Abstract

We propose a novel method for the efficient production of hematopoietic progenitors from human embryonic stem cells (hESC) via coculture with murine fetal liver-derived stromal cells, in which embryonic hematopoiesis dramatically expands at midgestation. We generated various hematopoietic progenitors in coculture, and this hematopoietic activity was concentrated in cobblestone-like cells derived from differentiated hESC. The cobblestone-like cells mostly expressed CD34 and retained an endothelial cell potential. They also contained hematopoietic colony-forming cells, especially erythroid and multilineage colony-forming cells at high frequency. The multipotential hematopoietic progenitors abundant among the cobblestone-like cells produced almost all types of mature blood cells, including adult-type β-globin-expressing erythrocytes and tryptase/chymase double-positive mast cells. These progenitors showed neither the immature properties of ESC nor the potential to differentiate into endoderm and ectoderm at a clonal level. The coculture system developed for hESC can provide a novel source of hematopoietic and blood cells for applications in cellular therapy and drug screening.
