摘要:

背景:骨髓间充质干细胞对多种疾病具有治疗价值,其治疗疾病的线粒体转移机制是近年来被提出的新概念,具体作用机制及调控因素尚不明确。

目的:对现有关于干细胞及线粒体转移相关文章进行综述,并对其未来临床实际应用进行展望。
方法:第一作者应用计算机检索PubMed数据、维普、万方数据库中所有关于干细胞与线粒体转移相关文章。中文检索词为“干细胞、胚胎干细胞、祖细胞、线粒体”,英文检索词为“Stem Cell[s],Mother cell[s],Progenitor cell[s],Colony-Forming Unit[s],Colony Forming Unit[s],Mitochondria[l] transfer”,共检索到13篇文章,结合引文追踪法共纳入42篇文章进行综述。
结果与结论:骨髓间充质干细胞可以将具有正常功能的线粒体转移至损伤细胞,重建其有氧呼吸功能。细胞间通过形成连接管道结构进行线粒体转移,线粒体转移具有一定方向性。钙敏感性衔接蛋白Miro1对线粒体转移具有加速与引导作用。线粒体的成功转移可能伴随受体细胞内损伤线粒体的清除。早期防止线粒体损伤可能对包括急性肺损伤在内的很多疾病具有治疗意义。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells have beneficial effects on the treatment of various diseases. Mitochondria transfer is newly proposed and its specific mechanisms of action and control factors remain unclear.

OBJECTIVE: To review the studies about stem cells and mitochondrial transfer, then to discuss its value on clinical.
METHODS: The PubMed, VIP and Wanfang databases were searched for related articles concerning stem cells and mitochondrial transfer. Key words were “stem cell, embryonic stem cell, progenitor cell, mitochondria” in Chinese and “Stem Cell[s], Mother cell[s], Progenitor cell[s], Colony-Forming Unit[s], Colony Forming Unit[s], Mitochondria[l] transfer” in English. Thirteen articles were found initially, and using the citation tracking method, finally 42 articles were determined.
RESULTS AND CONCLUSION: Studies have shown that mitochondrial transfer from bone marrow mesenchymal stem cells is associated with rescue of aerobic respiration and restoration of mitochondrial function in the injured somatic cells. Bone marrow mesenchymal stem cells and recipient cells form tunneling nanotubes for mitochondrial transfer. Movement of mitochondria between cells is regulated and directed by Miro1. The successful transfer of mitochondria may be accompanied with the clearance of damaged mitochondria. The rescue of mitochondrial function in early stages may provide a valuable therapeutic strategy for various diseases include acute lung injury.
