Human vascular endothelial growth factor cDNA cloning and expression in osteoblasts
Human vascular endothelial growth factor (VEGF) cDNA was amplified by nested polymerase chain reaction method from the HL60 cells. Then a pCD-hVEGF165 recombinant plasmid was constructed. Rabbit osteoblasts were transfected with pCD-hVEGF165 plasmid by lipofectin mediated gene transfer. The transient expressive results were detected by immunohistochemical method. It was observed that the expression of human VEGF gene was detected 72 h after transfecting distinctly.
