Further, STAT3 regulates IL-6–mediated and TGF-β1–mediated myofibroblast differentiation in murine lung fibroblasts [30], and inhibition of STAT3 was found to reduce TGFβ1-induced FMT in fibroblasts, and ameliorate skin fibrosis in two mouse models of systemic sclerosis [82]. This evidence concerns the gene TGFB1 and systemic sclerosis.
