Wound repair is a complex challenge for both clinical practitioners and researchers. Conventional approaches for wound repair have several limitations. Stem cell-based therapy has emerged as a novel strategy to address this issue, exhibiting significant potential for enhancing wound healing rates, improving wound quality, and promoting skin regeneration. However, the use of stem cells in skin regeneration presents several challenges. Recently, stem cells and biomaterials have been identified as crucial components of the wound-healing process. Combination therapy involving the development of biocompatible scaffolds, accompanying cells, multiple biological factors, and structures resembling the natural extracellular matrix (ECM) has gained considerable attention. Biological scaffolds encompass a range of biomaterials that serve as platforms for seeding stem cells, providing them with an environment conducive to growth, similar to that of the ECM. These scaffolds facilitate the delivery and application of stem cells for tissue regeneration and wound healing. This article provides a comprehensive review of the current developments and applications of biological scaffolds for stem cells in wound healing, emphasizing their capacity to facilitate stem cell adhesion, proliferation, differentiation, and paracrine functions. Additionally, we identify the pivotal characteristics of the scaffolds that contribute to enhanced cellular activity.
伤口修复对临床医生和研究人员来说都是一项复杂的挑战。传统的伤口修复方法有几个局限性。基于干细胞的疗法已成为解决这一问题的新策略,在提高伤口愈合速度、改善伤口质量和促进皮肤再生方面显示出巨大潜力。然而,在皮肤再生中使用干细胞存在几个挑战。最近,干细胞和生物材料已被确定为伤口愈合过程的关键组成部分。涉及开发生物相容性支架、伴随细胞、多种生物因子以及类似天然细胞外基质(ECM)结构的联合疗法受到了广泛关注。生物支架包括一系列生物材料,这些材料作为接种干细胞的平台,为它们提供类似于ECM的有利于生长的环境。这些支架有助于干细胞的递送和应用,以促进组织再生和伤口愈合。本文全面综述了用于伤口愈合的干细胞生物支架的当前发展和应用,强调了它们促进干细胞黏附、增殖、分化和旁分泌功能的能力。此外,我们确定了有助于增强细胞活性的支架的关键特性。
