Under the 2004 Stock Option Plan (the 2004 Plan), stock awards were granted to employees, directors, and consultants of the Company, in the form of restricted stock and stock options. The amounts and terms of options granted were determined by the Company's compensation committee. The equity awards granted under the 2004 Plan generally vest over four years and have terms of up to ten years after the date of grant, and options are exercisable in cash or as otherwise determined by the board of directors. There are no shares available for future grants under the 2004 Plan, as grants from the 2004 Plan ceased upon the Company's initial public offering in April 2010.</div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;">&#160;</div><div style="text-align: justify; text-indent: 0pt; display: block; font-family: Times New Roman; margin-left: 36pt; font-size: 10pt; margin-right: 0pt;">The 2010 Stock Incentive and Option Plan (2010 Plan) became effective upon the closing of the Company's initial public offering.

The Company is updating its forecasted effective state tax rate to consider this impact on its deferred taxes and will continue to monitor and update the rate as necessary. &#160;Additionally, the Company has approximately a $8.3 million deferred tax asset related to Pennsylvania net operating loss carryforwards. &#160;The ultimate use of this deferred tax asset may be impacted by the size of operations remaining in Pennsylvania in the future. &#160;This deferred tax asset is currently offset by a full valuation allowance.</div><div style="text-align: justify;

therefore, the Company may not be able to take full advantage of these carryforwards for federal or state income tax purposes.</div></div> -6433000 -4386000 -13623000 -8645000 -200623000 <div><div style="text-align: justify;

Therefore, the Company recorded a liability as of March 1, 2011, the cease-use date, for the fair value of its obligations under the lease. The most significant assumptions used in determining the amount of the estimated lease liability are the potential sublease revenues and the credit-adjusted risk-free rate utilized to discount the estimated future cash flows.</div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;">&#160;</div><div style="text-align: justify; text-indent: 0pt; display: block; font-family: Times New Roman; margin-left: 36pt; font-size: 10pt; margin-right: 0pt;">In connection with the restructuring described in Note 8, the Company determined it was not likely to utilize substantially all of the leased office and manufacturing space in its East Norriton, Pennsylvania facility during the remainder of the lease term.

(the Company) was incorporated in Delaware on July 10, 2003. The Company is a regenerative medicine company focused on discovering, developing, manufacturing and commercializing a range of neo-organs, or products composed of living cells, with or without synthetic or natural materials, implanted or injected into the body to engraft into, regenerate, or replace a damaged tissue or organ.&#160;&#160;Using its Organ Regeneration Platform, the Company creates these neo-organs using a patient's own cells, or autologous cells.&#160;&#160;The Company believes its proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. The Company's product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications.&#160;&#160;In addition, the Company's neo-organs are designed to avoid the need to substitute other tissues of the body for a purpose to which they are poorly suited.</div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;">&#160;</div><div style="text-align: justify; text-indent: 0pt; display: block; font-family: Times New Roman; margin-left: 36pt; font-size: 10pt; margin-right: 0pt;">Building on its clinical and preclinical experience, the Company is initially leveraging its Organ Regeneration Platform to develop its Neo-Urinary Conduit for bladder cancer patients who are in need of a urinary diversion and its Neo-Kidney Augment for patients with advanced chronic kidney disease. The Company operates as a single business segment. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of product candidate development; technological uncertainty; dependence on collaborative partners; uncertainty regarding patents and proprietary rights; comprehensive government regulations; having no commercial manufacturing experience, marketing or sales capability or experience; and dependence on key personnel.</div></div> <div><div><table cellpadding="0" cellspacing="0" style="width: 100%; font-family: times new roman; font-size: 10pt;"><tr valign="top"><td align="right" style="width: 36pt;"><div style="display: inline; font-family: Times New Roman; font-size: 10pt; font-weight: bold;">(3)&#160;&#160;</div></td><td><div style="text-align: justify; text-indent: 0pt; font-family: Times New Roman; margin-left: 0pt; font-size: 10pt; font-weight: bold; margin-right: 0pt;">Basis of Presentation and Reverse Stock Split</div></td></tr></table></div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;">&#160;</div><div style="text-align: justify; text-indent: 0pt; display: block; font-family: Times New Roman; margin-left: 36pt; font-size: 10pt; margin-right: 0pt;">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.
