Fibrosis, or scar tissue development, is associated with numerous pathologies and is often considered a worst-case scenario in terms of wound healing or the implantation of a biomaterial. All that remains is a disorganized, densely packed and poorly vascularized bundle of connective tissue, which was once functional tissue. This creates a significant obstacle to the restoration of tissue function or integration with any biomaterial. Therefore, it is of paramount importance in tissue engineering and regenerative medicine to emphasize regeneration, the successful recovery of native tissue function, as opposed to repair, the replacement of the native tissue (often with scar tissue). A technique dubbed 'mitochondrial transplantation' is a burgeoning field of research that shows promise in , and various clinical applications in preventing cell death, reducing inflammation, restoring cell metabolism and proper oxidative balance, among other reported benefits. However, there is currently a lack of research regarding the potential for mitochondrial therapies within tissue engineering and regenerative biomaterials. Thus, this review explores these promising findings and outlines the potential for mitochondrial transplantation-based therapies as a new frontier of scientific research with respect to driving regeneration in wound healing and host-biomaterial interactions, the current successes of mitochondrial transplantation that warrant this potential and the critical questions and remaining obstacles that remain in the field.
纤维化,即瘢痕组织形成,与多种病理状况相关,在伤口愈合或生物材料植入方面,通常被视为最糟糕的情况。剩下的只是一堆杂乱无章、紧密堆积且血管化不良的结缔组织束,而这里曾经是功能组织。这对组织功能的恢复或与任何生物材料的整合造成了重大障碍。因此,在组织工程和再生医学中,强调再生(即成功恢复天然组织功能)而非修复(即用瘢痕组织替代天然组织)至关重要。一种被称为“线粒体移植”的技术是一个新兴的研究领域,在预防细胞死亡、减轻炎症、恢复细胞代谢和适当的氧化平衡以及其他报道的益处方面,在[具体领域]和各种临床应用中显示出前景。然而,目前关于组织工程和再生生物材料中线粒体疗法潜力的研究还很缺乏。因此,本综述探讨了这些有前景的发现,概述了基于线粒体移植的疗法作为科学研究新前沿在促进伤口愈合中的再生和宿主 - 生物材料相互作用方面的潜力、线粒体移植目前的成功之处(这些成功证明了这种潜力)以及该领域仍然存在的关键问题和剩余障碍。
