Abstract

The biological characteristics and microenvironmental changes at each stage of tissue repair are intricately linked, maintaining a dynamic spatiotemporal equilibrium. Monotherapies often fail to effectively address complex microenvironmental disturbances, but combining multiple factors (e.g., physical and chemical) represents a promising approach to enhance tissue regeneration and repair. However, there is a lack of comprehensive reviews that explore the efficacy and mechanisms of combining physical and chemical factors to promote repair. A multidimensional understanding of the spatiotemporal specificity in tissue repair, coupled with the integration of spatiotemporal regulation principles into the design of smart-responsive biomaterials, is essential for regulating the local microenvironment and maintaining dynamic equilibrium. Based on this, this review first discussed the pathophysiological characteristics of spatiotemporal changes in tissue repair associated with several diseases. Second, the advantages and disadvantages of the current means of spatiotemporal modulation of physical and chemical factors commonly used for tissue repair were summarized. Finally, therapeutic strategies that utilize smart response materials to modulate these changes through physical and chemical factors are outlined. In addition, current challenges and future prospects for the use of smart-responsive biomaterials in spatiotemporal regulation of tissue repair were discussed.

摘要

组织修复各阶段的生物学特性和微环境变化紧密相连,维持着动态的时空平衡。单一疗法往往无法有效应对复杂的微环境紊乱,但结合多种因素(如物理和化学因素)是增强组织再生和修复的一种有前景的方法。然而,缺乏全面探讨结合物理和化学因素促进修复的疗效和机制的综述。对组织修复中时空特异性的多维理解,以及将时空调控原则整合到智能响应生物材料的设计中,对于调节局部微环境和维持动态平衡至关重要。基于此,本综述首先讨论了与几种疾病相关的组织修复时空变化的病理生理特征。其次,总结了目前常用于组织修复的物理和化学因素时空调节方法的优缺点。最后,概述了利用智能响应材料通过物理和化学因素调节这些变化的治疗策略。此外,还讨论了智能响应生物材料在组织修复时空调控中的当前挑战和未来前景。
