【Abstract】 Objective To elucidate the method of culturing Bovine lens epithelial cells in vitro and the characteristics of the cells and to investigate the inhibition of γ-interferon(γ-IFN) on the proliferation of bovine lens epithelial(BLECs).Methods Primary culture and subculture of BLECs were established in vitro. γ-IFN at concentrations from 10 1U/ml-10 5U/ml were added to the epithelial cells of second passage. The inhibitive effects of γ-IFN on proliferation of BLECs were measured with methyl thiazolyl tetrazolium(MTT) assay method.Results After treatment withγ-IFN, lens epithelial cells showed marked inhibition depending on the concentration of γ-IFN from 10 3U/ml to 10 5U/ml,especially in 10 4U/ml of γ-IFN.Conclusion γ-IFN plays a significant role in inhibiting the proliferation of BLECs.更多还原
