OCEANSIDE, Calif. – March 2, 2010 – International Stem Cell Corporation (OTCBB: ISCO), www.internationalstemcell.com, announced today that human parthenogenetic stem cell lines (“hpSC”), created by scientists from its Research and Therapeutic Development Group, have demonstrated ability to maintain the essential properties of immortal stem cells throughout extended laboratory cultivation.
To date, ISCO has created 10 human parthenogenetic stem cell lines. One of these lines, named phSC-Hhom-4, has the most common set of HLA genes found in various U.S. population groups and may be useful to treat millions of people world-wide from a single cell line.
After more than one hundred passages over more than two years of continuous in vitro cultivation, the line phSC-Hhom-4 has maintained pluripotent stem cell properties and continues to be used in experiments to create therapeutic derivatives targeted for treatment of liver, cornea, retina and neurodegenerative diseases.
Dr. Andrey Semechkin, ISCO’s СЕО, says: “The ability of a stem cell line to maintain stable properties during long-term cultivation is one of the necessary properties that stem cells must have in order to be used in cell-based therapies. This property allows an almost unlimited increase in the amount of cells available for production of therapeutic derivatives”.
The differentiated derivatives of human parthenogenetic stem cells, obtained by ISCO scientists, promise to overcome the problem of immune-matching in tissue-replacement therapy. This is a significant differentiator from embryonic stem cells and a major reason why hpSC have the potential to become the first population-specific pluripotent stem cells available for use in the treatment of human diseases for different genders and racial groups across the world.
This achievement is another step toward the creation by ISCO of its proprietary “UniStem Cell Bank”™, confirming the importance of human parthenogenetic stem cells in possible therapeutic application and their ability to meet clinical transplant standards.
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). 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.
