摘要

Collagen is the most abundant protein in the animal kingdom and has a unique triple-helical structure. It not only provides mechanical strength to tissues, but also performs specific biological functions as a multifaceted signaling molecule. Animal-derived collagen is therefore widely used as a biocompatible material in vitro and in vivo. In this study, we developed a novel peptide-based material that mimicked both the polymeric properties and a selected biological function of native collagen. This material was prepared by end-to-end multiple disulfide cross-linking of chemically synthesized triple-helical peptides. The peptide polymer showed a gel-forming property, and receptor-specific cell binding was observed in vitro by incorporating a peptide harboring an integrin α2β1-binding sequence. Furthermore, cell signaling activity and biodegradability were tunable according to the polymer contents. The results demonstrated the potential of this material as a designer collagen.
