1. A method of expanding ex vivo human hematopoietic stem and/or progenitor cells, the method comprising:
a) stimulating a starting population of human stem and/or progenitor cells with a cell expanding factor selected from UM171 or analogues thereof, UM171 and UM729, or UM171 and lenalidomide, wherein the expression of Endothelial Protein C Receptor (EPCR) is increased in said stimulated starting population of stem and/or progenitor cells;
b) selecting a population of EPCR+ cells from the stimulated starting population of stem and/or progenitor cells; and
c) culturing the selected EPCR+ cells thereby expanding said EPCR+ cells.
