Effects of MVs or Smad7-MVs treatment on the changes of pathology in the TA of rats. 50 µL TGF-β1 (0.5 µg) were injected into the right midshaft dorsomedial TA. After injection one day, the TA was injected with 50 µL (50 µg) MVs or Smad7-MVs. The changes of pathology of TA were observed using H&E (A) and Masson (B). Scale = 100 μm. Black arrow: inflammatory factor. ^*p < 0.05, ^**p < 0.01
