The method of labeled seed cells is one of hot research of the construction of tissue engineering bone field, construction of GFP recombinant lentiviral vector infected BMSCs induced into osteoblasts, and it has important research value.BMSCs were cultured by bone induced medium , expression of bone gene of alkaline phosphatase, osteocalcin and osteopontin , basic fibroblast growth factor and collgen-I detected by RT- PCR method. The construction of GFP recombinant lentiviral vector , gene sequencing and inverted fluorescence microscope detected its expression.Results of RT-PCR showed BMSCs successfully induced into osteoblasts , osteogenic gene of osteopontin and osteocalcin, alkaline phosphatase, basic fibroblast growth factor and collgen-I expressed at stage.Gene sequencing results confirmed that GFP recombinant lentiviral vector was successfully constructed, inverted fluorescence microscope detection, BMSCs induced into osteoblasts were successfully transfected by GFP recombinant lentiviral vector ,and the GFP expressed in the BMSCs.The GFP recombinant lentiviral vector successfully transfected BMSCs induced into osteoblasts ,GFP labeled BMSCs are good osteogenic function for the construction of tissue engineered bone.
