We have recently demonstrated through a chemical screen in the zebrafish embryo that prostaglandin E2 (PGE2) is an evolutionarily conserved regulator of hematopoietic stem cell (HSC) number. These results have further been confirmed by in vitro and in vivo studies in the murine model. Bioactive PGE2 derivatives have potential clinical application to accelerate recovery of the hematopoietic system following chemotherapy or irradiation. Ex vivo expansion of HSCs prior to stem cell transplantation may improve reconstitution of hematopoiesis and immune function. This article aims to summarize current knowledge of PGE2-mediated regulation of blood cell homeostasis as well as to discuss the proposed use of PGE2 to expand hematopoietic stem cells for transplantation in the clinical setting.
