摘要:
正畸牙齿移动(OTM)是一个相当复杂的力学-生物学过程,其生物学基础是机械力介导下的牙周组织改建,表现为牙周膜压力侧的骨吸收和张力侧的骨沉积。人类牙周膜细胞(hPDLCs)具有分化为成骨细胞的能力,并且在维持体内稳态和牙周组织再生中起着重要作用。现今已有许多研究利用循环牵张应力(CTS)模拟正畸过程中的机械刺激是如何诱导张力侧hPDLCs向成骨细胞的分化过程。本文将综述hPDLCs作为应力感应细胞对力学信号做出初级感应,通过不同信号转导通路将初级信号转化为下游信号,调控hPDLCs基因表达及蛋白合成进而调控hPDLCs成骨分化,促进骨改建过程中如何响应CTS刺激,并着重于机械信号转导所涉及的分子信号及通路研究进展,为临床实施有效正畸牙齿移动,缩短正畸时间,提高正畸效率提供理论基础,并为正畸牙移动相关机制研究提供参考。
