Annexin V and Ki67 expression analysis by flow cytometry. T47D cells were serum-starved for 24 h and treated with R5020 ± TPA for 24, 48 and 72 h. The percent of cells expressing each of the proteins was determined using flow cytometry. a. Annexin V. b. Ki67. Vehicle-treated cells were used as a control. * represents p value <0.05. h = hours
