Corrigendum: Tissue-engineered nerve grafts using a scaffold-independent and injectable drug delivery system: a novel design with translational advantages (2019 J. Neural Eng. 16 036030).

This study has proposed a TENG using thermosensitive hydrogels as an injectable implant to controllably release NGF, which has promising therapeutic potential and translatability. Such TENGs obviate the need for conduit modification, complex preloading or binding mediators, therefore they allow the ease of drug switching in clinical practice and greatly simplify the manufacturing process due to the independent preparation of drug delivery system.
