EGCG reduces the invasion of PC-3 cells. The cell invasion assay was performed using a Transwell with a matrigel-coated membrane filter for 24 h. Cells were stained, and noninvaded cells on the upper surface of the filter were removed. (A) Images were photographed at 200× magnification. Scale bar = 100 μm. (B) The number of cells invading the lower surface of the filter was quantified. Data are expressed as means ± SD. Results were statistically calculated by Student’s t-test. *** p < 0.001 vs. untreated control; ## p < 0.01 and ### p < 0.001 vs. fetal bovine serum (FBS)-treated control.
