Multiple strategies enhance the efficacy of MSC-Exos transplantation for spinal cord injury
Spinal cord injury (SCI) is a relatively common and lethal dangerous disease of the central nervous system, for which there is a lack of effective clinical treatments. It has been found that mesenchymal stem cell-derived exosomes (MSC-Exos) play a key role in alleviating SCI through mechanisms such as regulating the microenvironment, promoting angiogenesis, and facilitating axonal regeneration. However, the drawbacks of natural exosomes, such as low yield, weak activity, and low targeting ability, limit their clinical applications. In recent years, MSCs-Exos have gradually become a research hotspot for treating SCI through miRNA modulation, combined hydrogel, and preculture. In addition, exosomes as good biocompatible drugs, nucleic acid, and other delivery carriers have shown a broad application prospect in treating SCI. This article summarizes the pathogenesis of SCI and the research progress of MSC-Exos in the treatment of SCI in recent years, and provides a systematic review of the mechanisms of MSC exosomes and their combination with different modalities in the treatment of SCI.
