International Stem Cell Corporation Begins Pre-Clinical Trials on Human Corneal Epithelial Cells

Trials Designed to Improve Laser Eye Surgery Outcomes

International Stem Cell Corporation (OTCBB:ISCO), the first company to perfect a method of creating human "parthenogenetic" stem cells from unfertilized eggs, is planning pre-clinical trials aimed at applying its laboratory-grown human corneal epithelial cells to improve photorefractive keratectomy (PRK), a form of corrective laser eye surgery.

These trials are the first step toward Food and Drug Administration (FDA) clinical trials to test the efficacy of using ISCO cells to improve healing after corneal surgery, and are part of the company's efforts to increase the clinical utility of its discoveries in culturing corneal cells and tissues.

This work is being done in collaboration with Dr. Paul H. Chen, M.D., who has developed the cell transfer technology. Dr. Chen is an eye surgeon at North County Laser Eye Associates, and he is on staff at Scripps Memorial La Jolla and Scripps Encinitas Hospitals.

"This collaboration is an excellent opportunity for ISCO to use its cell culture and manufacturing expertise to create therapeutic human cells that can enter the market relatively quickly and improve patient's quality of life," said Jeffrey Janus, ISCO's president. "We are fortunate to be working with Dr. Chen on this exciting project."

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.
