Objective · To clarify effect of adipose stem cells derived conditioned medium (ASCs-CM) on fibrogenesis of dermal fibroblasts co-stimulated by transforming growth factor-β1 (TGF-β1), and explore the possible paracrine pathway of ASCs in regulating the dermal tissue rehabilitation. Methods · Co-stimulated by TGF-β1, dermal fibroblasts were treated with different concentrations of ASCs-CM. Various cellular events including cell proliferation, apoptosis, and mRNA and (or) protein levels of α-smooth muscle actin (α-SMA), type Ⅰ collagen (COL-1) , type Ⅲ collagen (COL-3), hepatocyte growth factor (HGF), basic fibroblast growth factor (FGF-2) were explored. Furthermore, the effect of HGF antibody on apoptosis of fibroblasts caused by ASCs-CM and TGF-β1 were also observed. Results · ASCs-CM inhibited fibroblasts proliferation caused by TGF-β1 and lead to cell apoptosis. α-SMA expression in fibroblasts was attenuated by 10% ASCs-CM +TGF-β1. It was demonstrated that 100% ASCs-CM with TGF-β1 had promoted collagens (especially COL-3) expression in fibroblasts, and increased HGF mRNA level as well. HGF antibody inhibited fibroblasts apoptosis produced by 100% ASCs-CM and TGF-β1. Conclusion · ASCs may have an effect on fibrogenesis of dermal fibroblasts co-stimulated by TGF-β1 through a paracrine way. High concentration of ASCs-CM not only increases collagen production and secretion, but also inhibits fibroblasts proliferation and accelerates apoptosis.
