Transference of a tissue or organ, alive or dead, within an individual, between individuals of the same species, or between individuals of different species.
The stage of cancer during which cancer cells move into different parts of the body.
The act of transplanting something.
Implantation of a living body part, organ, or tissue graft from a donor.
The implantation of an organ or tissue from one part of the body to smother or from one person (the donor) to another (the recipient). Skin and bone grafting are examples of transplantation techniques in the same individual. A kidney transplant involves the grafting of a healthy kidney from a donor to replace the diseased kidney of the recipient. Heart transplants have also been carried out with limited success and a few liver transplants have also been attempted. Transplanting organs or tissues between individuals is a difficult procedure because of the natural rejection processes in the recipient of the graft. Special treatment (e.g. with immunosuppresive drugs) is needed to prevent graft rejection.
The grafting of living tissue from its normal position to another site or the transplantation of an organ or tissue from one person to another. Organs and tissues that have been successfully transplanted include the heart, lung, kidney, liver, pancreas, cornea, large blood vessels, tendon, cartilage, skin, bone, and bone marrow. Brain tissue has been implanted experimentally to treat patients with Parkinson’s disease. The matching of histocompatibility antigens that differentiate one person’s cells from another’s helps prevent rejection of donated tissues. Cyclosporine, tacrolimus, corticosteroids, monoclonal antibodies, and other immunosuppressive agents have been approx. 80% effective in preventing rejection of transplanted organs for 2 or more years.
The replacement of tissue with tissue from the person’s own body or from another person.
The process of moving tissues from one body to another, or from one area to another area of the same body.
