Endogenous prostaglandin E2 (PGE2) is a potent regulator of haematopoietic stem cell (HSC) retention in the bone marrow; inhibition of endogenous PGE2 signalling by non-steroidal anti-inflammatory drugs results in enhanced HSC and haematopoietic progenitor cell mobility via E-prostanoid 4 (EP4) receptor antagonism.
