^*Values are the mean ± SEM. Each group included seeded dorsal root ganglion (DRG) neurons isolated from 4 mice. MSC‐EV = mesenchymal stem/stromal cell–derived extracellular vesicle.

^† P < 0.01 versus control neurons by one‐way analysis of variance (ANOVA) followed by Tukey's post hoc test.

^‡ P < 0.05 versus nerve growth factor (NGF)–treated neurons by one‐way ANOVA followed by Tukey's post hoc test.
