TGF-β induced EMT in HepG2 cells. a Changes of cell morphology were assessed following treatment of HepG2 cells with various concentrations (0.1–10 ng/mL) of TGF-β for 24 h. The magnification is 100 times. b The expressions of E-cadherin and Vimentin were determined with immunofluorescence method in HepG2 cells treated with TGF-β (5 ng/mL) for 24 h. The magnification is ×400. c The expressions of E-cadherin, and Vimentin were measured with western blot analysis in HepG2 cells treated with various concentrations (0.1–10 ng/mL) TGF-β for 24 h
