Vascular endothelial growth factor 165 promotes proliferation of human adipose-derived mesenchymal stem cells / 中国组织工程研究

ABSTRACT

BACKGROUND:Autologous fat transplantation has been widely used in soft tissue defect repair and cosmetic surgery, and the 1-year transplant survival rate is 20%-80%. Therefore, the establishment of timely and adequate blood supply at early period after transplantation is very important for the survival of transplanted fat tissues. OBJECTIVE:To observe the proliferation of human adipose-derived mesenchymal stem cel s transfected with vascular endothelial growth factor 165. METHODS:Human adipose-derived mesenchymal stem cel s were subcultured in vitro. Recombinant adenovirus carrying vascular endothelial growth factor 165 and blank virus were respectively transferred into adipose-derived mesenchymal stem cel s. Cel s cultured normal y served as blank group. RESULTS AND CONCLUSION:Compared with the control and blank groups, the expressions of vascular endothelial growth factor 165 mRNA and protein were higher in the experimental group (P<0.05). Experimental findings suggest that the recombinant adenovirus carrying vascular endothelial growth factor 165 transferred into adipose-derived mesenchymal stem cel s cannot only maintain the expression of target protein but also obviously promote the proliferation of adipose-derived mesenchymal stem cel s.
