OBJECTIVE: To investigate the effect of the micro ribonucleic acid (miR)-126-modified mesenchymal stem cell (MSC)-derived exosomes (MSC-exos) on the repair process of spinal cord injury (SCI) in rats. MATERIALS AND METHODS: MiR-126-modified MSCs were cultured, the exosomes were extracted, and a rat model of SCI was established. The Quantitative Polymerase Chain Reaction (qPCR) was carried … Continue reading Effect of exosomes derived from mir-126-modified mesenchymal stem cells on the repair process of spinal cord injury in rats
