ABSTRACT
[Objective]To observe the expression of osteogenic growth peptide(OGP) gene,which had been transfected into rabbit bone marrow stromal cells(BMSC) by adenovirus,and detect the proliferation and differentiation of rabbit bone marrow stromal cells after gene transfection in vitro.[Methods]pcDNA3.1-OGP was constructed by using gene clone and recombined technique.With the help of lipofectamine 2000,BMSC were transfected with pcDNA3.1-OGP.The positive cell clones were selected with G418.The expression of OGP gene was observed by RT-PCR.Alkaline phosphatase(ALP) activity and type I collagen in pcDNA3.1-OGP transfected bone marrow stromal cells were measured to observe the differentiation from bone marrow stromal cells into osteoblast lineage.[Results]The pcDNA3.1-OGP vector was constructed successful.According to analysis of RT-PCR,alkaline phosphatase(ALP) and type I collagen assay showed that OGP gene could be expressed in BMSC,and could induce bone marrow stromal cells differentiation into osteoblast lineage.[Conclusion]The pcDNA3.1-OGP vector can be constructed successfully and its expression is confirmed in BMSC.The expression of OGP in bone marrow stromal cells can induce BMSC differentiation into osteoblast lineage.
