摘要
目的:体外实验检测骨形成蛋白-2(BMP2)与转化生长因子-1α(TGF-1α)对犬骨髓干细胞(BMSCs)骨向分化的影响,并通过体内实验验证。方法:通过构建慢病毒过表达BMP2与TGF-1α载体,复合BIOSS骨粉植入犬上颌窦,检测新生骨形成量。结果:联合应用BMP2与TGF-1α侧的上颌窦成骨量明显高于其他组,并获得更高的生物学稳定性。结论:BMP2与TGF-1α的使用可明显促进骨形成,具有临床应用前景。
Objective:To test the effects of BMP2 and TGF-1αon bone differentiation of canine bone marrow stem cells in vitro,and verify it in vivo.Methods:BMP2 and TGF-1αwere overexpressed by constructing lentivirus,and then combined with BIOSS bone meal and implanted into the maxillary sinus of dogs.New bone formation and biological stability(by ISQ)were detected.Results:Bone formation in the combined application of BMP2 and TGF-1αgroup was significantly higher than those of other groups,and the same as biological stability.Conclusion:The application of BMP2 and TGF-1αcan significantly promote bone formation,which has clinical application prospects.
