Down-regulation of Mpl marks the transition to lymphoid-primed multipotent progenitors with gradual loss of granulocyte-monocyte potential.
Evidence for a novel route of adult hematopoietic stem-cell lineage commitment through Lin-Sca-1+Kit+Flt3hi (LSKFlt3hi) lymphoid-primed multipotent progenitors (LMPPs) with granulocyte/monocyte (GM) and lymphoid but little or no megakaryocyte/erythroid (MkE) potential was recently challenged, as LSKFlt3hi cells were reported to possess MkE potential. Herein, residual (1%-2%) MkE potential segregated almost entirely with LSKFlt3hi cells expressing the thrombopoietin receptor (Mpl), whereas LSK...Expand abstract
