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.
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.
The National Organ Transplant Act (NOTA) of 1984 is an Act of the United States Congress that created the framework for the organ transplant system in the country. [1] The act provided clarity on the property rights of human organs obtained from deceased individuals and established a public-private partnership known as Organ Procurement and Transplantation Network (OPTN).
A transplant surgeon is a surgeon who performs organ transplants. Among the many organs that can be transplanted are: kidneys , livers , hearts , lungs , the pancreas , the intestine (especially the small intestine ), and recently, faces , tracheal (windpipe) tissue, and penises .
The discovery of the MHC and role of histocompatibility in transplantation was a combined effort of many scientists in the 20th century. A genetic basis for transplantation rejection was proposed in a 1914 Nature paper by C.C. Little and Ernest Tyyzer, which showed that tumors transplanted between genetically identical mice grew normally, but tumors transplanted between non-identical mice were ...
The four main types of tissue transplantation are xenotransplantation, allotransplantation, isotransplantation and autotransplantation, while the common tissues transplanted include skin, bone, corneal and vessel grafts. [3] Tissue transplantation comes with risks and complications, including immune rejection and viral infections.
Cytomegalovirus (CMV) is the most common opportunistic infection that may occur after a kidney and other solid organ transplants and is a risk factor for graft failure or acute rejection. [79] [81] BK virus is now being increasingly recognised as a transplant risk factor which may lead to kidney disease or transplant failure if untreated. [82]
