Representative flow cytometry analysis data from Annexin V-FITC staining. The histogram shows a comparison of the distribution of negative annexin V cells (M1) and positive annexin V cells (M2) after 24 hr incubation in HL-60 cells. A = control; B =6 μg/mL ATO; C = 0.5 μM VitD3 + 6 μg/mL ATO; D = 1.0 μM VitD3 + 6 μg/mL ATO; E = 1.5 μM VitD3 6 μg/mL ATO.
