背景:目前自体脂肪移植已广泛运用于美容整形和修复创伤导致的软组织缺损的修复,有研究表明,移植后1年移植脂肪存活率为20%-80%,因此,在移植后的早期及时、充分的血供建立,对于移植脂肪的存活是非常重要的。目的:观察血管内皮生长因子165转染人脂肪间充质干细胞的增殖情况。<br> 方法:体外传代培养人脂肪间充质干细胞,将重组血管内皮生长因子165基因入腺病毒液和空病毒液转染至脂肪间充质干细胞内,分别设为实验组和对照组,另设正常培养的细胞为空白组。<br> 结果与结论:RT-PCR,Western blot,MTT 检测显示,与对照组和空白组相比,实验组血管内皮生长因子165 mRNA和蛋白的表达及细胞增殖均增高(P<0.05)。结果证实,腺病毒承载的血管内皮生长因子165基因转染脂肪间充质干细胞后不仅可以持续的表达目的蛋白,同时也能显著促进脂肪间充质干细胞的增殖。
揹景:目前自體脂肪移植已廣汎運用于美容整形和脩複創傷導緻的軟組織缺損的脩複,有研究錶明,移植後1年移植脂肪存活率為20%-80%,因此,在移植後的早期及時、充分的血供建立,對于移植脂肪的存活是非常重要的。目的:觀察血管內皮生長因子165轉染人脂肪間充質榦細胞的增殖情況。<br> 方法:體外傳代培養人脂肪間充質榦細胞,將重組血管內皮生長因子165基因入腺病毒液和空病毒液轉染至脂肪間充質榦細胞內,分彆設為實驗組和對照組,另設正常培養的細胞為空白組。<br> 結果與結論:RT-PCR,Western blot,MTT 檢測顯示,與對照組和空白組相比,實驗組血管內皮生長因子165 mRNA和蛋白的錶達及細胞增殖均增高(P<0.05)。結果證實,腺病毒承載的血管內皮生長因子165基因轉染脂肪間充質榦細胞後不僅可以持續的錶達目的蛋白,同時也能顯著促進脂肪間充質榦細胞的增殖。

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. <br> OBJECTIVE:To observe the proliferation of human adipose-derived mesenchymal stem cel s transfected with vascular endothelial growth factor 165. <br> 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. <br> 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.
