StemSpan™ Serum-Free Expansion Medium II (SFEM II) is a modified version of StemSpan™ SFEM. It has been developed for the in vitro culture and expansion of human hematopoietic cells, when the appropriate growth factors and supplements are added. This allows users the flexibility to prepare the medium to meet their requirements. Using appropriate StemSpan™ Expansion Supplements, SFEM II may be used to expand CD34+ cells isolated from human cord blood, mobilized peripheral blood or bone marrow samples, or to expand and differentiate lineage-committed progenitors to generate populations of erythroid, myeloid, or megakaryocyte progenitor cells.
