With an aging population leading to an increase in diabetes and associated cutaneous wounds, there is a pressing clinical need to improve wound-healing therapies. Tissue engineering approaches for wound healing and skin regeneration have been developed over the past few decades. A review of current literature has identified common themes and strategies that are proving successful within the field: The delivery of cells, mainly mesenchymal stem cells, within scaffolds of the native matrix is one such strategy. We overview these approaches and give insights into mechanisms that aid wound healing in different clinical scenarios. We discuss the importance of the biomimetic niche, and how recapitulating elements of the native microenvironment of cells can help direct cell behavior and fate. It is crucial that during the continued development of tissue engineering in wound repair, there is close collaboration between tissue engineers and clinicians to maintain the translational efficacy of this approach.
随着人口老龄化导致糖尿病及相关皮肤伤口增多,临床迫切需要改进伤口愈合疗法。在过去几十年中,已经开发出用于伤口愈合和皮肤再生的组织工程方法。对当前文献的综述确定了该领域内已证明成功的共同主题和策略:在天然基质支架内递送细胞,主要是间充质干细胞,就是这样一种策略。我们概述了这些方法,并深入了解了在不同临床情况下有助于伤口愈合的机制。我们讨论了仿生微环境的重要性,以及重现细胞天然微环境的要素如何有助于指导细胞行为和命运。在伤口修复组织工程的持续发展过程中,组织工程师和临床医生之间密切合作以维持这种方法的转化效果至关重要。
