Impaired BaPs in Runx1P1N/P1N mice. (A-C) Representative flow cytometry plots and percentage of indicated gates of SN-Flk2+ (Sca-1−Lin−c-Kit+CD150−Flk2+CD27+) cells and SN-Flk2− (Sca-1−Lin−c-Kit+CD150−Flk2− CD27+) cells (A), and BaPs (Lin−CD34+c-Kit−FcϵRIα+) in BM from WT or Runx1P1N/P1N mice (B), and BMCPs (Lin−c-Kit+β7+FcγRII/III+) in spleen from WT or Runx1P1N/P1N mice (C). Data shown are from 1 of 3 independent experiments, each of which gave similar results.
