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^(TM), 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.

FORWARD-LOOKING

Statements pertaining to anticipated technological developments and therapeutic applications, and other opportunities for the company and its subsidiary, 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, uncertainty in the results of clinical trials or 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. The company disclaims any intent or obligation to update these forward-looking statements.

OncoMed Has 'Wnt' in its Sails; Bayer Deal Adds $40M Up Front by Jennifer Boggs, Bioworld, June 18, 2010. Excerpts:

[OncoMed's] latest accomplishment is another early stage deal, this time with Bayer Schering Pharma AG, to develop drugs targeting the Wnt signaling pathway. It's an agreement that brings $40 million up front, with the potential for more than $1 billion in future milestones.

.....

The Wnt pathway is believed to be a key target in halting cancer stem cell activity. But only a few other firms - Avalon Pharmaceuticals Inc. (now part of Clinical Data Inc.) and 2008 start-up Wintherix LLC, for example - have entered that space, largely because Wnt is not an easily druggable target.

News release from Bayer: Bayer Schering Pharma and OncoMed Pharmaceuticals Enter Strategic Alliance to Develop Anti-Cancer Stem Cell Therapeutics, June 17, 2010. Excerpt:

Bayer Schering Pharma AG, Germany, and OncoMed Pharmaceuticals, Inc., today announced a global strategic alliance to discover, develop and commercialize novel anti-cancer stem cell therapeutics targeting the Wnt signaling pathway. Cancer stem cells are a subset of tumor cells believed to play a significant role in the establishment, metastasis and recurrence of cancer and agents targeting the Wnt pathway have the potential to be developed as pan-tumor drugs.

Comment: The Bayer-OncoMed strategic alliance has received attention via the social media. See, for example, the results of this FriendFeed search.
