Bioprinting of constructs for innervation. (A) SEM image of a poly(ethylene glycol) (PEG) nerve guidance conduits (A1) and the implanted nerve guide showing the organization of regenerated axon paths (A2, scale bar = 1.0 mm); adapted, with permission, from [122]. (B) 3D-engineered cellularized conduits for peripheral nerve regeneration with complex geometries, including multichannel (B1), bifurcation (B2) and reconstruction of patient’s sciatic nerve (B3); adapted from [123]. (C) SEM image of a nanoporous and multi-layered 3D structure in graphene-based nanomaterials for peripheral nerve restoration; adapted from [131].
