Expression data from control and Pbx1-null CMPs and GMPs

ABSTRACT: The capacity of the hematopoietic system to promptly respond to peripheral demands relies on adequate pools of progenitors able to transiently proliferate and differentiate in a regulated manner. However, little is known about factors that may restrain progenitor maturation to maintain their reservoirs. In addition to a profound defect in hematopoietic stem cell (HSC) self-renewal, conditional knockout mice for the Pbx1 proto-oncogene have a significant reduction in lineage-restricted progenitors, including common myeloid progenitors (CMPs) and, to a lesser extent, granulocyte-monocyte progenitors (GMPs). Through analysis of purified progenitor proliferation, differentiation capacity and transcriptional profiling, we demonstrate that in the absence of Pbx1 the CMP pool is reduced due to
