“…They combine biocompatibility, biodegradability and high hydration with the ability to present specific amino acid sequences that can be recognized by cells to favor their adhesion, proliferation and differentiation [ 6 , 7 , 8 , 9 , 10 ]. Of particular interest are those prepared from fibrillar proteins [ 11 ]. In vivo, many of these proteins, such as several collagens, silk fibroin or keratin can form complex hierarchical structures constituting the architecture of most tissues [ 12 , 13 , 14 ].…”
