HCPT-EVs showed an enhanced inhibitory effect on myofibroblast activation induced by TGF-β1. Rat fibroblasts were incubated with Unprimed EVs or HCPT-EVs (100 μg/mL) in the presence of TGF-β1 (2 ng/ml) for 24 or 48 h. a, b Immunofluorescent staining of COL III and α-SMA. c WB analysis of COL III and α-SMA. d, f Semiquantitative analysis of WB results. e, g qRT-PCR analysis of COL III and α-SMA expression. *P < 0.05, **P < 0.01, ***P < 0.001; ns, not significant
