International Stem Cell Corporation Announces New Stem Cell Manufacturing Technologies to Support its Therapeutic Programs

International Stem Cell Corporation (OTCBB: ISCO) today announced that the Company has developed new technologies to commercialize the use of human parthenogenetic stem cells (hpSC) to treat human diseases. The methods announced today are capable of producing populations of stem cells and their therapeutically valuable derivatives not only to a higher level of purity but also at a cost that is approximately several times lower than previously reported techniques.
ISCO's research team has developed a new method to derive high-purity populations of neural stem cells (NSC) from hpSC and further differentiate them into dopaminergic neurons. This method is capable of generating sufficient quantities of neuronal cells for ISCO's pre-clinical and clinical studies and is highly efficient as it requires substantially less time and labor in addition to using fewer costly materials than traditional methods. ISCO's technologies make possible the creation of billions of neuronal cells necessary for conducting such studies from a small batch of stem cells.
ISCO has also announced today that it has developed a new high-throughput cell culture method for growing human parthenogenetic stem cells (hpSC) in large quantities. This new technique is easily scalable and can produce the quantities of cGMP grade hpSC necessary for commercial and therapeutic applications.
"One of the most challenging issues in commercializing stem cell based treatments is creating high-purity populations of stem cell derivatives at a reasonable cost. I believe the new methods we have developed solve this important problem and help position us for future clinical studies," says Dr. Ruslan Semechkin, Vice President, R&D.
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 stem cell-based skin care products through its subsidiary Lifeline Skin Care ( More information is available at or follow us on Twitter @intlstemcell.

Forward-looking Statements
Statements pertaining to anticipated developments, the potential benefits of research programs and new manufacturing technologies, and other opportunities for the company and its subsidiaries, along with other statements about the future expectations, beliefs, goals, plans, or prospects expressed by management constitute forward-looking statements. Any statements that are not historical fact (including, but not limited to statements that contain words such as "will," "believes," "plans," "anticipates," "expects," "estimates,") should also be considered to be forward-looking statements. Forward-looking statements involve risks and uncertainties, including, without limitation, risks inherent in the development and/or commercialization of potential products and technologies regulatory approvals, need and ability to obtain future capital, application of capital resources among competing uses, and maintenance of intellectual property rights. Actual results may differ materially from the results anticipated in these forward-looking statements and as such should be evaluated together with the many uncertainties that affect the company's business, particularly those mentioned in the cautionary statements found in the company's Securities and Exchange Commission filings.
