International Stem Cell Begins Pre-Clinical Testing Of Its Parthenogenetic Stem Cells For Treatment Of Retinal Disease

OCEANSIDE, Calif., Jan 13, 2009 (BUSINESS WIRE) -- International Stem Cell Corporation (OTCBB: ISCO) has created layered human tissue from its unique parthenogenetic stem cells and transplanted this tissue into animals in pre-clinical trials to establish a potential new treatment for human retinal diseases, such as macular degeneration or retinitis pigmentosa.


"Intact layers of retinal progenitor cells have been shown to restore lost visual responses in several retinal degeneration rodent models," said Dr. Hans Keirstead, Co-Director of the Sue and Bill Gross Stem Cell Research Center at the University of California, Irvine. "Thus, we are developing intact retinal layers derived from International Stem Cell's human parthenogenetic stem cells which could become a sustainable, FDA-approved therapeutic supply for patients with retinal degenerative diseases."


ISCO's human parthenogenetic stem cells have the potential to treat human disease yet possess key medical and ethical advantages over other kinds of stem cell products. They can be matched to common immune types and thus reduce the chance of transplant rejection among large segments of the population. Because they are created from unfertilized human eggs, they do not require the destruction of human embryos.


"We are aggressively pushing forward safe treatments for human diseases using parthenogenetic stem cells," said Jeffrey Janus, President of International Stem Cell. "If we are successful in this work, our next step is to manufacture this layered human tissue for further tests, including human trials. This illustrates the strengths of combining scientific collaborations with outside researchers such as Dr. Keirstead with ISCO's science and cell manufacturing expertise."

ABOUT INTERNATIONAL STEM CELL CORPORATION (ISCO.OB):

International Stem Cell Corporation is a California biotechnology company focused on developing therapeutic and research products. ISCO's technology, Parthenogenesis, results in the creation of pluripotent human stem cell lines from unfertilized human eggs. ISCO scientists have created the first Parthenogenetic homozygous stem cell line (phSC-Hhom-4) that can be a source of therapeutic cells that will minimize immune rejection after transplantation into hundreds of millions of individuals of differing sexes, ages and racial groups. These advancements offer the potential to create the first true "Stem Cell Bank" and address ethical issues by eliminating the need to use or destroy fertilized embryos. ISCO also produces and markets specialized cells and growth media worldwide for therapeutic research through its subsidiary Lifeline Cell Technology.
