Abstract

Hematopoietic stem and progenitor cells (HSPCs) represent the lifelong source of all blood cells and continuously regenerate the hematopoietic system through differentiation and self-renewal. The process of differentiation is initiated in the G phase of the cell cycle, when stem cells leave their quiescent state. During G, the anaphase-promoting complex or cyclosome associated with the coactivator Cdh1 is highly active and marks proteins for proteasomal degradation to regulate cell proliferation. Following Cdh1 knockdown in HSPCs, we analyzed human and mouse hematopoiesis in vitro and in vivo in competitive transplantation assays. We found that Cdh1 is highly expressed in human CD34 HSPCs and downregulated in differentiated subsets; whereas, loss of Cdh1 restricts myeloid differentiation, supports B cell development and preserves immature short-term HSPCs without affecting proliferation or viability. Our data highlight a role of Cdh1 as a regulator of balancing the maintenance of HSPCs and differentiation into mature blood cells.
