Protective effect and potential mechanism of Schwann cell‐derived exosomes on mechanical damage of rat dorsal root ganglion cells

Pudendal nerve (PN) injury was one of the most important pathogenesis of stress urinary incontinence (SUI). Schwann cell (SC)‐derived exosomes could promote axonal regeneration. Wnt protein could significantly promote axonal regeneration and participate in the regulation of proliferation and differentiation of neural stem cells. Therefore, we sought to determine whether SCs‐derived exosomes might also protect against damaged dorsal root ganglion cells (DRGs) through the Wnt/β‐catenin pathway.
