[[abstract]]Peripheral nerve injuries mainly occur in the extremities and result in functional deficits, and recovery after microsurgical repair is slow (<1 mm/day) and frustrating. To improve the results of nerve repair, it is crucial to promote local Schwann cell (SC) function, neurite outgrowth, and to reduce perineural adhesion. In this study, a nerve wrap electrospun with Bletilla striata polysaccharide (BSP) and waterborne polyurethane (WPU) was designed to wrap around the repaired nerve to achieve the goal. In SC proliferation/migration tests and neurite outgrowth assay, BSP/WPU revealed considerable improvement. In rabbit sciatic nerve repair model, BSP/WPU exhibited significantly higher compound muscle action potential, muscle cont...
