Abstract:

BACKGROUND: Recent studies have confirmed that direct therapy of mesenchymal stem cells has limitations, and their secretory function has been paid more and more attention. Exosomes are membrane vesicles released from the fusion of intracellular bodies and cell membranes inside the cells, which are tools for cell-to-cell communication and an important part of the secretion of mesenchymal stem cells.
OBJECTIVE: To summarize and analyze the role of mesenchymal stem cell exosomes in tissue repair, in order to provide new directions and ideas for basic research and clinical prevention and treatment of regenerative medicine.
METHODS: PubMed database and Embase database were retrieved by computer with the English words of “exosomes, extravesicles, MSCs, mesenchymal stem cells, regenerative medicine”; CNKI database, WanFang database and VIP database were retrieved by computer with the Chinese key words of “regenerative medicine, tissue repair, exosome, mesenchymal stem cells”. Articles describing the characteristics and repair effects of exosomes derived from mesenchymal stem cells in the past 10 years were included, and case reports, reply letters, summaries of conferences, gray literature at home and abroad, and articles with low quality of research were excluded.
RESULTS AND CONCLUSION: Mesenchymal stem cells have a very low overall content in the body, and their survival time is very short, which often fails to reach the effective time. The exosomes secreted by mesenchymal stem cells contain genetic information, which can be transported over a long distance and have the ability to act on target cells. It plays an important role in the protection and nutrition of nerve tissue, regulation of vascular regeneration, tissue repair of visceral diseases, wound healing and tissue repair, bone and cartilage regeneration.

Key words: Exosomes, Mesenchymal Stem Cells, Tissue Engineering
