Adv Healthc Mater:3D打印生物活性玻璃支架可显著增强成骨细胞迁移和膜外成骨作用

2018-06-30 MedSci MedSci原创

生物活性玻璃(BG)可以修复骨缺损,然而,目前还不清楚BG是否只具有骨增强的能力而不会产生任何骨缺陷。与骨缺损修复中的膜内成骨不同,膜外成骨发生在皮质骨外,骨祖细胞表现出逆转移。本文制备了纳米级生物活性玻璃支架(BGSs),并研究了其在膜外成骨过程中的作用和免疫调节相关机制。

使用外周巨噬细胞条件培养基培养来研究颅盖骨前成骨细胞BGS刺激后的体外迁移和分化。结果表明,促炎症环境显著促进前成骨细胞迁移,但对成骨分化的作用有限。然而,抗炎环境和BGS可显著增加前成骨细胞的成骨分化。体外膜外成骨评估表明,颅骨附近观察到活性骨生成。与刚植入后部皮下的支架仅有纤维组织植入相比,可以确定来源于颅骨细胞反向迁移的成骨细胞。

综上所述,该研究结果可为BG在骨再生中的应用提供新的视角,并探讨非造血环境中外周巨噬细胞的成骨免疫调节。
