Invitrogen Launches First Ever Serum Free Media for Mesenchymal Stem Cells

Company Adds New Kits to Differentiate Mesenchymal Stem Cells

CARLSBAD, Calif.–Invitrogen Corporation (NASDAQ:IVGN – News), a provider of essential life science technologies for research, production and diagnostics, announced the launch of a serum free media (SFM) designed specifically to culture mesenchymal stem cells (MSCs), or stem cells derived from bone marrow. STEMPRO® MSC SFM is a first of its kind product that overcomes many challenges in MSC culture. In concert, Invitrogen also launched two kits designed to allow the differentiation of MSCs to either adipocytes (fat cells) or osteocytes (bone cells).

MSCs are currently in use for therapeutic applications, but until now, their growth in vitro has required the use of media containing animal-derived serum. Serum-based media includes undefined elements that can make performance vary from lot to lot. In addition, the inclusion of undefined animal components can raise questions with respect to regulatory agency approval of therapeutics based on MSCs.

STEMPRO® MSC SFM is completely defined, meaning that each element is present in the media at a known quantity, thereby eliminating significant lot-to-lot variability. The media maintains MSCs in an undifferentiated state for more than nine passages whereas cells in traditional media supplemented with serum start to demonstrate diminished cellular expansion and differentiation after five passages.

“Scientists have been searching for years to develop a reliable serum free media on which to grow mesenchymal stem cells,” said Joydeep Goswami, Ph.D., vice president of stem cells and regenerative medicine for Invitrogen. “STEMPRO® MSC SFM satisfies a keen need for these researchers and will allow therapeutics companies to provide more robust products to patients who need them.”

In addition to launching STEMPRO® MSC SFM, Invitrogen launched two other products: STEMPRO® Adipogenesis and STEMPRO® Osteogenesis differentiation kits. These kits contain media and specific supplements that can induce MSCs to follow the developmental path to either bone cells or fat cells, allowing researchers to study how MSCs differentiate into multiple tissue types.
