J Cell Physiol:大鼠鼻窦黏膜和骨膜来源的外泌体加速骨生成

2019-05-26 不详 网络

引导骨再生(GBR)通常用于牙槽骨增强。近年来,人们一直在强调骨组织工程领域的旁分泌机制,外胚胎被认为具有促进骨生成的潜力。我们旨在通过旁分泌刺激研究窦粘膜和骨膜对骨再生的影响,特别是通过外泌体,并比较它们之间的差异。在这里,我们报告来自鼻窦粘膜衍生细胞(SMC)和骨膜衍生细胞(PC)和分离的外泌体的条件培养基(CM)增强骨髓间充质干细胞(BM- MSCs)在体外的增殖,迁移和成骨分化。使用股骨缺

引导骨再生(GBR)通常用于牙槽骨增强。近年来,人们一直在强调骨组织工程领域的旁分泌机制,外胚胎被认为具有促进骨生成的潜力。我们旨在通过旁分泌刺激研究窦粘膜和骨膜对骨再生的影响,特别是通过外泌体,并比较它们之间的差异。

在这里,我们报告来自鼻窦粘膜衍生细胞(SMC)和骨膜衍生细胞(PC)和分离的外泌体的条件培养基(CM)增强骨髓间充质干细胞(BM- MSCs)在体外的增殖,迁移和成骨分化。使用股骨缺损的大鼠模型来证明源自SMC(SMC-Exos)和PC(PC-Exos)的外泌体可以加速体内骨形成。此外,我们初步讨论了SMC-Exos和PC-Exos对骨再生影响的可能功能成分。

总之,这些结果表明,鼻窦粘膜和骨膜可通过旁分泌作用加速骨生成,外泌体在此过程中起重要作用。
