Hemopoietic characterization of E14.5 dpc Baf250aE2E3/E2E3 FL cell populations. (A) Total number of FL cells (left) and number of myeloid clonogenic progenitors (right) in FL. (B) Frequency of distribution of different myeloid progenitors in FL. (C) The frequency of HSCs in E14.5 FL (left) as defined by the CD150+Ly6A/E+CD48−Lin− phenotype. The total number of HSCs in E14.5 FL (right). The HSC numbers were calculated from total mononuclear cell numbers and the HSC frequency determined for each FL population. Shown are mean (± SD). Genotypes of the examined FL populations are shown at with image. Mix indicates CFU-granulocyte, erythrocyte, monocyte/macrophage, megakaryocyte; E, CFU-erythroid; M, CFU-monocyte/macrophage; G, CFU-granulocyte; and GM, CFU-granulocyte-monocyte/macrophage.
