Engineering a biomimetic periosteum on cortical bone allografts for the reconstruction of critical-sized bone defects in mice
Load bearing bone allografts suffer from clinical failure due to low allograft-host tissue integration. Removal of the periosteum, a thin tissue layer on bone with a high regenerative capacity, is responsible for bone allografts' decreased clinical performance. This interdisciplinary project addressed this problem by creating multiple engineered periostea on mice bone allografts. Using a polysaccharide biomaterial, chitosan, tissue engineering scaffolds constructed on these bone allografts were modified with the glycosaminoglycan, heparin, and a chitosan derivative, trimethyl chitosan, to create ...
