connective tissue.
	Research and Development Expenses
	Research and development costs are expensed as incurred and include salaries and benefits, costs paid to third party contractors to perform research, conduct clinical trials, develop and manufacture drug materials and delivery devices, and a portion of facilities cost.  Research and development costs also include costs to develop manufacturing, cell collection and logistical process improvements.
	Clinical trial costs are a significant component of research and development expenses and include costs associated with third party contractors.  Invoicing from third party contractors for services performed can lag several months.  The Company accrues the costs of services rendered in connection with third party contractor activities based on its estimate of management fees, site management and monitoring costs and data management costs.
	Property and Equipment
	Property and equipment is carried at acquisition cost less accumulated depreciation.  Depreciation is computed on a straight-line basis over the estimated useful life of the asset.  The cost of repairs and maintenance is charged to expense as incurred.  As of December 31, 2013, the useful life for all property and equipment was three years, except for leasehold improvements which were depreciated over the remaining lease term or the life of the asset, whichever was shorter.  In the first quarter of 2014, the Company adjusted its useful lives to reflect the expected consumption of the economic benefit of these assets as noted in the following table:
	Property and equipment category	Useful life
	Laboratory equipment	6 years
	Computer equipment and software	3 years
	Furniture and fixtures	10 years
	Leasehold improvements	Lesser of remaining lease term or life of asset
	In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) ASC 250 Accounting Changes and Error Corrections, the Company accounted for this change in useful lives as a change in estimate, with prospective application only.  The impact of this change in estimate on depreciation expense for the three and six months ended June 30, 2014 was immaterial to the results on the Consolidated Statements of Operations.
	Intangible Assets
	Intangible assets are research and development assets related to the Company’s primary study on azficel-T that was recognized upon emergence from bankruptcy.  Azficel-T has three current or target indications: the Company’s commercial product, LAVIV®, a clinical development program for restrictive burn scarring and a clinical development program for vocal cord scarring.  Effective January 1, 2012, the Company launched LAVIV® and as a result, the research and development intangible assets related to the Company’s primary study were considered to be finite-lived intangible assets and are being amortized over 12 years.
	Finite-lived intangible assets are recorded at cost, net of accumulated amortization and, if applicable, impairment charges.  Amortization of finite-lived intangible assets is provided over their estimated useful lives on a straight-line basis.  In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 360-10-35 Impairment or Disposal of Long-Lived Assets, the Company reviews its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  There was no impairment expense recognized for either the three or six months ended June 30, 2014 or 2013.
	Income Taxes
	Income taxes are recorded in accordance with ASC Topic 740, Income Taxes (“ASC 740”), which provides for reporting of amounts that are currently payable and also for deferred taxes using an asset and liability approach.  The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.  Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740.  When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized.  The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2013 and June 30, 2014, the Company did not have any uncertain tax positions.
	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” under ASC Topic 606 which supersedes the current revenue recognition requirements under ASC Topic 605, “Revenue Recognition”.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.  It also provides a five step approach to achieve this principle.  For public entities, the new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period.  Early application is not permitted.  Based on the Company’s current financial operations, the Company anticipates the potential impact of ASU No. 2014-09 to be immaterial to its financial statements.
	Subsequent Events
	The Company evaluates all subsequent events, through the date the consolidated financial statements are issued, to determine if there are any events that require disclosure.  No such events have been identified through the date of this filing.

Warrants	'
	Note 5. Warrants
	The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement.  Stock warrants are accounted for as a derivative in accordance with Accounting Standards Codification 815, Derivatives and Hedging (“ASC 815”) if the stock warrants contain “down-round protection” or other terms that could potentially require “net cash settlement” and therefore, do not meet the scope exception for treatment as a derivative.  Since “down-round protection” is not an input into the calculation of the fair value of the warrants, the warrants cannot be considered indexed to the Company’s own stock which is a requirement for the scope exception as outlined under ASC 815.  Warrant instruments that could potentially require “net cash settlement” in the absence of express language precluding such settlement and those which include “down-round provisions” are initially classified as derivative liabilities at their estimated fair values, regardless of the likelihood that such instruments will ever be settled in cash.  The Company will continue to classify the fair value of the warrants that contain “down-round protection” or “net cash settlement” as a liability until the warrants are exercised, expire or are amended in a way that would no longer require these warrants to be classified as a liability.
	The following table summarizes outstanding warrants to purchase common stock as of:

	There were no warrants exercised or cancelled during the six months ended June 30, 2014.
	Liability-classified Warrants
	The foregoing warrants are recorded as liabilities at their estimated fair value at the date of issuance, with the subsequent changes in estimated fair value recorded in other income (expense) in the Company’s statements of operations in each subsequent period.  The change in the estimated fair value of our warrant liability for the three and six months ended June 30, 2014 resulted in non-cash income of approximately $4.0 million and $1.0 million, respectively.  The change in the estimated fair value of our warrant liability for the three and six months ended June 30, 2013 resulted in non-cash expense of approximately $8.8 million and $7.5 million, respectively.  The Company utilizes the Monte Carlo simulation valuation method to value the liability classified warrants.
	The estimated fair value of these warrants is determined using Level 3 inputs.  Inherent in the Monte Carlo valuation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.  The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.  The expected life of the warrants is assumed to be equivalent to their remaining contractual term.  The dividend rate is based on the historical rate, which the Company anticipates will remain at zero.
	The estimated fair value of these warrants also require Level 3 inputs which are based on the Company’s estimates of the probability and timing of potential future financings and qualifying fundamental transactions.  The other assumptions used by the Company are summarized in the following table:
		June 30, 2014		June 30, 2013
	Weighted average remaining expected life (years)	3		3.6
	Interest rate	0.9	%	1	%

	Note 6. Fair Value Measurements
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The Company adopted the accounting guidance on fair value measurements for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in one of the following three categories:
	·         Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	·         Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.
	·         Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
	The following fair value hierarchy table presents information about each major category of the Company’s financial assets and liability measured at fair value on a recurring basis as of June 30, 2014 and December 31, 2013:
		Fair value measurement using

	The reconciliation of warrant liability measured at fair value on a recurring basis using unobservable inputs (Level 3) is as follows:
		Warrant
	($ in thousands)	Liability
	Balance at December 31, 2013	$	15,216
	Exercise of warrants	—
	Change in fair value of warrant liability	(958		)
	Balance at June 30, 2014	$	14,258
	The fair value of the warrant liability is based on Level 3 inputs. For this liability, the Company developed its own assumptions that do not have observable inputs or available market data to support the fair value.  See Note 5 for further discussion of the warrant liability.  The Company believes that the fair values of our current assets and current liabilities approximate their reported carrying amounts. There were no transfers between Level 1, 2 and 3 during the periods presented.

	The Company’s board of directors (the “Board”) adopted the 2009 Equity Incentive Plan (as amended to date, the “Plan”) effective September 3, 2009.  The Plan is intended to further align the interests of the Company and its stockholders with its employees, including its officers, non-employee directors, consultants and advisors by providing incentives for such persons to exert maximum efforts for the success of the Company.  The Plan allows for the issuance of up to 5,600,000 shares of the Company’s common stock.  In addition, there were 206,000 options issued outside of the Plan to consultants.
	The types of awards that may be granted under the Plan include options (both nonqualified stock options and incentive stock options), stock appreciation rights, stock awards, stock units and other stock-based awards.  The term of each award is determined by the Compensation Committee of the Board at the time each award is granted, provided that the terms of options do not exceed ten years.  Vesting schedules for the stock options vary, but generally vest 25% per year, over four years.  The Plan had 3,384,286 options available for grant as of June 30, 2014.
	Total share-based compensation expense recognized using the straight-line attribution method in the Consolidated Statements of Operations is as follows:

	The total fair value of shares vested during the six months ended June 30, 2014 was approximately $0.5 million.  As of June 30, 2014, there was approximately $3.0 million of total unrecognized compensation cost, related to time-based non-vested stock options.  That cost is expected to be recognized over a weighted-average period of 4.2 years.  As of June 30, 2014, there was no unrecognized compensation expense related to performance-based, non-vested non-employee options.
	During the six months ended June 30, 2014 and 2013, the weighted average fair market value of the options granted was $2.74 and $2.07, respectively.  The fair market value of the options was computed using the Black-Scholes option-pricing model with the following key weighted average assumptions for the six months ended as of the dates indicated:

	Note 8.  Loss Per Share
	Basic loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during a period.  The diluted loss per share calculation gives effect to dilutive options, warrants, convertible notes, convertible preferred stock, and other potential dilutive common stock including selected restricted shares of common stock outstanding during the period.  Diluted loss per share is based on the treasury stock method and includes the effect from potential issuance of common stock, such as shares issuable pursuant to the exercise of stock options, assuming the exercise of all in-the-money stock options.  Common share equivalents have been excluded where their inclusion would be anti-dilutive.

	Preferred stock
	The Company is authorized to issue 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges, and restrictions thereof.  These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock.  The issuance of the Company’s preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation.  In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control of the Company or other corporate action.  There were no preferred shares issued or outstanding as of June 30, 2014 or December 31, 2013.
	Common stock
	In connection with the execution of the Second Amendment to the Exclusive Channel Collaboration Agreement (the “Second Amendment”) on January 10, 2014 between the Company and Intrexon Corporation (“Intrexon”), the Company entered into a Supplemental Stock Issuance Agreement with Intrexon.  The Company agreed to issue to Intrexon, who is an affiliate of NRM VII Holdings I, LLC, the Company’s largest shareholder, a number of shares of Company common stock based on a per share value of the closing price of the Company’s common stock on the NYSE MKT on the day prior to execution of the Supplemental Stock Issuance Agreement (the “Supplemental Access Fee Shares”).  The Supplemental Access Fee Shares were issued upon the satisfaction of customary closing conditions, including the approval for the listing of the Supplemental Access Fee Shares on the NYSE MKT.  The closing took place on January 24, 2014.  The Company recorded a research and development expense in the first quarter of 2014 for the shares issued to Intrexon as a technology access fee.  1,024,590 shares were issued based on a per share value of $5.03 based on the closing price of the Company’s common stock on the closing date, totaling approximately $5.2 million.  For additional discussion on the Company’s collaboration with Intrexon, see Note 11.

	In accordance with ASC Topic No. 270 “Interim Reporting” and ASC Topic No. 740 “Income Taxes”, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate and then apply that rate in providing for income taxes on a current year-to-date (interim period) basis.  For the six months ended June 30, 2014 and 2013, the Company recorded no tax expense or benefit due to the expected current year loss and its historical losses.  The Company had not recorded its net deferred tax asset as of either June 30, 2014 or December 31, 2013, because it maintains a full valuation against all deferred tax assets as management has determined that it is not more likely than not that the Company will realize these future tax benefits.

	Note 11. Collaboration with Related Party
	Intrexon is an affiliate of our largest shareholder, NRM VII Holdings I, LLC.  In addition, two of our seven directors are also affiliates of NRM VII Holdings I, LLC.
	On January 10, 2014, the Company and Intrexon entered into a Second Amendment to the parties’ Exclusive Channel Collaboration Agreement dated October 5, 2012, as previously amended on June 28, 2013 (the “Channel Agreement” and such previous amendment, the “First Amendment”).  The Channel Agreement provides for a “channel collaboration” arrangement governing a strategic collaboration for the development and commercialization of genetically-modified and non-genetically-modified autologous fibroblasts and autologous dermal cells in the United States.  The Channel Agreement originally granted the Company an exclusive license to use proprietary technologies and other intellectual property of Intrexon to research, develop, use, import, export, make, have made, sell, and offer for sale certain products in the field in the United States.
	Pursuant to the Channel Agreement and Amendments, the Company engaged Intrexon for support services for the development of new products covered under the Channel Agreement and Amendments, and will reimburse Intrexon for its fully-loaded cost for time and materials for transgenes, cell processing, or other work performed by Intrexon for such research and manufacturing. For the three and six months ended June 30, 2014, the Company incurred expenses of $0.7 million and $1.8 million, respectively, for work performed.  For the three and six months ended June 30, 2013, the Company incurred expenses of $0.6 million and $1.0 million, respectively, for work performed.  As of June 30, 2014 and December 31, 2013, the Company had outstanding trade payables with Intrexon of $0.2 million and $1.3 million, respectively.

Summary of Significant Accounting Policies	'
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes.  In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows.  Actual results may differ materially from those estimates.
Cost of Sales	'
	Cost of Sales
	Cost of sales includes the costs related to the processing of cells for LAVIV®, including direct and indirect costs.  Beginning in 2014, cost of sales is accounted for using a standard cost system which allocates the direct costs associated with our manufacturing, facility, quality control, and quality assurance operations as well as overhead costs.  The principal reason for the relatively small level of revenue as compared to the cost of sales is that we changed corporate strategy in 2013 to de-emphasize sales of azficel-T into the aesthetic markets, and transitioned our business strategy to focus on high-value therapeutic applications for treatment of unmet medical conditions of the skin and connective tissue.
Research and Development Expenses	'
	Research and Development Expenses
	Research and development costs are expensed as incurred and include salaries and benefits, costs paid to third party contractors to perform research, conduct clinical trials, develop and manufacture drug materials and delivery devices, and a portion of facilities cost.  Research and development costs also include costs to develop manufacturing, cell collection and logistical process improvements.
	Clinical trial costs are a significant component of research and development expenses and include costs associated with third party contractors.  Invoicing from third party contractors for services performed can lag several months.  The Company accrues the costs of services rendered in connection with third party contractor activities based on its estimate of management fees, site management and monitoring costs and data management costs.
Property and Equipment	'
	Property and Equipment
	Property and equipment is carried at acquisition cost less accumulated depreciation.  Depreciation is computed on a straight-line basis over the estimated useful life of the asset.  The cost of repairs and maintenance is charged to expense as incurred.  As of December 31, 2013, the useful life for all property and equipment was three years, except for leasehold improvements which were depreciated over the remaining lease term or the life of the asset, whichever was shorter.  In the first quarter of 2014, the Company adjusted its useful lives to reflect the expected consumption of the economic benefit of these assets as noted in the following table:
	Property and equipment category	Useful life
	Laboratory equipment	6 years
	Computer equipment and software	3 years
	Furniture and fixtures	10 years
	Leasehold improvements	Lesser of remaining lease term or life of asset
	In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) ASC 250 Accounting Changes and Error Corrections, the Company accounted for this change in useful lives as a change in estimate, with prospective application only.  The impact of this change in estimate on depreciation expense for the three and six months ended June 30, 2014 was immaterial to the results on the Consolidated Statements of Operations.
Intangible Assets	'
	Intangible Assets
	Intangible assets are research and development assets related to the Company’s primary study on azficel-T that was recognized upon emergence from bankruptcy.  Azficel-T has three current or target indications: the Company’s commercial product, LAVIV®, a clinical development program for restrictive burn scarring and a clinical development program for vocal cord scarring.  Effective January 1, 2012, the Company launched LAVIV® and as a result, the research and development intangible assets related to the Company’s primary study were considered to be finite-lived intangible assets and are being amortized over 12 years.
	Finite-lived intangible assets are recorded at cost, net of accumulated amortization and, if applicable, impairment charges.  Amortization of finite-lived intangible assets is provided over their estimated useful lives on a straight-line basis.  In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 360-10-35 Impairment or Disposal of Long-Lived Assets, the Company reviews its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  There was no impairment expense recognized for either the three or six months ended June 30, 2014 or 2013.
Income Taxes	'
	Income Taxes
	Income taxes are recorded in accordance with ASC Topic 740, Income Taxes (“ASC 740”), which provides for reporting of amounts that are currently payable and also for deferred taxes using an asset and liability approach.  The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.  Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740.  When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized.  The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2013 and June 30, 2014, the Company did not have any uncertain tax positions.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” under ASC Topic 606 which supersedes the current revenue recognition requirements under ASC Topic 605, “Revenue Recognition”.  The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.  It also provides a five step approach to achieve this principle.  For public entities, the new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period.  Early application is not permitted.  Based on the Company’s current financial operations, the Company anticipates the potential impact of ASU No. 2014-09 to be immaterial to its financial statements.
Subsequent Events	'
	Subsequent Events
	The Company evaluates all subsequent events, through the date the consolidated financial statements are issued, to determine if there are any events that require disclosure.  No such events have been identified through the date of this filing.
