With the development of cancer stem cell niche theory, it gradually becomes a new hotspot and target on treatment of gliomas. So gene therapy based on the vector of oncolytic virus (VAE) shows a great advantage. Th is method focues on the advantage of gene therapy and virus therapy is a new treatment to gliomas. To explore whether VAE can infect and kill glioma stem cells (GSCs), meanwhile the expression of exogenous Endo-Angio fusion gene carried by VAE can inhibit GSCs? vascular niche in vitro, we have collected surgical specimens of human high grade glioma (WHO class III, VI), and GSCs were isolated under the culture conditions originally designed for selective expansion of neural stem cells. Aft er that we achieved the following results: (1) 4 cases of GSCs isolated from 20 surgical specimens could suspend growth and had the ability of self-renewal and multipotential diff erentiation; could express neural stem cells marker, CD133 and Nestin. (2) VAE could infect GSCs and signifi cantly inhibit the viability of GSCs ( P<0.05 ); ( 3 ) Signifi cant expression of Endo-Angio fusion gene was observed aft er GSCs were infected by VAE 48 hours and it could inhibit human brain microvascular endothelial cells ( HBMEC ) proliferation(P<0.05); (4) Residual viable cells lose the ability of self-renewal and adherent diff erentiation. In Conclusion, VAE can signifi cantly inhibit the activity of GSCs in vitro and the expression of exogenous Endo-Angio fusion gene can inhibit HBMEC proliferation. VAE can be used as a novel virus-gene therapy strategy for gliomas.
