TGF-β2 group cells compared to control group cells. Phase-contrast micrographs were used to observe cells in the control group (a) and TGF-β2 group (b). The single polygonal cells changed into long, spindle-shaped cells. c Total RNAs were extracted from the control group(n = 3) and TGF-β2 group(n = 3), qRT-PCRs were conducted to detect the expression of E-cadherin, α-SMA, and vimentin(*P < 0.05, **P < 0.01). d The proteins were collected from the control group(n = 3) and TGF-β2 group(n = 3), western blot was conducted to detect the expression of E-cadherin, α-SMA, and vimentin. e The expression of E-cadherin, α-SMA, and vimentin were detected by immunofluorescence
