Figure 7. TGF-β isoforms do not induce invasive behavior in DU145 cells.
Invasive properties of DU145 cells treated with TGF-β1 (5ng/ml), TGF-β3 (5ng/ml), or EGF (10ng/ml) were determined by an invasion assay. Cells were allowed to invade through a Matrigel coated porous membrane for 48 hours. Each bar represents mean ± SEM (n=3). *Significantly different (P < 0.05) compared with untreated controls.
