title: Development of hematopoietic cells from embryonic stem cells.
abstract: Embryonic stem cells are pluripotent stem cells that can differentiate into all somatic cell lineages and germ lineage cells in vivo. In vitro differentiation capacity of the cells is rather limited compared with the in vivo pluripotency. However, differentiation into hematopoietic lineages is easily obtained, and it is a powerful tool to investigate hematopoietic development and differentiation. In this article, we describe a differentiation induction method that we established, the OP9 system, a unique method using the macrophage colony-stimulating factor-deficient stromal cell line OP9. The utility of the OP9 system includes hematopoietic development, differentiation, B-cell formation, osteoclast formation, and so on. The usefulness and limits of embryonic stem cell-derived hematopoietic cells in cell therapy are also discussed.
