| Research Abstract |
We established cytokine induced skin fibrosis model. We injected TGF-β first which induces skin fibrosis and CTGF next which maintain skin fibrosis. In this study, we tried to clarify the detailed mechanism of this fibrosis model using in vitro study culture systems.
(1) TGF-β alone induced collagen m-RNA.
(2) CTGF alone had no effect.
(3) TGF-β plus CTGF induced collagen m-RNA more than TGF-β alone.
(4) TGF-β suppressed c-myc-mRNA in normal fibroblasts.
(5) In scleroderma fibroblasts c-myc-mRNA was enhanced by TGF-β plus CTGF stimulation.
Thus, abnormal response to scleroderma fibroblast may contribute to skin fibrosis in scleroderma.
