Flow cytometric analysis and isolation of erythroblasts of wild-type mice bone marrow cells. (A) Plot of FSC versus SSC of all the cells. (B) Plot of 7AAD versus SSC of all the cells. (C) Plot of CD45CD11bGR1 versus SSC of all the cells. (D) Histogram of TER119 of CD45−CD11b−GR1− cells. (E) Plot of CD44 versus TER119 of the TER119 positive cells without gating. (F) Plot of CD44 versus TER119 of the TER119 positive cells with the gating on CD44hiTERlow population I. (G) Plot of CD44 versus FSC of the TER119 positive cells, showing naturally occurring clusters. (H) Plot of CD44 versus FSC of the TER119 positive cells with gating the population II, III, IV, V and VI. (I) Representative cytospin images of the sorted populations. (J) Histogram of FSC of distinct stage of erythroblasts. (K) Proportion of distinct stage of erythroblasts in bone marrow.
