Expansion of early progenitors in Fog^ki/ki BM. Total BM from WT and Fog^ki/ki mice at 5 to 7 weeks of age. (A) LSK cells from BM were identified via flow cytometry. LK myeloid progenitors were divided into CMP, GMP, and MEP using CD34 and FcγR II/III. (B) The proportions of LSK, CMP, GMP, and MEP were calculated for the BM (n = 10). Errors bars represent SEM. *P < .05, **P < .01 by Student t test.
