The transcription factor Meis1 is expressed preferentially in hematopoietic stem cells (HSCs) and overexpressed in certain leukemias. However, the functions of Meis1 in hematopoiesis remain largely unknown. In the present study, we found that Meis1 is required for the maintenance of hematopoiesis under stress and over the long term, whereas steady-state hematopoiesis was sustained in the absence of Meis1 in inducible knock-out mice. BM cells of Meis1-deficient mice showed reduced colony formatio ...[more]
