ATG inhibits the transformation of fibroblasts into myofibroblasts in vivo. (A) Representative fluorescence images of skin sections stained against α-SMA (green) to identify myofibroblasts. Nuclei were counterstained with DAPI (blue). Scale bar, 30 µm; magnification, ×200. (B) α-SMA mRNA expression levels were measured via reverse transcription-quantitative PCR. (C) α-SMA protein expression levels were measured via western blotting. **P<0.01. ATG, arctigenin; α-SMA, α-smooth muscle actin; BLM, bleomycin; Con, control.
