Abstract:
Objective To investigate the effects of gene transfection with human growth/differentiation factor 5(hGDF5)on the differentiation and proliferation of rabbit bone marrow mesenchymal stem cells (BMSCs).Methods BMSCs were obtained from adult New zealand rabbits and purified by gradient centrifuge.Exogenous recombinant human GDF5 was transfected into BMSCs with liposome method.Then hGDF5 expression at mRNA and protein level was measured separately by reverse transcription-polymerase reaction and indirect immunofluorescence method.Activity of alkaline phosphates(ALP),expression of TypeⅡcollagen(ColⅡ),proteoglycan and growth of the cells were all measured by biological methods to evaluate the effects of hGDF5 gene transfer on the differentiation and proliferation of rabbit BMSCs.Results After hGDF5 gene transfection,BMSCs expressed hGDF5 mRNA and protein,and compared with the control groups,expression of proteoglycan and ColⅡ increased significantly,but no significant difference appeared in ALP activity and cell proliferation.Conclusion Gene transfer with hGDF5 is an effective way to enhance the expression of GDF5 at mRNA and protein.The expression of heterogenetic hGDF5 gene can induce BMSCs' differentiation to chondrogenic cells.But the gene transfection has no obvious effects on the proliferation and ALP activity of BMSCs.
