Nerve conduits provide an advanced tool for repairing the injured peripheral nerve that often causes disability and mortality. Currently, the efficiency of conduits in repairing peripheral nerve is unsatisfying. Here, we show a functional nanoparticle-enhanced nerve conduit for promoting the regeneration of peripheral nerves. This conduit, which consists of gelatin-methacryloyl (GelMA) hydrogels with drug loaded poly(ethylene glycol)- poly(3-caprolactone) (MPEG-PCL) nanoparticles dispersed in the hydrogel matrix, is rapidly fabricated by a continuous three-dimensional (3D) printing process. While the 3D-printed hydrogel conduit with customized size, shape and structure provides a physical microenvironment for axonal elongation, the nanoparticles sustained release the drug to facilitate the nerve regeneration. The drug, 4-((5,10-dimethyl-6-oxo-6,10-dihydro-5H-pyrimido[5,4-b]thieno[3,2-e][1,4]diazepin-2-yl)amino) benzenesulfonamide, is a Hippo pathway inhibitor with multiple functions including improving the proliferation and migration of Schwann cells and up-regulating neurotrophic factors genes. The descried functional nerve conduit efficiently induced the recovery of sciatic injuries in morphology, histopathology and functions in vivo , showing the potential clinical application in peripheral nerve repair. Functional nerve conduit provides a promising strategy alternative to autografts. In this work, we rapidly customized a nanoparticle-enhanced conduit by the continuous bioprinting process. This nanoparticle in the conduit can release a Hippo pathway inhibitor to facilitate the nerve regeneration and function restoration. The efficacy of the conduits is comparable to that of autograft, suggesting the potential clinical applications.
