ST. LOUIS, Oct. 3, 2012 /PRNewswire/    --Sigma-Aldrich Corporation (SIAL)    announced today that Sigma Life Science, its innovative    biological products and services research business, has    launched Stemline Pluripotent Culture Medium, a    novel human pluripotent stem cell culture medium that provides    a consistent environment for the long-term maintenance and    growth of healthy pluripotent stem cells. The new medium    performs equivalently to the industry's leading medium and    provides academic and pharmaceutical stem cell research labs    with a substantially lower cost alternative to higher priced    media. Additional information and sample requests of the    Stemline Pluripotent Culture Medium are available at http://www.sigma.com/stemlinepsc.  
    "The exorbitant cost of media for pluripotent stem cells is a    universal complaint from the stem cell research community. Our    Stemline Pluripotent Culture Medium performs equivalently to    the leading medium for maintaining pluripotency and optimal    growth rates, and is produced more efficiently than traditional    media, resulting in lower costs. For example, a typical    academic lab that consumes three 500 mL bottles of media per    week could save at least $12,000 annually using our new    Stemline medium. A high-throughput pharmaceutical development    team that consumes 20 liters of media weekly could save more    than $160,000 annually," said John Listello, Market Segment    Manager for Regenerative Medicine at Sigma Life Science.  
    Culturing pluripotent stem cells can be challenging as many    media's undefined, heterogenous mixtures can cause inconsistent    growth rates and undesired spontaneous differentiation. The    Stemline Pluripotent Stem Cell Culture Medium is serum-free,    composed of fully-defined components and has 80% less basic    fibroblast growth factor than the leading pluripotent stem cell    culture medium. This provides a consistent environment for    long-term maintenance of optimal growth rates, viability and    pluripotency. Rigorous characterization of the Stemline    Pluripotent Stem Cell Culture Medium has demonstrated that    cultured pluripotent stem cells display all established    pluripotency markers and maintain proper karyotype and the    ability to differentiate into each of the three germ layers.    The feeder-independent medium also enables culturing with    synthetic matricies, thereby eliminating a source of    variability that would prohibit later clinical applications.  
    "Academic and pharmaceutical groups performing toxicology    screens, disease-specific stem cell research or studies of the    basic mechanisms behind pluripotency and differentiation depend    upon a steady supply of consistent, high-performance cell    culture medium. This novel Stemline medium extends Sigma's    existing position as one of the largest global providers of    cell culture media," said Listello.  
    Existing Stemline stem cell culture media include specialized    formulations for expansion of six human adult stem cell and    progenitor cell types: hematopoietic, neural, dendritic,    mesenchymal, T-cells, and keratinocytes. These six Stemline    media are produced under good manufacturing practices (GMP) and    have Device Master File certificates from the U.S. Food and    Drug Administration.  
    Sigma Life Science's comprehensive stem cell product portfolio    includes custom iPS cell CompoZr ZFN-mediated    genetic engineering, Stemgent Reprogramming    Lentiviruses, the MISSION shRNA Library with the    latest content release from The RNAi Consortium, 3D matrices,    growth factors, small molecules, other cell culture media and    the industry's most validated antibodies. Sigma Life Science    acquired a worldwide license to Kyoto University's iPS cell    patent portfolio in February, 2012.
