Bone marrow transplant can replace the transplant recipient's immune system with the donor's, and the recipient accepts the new organ without rejection. The marrow's hematopoietic stem cells —the reservoir of stem cells replenishing exhausted blood cells including white blood cells forming the immune system—must be of the individual who ...
Whole pancreas transplants from living donors are not possible, again because the pancreas is a necessary organ for digestion. At present, pancreas transplants are usually performed in persons with insulin-dependent diabetes who have severe complications. [citation needed]
This means that anyone may receive a transplant of a type-O organ, and consequently, type-O recipients are one of the biggest beneficiaries of ABO-incompatible transplants. [2] While focus has been on infant heart transplants, the principles generally apply to other forms of solid organ transplantation.
Akkina is one of the researchers involved with a phase 3 trial in organ transplant patients that uses stem cells taken from the organ donor in an attempt to wean the recipients off of these drugs ...
Organ and tissue transplantation treat a variety of medical problems, ranging from end organ failure to cosmetic surgery. One of the greatest limitations to organ transplantation derives from organ rejection caused by antibodies of the transplant recipient reacting to donor antigens on cell surfaces within the donor organ.

Xenotransplantation (xenos-from the Greek meaning "foreign" or strange [1] [2]), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [3] Such cells, tissues or organs are called xenografts or xenotransplants .
The overwhelming majority of deceased-donor organs in the United States are allocated by federal contract to the Organ Procurement and Transplantation Network, held since it was created by the Organ Transplant Act of 1984 by the United Network for Organ Sharing, or UNOS. (UNOS does not handle donor cornea tissue; corneal donor tissue is usually ...
The discovery of the MHC and role of histocompatibility in transplantation was a combined effort of many scientists in the 20th century. A genetic basis for transplantation rejection was proposed in a 1914 Nature paper by C.C. Little and Ernest Tyyzer, which showed that tumors transplanted between genetically identical mice grew normally, but tumors transplanted between non-identical mice were ...
