The cell suspension was prepared at a final density of 6 × 104 cells/well. After washing with PBS that had been pre-cooled at 4 °C, 2 μl Annexin V-APC and PI (Thermo Fisher Scientific, USA) were added for staining for 20 min in dark, and then the extent of apoptosis was assessed by flow cytometric analysis (MilliporeSigma, USA). These experiments were performed in triplicate. Bar graphs are the mean ± SD of three separate experiments.
