Abstract

Nanotopographical cues of bone implant surface has direct influences on various cell types during the establishment of osseointegration, a prerequisite of implant bear-loading. Given the important roles of monocyte/macrophage lineage cells in bone regeneration and remodeling, the regulation of nanotopographies on macrophages and osteoclasts has arisen considerable attentions recently. However, compared to osteoblastic cells, how nanotopographies regulate macrophages and osteoclasts has not been properly summarized. In this review, the roles and interactions of macrophages, osteoclasts and osteoblasts at different stages of bone healing is firstly presented. Then, the diversity and preparation methods of nanotopographies are summarized. Special attentions are paid to the regulation characterizations of nanotopographies on macrophages polarization and osteoclast differentiation, as well as the focal adhesion-cytoskeleton mediated mechanism. Finally, an outlook is indicated of coordinating nanotopographies, macrophages and osteoclasts to achieve better osseointegration. These comprehensive discussions may not only help to guide the optimization of bone implant surface nanostructures, but also provide an enlightenment to the osteoimmune response to external implant.

摘要

骨植入物表面的纳米形貌特征对成骨整合过程中各种细胞类型都有直接影响,而后者是植入物承载的前提。鉴于单核细胞/巨噬细胞谱系细胞在骨再生和重塑中的重要作用,纳米形貌对巨噬细胞和破骨细胞的调控最近引起了相当多的关注。然而,与成骨细胞相比,纳米形貌如何调控巨噬细胞和破骨细胞尚未得到很好的总结。在这篇综述中,首先介绍了巨噬细胞、破骨细胞和成骨细胞在骨愈合不同阶段的作用和相互关系。然后,总结了纳米形貌的多样性和制备方法。特别关注了纳米形貌对巨噬细胞极化和破骨细胞分化的调节特征,以及粘着斑-细胞骨架介导的机制。最后,对协调纳米形貌、巨噬细胞和破骨细胞以实现更好的骨整合进行了展望。这些综合讨论不仅有助于指导骨植入物表面纳米结构的优化,而且为骨免疫对外来植入物的反应提供了启示。
