Objective To investigate the effects of TGF- β1 on proliferation and type N collagen mRNAexpression of rat renal interstitial libroblasts in vitro for elucidating the role of fibroblasts in renal interstitialfibrosis. Methods The cells were cultured in media containing various concentrations of TGF- β1. Theproliferation and the type Ⅲ collagen mRNA expression of the cells were assayed with MTT method andRT- PCR respectively. Results TGF- β1, has a stimulating proliferation effect with dose- dependence and aincreasing expression of type Ⅲ collagen mRNA with both dose- and time- dependence to the renal fibroblasts. Conclusion It is suggested that TGF- β, is involved in proliferation of renal fibroblasts and their type Ⅲcollagen mRNA expression, and may play an important role in renal interstitial fibrosis.
