DNA cell cycle kinetics and morphologic changes during terminal erythroid differentiation.
FVA erythroblasts were cultured for 0 (A, D), 24 (B, E), or 48 (C, F) hours with EPO. Cells were removed from culture and analyzed for DNA cell cycle analysis of PI-stained cells by flow cytometry (A, B, C) or benzidine staining (D, E, F). Percentages of cells in G1 at 0, 24, and 48 hours of culture were 32%, 49%, and 84%, respectively.
