Abstract:

Objective To systematically review the efficacy and safety of exosomes derived from bone marrow mesenchymal stem cells (BMSC) on animal models of spinal cord injury. Methods Animal studies about BMSC-derived exosomes for spinal cord injury were retrieved from databases of PubMed, Cochrane Library, Web of Science, CNKI and Wangfang Data, from establishment to October, 2021. Two researchers independently screened and extracted the data, and evaluated the risk of bias. The studies were qualitatively analyzed. Results A total of 21 studies were included, involving 1 342 animals. Male or female Sprague-Dawley rats were selected for 18 studies, and the body mass of the rats was (200±50) g in 19 studies. The injury nodes focused on T9-11 spinal cord, with various methods. The types, medication time, frequency, concentration and dose of the exosomes were heterogeneous. Conclusions The BMSC-derived exosomes can improve the motor function after spinal cord injury, reduce the damage of spinal cord, resist apoptosis and inflammation, reduce the permeability of blood-spinal cord barrier, and promote the growth of axons and blood vessels. More high-quality studies are needed for further verification.
