Endogenous regeneration is becoming an increasingly important strategy for wound healing as it facilitates skin's own regenerative potential for self-healing, thereby avoiding the risks of immune rejection and exogenous infection. However, currently applied biomaterials for inducing endogenous skin regeneration are simplistic in their structure and function, lacking the ability to accurately mimic the intricate tissue structure and regulate the disordered microenvironment. Novel biomimetic biomaterials with precise structure, chemical composition, and biophysical properties offer a promising avenue for achieving perfect endogenous skin regeneration. Here, we outline the recent advances in biomimetic materials induced endogenous skin regeneration from the aspects of structural and functional mimicry, physiological process regulation, and biophysical property design. Furthermore, novel techniques including reprograming, flexible electronic skin, artificial intelligence, single-cell sequencing, and spatial transcriptomics, which have potential to contribute to the development of biomimetic biomaterials are highlighted. Finally, the prospects and challenges of further research and application of biomimetic biomaterials are discussed. This review provides reference to address the clinical problems of rapid and high-quality skin regeneration.
内源性再生正成为伤口愈合中越来越重要的策略,因为它有助于激发皮肤自身的再生潜力以实现自我修复,从而避免免疫排斥和外源性感染的风险。然而,目前用于诱导内源性皮肤再生的生物材料在结构和功能上较为简单,缺乏精确模拟复杂组织结构和调节紊乱微环境的能力。具有精确结构、化学成分和生物物理特性的新型仿生生物材料为实现完美的内源性皮肤再生提供了一条有前景的途径。在此,我们从结构和功能模拟、生理过程调节以及生物物理特性设计等方面概述了仿生材料诱导内源性皮肤再生的最新进展。此外,还强调了包括重编程、柔性电子皮肤、人工智能、单细胞测序和空间转录组学等在内的新技术,这些技术有可能推动仿生生物材料的发展。最后,讨论了仿生生物材料进一步研究和应用的前景与挑战。本综述为解决快速、高质量皮肤再生的临床问题提供了参考。
