In vitro apoptosis detection in cervical cancer HeLa cells. (A) Representative pictures (black arrows indicating morphological changes) of HeLa cells treated with 10 μM and 30 μM CDDP with/without the combination of 10 μM RDM-B (BV10) for 12 h and then incubated with the CellEvent Caspase-3/7 Green Detection Reagent and analyzed using fluorescence microscopy. (B) Percentages of activated caspases 3/7. (C)–(H) Early/late apoptosis measurements of HeLa cells treated with 20 μM and 40 μM CDDP with/without the combination of 20 μM BV10 for 18 h using an Annexin V-FITC Apoptosis Detection Kit, where the cells were double stained with Annexin-V-FITC and PI. Quantitative analyses of the cell images in A and flow cytometry data in (C)–(H) were performed using an ImageJ software (https://imagej.nih.gov/ij/) and a FlowJo software (https://www.flowjo.com/solutions/flowjo), respectively.
