ABSTRACT
Efficient bone reconstruction after bone injury remains a great challenge. Injectable supramolecular hydrogels based on amphiphilic peptide have been widely used due to their good biocompatability, non-immunogenicity, and manipulable physicochemical properties by sequence design. Herein, we used a well-studied hydrogelator, NapFFY, to coassemble with osteogenic growth peptide (OGP) to prepare a supramolecular hydrogel, NapFFY-OGP. Both in vitro and in vivo studies demonstrate that OGP was ideally synchronously, and continuously released from the hydrogel to effectively promote the regeneration and reconstruction of skull bone defects. More specifically, after the embedding the rat skull defect area with NapFFY-OGP hydrogels, a bone regeneration rate of 37.54% bone volume fraction (BV/TV) was achieved compared to that of NapFFY hydrogel group (25.09%). NapFFY-OGP hydrogel shows great promise in the clinic repair of bone defects in the future.
