Comparative Study on Main Biological Characteristics of Pre-transfected Rabbit Marrow Stromal Cells and Post-transfected with pcDNA3-hBMP2

Wei Licheng,Liu Danping,Pu Qin,et al.Department of Orthopedics,the First People Hospital,Shaoyang,422000  
Objective To observe main biological characteristic and changes before and after MSCs were transfected with pcDNA3-hBMP2.Methods MSCs from an adult New Zealand white rabbit were isolated and cultivated.MSCs were divided into two groups.Group A was transfected with pcDNA3-hBMP2 and group B was not transfected as control group.Immunohistochemical staining was used for detecting BMP2 expressing 2 days after transfection.The cell morphological changes,cell divide index and cell cycle were observed after transfection.Results Rabbit MSCs could be successfully transfected by pcDNA3-hBMP2 through medium fugene 6 and express BMP2.Primary MSCs proliferated as short spindle shape,while post-transfected MSCs showed triangle-shape,and transfected-cells had significant difference in cell cycle and cell divide index.Conclusion Rabbit MSCs can be successfully transfected by pcDNA3-hBMP2 and after transfection many biological characteristics are significantly changed in this study.
