Megakaryocytic-Erythroid Progenitors (MEP) produce circulating red blood cells and platelets. Although much is known regarding megakaryocytic (Mk) and erythroid (E) maturation, detailed molecular mechanisms underlying the MEP fate decision have not been determined. Single cell RNA sequencing of highly enriched populations of primary human common myeloid progenitors (CMP), MEP, megakaryocyte progenitors (MKP) and erythroid progenitors (ERP), revealed that MEP have a distinct molecular signature with co-expression of genes otherwise expressed exclusively in CMP, MKP or ERP. Cell cycle genes are significantly differentially expressed between MEP, MKP, and ERP. We therefore tested the effects on MEP fate of genetic and pharmacologic modulation of cell cycle progression, and found that cell cycle activity mechanistically controls MEP fate decisions; cell cycle activation promotes E whereas cell cycle inhibition promotes Mk specification. The data obtained from healthy cells can now be applied to the mechanisms underlying benign and malignant disease states of Mk and E production. SOURCE: Yi-Chien LuKrause Lab Yale Medical School
