Despite progress in bone tissue engineering, reconstruction of large bone defects remains an important clinical challenge. Here, we developed a biomaterial designed to recruit bone cells, endothelial cells, and neuronal fibers within the same matrix, enabling bone tissue regeneration. The bioactive matrix is based on modified elastin-like polypeptides (ELPs) grafted with laminin-derived adhesion peptides IKVAV and YIGSR, and the SNA15 peptide for retention of hydroxyapatite (HA) particles. The composite matrix shows suitable porosity, interconnectivity, biocompatibility for endothelial cells, and the ability to support neurites outgrowth by sensory neurons...
