Abstract:

Traumatic brain injury (TBI) is one of the leading causes of death and disability. With the development of stem cell therapy and regenerative medicine, it is possible for mesenchymal stem cells (MSCs) transplantation to treat TBI and improve craniocerebral neurological dysfunction. Current studies have shown that one of the neuroprotective effects of MSCs is based on the secretion of a variety of bioactive substances, in which extracellular vesicles (EVs) play a certain therapeutic role. The mechanism of MSC-EVs may be related to neuroprotection, regulating immune response, promoting angiogenesis, increasing neurogenesis and protecting the blood-brain barrier. This article mainly introduces the research progress of MSC-EVs in the treatment of TBI.

Key words: Mesenchymal stem cells, Traumatic brain injury, Extracellular vesicles, Nerve repair
