recipient(redirected from recipiency)
Also found in: Dictionary, Thesaurus, Medical, Legal.
a human being or animal in which an organ, tissue, or cells from another organism have been transplanted. Transplantation is performed for therapeutic purposes, as in the case of blood transfusions and heart and kidney transplants. It is also carried out in order to study organ and cell functions; an example is the transplantation of bone marrow to animals that have been subjected to ionizing radiation. In addition, transplantation is sometimes performed for cosmetic purposes. The main conditions for the survival of foreign organs, tissues, or cells are the choice of a suitable donor and suppression of immunity in the recipient before the transplantation takes place. An organism with a surviving transplant is termed a chimera.
