Time course of erythroid differentiation by HA, radicicol, KF25706, and KF58333.
K562 cells were cultured with 0.3 μmol/L of HA, radicicol, KF25706, and 0.05 μmol/L of KF58333 for the indicated times and analyzed for differentiation as described in “Materials and methods.” Percent of GPA-positive cells (A) and percent of benzidine-positive cells (B) are indicated.
