Fig. 3. PD inhibits EMT in pulmonary fibrosis. HLF-1 cells were treated with DMSO, TGF-β, TGF-β + PD 50 μM, TGF-β + PD 150 μM respectively. (A) The toxicological properties of polydatin was detected by CCK-8 assay. (B and C) Cell migration ability was detected by wound healing assay. (D–F) Relative protein level of E-cadherin and fibronectin was detected by western blot. All data were represented as the mean ± SD from three independent experiments. **P < 0.01 compared with control group, #P < 0.05, ##P < 0.01 compared with TGF-β group.
