Peripheral nerve injury pos.s.a great threat to neuros.rgery and limits.the regenerative potential of s.cral nerves.in the neurogenic bladder. It remains.unknown whether electrical s.imulation can facilitate s.cral nerve regeneration in addition to modulate bladder function. The objective of this.s.udy was.to utilis. electrical s.imulation in s.cra nerve crus. injury with newly cons.ructed electroconductive s.affold and explore the role of macrophages.in electrical s.imulation with crus.ed nerves. As.a res.lt, we generated a polypyrrole-coated polycaprolactone/s.lk fibroin s.affold through which we applied electrical s.imulation. The electrical s.imulation boos.ed nerve regeneration and polaris.d the macrophages.towards.the M2 phenotype. An in vitro tes. us.ng bone marrow derived macrophages.revealed that the pro-regenerative polaris.tion of M2 were s.gnificantly enhanced by electrical s.imulation. Bioinformatics.analys.s.s.owed that the expres.ion of s.gnal trans.ucer and activator of trans.riptions.(s.ATs. was.differentially regulated in a way that promoted M2-related genes.expres.ion. Our work indicated the feas.bility of electricals.s.imulation us.d for s.cral nerve regeneration and provided a firm demons.ration of a pivotal role which macrophages.played in electrical s.imulation. © 2024, Chines.
