heterotopic transplantation  transplantation of tissue typical of one area to a different recipient site.

homotopic transplantation , orthotopic transplantation transplantation of tissue from a donor into its normal anatomical position in the recipient.

syngeneic transplantation  transplantation of a syngraft.

xenogeneic transplantation  transplantation of a xenograft.

transplantation

[-plantā′shən]

Etymology: L, transplantare, to transplant

the transfer of tissue from one site to another or from one person or organism to another.

---

transplantation

the transfer of living organs and tissue from one part of the body to another or from one individual to another. Transplantation and grafting mean the same thing, though the term grafting is more commonly used to refer to the transfer of skin. See grafting (1).

Occasionally an organ is transplanted from one place to another within the body (autotransplants). Kidneys, for example, have been relocated to enable them to continue functioning after the ureters have been damaged. See also graft rejection.

transplantation antigen

see histocompatibility antigen.

bone marrow transplantation

has been used in the treatment of a variety of hematopoietic and immunological disorders, e.g. in dogs with aplastic anemia.

corneal transplantation

full-depth and part-depth (lamellar) transplants are performed in animals when there is scarring of the cornea in the visual axis but the operation is difficult, the aftercare intensive and the failure rate high.

transplantation immunology

the study of immune responses that distinguish between self and nonself and the rejection of transplanted tissue or organs.

tendon transplantation

the procedure is not favored in horses where it was at one time used as a treatment for tendonitis. The success rate for return to racing performance is poor.

transplantation

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.

Patient discussion about Transplantation immunology.

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. Your cirrhosis is an indication for a liver transplantation, and your doctor should be aware of when you are suitable for transplant and put you on the transplant list. Patients are categorized according to the Child's Criteria method based on their developing of ascites, low albumiin level, encephalopathy (high amonia levels that affect the brain), and blood clotting problems.

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 :)
