Fig. 3.
The percentage of apoptotic APL cells after As2O3 treatment. (A) Primary APL cells were incubated with different concentrations of As2O3 for 3 and 6 days; (B) NB4 cells and MR2 cells were incubated with As2O3 (1.0 μmol/L) and ATRA (0.1 μmol/L) for 1, 3, and 5 days. The percentage of apoptotic cells or sub-G1 cells was analyzed by flow cytometer.
