Methods:Eukaryonic expression vector(pcDNA3.1-B2) was transduced into NIH3T3 cells using SofastTM, a new generation cationic polymer gene transfection reagent. The positive cell clones were selected with G418. The stable transfection and expression of BMP2 in the NIH3T3 cells were determined by RT-PCR and immunohistochemical stain. Results: BMP2 mRNA was transcripted and expressed in the transfected NIH3T3 cells. Conclusion: With positive compound transfection, outside human BMP2 gene can be successfully transducted into NIH3T3 cells, which is the key step to induce periodontal cells to osseous phenotypes.展开更多
