Xenotransplantation is the transplantation of cells, tissues or organs from one species to another such as from pigs to humans. Such cells, tissues or organs are called xenografts (xenotransplants). The terms heterograft and heterotransplant are also sometimes used, while the term homograft refers to a same-species transplant.
Xenotransplantation offers a potential treatment for end-stage organ failure, one of the most important health problems facing the industrialized world today. It also raises many novel medical, legal and ethical issues. A continuing concern is that cows and pigs have different lifespans than humans and their tissues age at a different rate. Disease transmission (xenozoonosis) and permanent alteration to the genetic code of animals are a cause for concern.
Because there is a worldwide shortage of organs for clinical transplantation about 60% of patients needing new organs die on the waiting list. In many cases there is so little chance of a person actually receiving a transplant, doctors do not even add the person to the list, causing an underrepresentation of the shortage. Recent advances in understanding the mechanisms of transplant organ rejection have brought science to a stage where it is reasonable to consider that organs from other species, probably pigs, may soon be engineered to minimize the risk of serious rejection and used as an alternative to human tissues, possibly ending organ shortages.
