Millipore’s HEScGRO Medium Advances Human Embryonic Stem Cell Research

Billerica, Massachusetts --- January 22, 2007 --- Millipore Corporation today announced the availability of HEScGRO animal component-free medium for human embryonic stem cell research. HEScGRO medium is the first commercially available animal component-free medium tested successfully for human embryonic stem cell culture and shown to maintain hES cells in their undifferentiated state. An agreement between Millipore and Stem Cell Sciences (SCS) announced in October 2006 made it possible for Millipore to manufacture and market SCS' serum-free media.

HEScGRO medium’s unique serum-free, ready-to-use and complete formulation offers new ease and reliability in growing human embryonic stem cells. Media with animal-derived components are subject to wide variability and may contain factors that promote differentiation of hES cells, as well as toxic proteins or immunogens that can adversely affect the cells themselves. HEScGRO medium is a defined, animal component-free formulation that successfully addresses these problems and allows scientists to grow human stem cells with confidence.
