The mechanisms which regulate HSC regeneration following myelosuppressive injury are not well understood. We identified epidermal growth factor (EGF) to be highly enriched in the bone marrow (BM) serum of mice bearing deletion of Bak and Bax in Tie2 + cells (Tie2Cre;Bak1 −/− ;Bax fl/− mice), which displayed radioprotection of the HSC pool and 100% survival(More)
Hematopoietic stem cell (HSC) self-renewal, proliferation and differentiation are regulated by signaling through protein tyrosine kinases (PTK) such as c-kit, Flt-3 and Tie2. PTKs work in concert with receptor protein tyrosine phosphatases (PTPs) to maintain cellular equilibrium. The functions of PTPs in counterbalancing PTK signaling in HSCs however remain(More)
