The frequency of different cell populations within the bone marrow of 7-week old WT and OI mice was evaluated by flow cytometry (n=5–6). Data are shown for (A) Lin− Sca1+ cKit+ (LSK) hematopoietic progenitor cells; (B) common lymphoid progenitors (CLP), Lin− Sca1+ cKitint IL7R+; (C) B cells, B220+; (D) common myeloid progenitors (CMP), Lin− Sca1− cKit+ CD34+ CD16lo; (E) granulocyte macrophage progenitors (GMP), Lin− Sca1− cKit+ CD34+ CD16hi; (F) megakaryocyte erythroid progenitors (MEP), Lin− Sca1− cKit+ CD34− CD16−; (G) myeloid cells, CD11b+; (H) granulocytes, Ly6G+; and (I) erythrocyte progenitors, Ter119+. * p<0.05 compared to WT control.
