Bioactive nerve conduit enhance peripheral nerve regeneration through dual functions of ion-regulated dedifferentiation and particle-anchored migration

Materials & Design
The regeneration of long-segment peripheral nerve defects remains a critical and challenging clinical problem. The key step in nerve regeneration involves the dedifferentiation of Schwann cells into a repair phenotype, followed by their orderly migration
