Global loss of microRNA-146a (miR-146a) inhibits bone marrow (BM) hematopoiesis and promotes extramedullary hematopoiesis in the spleen. Increase of splenic (A) and decrease in BM (B) CD45+ leukocytes and Ly6G/CD115 lymphocytes in DKO mice on diet for 18 wk, determined by fluorescence-activated cell sorting (FACS) analysis (n=5). C, Decrease of multipotent progenitor cells (MPPs) and downstream progenitor cells (eg, Sca-1 [stem cells antigen-1]–negative progenitor [LSK], megakaryocyte–erythroid progenitor [MEP], common myeloid progenitor [CMP], and granulocyte–macrophage progenitor [GMP]) in BM of double knockout (DKO) mice after 18 wk of high cholesterol diet (HCD; n=5). D, Increase of splenic hematopoietic and multipotent stem cells in DKO mice after 18 wk of HCD (n=5; Online Figure VII). HPC indicates hematopoietic progenitors cell; HSC, hematopoietic stem cell; Ldlr, low-density lipoprotein receptor; and LSK, lineage- Sca-1+ Kit+.
