International Stem Cell Corporation Updates on 2010 Initial Product Launch of its Lifeline Skin Care Products

International Stem Cell Corporation (OTCBB:ISCO), http://www.internationalstemcell.com, announced today that its wholly owned subsidiary Lifeline Skin Care, Inc. ("LSC"), has now completed its evaluation of the highly successful trial launch of its new stem cell skin care product line in November and December 2010, and will move forward with its general marketing program.

Lifeline Skin Care products contain parthenogenetic stem cell extract and were developed by the ISCO research team in collaboration with world recognized cosmetic chemists. The breakthrough products deliver leading advances in skin rejuvenation technology that help to prevent and repair damaged skin. The products are available through our online store at http://www.lifelineskincare.com.

"Sales to date have greatly exceeded our expectations for the trial launch. These initial sales resulted from a very limited product offering made to subscribers of only one of the several newsletters of our marketing partner, John Mauldin, plus a small direct mailing to interested parties and ISCO's shareholders who had signed up for general corporate information through the ISCO website," said Dr. Ruslan Semechkin, CEO of Lifeline Skin Care.

Lifeline Skin Care is now ready to move forward to the next phase of distribution, which will commence near the end of March. That phase will consist initially of a customer solicitation conducted by John Mauldin's specialty Internet and direct response marketing organization. "We almost never endorse or sell a retail product," said Mr. Mauldin, "but the results of both our informal testing and the company's formal studies have convinced us that the Lifeline Skin Care products really are a game-changing advance in skin care. I have not seen such a strong response in online marketing in the last ten years. We are all very excited and proud to be involved."

Kenneth Aldrich, Chairman of ISCO, issued a cautionary comment to its investors. "We are incredibly excited by the prospects of this new product from our Lifeline Skin Care subsidiary. Selling over 7,000 bottles through a very limited trial launch, as we have done, represents a significant first step, but it would be imprudent for us to base projections of future sales or profits on a sample base of this size."

ISCO investors should note that under ISCO's current revenue recognition policy, a large portion of the Q-4 2010 sales will not be included as revenue in the financial statements for the year ended December 31, 2010. Sales of these products meet our revenue recognition criteria after our 30 day product guarantee period has been completed.

ABOUT INTERNATIONAL STEM CELL CORPORATION (ISCO.OB)

International Stem Cell Corporation is a California-based biotechnology company focused on therapeutic and research products. ISCO's core technology, parthenogenesis, results in creation of pluripotent human stem cells from unfertilized oocytes (eggs). These proprietary cells avoid ethical issues associated with use or destruction of viable human embryos and, unlike most other major stem cell types, can be immune matched and be a source of therapeutic cells with minimal rejection after transplantation into hundreds of millions of individuals of differing racial groups. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary, Lifeline Cell Technology, and has developed cell based skin care products through its subsidiary, Lifeline Skin Care. ISCO is advancing novel human stem cell-based therapies where cells have been proven to be efficacious but traditional small molecule and protein therapeutics have not. More information is available on ISCO's website, http://www.internationalstemcell.com.
