International Stem Cell Corporation to Present Immune Matching Research Advances at Cell Science and Stem Cell Research 2011 Conference

Executives from International Stem Cell Corporation (OTCBB:ISCO), a biotechnology company specializing in the research and development of stem cell-based therapies, will be presenting advances made in its research programs related to the use of immune-matched patient-specific parthenogenetic stem cells for neurological applications and genetic liver diseases at Cell Science 2011 in Philadelphia on November 29^th.

Vice President Ruslan Semechkin, Ph.D., will open the conference and discuss the latest trends in the use of stem cells to treat diseases of the central nervous system. A follow-on presentation will demonstrate that functional dopaminergic neurons can be successfully obtained from human parthenogenetic stem cells. Alina Ostrowska, Ph.D., the Company's Director of Translational Research, will present a new method of obtaining highly-enriched cultures of hepatocyte-like cells from pluripotent human stem cells.

Dr Semechkin comments, "I'm honored to be opening this conference and to be debating the latest advances in stem cell therapies. ISCO will also be presenting the most recent results from two of our most important research programs, where we continue to further characterize our parthenogenetic stem cell lines and their ability to form functioning liver-like cell and functioning neuron-like cells."

ISCO uses unfertilized oocytes to create human parthenogenetic stem cells, an approach that offers a number of distinct advantages over other types of human pluripotent stem cells. Like human embryonic stem cells (hESCs), hpSCs are pluripotent, i.e. they have the capacity to become almost any cell type in the body, yet avoid ethical issues associated with use or destruction of viable human embryos. Unlike hESCs, hpSCs can be created in a form such that they can be immunologically matched to millions of individuals. ISCO maintains the world's largest collection of research-grade hpSC lines.

About International Stem Cell Corporation

International Stem Cell Corporation is focused on the therapeutic applications of human parthenogenetic stem cells (hpSCs) and the development and commercialization of cell-based research and cosmetic products. ISCO's core technology, parthenogenesis, results in the creation of pluripotent human stem cells from unfertilized oocytes (eggs). hpSCs avoid ethical issues associated with the use or destruction of viable human embryos. ISCO scientists have created the first parthenogenic, homozygous stem cell line that can be a source of therapeutic cells for hundreds of millions of individuals of differing genders, ages and racial background with minimal immune rejection after transplantation. hpSCs offer the potential to create the first true stem cell bank, UniStemCell™. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary Lifeline Cell Technology, and cell-based skin care products through its subsidiary Lifeline Skin Care.
