Representative work: BACKGROUND: Olfactory ensheathing cells (OECs) serve as a bridge by migrating at the site of spinal cord injury (SCI) to facilitate the repair of the neural structure and neural function. However, OEC migration at the injury site not only faces the complex and disordered internal environment but also is closely associated with the migration ability of OECs. METHODS: We extracted OECs from the olfactory bulb of SD rats aged <7 days old. We verified the micro ribonucleic acid (miR)-145a-5p expression level in the gene chip after SCI and OEC transplantation using quantitative reverse transcription (qRT)-polymerase chain reaction (PCR). The possible target gene Plexin-A2 of miR-145a-5p was scree INTRODUCTION: Olfactory ensheathing cells (OECs) are important transplantable cells for the treatment of spinal cord injury. However, information on the mechanism of OEC-derived extracellular vesicles (EVs) in nerve repair is scarce. METHODS: We cultured OECs and extracted the OEC-derived EVs, which were identified using a transmission electron microscope, nanoparticle flow cytometry, and western blotting. High throughput RNA sequencing of OECs and OEC-EVs was performed, and the differentially expressed microRNAs (miRNAs) (DERs) were analyzed by bioinformatics. The target genes of DERs were identified using miRWalk, miRDB, miRTarBase, and TargetScan databases. Gene ontology and KEGG mapper t
