Research Abstract	We tried to induce hematopoietic cells from human pluripotent stem cells(ES cells and iPS cells) using non-feeder culture system. Our differentiation methods consist of two steps with initial sphere formation followed by secondary adherent culture. We succeeded in efficient production of neutrophils by low cell density culture, serum-free culture for hematopoietic induction, multilineage hematopoiesis with concomitant erythroid induction, production of virus-free safe human iPS cells, and hematopoietic induction from human iPS cells derived from hematopoietic progenitor cells.
