Differential effects of RHAU ablation on erythroid cell differentiation in the BM and spleen. (A-B) The different developmental stages were identified by FACS with the use of Ter-119 and CD71 markers together with the forward scatter (FSC) parameter.²⁸  Ter119⁺ cells are classified into the following 4 subgroups: ProE (Ter119^med CD71^hi), Ery.A (Ter119^hiCD71^hiFSC^hi), Ery.B (Ter119^hiCD71^hiFSC^low), and Ery.C (Ter119^hiCD71^lowFSC^low). The mean proportions of each subgroup ± SEs (n = 4) are shown beside the boxes in the dot plots. (C) Effect of RHAU ablation on total numbers of erythroblasts in the BM and spleen. Cell numbers of the 4 subgroups are indicated in the bars by different colors, denoting, from the top, Pro.E, Ery.A, Ery.B, and Ery.C. *P < .05; n = 4.
