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 .
Allotransplant (allo-meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. [1] The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts.
Xenotransplantation is a cross-species tissue transplantation from animal to human. [ 10 ] [ 11 ] The development of blood vessel anastomosis opened the door for xenotransplantation during the 20th century, which led to numerous attempts in organ transplantations with tissues from nonhuman primates (NHPs).
However, xenotransplantation is often an extremely dangerous type of transplant because of the increased risk of non-functional compatibility, rejection, and disease carried in the tissue. In the opposite direction, attempts are being made to devise a way to transplant human fetal hearts and kidneys into animals for future transplantation into ...
Xenotransfusion (from Greek xenos-'strange, foreign'), a form of xenotransplantation, was initially defined as the transfer of blood from one species into the veins of another. [1] In most cases, it is a transfer of blood between a non-human animal and a human. However, further experimentation has been done between various non-human animal species.

For example, it may be used for something transplanted from an identical twin. When the cells are collected from the same patient on whom they will be used, a graft is called autologous. Syngeneic refers to a graft transferred between genetically identical animals or people. [1] A syngeneic graft is known as an isograft. [2]
