Pirfenidone(PFD) treatment significantly (P < .05) decreased mRNA expression of collagen type I, significantly increased mRNA expression of TGF-β1 and HAS2, and significantly suppressed collagen gel contraction. However, it did not have a significant effect on the expression of αSMA. The expression of p-Smad2/3 in the nucleus was faded with PFD, possibly demonstrating the suppression of translocation of p-Smad2/3 from cytoplasm to nucleus with PFD. In conclusion, this is the first report to demonstrate the in vitro antifibrotic effects of PFD on fibroblasts isolated from scarred VFs of ferrets.
