International Stem Cell Corporation and The Automation Partnership Enter into Strategic Alliance to Automate Cornea Tissue Production

OCEANSIDE, CA – May 18, 2010 – International Stem Cell Corporation (ISCO.OB), www.intlstemcell.com, announced today that it had entered into a strategic alliance with The Automation Partnership (TAP), www.automationpartnership.com, to automate and scale up the production of stem cell-derived human corneal tissue. The alliance has been formed to create instrumentation for ISCO and its partners and affiliates to produce development and commercial volumes of donor tissue for cornea transplantation and to reduce the use of animals and animal eyes in safety testing of drugs, chemicals and consumer products.

Cornea-related loss or reduction of vision can be caused by physical injury, infections and degenerative diseases. In cases where cornea replacement is indicated, current medical practice typically involves a one-two hour outpatient procedure under local anesthesia using full or partial corneas from healthy human cadavers. 10 million people worldwide are candidates for such treatment, primarily in Asia and Europe where there is significant quantitative and qualitative shortage of human cornea donation.

Global efforts are underway to transition from the use of live animals and excised animal eyes to test drugs, chemicals and consumer products. For example, Europe’s Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) estimates a need to spend €270M and use 160,000 animals for eye safety testing alone to catch up with the back-log of insufficiently tested agents. In the US, the National Institutes of Health (NIH) and the Environmental Protection Agency (EPA) have launched a five-year program dedicated to finding new, non-animal technologies for toxicity testing of chemical compounds.

ISCO has discovered and filed for patents on a cell culture process for the synthesis of standardized, human, corneal tissue using stem cells. Histology, permeability and optical testing has demonstrated compatibility with natural corneas. Efforts are ongoing to further characterize this tissue and standardize and scale up its synthesis. Automation is necessary to produce sufficient, reproducible tissue for development and commercialization of the therapeutic and toxicity testing applications.

Brian Lundstrom, ISCO’s President, says: “Given the substantial unmet therapeutic and toxicology testing needs for human corneal tissue, ISCO has embarked on a focused effort to advance this technology with international investors, eye clinics, and development and commercialization partners. After reviewing a range of potential cell culture automation companies, we are very pleased that TAP has agreed to contribute their over twenty years of experience towards this goal.”

David Newble, TAP’s CEO says: “TAP has successfully installed and supported over 160 automated cell culture systems worldwide and continues to design new and customize existing equipment for cell culture and other emerging life science applications. The opportunity to join forces with ISCO in the cornea tissue area will enable us to contribute solutions for clear biomedical needs while also creating new technology and knowhow that will be useful in other applications downstream.”

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 (hpSCs) 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.

INTERNATIONAL STEM CELL CORPORATION’S CHAIRMAN DISCUSSES CREATION OF CORNEA IN A PETRI DISH IN DECEMBER 11, 2009 EDITION OF DISCOVERY NEWS

OCEANSIDE, CA – December 15, 2009 –International Stem Cell Corporation (OTCBB:ISCO), www.intlstemcell.com, a company creating human stem cell lines from unfertilized eggs, disclosed today that its previously announced creation of human, cornea-like tissue in a petri dish had become the subject of an article titled “Biotech Could Take Rabbits Off Lab Duty” in the December 11, 2009 edition of Discovery News.

In the article, reporter Alyssa Danigelis writes about how, while growing stem cells in the lab using blastocysts, researchers at International Stem Cell spotted something in the waste products usually discarded from the petri dish that turned out to be a tiny translucent structure of cells that resembled a human cornea.

This little ball of cells, the article explained, might actually spare animals from lab testing and be used for transplants in humans. Many cosmetics, drug, and chemical companies still put their products in live rabbits' eyes for safety testing, a process that is not only awful for the animals, but time-consuming and expensive.

Mr. Kenneth Aldrich, ISCO’s Chairman, was reported as saying that an initial round of testing with the ISCO corneas demonstrated that they have the same permeability as the rabbit eyes. The lab-grown corneas may also have the potential to be transplanted into humans one day. He went on to mention that this could make a big difference in countries where it's difficult to get refrigerated donor corneas to patients in time. Currently the company is repeating a round of validation testing to confirm the permeability results.
