International Stem Cell Corporation (OTCBB: ISCO),  http://www.internationalstemcell.com,         announced today that the recent presentation entitled "Hepatocyte-like        cells derived from patient-specific human parthenogenetic stem cells        possess functions of mature human hepatocytes including P450 activity"        has been identified as an "AASLD Presidential Poster of Distinction" in        the Stem Cells session of The Liver Meeting,  the 61st Annual        Meeting of the American Association for the Study of Liver Diseases        (AASLD),  in Boston,  MA,  one of the most prestigious annual medical and        scientific conferences.  The abstract of the presentation is published in        the peer-reviewed supplement to Hepatology,  volume 52,  number 4 (SUPPL),         Oct.  2010,  pg 965A,  the official journal of the AASLD.      
       ISCO's CEO Andrey Semechkin,  Ph.D.,  said,  "For our cell biologists to        have received this award from the leading society in the U.S.  focused on        treating liver diseases,  demonstrates the high caliber of research being        carried out at ISCO,  and that human parthenogenetic stem cells and their        differentiated derivatives are becoming of greater interest to the        medical research community as a potential source of therapeutically        valuable cells."     
       ISCO also announced today the initiation of the first in a series of        animal studies designed to demonstrate whether hepatocytes and their        progenitors derived from the human parthenogenetic stem cells show any        disease modifying activity in vivo.     
       Dr.  Nikolay Turovets,  ISCO's Director of Research and Therapeutic        Development said,  "ISCO's continued focus on therapeutic development is        critical to show that hepatocytes derived from stem cells can reproduce        missing liver function in a diseased organism.  Our first series of        experiments are designed to test the ability of our cells to engraft and        survive in vivo.  A second set of experiments will investigate the        functional activity of successfully engrafted cells.  Data from these        studies will also be used to guide the development of future IND        submissions."     
       In other research news,  ISCO announced that a grant in which ISCO is a        partner,  was recently funded by the Qualified Therapeutic Discovery        Project Grants Program created under the healthcare reform legislation        enacted last March.  The study is led by Paul H.  Chen,  M.D.  to        investigate healing after corneal surgery using ISCO's corneal        epithelial cells developed by ISCO's wholly-owned subsidiary Lifeline        Cell Technology.  ISCO's cells,  combined with a proprietary surgical        device developed by Dr.  Chen,  may provide safer and better long term        results than LASIK.  By utilizing ISCO's human corneal cells,  ISCO and        Dr.  Chen believe that cellular enhanced PRK could eventually replace        LASIK for many of the hundreds of thousands of patients who require        corrective eye surgery.     
       According to Dr.  Chen,  "This collaborative work with ISCO could lead to        a safer and more effective treatment that hopefully will provide quicker        visual recovery,  less pain,  and an improved refractive correction        outcome."     
       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 is developing a line of        cosmeceutical products via 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.
