摘要:

文题释义:
压电生物材料:在外界应力或机体的运动作用下,能将机械应力产生的形变转化为电效应并产生电信号的生物材料。
血管化骨再生:骨再生的过程中伴随血管生成称为血管化骨再生。由于骨组织是高度血管化的组织,血管化过程在骨再生中至关重要,血管生成和骨再生重塑的复杂途径相互依赖并具有协同作用。在血管生成与骨生成这一高度耦合的过程中适当促进骨骼血管化可以有效促进骨再生。

背景:骨及血管组织的天然压电性能,吸引了大量关于压电材料在血管化骨组织再生领域的研究。因此,深入研究压电材料在骨及血管电学微环境下对细胞行为及组织再生的影响,有利于突破组织工程骨移植物新生血管化不足这一限制,实现其在临床中的广泛应用。
目的:综述压电生物材料在血管化骨再生研究领域中的应用及进展。
方法:以“压电材料,骨再生,血管化,血管生成”为中文检索词,以“piezoelectric material,bone regeneration,vascularization,angiogenesis”为英文检索词,在PubMed、Web of Science、中国知网数据库中检索发表于2011-2021年的相关研究论著。
结果与结论:压电生物材料具备良好的压电性能和生物相容性,可以通过压电作用产生电信号,刺激骨组织和血管组织,对组织再生进行调控,弥补惰性生物材料活性不足的缺陷,在血管化骨再生领域具有良好的应用前景。然而,目前调控压电材料促进组织修复的机制尚不明确,以血管化骨再生整体为目标的综合研究数量较少,压电材料性能方面也存在诸如不可生物降解及机械性能不足等缺点,亟待解决。

Abstract: BACKGROUND: Due to the inherent piezoelectric properties of bone and vascular tissues, piezoelectric materials have been developed and investigated in the field of vascularized bone tissue regeneration. Therefore, the effects of piezoelectric materials on cellular response and tissue regeneration in the electrical microenvironment of bone and vascular tissues were systematically investigated so as to overcome the limitations of insufficient neovascularization in tissue-engineered bone grafts, widening piezoelectric materials for their clinical applications.
OBJECTIVE: To review the application and progress of piezoelectric biomaterials in the field of vascularized bone regeneration.
METHODS: The key words included “piezoelectric material, bone regeneration, vascularization, angiogenesis” in Chinese and English. The articles published from 2011 to 2021 were searched on PubMed, Web of Science and CNKI.
RESULTS AND CONCLUSION: Piezoelectric biomaterials possessed excellent biocompatibility and superior piezoelectricity. The electrical signals generated from the piezoelectric effect not only stimulate bone and vascular tissues but also mediate tissue regeneration. Piezoelectric biomaterials can overcome the drawbacks of inert biomaterials without the bioactivity, exhibiting the promising prospects for application in vascularized bone regeneration. Nevertheless, the mechanisms for piezoelectric materials regulating tissue repair and regeneration remain unknown. There are few comprehensive studies targeting the overall regeneration of vascularized bone. The shortcomings of the performance of piezoelectric materials, such as non-degradation properties and insufficient mechanical properties, should be further improved. 

Key words: piezoelectric material, bone regeneration, angiogenesis, tissue engineering, piezoelectric polymers, piezoelectric ceramics, bone defect, vascularization
