EGCG increases the apoptosis and decreases the viability of bladder cancer cells. The results of the apoptosis assay of the (A) PBS-treated control, (B) 10 µm EGCG and (C) 20 µm EGCG groups demonstrated increased apoptosis in the EGCG treated cells. (D) The cell viability assay revealed that 20 µm EGCG significantly inhibited bladder cancer cell growth. **P<0.01 vs. the PBS control group. EGCG, epigallocatechin gallate; NS, no significance; FITC, fluorescein isothiocyanate; PI, propidium iodide.
