Abstract:

BACKGROUND: Mesenchymal stem cells have multi-directional differentiation potential and immunomodulatory properties. In recent years, mesenchymal stem cells have been favored by researchers in the repair of peripheral nerve injury.
OBJECTIVE: To summarize the efficacy of mesenchymal stem cells in the repair of peripheral nerve injury in recent years.
METHODS: The authors retrieved PubMed, ScienceDirect, Medline and CNKI databases for relevant articles published from January 2000 to February 2019. The key words were “peripheral nerve injury, mesenchymal stem cells, tissue engineering, exosomes, nerve guidance conduits, genetic engineering” in Chinese and English, respectively. Initially, 428 articles were retrieved, and finally 66 articles were included in result analysis.
RESULTS AND CONCLUSION: Mesenchymal stem cells can be locally injected into the site of peripheral nerve injury, effectively promoting the growth of axons, inhibiting inflammatory reactions around the injured site, and providing a suitable microenvironment for nerve repair. Mesenchymal stem cells-derived exosomes can be used to effectively solve negative factors caused by cell proliferation and host immunity response. Mesenchymal stem cells combined with nerve conduit scaffolds achieve better neurological repair concurrently. Genetic engineering techniques can be targeted to modify mesenchymal stem cells to design ideal seed cells that are more available for repairing peripheral nerve injuries. In conclusion, mesenchymal stem cells have unique advantages in peripheral nerve repair, which is an ideal strategy for tissue engineering.

Key words: mesenchymal stem cells, peripheral nerve injury, exosomes, nerve conduits, genetic engineering, tissue engineering
