Transfection of bone marrow mesenchymal stem cells using green fluorescence protein labeled hVEGF165 recombinant plasmid mediated by liposome

ObjectiveTo study the role of bone marrow mesenchymal stem cells (BMSCs) in construction of vascularized engineered tissue.MethodshVEGF165 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 LipofectamineTM 2000 for packaging and amplifying. hVEGF165 mRNA expression in BMSCs cells was tested. Results: The sequence of hVEGF165 in pShuttle-GFP-hVEGF165 plasmid was confirmed by double-enzyme cleavage method and sequencing. hVEGF165 was highly expressed in BMSCs.ConclusionsThe GFP/hVEGF165 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.
