PALO ALTO, Calif., March 29, 2011 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM) announced today the launch of three new cell culture supplements for the derivation, culture and differentiation of human and mouse embryonic stem (ES) cells, induced pluripotent stem (iPS) cells, and tissue-derived neural stem (NS) cells. 1-13 The research community demands reliable and cost-effective options for the reagents they routinely use to capture, define and instruct stem cell behavior. These new supplements satisfy this demand by providing researchers with additional choices to use either a defined, serum-free, or a defined, serum-free and animal component-free (AF) version of culture supplements that are considered to be fundamental reagents for stem cell research. "We are pleased to continue growing and diversifying our SC Proven ® reagents business to meet the needs of the burgeoning stem cell research market," said Stewart Craig, Ph.D., Senior Vice President, Development and Operations at StemCells, Inc. "In 2010, SC Proven product sales revenue grew by approximately 30%, and we are continuing to experience double digit growth this year. "Our expanding line of SC Proven cell culture supplements provides researchers with well-defined reagents that are free of the serum and animal protein-derived contaminants that can cause variability of performance and impair analyses, particularly in the context of stem cell-based drug screens," continued Dr. Craig. "Furthermore, the use of animal component-free formulations is an important consideration for researchers considering bench-to-bedside applications in which human stem cell lines may be derived, expanded and banked for potential future translation into clinical trials." NDiff ® N2-AF is a proprietary, defined, serum-free and animal component-free version of the Company's NDiff N2 product, a proprietary, defined, serum-free cell culture supplement based on the original Bottenstein formulation. 1 NDiff N27 is a proprietary, defined, serum-free cell culture supplement based on the original Brewer formulation. 2 NDiff N27-AF is a proprietary, defined, serum-free and animal component-free version of NDiff N27.
