Expansion and differentiation of cRBCs. (A) Amplification of human CD34⁺ cells obtained by G-CSF–mobilized LK. Results are expressed as the mean ± SD (n = 9). (B) NMB staining from cRBC and (C) from native reticulocytes (original magnification ×50). (D) Flow cytometric analysis of one representative experiment from 9 independent experiences: expression of glycophorin A-PE, CD71-PE, and CD36-FITC from cRBC and (E) from native reticulocytes. Solid histograms represent relevant mAbs and open ones negative controls with irrelevant mAbs.
