Abstract (original English)
This study aimed to investigate the effects of mesenchymal stem cell exosomes loaded with Fe 3 O 4 magnetic particles (Fe 3 O 4 @ MSC-exo) on the survival and neural differentiation of PC12 cells. Exosomes were separated from Fe 3 O 4 magnetic nanoparticles-primed umbilical cord mesenchymal stem cells condition medium by ultracentrifugation and characterized by transmission electron microscopy, flow nano analysis, and western blotting. PC12 cells were treated with culture medium containing exosomes. The effects of Fe 3 O 4 @ MSC-exo on PC12 cell proliferation, migration, and neural differentiation were analyzed using CCK-8 assay, transwell migration assay, RT-qPCR, and immunofluorescence, respectively. Additionally, miRNA sequencing was performed on Fe 3 O 4 @ MSC-exo, followed by bioinformatic analysis of the results. We found that Fe 3 O 4 @ MSC-exo can promote PC12 cell proliferation, migration, and neural differentiation. According to the sequencing results, there were a total of 43 differentially expressed miRNAs. The present study indicated that Fe 3 O 4 @ MSC-exo might enhance nerve cell function, laying the foundation for targeted therapy of nerve injury.
