[L. transplanto, pp. -atus, to transplant]


The moving of a tissue or organ from one person–the donor or, less commonly, from a different site on the same person, to another person–the recipient, to replace a malfunctioning organ or organ system; solid organ and hematopoietic precursor transplantations are performed with increasing immunologic impunity in BM, bone matrix, heart valves, heart, heart-lung, kidney, liver, pancreas, skin and intestine, largely due to the availability of agents–eg, cyclosporine and tacrolimus–FK 506, which minimize the otherwise limiting complications of GVHD Complications Transplanted tumors Statistics Kidney 14,800; liver 5,350; heart 2155; lung 1042; kidney/pancreas 905; pancreas; 349; intestine 83; heart/lung 22; in Nov, 2003, 83,200 were on waiting lists at the 255 US medical centers that perform transplantations.

1. The grafting of donated organs or tissues into the body (homograft). Except in the case of identical twins, this process can succeed only if the rejection processes of the immune system are artificially suppressed.
2. The movement of tissue from one site to another in the same person (autograft). See also CTLA4-IG.


the transference of an organ or tissue from a donor to a recipient in need of a healthy organ or tissue. In recent years kidney, lung, heart and liver transplants have taken place. For successful transplantation to occur similar tissues types must be involved (see HLA SYSTEM and genetical similarity is one of the best ways of ensuring this. Drugs which inhibit the normal IMMUNE RESPONSES are used, but these also inhibit the body's defence against microorganisms. Rejection of foreign tissue is part of the normal response of the body and the development of drugs that will prevent rejection but which will not affect the normal response to microorganisms is actively being researched.


The removal of tissue from one part of the body for implantation to another part of the body; or the removal of tissue or an organ from one individual and its implantation in another individual by surgery.

Patient discussion about transplantation

Q. What is a bone marrow transplant? I wanted to enter myself as a potential bone marrow donor and wanted to know first of all what bone marrow is? What does a bone marrow transplant mean and how is it done?

A. Bone marrow is a soft, fatty tissue inside the bones. This is where blood cells are produced, and where they develop. Transplanted bone marrow will restore production of white blood cells, red blood cells, and platelets. Donated bone marrow must match the patient's tissue type. It can be taken from the patient, a living relative (usually a brother or a sister), or from an unrelated donor. Donors are matched through special blood tests called HLA tissue typing. Bone marrow is taken from the donor in the operating room while the donor is unconscious and pain-free (under general anesthesia). Some of the donor's bone marrow is removed from the top of the hip bone. The bone marrow is filtered, treated, and transplanted immediately or frozen and stored for later use. Transplant marrow is transfused into the patient through a vein (IV) and is naturally carried into the bone cavities where it grows to replace the old bone marrow.

Q. Has anyone had experience with a corneal transplant because of keratoconus?

A. my uncle had to do a transplant- it took 5 weeks until he could see anything , another year to get his vision straightened up. but now he is fine! i know that he looked for information in the "National Keratoconus Foundation". they were very helpful (and nice!), they have a website with information on all forms of treatment:

good luck :)

Q. I would like to know what it takes to get on a liver transplant list.. I have been diagnosed with cirrhosis of the liver. I have been clean and sober now over 2 years... I have also been hospitalized more times than i don't like talking about but I have been admitted for high amounts of ammonia levels, low blood pressure, and dehydration

A. Thank you for your answer. At my next GI appointment, the doctors told me that to have someone else that i'd like to be there at which time he will explain it all to me and either my brother or sister because i've have been admitted so many times because of ammonia levels, my brain has hardly no memory left. Let's all with this disease stick together.
