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.

Key words: BMP2, TGF-1α, composite material, maxillary sinus
