Organ donation is the process when a person allows an organ of their own to be removed and transplanted to another person, legally, either by consent while the donor is alive or dead with the assent of the next of kin.
Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location. Organs and/or tissues that are transplanted within the same person's body are called autografts. Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source.
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood in order to replicate inside of a patient and to produce additional normal blood cells. It may be autologous, allogeneic or syngeneic.
Kidney transplant or renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD). Kidney transplant is typically classified as deceased-donor or living-donor transplantation depending on the source of the donor organ. Living-donor kidney transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient.
Canadian Blood Services is a non-profit charitable organization that is independent from the Canadian government. The Canadian Blood Services was established as Canada's blood authority in all provinces and territories except for Quebec in 1998. The federal, provincial and territorial governments created the Canadian Blood Services through a memorandum of understanding. Canadian Blood Services is funded mainly through the provincial and territorial governments.
The United Network for Organ Sharing (UNOS) is a non-profit scientific and educational organization that administers the only Organ Procurement and Transplantation Network (OPTN) in the United States, established by the U.S. Congress in 1984 by Gene A. Pierce, founder of United Network for Organ Sharing. Located in Richmond, Virginia, the organization's headquarters are situated near the intersection of Interstate 95 and Interstate 64 in the Virginia BioTechnology Research Park.
Transfusion-associated graft-versus-host disease (TA-GvHD) is a rare complication of blood transfusion, in which the immunologically competent donor T lymphocytes mount an immune response against the recipient's lymphoid tissue. These donor lymphocytes engraft, recognize recipient cells as foreign and mount an immune response against recipient tissues. Donor lymphocytes are usually identified as foreign and destroyed by the recipient's immune system. However, in situations where the recipient is severely immunocompromised, or when the donor and recipient HLA type is similar, the recipient's immune system is not able to destroy the donor lymphocytes. This can result in transfusion associated graft-versus-host disease. This is in contrast with organ/tissue transplant associated GvHD, where matching HLA reduces the incident of the complication.
The National Marrow Donor Program (NMDP) is a nonprofit organization founded in 1986 and based in Minneapolis, Minnesota, that operates the Be The Match Registry of volunteer hematopoietic cell donors and umbilical cord blood units in the United States.
The National Organ Transplant Act (NOTA) of 1984 is an Act of the United States Congress that created the framework for the organ transplant system in the country. The act provided clarity on the property rights of human organs obtained from deceased individuals and established a public-private partnership known as Organ Procurement and Transplantation Network (OPTN). The OPTN was given the authority to oversee the national distribution of organs.
Organ trade is the trading of human organs, tissues, or other body products, usually for transplantation. According to the World Health Organization (WHO), organ trade is a commercial transplantation where there is a profit, or transplantations that occur outside of national medical systems. There is a global need or demand for healthy body parts for transplantation, which exceeds the numbers available.

His work has been featured by the U.S. National Science Foundation for its practical relevance.
Kidney paired donation (KPD), or paired exchange, is an approach to living donor kidney transplantation where patients with incompatible donors swap kidneys to receive a compatible kidney. KPD is used in situations where a potential donor is incompatible. Because better donor HLA and age matching are correlated with lower lifetime mortality and longer lasting kidney transplants, many compatible pairs are also participating in swaps to find better matched kidneys. In the United States, the National Kidney Registry organizes the majority of U.S. KPD transplants, including the largest swaps. The first large swap was a 60 participant chain in 2012 that appeared on the front page of the New York Times and the second, even larger swap, included 70 participants and was completed in 2014. Other KPD programs in the U.S. include the UNOS program, which was launched in 2010 and completed its 100th KPD transplant in 2014, and the Alliance for Paired Donation.
Dorry L. Segev is the Marjory K. and Thomas Pozefsky Professor of Surgery at Johns Hopkins School of Medicine, professor of epidemiology at Johns Hopkins Bloomberg School of Public Health, and associate vice chair of the Department of Surgery at Johns Hopkins Hospital. He has made significant contributions to the field of transplantation, including developing a mathematical model to facilitate a nationwide kidney paired donation program, both in the US and Canada. He is also known for his role in getting the HIV Organ Policy Equity Act signed into law.
Donor-specific antibodies (DSA) are a concept in transplantation medicine and describe the presence of antibodies specific to the Donor's HLA-Molecules. These antibodies can cause antibody-mediated rejection and are therefore considered a contraindication against transplantation in most cases. DSA are a result of B cell and plasma cell activation and bind to HLA and/or non-HLA molecules on the endothelium of the graft. They were first described in 1969 by Patel et al., who found that Transplant recipients who were positively tested for DSA using a complement-dependent cytotoxicity crossmatch assay had a higher risk of transplant rejection. DSA can either be pre-formed or can be formed as a response to the transplantion.

Optimal kidney exchange (OKE) is an optimization problem faced by programs for kidney paired donations (also called Kidney Exchange Programs). Such programs have large databases of patient-donor pairs, where the donor is willing to donate a kidney in order to help the patient, but cannot do so due to medical incompatibility. The centers try to arrange exchanges between such pairs. For example, the donor in pair A donates to the patient in pair B, the donor in pair B donates to the patient in pair C, and the donor in pair C donates to the patient in pair A.
