CAE increased E-cadherin and decreased N-cadherin in TGF-β1-induced A549 cells. A Immunofluorescence staining of A549 cells with antibodies against E-cadherin. B Immunofluorescence staining of A549 cells with antibodies against N-cadherin. The scale bar is 50 μm. C, D The positive staining areas were measured by Image J software (n = 3). All data were presented as means ± SEM. *P < 0.05, **P < 0.01, ***P< 0.001 vs. the TGF-β1 group, ^# P < 0.05, ^## P < 0.01, ^### P < 0.001 vs. control group
