Abstract

Currently, mesenchymal stem/stromal stem cell (MSC) therapy has become a promising option for accelerating cutaneous wound healing. In vivo reports have outlined the robust competences of MSCs to offer a solid milieu by inhibition of inflammatory reactions, which in turn, enables skin regeneration. Further, due to their great potential to stimulate angiogenesis and also facilitate matrix remodeling, MSCs hold substantial potential as future therapeutic strategies in this context. The MSCs-induced wound healing is thought to mainly rely on the secretion of a myriad of paracrine factors in addition to their direct differentiation to skin-resident cells. Besides, MSCs-derived exosomes as nanoscale and closed membrane vesicles have recently been suggested as an effective and cell-free approach to support skin regeneration, circumventing the concerns respecting direct application of MSCs. The MSCs-derived exosomes comprise molecular components including lipid, proteins, DNA, microRNA, and also mRNA, which target molecular pathways and also biological activities in recipient cells (e.g., endothelial cell, keratinocyte, and fibroblast). The secreted exosome modifies macrophage activation, stimulates angiogenesis, and instigates keratinocytes and dermal fibroblast proliferations as well as migrations concurrently regulate inherent potential of myofibroblast for adjustment of turnover of the ECM. In the present review, we will focus on the recent findings concerning the application of MSCs and their derivative exosome to support wound healing and skin regeneration, with special focus on last decade in vivo reports.

摘要

目前,间充质干细胞(MSC)疗法已成为加速皮肤伤口愈合的一种有前途的选择。体内报告概述了 MSC 强大的能力,通过抑制炎症反应提供一个稳定的环境,从而促进皮肤再生。此外,由于其刺激血管生成和促进基质重塑的巨大潜力,MSC 在这方面具有作为未来治疗策略的巨大潜力。MSC 诱导的伤口愈合主要被认为依赖于除了其直接分化为皮肤常驻细胞之外,还分泌多种旁分泌因子。此外,最近有人提出 MSC 衍生的外泌体作为一种有效的无细胞方法来支持皮肤再生,同时避免了直接应用 MSC 所引起的担忧。MSC 衍生的外泌体包含包括脂质、蛋白质、DNA、microRNA 和 mRNA 在内的分子成分,它们靶向受体细胞(如内皮细胞、角质细胞和成纤维细胞)中的分子途径和生物活性。分泌的外泌体改变巨噬细胞的激活状态,刺激血管生成,并刺激角质细胞和成纤维细胞的增殖和迁移,同时调节固有成纤维细胞的潜力以调整 ECM 的周转率。在本综述中,我们将重点关注有关 MSC 及其衍生的外泌体应用于支持伤口愈合和皮肤再生的最新发现,特别关注过去十年的体内报告。
