An allograft contains many of the beneficial characteristics of nerve autograft, such as three-dimensional microstructural scaffolding and protein components inherent to nerve tissue. [3] One of the adverse effects of nerve allotransplantation is the immunogenic response.
The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and ...
This kind of graft is known as a vital bone graft. [citation needed] An autograft may also be performed without a solid bony structure, for example, using bone reamed from the anterior superior iliac spine. In this case, there is an osteoinductive and osteogenic action, however, there is no osteoconductive action, as there is no solid bony ...
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
Transplant engineering (or allograft engineering) is a variant of genetic organ engineering which comprises allograft, autograft and xenograft engineering. In allograft engineering the graft is substantially modified by altering its genetic composition. The genetic modification can be permanent or transient.
Hence, similar tissue from another part of the body that is in excess is sourced as the autograft. [10] [11] This can be seen in procedures like autologous orthopedic transplant, which remains the "gold standard" of bone grafting methods through extracting grafts from places like the iliac crest and transplanting them to the targeted fracture ...
If the left sided outflow root needs to be enlarged to fit the pulmonary autograft, the procedure is called Ross-Konno. [3] An alternative to a pulmonary homograft is the stentless xenograft roots such as the Freestyle Porcine Aortic Root by Medtronic. [2] [12] An external Dacron graft can be used to reinforce the pulmonary autograft. [2]
