Biological prosthesis and methods of production and use
Products, processes, compositions, kits, and methods are provided for cartilage-derived implants. The implants can exhibit resistance to enzyme (e.g., collagenase, protease, etc.) digestion compared to the source tissue from which they were derived while still having one or more mechanical properties comparable to the source tissue from which they were derived. The implants can also have a plurality of molecular bridges between molecules of the cartilaginous material. The molecular bridges can connect one or more collagen fibrils and/or/with one or more glycosaminoglycans. The implants can also be treated with cationic detergent, packaged and sterilized with or without additional components, and surgically implanted into subjects.
