Objective:To study the role of bone marrow mesenchymal stem cells(BMSCs)in construction of vascularized engineered tissue.Methods:hVEGF165 was amplified via RT-PCR before recombinant with pShuttle-green fluorescence protein;green fluorescent protein(GFP)-CMV.Then the recombinant shuttle plasmid was transfected into BMSCs with Lipofectamine~(TM)2000 for packaging and amplifying.hVTGF165 mRNA expression in BMSCs cells was tested.Results:The sequence of hVEGFI65 in pShutlle-GFP-hVFGF165 plasmid was confirimed by double-enzyme cleavage method and sequencing.hVECF165 was highly expressed in BMSCs.Conclusions:The GFP/hVECF165 recombinant plasmid vector was constructed successfully and expressed effectively in host cells,which may be helpful for discussing the possibility of the application of VEGF165-BMSCs in tissue engineering and ischemic disease cure.
