Morphological changes during luteolin and colchicine-induced apoptosis in Mgc-803 cells detected by TUNEL staining. After treatment with colchicine and luteolin at 20 μM, Mgc-803 cells were stained with TUNEL and observed under light microscopy. A: Negative control (without treatment). B, C: Positive control; treatment with VP-16 and HCPT (20 μM) for 24 h. D: Treatment with colchicine (20 μM) for 24 h. E: Treatment with luteolin (20 μM) for 24 h.
