摘要

Here we report microribbon-based scaffolds as a novel platform to accelerate in vivo bone repair using in a critical sized, cranial defect model. In comparison with conventional hydrogels, the uRB-based scaffolds supported cell spreading, which may promote osteogenesis via mechanotransduction of cytoskeleton tension. Furthermore, the macroporosity of uRB-based scaffolds promoted cell proliferation, blood vessel ingrowth, and deposition of mineralized bone matrix. The platform reported herein may be particularly useful for repairing large defects of load-bearing tissues such as bone and cartilage.
