Abstract:Spinal cord injury is a common clinical disease secondary to spinal cord fractures that causes patients with motor and sensory dysfunction or even paralysis. In recent years, exosomes have participated in the occurrence and development of various diseases as nanometer-sized cell particles, and have received extensive attention. Exosomes derived from spinal cord tissue cells during spinal cord injury affect the injury process and tissue repair. In addition, exosomes as a new treatment for spinal cord injury have been widely studied. The authors document the mechanisms of various exosomes from spinal cord tissue and the repair effects of various cell-derived exosomes in spinal cord injury, in order to deepen the understanding of the role of exosomes in spinal cord injury and provide new ideas for studying the course and treatment of spinal cord injury.
