Random House Webster's College Dictionary
xen•o•trans•plantˈzɛn əˌtræns plænt, -plɑnt, ˈzi nə-(n.)
a surgical procedure in which tissue or whole organs are transfered from one species to another species
The transplantation of biological or organic matter from a given species into a different one, especially when this matter has been altered (such as by genetic engineering)
Xenotransplantation, is the transplantation of living cells, tissues or organs from one species to another. Such cells, tissues or organs are called xenografts or xenotransplants. In contrast, the term allotransplantation refers to a same-species transplant. Human xenotransplantation offers a potential treatment for end-stage organ failure, a significant health problem in parts of the industrialized world. It also raises many novel medical, legal and ethical issues. A continuing concern is that many animals, such as pigs, have shorter lifespans than humans, meaning that their tissues age at a quicker rate. Disease transmission and permanent alteration to the genetic code of animals are also causes for concern. A few successful cases of xenotransplantation are published.
