Abstract

Aim: To explore the effect of ciliary neurotrophic factor (CNTF) on retinal ganglion cell (RGC)-5 induced by hydrogen peroxide (HO).

Methods: After cell adherence, RGC-5 culture medium was changed to contain different concentrations of HO from 50 to 150 µmol/L at four time points (0.5, 1, 1.5 and 2h) to select the concentration and time point for HO induced model. Two different ways of interventions for injured RGC-5 cells respectively were CNTF as an addition in the culture medium or recombinant lentiviral plasmid carrying CNTF gene transfecting bone mesenchymal stem cells (BMSCs) for co-culture with RGC-5.

Results: Compared to the control group, HO led to RGC-5 death closely associated with concentrations and action time of HO and we chose 125 µmol/L and 2h to establish the HO-induced model. While CNTF inhibited the loss of RGC-5 cells obviously with a dose-dependent survival rate. Nevertheless two administration routes had different survival rate yet higher rate in recombinant lentiviral plasmid group but there were no statistically significant differences.

Conclusion: Both the two administration routes of CNTF have effects on RGC-5 cells induced by HO. If their own advantages were combined, there may be a better administration route.
