Evidence of anticancer drug‐induced apoptosis in cancer cells. Cells were treated with three doses of each anticancer drug for 24 h, respectively, and the percentage of TUNEL positive cells was determined. 1, cisplatin (CP); 2, mechlorethamine (MCH); 3, Mitomycin; 4, Etopside; 5, Doxorubicin; 6, methotrexate (MTX); 7, Taxol; 8, Vincristine; 9, epigallocatechin gallate (EGCG). Less than 1% TUNEL positive cells was observed in the untreated samples. Note that increased percentage of TUNEL positive cells is associated with increased drug concentration.
