WebThe hematopoietic system, which comprises all the cellular components of the blood, is one of the earliest organ systems to evolve during embryo development. Hematopoietic stem cells (HSCs), which are rare blood cells residing in the bone marrow of the adult organism, are the founder cells that give rise to the entire hematopoietic system. Webing of mTOR in embryonic stem cells results in early embry-onic lethality,9tissue-specific gene knockout mouse model of mTOR has recently been generated.10 In the present studies, we have examined the physiological roles of mTOR in hematopoiesis and hematopoietic stem cell (HSC) function by using a hematopoietic-specific inducible …
