Subsequent Events	Note 13—Subsequent Events On July 17, 2013, the $2 million subscription receivable was received. On June 28, 2013, the Company and Intrexon Corporation (“Intrexon”) entered into a First Amendment (“Amendment”) to the parties’ Exclusive Channel Collaboration Agreement (the “Channel Agreement”) dated October 5, 2012. 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 develop and commercialize certain products in the Field in the United States. The “Field” in the Channel Agreement originally included: (a) the enhanced production and purification of non-genetically modified autologous fibroblasts for all aesthetic and therapeutic indications; (b) the enhanced production and purification of non-genetically modified autologous dermal cells for aesthetic and therapeutic treatment of dermal, vocal cord, and periodontal indications; (c) the development of genetically modified autologous fibroblasts for all aesthetic and therapeutic indications; and (d) the development of genetically modified autologous dermal cells for aesthetic and therapeutic treatment of dermal, vocal cord, and periodontal indications. Pursuant to the Amendment, the “Field” in the Channel Agreement was amended to add autologous human fibroblasts genetically modified to express a therapeutic protein and/or bioactive RNA for the treatment of autoimmune and non-infectious inflammatory disorders that manifest in cutaneous tissues, fascia and/or muscle. The remainder of the Channel Agreement was unchanged and the terms of the Channel Agreement will apply to the amended “Field.” In connection with the execution of the Amendment, on June 28, 2013, the Company entered into a Supplemental Stock Issuance Agreement with Intrexon pursuant to which 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 valued at $7.5 million based on a per share value of $6.03 per share, which was 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”), which issuance will be deemed paid in partial consideration for the execution and delivery of the Amendment. 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 July 26, 2013. We will record a fair value of $6.4 million for the shares issued to Intrexon for the closing of the Supplemental Stock Issuance Agreement as a research and development expense in the third quarter of 2013.
