Definitive Hematopoietic Multipotent Progenitor Cells Are Transiently Generated From Hemogenic Endothelial Cells in Human Pluripotent Stem Cells.

ABSTRACT: Generation of fully functional hematopoietic multipotent progenitor (MPP) cells from human pluripotent stem cells (hPSCs) has a great therapeutic potential to provide an unlimited cell source for treatment of hematological disorders. We previously demonstrated that CD34(+) CD31(+) CD144(+) population derived from hPSCs contain hemato-endothelial progenitors (HEPs) that give rise to hematopoietic and endothelial cells. Here, we report a differentiation system to generate definitive hematopoietic MPP cells from HEPs via endothelial monolayer. In the presence of angiogenic factors, HEPs formed an endothelial monolayer, from which hematopoietic clusters emerged through the process of endothelial-to-hematopoietic transition (EHT). EHT was significantly enhanced by hematopoietic growth factors.
