The transplantation of the tissues or organs of one species or genus to another. Although some scientists argue that xenotransplantation could resolve many shortages in human transplantation, others argue that there are unknown health threats,...

Grafts between different species; see TRANSPLANTATION. These are contrasted with ALLOGRAFTS, grafts of tissue within the same species (rat to rat, human to human and so...

Viewpoint: Yes, xenotransplants from pigs should be prohibited because the risks of transmitting pig viruses to patients and the general population are too great. Viewpoint: No, xenotransplants from pigs raised at so-called organ farms should not be...

Xenotransplantation (xeno- from the Greek meaning "foreign") is the transplantation of living cells, tissues or organs from one species to another such as from pigs to humans (see Medical grafting). Such cells, tissues or organs are called xenografts or...

Imagine a moment in the (possibly not too distant) future, when xenotransplantation is considered clinically feasible. Animal studies--say, transplantation of pig kidneys into baboons--have been "successful," with survival of six to twelve months at a clinically acceptable level of immunosuppression. Genetic engineering has...

Within the past decade there has been a disproportionate increase in the waiting list of organ transplant candidates relative to a mounting shortage of organs available for transplantation. This issue has made it imperative that solutions to the shortage be investigated, including xenotransplantation,...

Xenotransplantation is the transplantation of animal organs into a human host body. This is usually a last resort due to the lack of accessibility to human organs and human organ donors.
