Generate functional hematopoietic progenitor cells from human embryonic stem (ES) and induced pluripotent stem (iPS) cells with STEMdiff™ Hematopoietic Kit. Using a simple and reproducible protocol in serum- and feeder-free conditions, you can produce hematopoietic progenitor cells expressing CD34, CD45, and CD43. The robust, two-stage protocol initially induces cells toward the mesoderm before further differentiating them into hematopoietic progenitor cells. After 12 days, a population of hematopoietic cells containing 25 - 65% (average 43%) CD34+CD45+ progenitor cells can be harvested, including progenitor cells that have the capacity to form functional hematopoietic colonies in the colony-forming unit (CFU) assay. STEMdiff™ Hematopoietic Kit has been optimized for differentiation of human pluripotent cells maintained in:• mTeSR™1 (Catalog #85850)• mTeSR™ Plus (Catalog #100-0276)• TeSR™-E8™ (Catalog #05990)
