Chronic/non-healing cutaneous wounds pose a debilitating burden on patients and healthcare system. Presently, treatment modalities are rapidly shifting pace from conventional methods to advanced wound care involving cell-based therapies. Mesenchymal stem cells (MSCs) have come across as a prospective option due to its pleiotropic functions viz. non-immunogenicity, multipotency, multi-lineage plasticity and secretion of growth factors, cytokines, microRNAs (miRNA), exosomes, and microvesicles as part of their secretome for assisting wound healing. We outline the therapeutic role played by MSCs and its secretome in suppressing tissue inflammation, causing immunomodulation, aiding angiogenesis and assisting in scar-free wound healing. We further assess the mechanism of action by which MSCs contribute in manifesting tissue repair. The review flows ahead in exploring factors that influence healing behavior including effect of multiple donor sites, donor age and health status, tissue microenvironment, and in vitro expansion capability. Moving ahead, we overview the advancements achieved in extending the lifespan of cells upon implantation, influence of genetic modifications aimed at altering MSC cargo, and evaluating bioengineered matrix-assisted delivery methods toward faster healing in preclinical and clinical models. We also contribute toward highlighting the challenges faced in commercializing cell-based therapies as standard of care treatment regimens. Finally, we strongly advocate and highlight its application as a futuristic technology for revolutionizing tissue regeneration.
慢性/非愈合性皮肤创面给患者和医疗系统带来了严重的负担。目前,治疗方式正从传统方法迅速向涉及细胞疗法的先进伤口护理转变。间充质干细胞(MSCs)因其多效功能,如非免疫原性、多能性、多谱系可塑性和生长因子、细胞因子、microRNAs (miRNA)、外泌体和微泡的分泌而成为一种有前途的选择,这些都是它们分泌组的一部分,有助于伤口愈合。我们概述了 MSCs 及其分泌组在抑制组织炎症、引起免疫调节、促进血管生成和协助无疤痕伤口愈合方面的治疗作用。我们进一步评估了 MSCs 在表现组织修复方面的作用机制。该综述探讨了影响愈合行为的因素,包括多个供体部位的影响、供体年龄和健康状况、组织微环境和体外扩增能力。接下来,我们概述了在植入后延长细胞寿命方面所取得的进展,旨在改变 MSC 货物的遗传修饰的影响,以及评估生物工程基质辅助传递方法在临床前和临床模型中的更快愈合效果。我们还强调了在将基于细胞的疗法商业化作为标准治疗方案方面面临的挑战。最后,我们强烈主张并强调将其作为一种具有变革性的组织再生技术的应用。
