Flow cytometry analysis for apoptosis-inducing activities of colchicine and luteolin in Mgc-803 cells. The appearance of apoptosis cells was detected by flow cytometry using Annexin V/PI staining. A–C: Negative control. D–I: Positive control; treatment with HCPT and VP-16 (20 μM) for 12, 24, and 36 h. J–R: Treatment with luteolin (5, 10, and 20 μM) for 12, 24, and 36 h. S–A: Treatment with colchicine (5, 10, and 20 μM) for 12, 24, and 36 h.
