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。

Abstract: Objective: To test the effects of BMP2 and TGF-1α on bone differentiation of canine bone marrow stem cells in vitro, and verify it in vivo. Methods: BMP2 and TGF-1α were 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-1α group was significantly higher than those of other groups, and the same as biological stability. Conclusion: The application of BMP2 and TGF-1α can significantly promote bone formation, which has clinical application prospects.
