Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location. Organs and/or tissues that are transplanted within the same ...
Ovary transplantation, giving rise to successful pregnancies, will result in children who will have the genetic inheritance of the organ donor and not the recipient. It has so far only been carried out on identical twins, since the use of an ovarian transplant from a genetically identical donor prevents rejection of the donated organ.
A brain transplant or whole-body transplant is a procedure in which the brain of one organism is transplanted into the body of another organism. It is a procedure distinct from head transplantation, which involves transferring the entire head to a new body, as opposed to the brain only. Theoretically, a person with complete organ failure could ...
Xenotransplantation ( xenos- from the Greek meaning "foreign" or strange [ 1][ 2] ), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [ 3] Such cells, tissues or organs are called xenografts or xenotransplants. It is contrasted with allotransplantation (from other individual of ...
Organ transplantation and allocation is mired in ethical debate because of this limited availability of organs for transplant. In the United States in 2016, there were 19,057 kidney transplants, 7,841 liver transplants, 3,191 heart transplants, and 2,327 lung transplants performed.
Allotransplantation. Allotransplant ( allo- meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. [ 1] The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts.
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person ( auto- meaning "self" in Greek [1] ). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant.
Liver transplantation is a treatment option for end-stage liver disease and acute liver failure, although availability of donor organs is a major limitation. The most common technique is orthotopic transplantation, in which the native liver is removed and replaced by the donor organ in the same anatomic position as the original liver.
