December 03, 2012 -- STEMCELL Technologies Inc. announced this week the launch of StemSpan™ SFEM II, a new hematopoietic stem cell expansion medium for maximum expansion of CD34+ cells from human cord blood and bone marrow. StemSpan™ SFEM II provides on average 40% higher expansion of hematopoietic progenitors compared to six leading commercially available serum-free media from different suppliers. The unparalleled performance of StemSpan™ SFEM II allows researchers to expand precious human samples and generate large numbers of primitive hematopoietic progenitors for further research applications.

“StemSpan™ SFEM II supports equivalent total nucleated cell expansion, and superior CD34+ cell expansion, compared to the existing highest performance serum-free media on the market,” said Dr. Bert Wognum, the senior scientist responsible for hematopoietic stem cell expansion medium development at STEMCELL Technologies. “It also supports erythroid and megakaryocyte expansion and may be used by researchers to develop and optimize their own culture systems to generate large numbers of other mature blood cells.”

“We are delighted to support hematopoietic stem cell researchers by providing StemSpan™ SFEM II, allowing them increased flexibility of experimental design for applications requiring large numbers of hematopoietic progenitors” said Dr. Allen Eaves, CEO and President of STEMCELL Technologies.

The high-quality StemSpan™ serum-free media products include StemSpan™ SFEM, StemSpan™ SFEM II, StemSpan™ H3000 and StemSpan™ ACF for ex vivo expansion of hematopoietic progenitor cells.
