The cells (1×10
5 cells/well) were seeded on an 8×8 mm cover slip in 24-well plates, starved overnight and then treated with 3 ng/ml TGF-β2. Following 48 h of treatment, the cells were fixed with 4% paraformaldehyde for 20 min and washed 3 times with PBS. The cells were permeabilized in PBS with 0.3% Triton X-100 for 5 min. The cells were then blocked with 5% normal goat serum for 1 h. Primary rabbit anti-human α-SMA antibody (1:500,
ab5694) and rabbit anti-human E-cadherin antibody (1:1,000,
ab53226) (both from Abcam, Cambridge, MA, USA) were incubated with the cells overnight at 4°C. After being rinsed extensively, the cells were exposed to the fluorescent secondary antibody (goat anti-rabbit Cy3, 1:10,000,
CW0114S; goat anti-rabbit FITC, 1:10,000,
CW0159S; both from CWBIO, Beijing, China) in the dark for 30 min. The coverslips were rinsed again with PBS 3 times and mounted with DAPI for 5 min, as a nuclear counterstain. Finally, the cells were observed under a fluorescence microscope (DP71; Olympus, Tokyo, Japan).
