Collection of morphological different CD71+(green)/CD45−(yellow)/Hoechst+(blue) erythroblast-like cells from healthy donors. Morphology and phenotype are characteristic for erythroblasts. Different stages of maturation may be indicated by the nucleus appearance under brightfield as well as high intensity Hoechst signal and the cell size. Cells (A) is the smallest and most mature measuring 8.4 µm in diameter, Cell (B) is larger and less mature measuring 11.2 µm in diameter, Cell (C) is the largest and less mature measuring 13.4 µm in diameter. White scale bar is 5 µm.
