Analyses of cell viability and cell size during the induction of differentiation of the established erythroid progenitor cell lines.

<p>Cell viability and cell size were estimated by an automated cell counter. (A) Results of HiDEP-1 cells. (B) Results of HUDEP-1 cells. (A, B) <10 µm (%), the percentages of cells with a diameter less than 10 µm. Among all HiDEP and HUDEP cell lines, HiDEP-1 cells most efficiently differentiated into more mature cells.
