OBJECTIVE: To study the effect of Panax notoginseng saponins (PNS) on cell proliferation, type I collagen secretion and integrin beta 1 expression in human kidney fibroblast (KFB). METHODS: KFB were cultured and stimulated by PNS in vitro. The cell proliferation, type I collagen secretion and integrin beta 1 expression in KFB were measured by methyl thiazolyl tetrazolium (MTT), enzyme-linked immunoabsorbent assay (ELISA) and flowcytometry respectively. RESULTS: Within its optimal concentration range and effective time range, PNS could obviously inhibit the proliferation, type I collagen secretion and integrin beta 1 expression (all P < 0.05) in human KFB. CONCLUSION: PNS would possibly be an effective drug for renal interstitial fibrosis prevention and treatment.
