Allografts tissue source

H) Collagen derived from the same species as recipient Tissues derived from the same species, for example, tissue grafts for medical use derived from human cadaveric donors, are referred to as allografts. These tissues constitute a plentiful source of stmctural materials for use in surgical repair of the musculoskeletal system. In contrast to vital organs for transplantation that are utilized without modification, stmctural tissues such as bone and soft connective tissues must be processed to remove blood, cells, soluble proteins, and enzymes before they can be used in vivo. Allografts retain many of their intrinsic stmctural and biomechanical properties.
