International Stem Cell Corporation Applauds Research Showing Parthenogenesis as a Potential Strategy for Treating Inherited Disease

International Stem Cell Corporation (OTCBB:ISCO),, applauds a recent announcement by researchers at Nationwide Children's Hospital showing the use of parthenogenetic stem cells as a potential strategy to treat genetic diseases such as Huntington's disease, beta thalassemia or tuberous sclerosis.

In a scientific paper entitled, "Gene therapy by allele selection in a mouse model of beta-thalassemia" recently published in the Journal of Clinical Investigation, a team of researchers from the Center for Molecular and Human Genetics (NationwideChildren's Hospital, Columbus, OH), the University of Pennsylvania, the University of North Carolina and the University of Minnesota led by John McLaughlin Ph.D., describe how they used a mouse model of an inherited blood disorder to show that parthenogenesis could be used to create "genetically clean" stem cells. These parthenogenetic stem cells demonstrated the ability to correct certain symptoms of such a disease.

Dr. Andrey Semechkin, CEO of ISCO, commented, "We at ISCO are particularly pleased to note this animal model research into the potential of parthenogenetic stem cells since ISCO has created method for creating immortal human parthenogenetic stem cell (hpSC) lines. We are constantly seeking ways to use such technology to treat human diseases, and this announcement is a positive indication showing the potential of parthenogenetic stem cells to treat certain types of autosomal dominant diseases such as particular forms of beta thalassemia or even Huntington's disease. We expect that the transition from animal models to human therapy using parthenogenetic cells will continue to evolve as ISCO continues to conduct its own therapeutic research and to collaborate with researchers across the world to discover new ways to use parthenogenesis and parthenogenetic stem cells to cure human disease. We have great hope that animal research such as that just reported will open new doors to human therapy and look forward to making our human parthenogentic lines available for such therapies."

ISCO created and patented the first proven technology to create human parthenogenetic stem cell lines from unfertilized human eggs. This technology has similar potential advantages as those described in the work done at Nationwide Children's Hospital; i.e., the creation of human parthenogenetic stem cells that could eliminate a defective copy of a gene and can be immune-matched to the egg donor. ISCO's technology has the additional ethical advantage of not harming a viable human embryo.

Dr Semechkin continues, "ISCO is actively conducting research on the creation and application of differentiated derivatives of hpSC for therapeutic use. Specifically, ISCO has initiated a number of pre-clinical animal studies utilizing both hepatocytes and separately retina pigment epithelium cells, derived from hpSC. ISCO's scientists were also the first to demonstrate the ability of hpSC to differentiate into neural cells and to develop approaches to obtain stable lines of parthenogenetic neural cells. These achievements open up the opportunity to assess the efficacy and safety of using parthenogenetic stem cells as a source to create neural cells for the treatment of diseases such as Parkinson's, Alzheimer's, and other neurodegenerative disorders. The work presented by Dr. McLaughlin once again confirms ISCO's unique position in the field of stem cell based therapies."

International Stem Cell Corporation is a California-based biotechnology company focused on the therapeutic applications of human parthenogenetic stem cells and the development and commercialization of cell-based research and cosmetic products. ISCO's core technology, parthenogenesis, results in 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 with minimal immune rejection after transplantation into hundreds of millions of individuals of differing sexes, ages and racial groups. This offers the potential to create the first true stem cell bank, UniStemCell™, while avoiding the ethical issue of using fertilized eggs. 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.
