The expression of E-cadherin, vimentin, α-SMA protein during the development of early pulmonary fibrosis. The expression of E-cadherin, vimentin and α-SMA protein in lung tissue in an animal model of early pulmonary fibrosis was detected by western blotting (a) and immunofluorescence (b). All data are expressed as the mean±s.d. from at least three replicate experiments. *P<0.05 and **P<0.01 vs the control group.
