ABSTRACT
Objective To investigate the function of human glia maturation factor gamma to induce the proliferation and differentiation of neural stem cells into astrocytes.Methods The neural stem cells were isolated from cerebral cortex of 11-to 12-day embryoes of SD rats.After three passages,the cells could react with nestin antigen,which demonstrated that the cells were neural stem cells.The neural stem cells were divided into 4 groups,control group,FBS group FBS,GMFG 5 ?g/L group and 5 ?g/L of GMFG,GMFG 10 ?g/L group with medium and 10 ?g/L of GMFG.Results In the control group,the cells had no significant differentiation in two days and slight branches were observed at the fourth day.In FBS group,the cells differentiation into astrocytes within three days,which grew on the surface of the culture flasks.In GMFG group,the cells differentiated into astrocytes in one day,and the differentiation of cells from the 10 ?g/L group was more obvious than that of cells from the 5 ?g/L group.The cells from the 10 ?g/L group reacted weakly with GFAP antigen.Conclusion GMFG can induce proliferation and differentiation of neural stem cells into astrocytes effectively in vitro.
