Abstract:

BACKGROUND: Exosomes are tiny membrane vesicle structures that are an important paracrine component of mesenchymal stem cells. They can transmit information to damaged cells or tissues for regeneration.

OBJECTIVE: To review the exosomes and their research process in regenerative medicine.

METHODS: Databases of PubMed and CNKI were retrieved with the keywords of “exosomes, mesenchymal stem cells, tissue regeneration and repair” in English and Chinese, respectively. After initial screening of titles and abstracts, irrelevant articles were excluded, and 63 eligible articles were included for result analysis.

RESULTS AND CONCLUSION: Exosomes contain a variety of components, and their extraction methods are diverse. They have various functions, such as removing waste material, mediating information transfer between cells, generating immune tolerance and serving as a tumor treatment vaccine. Mesenchymal stem cell-derived exosomes play an important role in tissue regeneration and repair, and have good application prospects. However, if they are used as cell-free therapy in clinical practice, more in-depth research and exploration are needed.

Key words: exosomes, mesenchymal stem cells, regenerative medicine, tissue defect, repair
