Abstract:
Objective To explore the protective effect of HGF on primary cultured spinal neurons in vitro.Methods Cultured neurons were transfected with Ad-GFP or Ad-HGF in different multiplicity of infection(MOI),then flow cytometer and PI-Hoechst double stains were used to assay transfer rate or to determine the status of cells respectively.ELISA was used to detect the expression of HGF in Ad-HGF transfected neurons,and the activity of neurons was judged by neutral red stain,MTT and NSE-ELISA methods.Results After transfection with Ad-GFP in MOI of 50,the transfer rate was high as detected by flow cytometer,and the status of cells was well as judged by PI-Hoechst double stain.The results of ELISA showed that HGF was expressed in medium.After transfection with Ad-HGF,the activity of neurons was better than neurons without treatment(P
