What does xenograft mean?
A xenograft refers to a graft of tissue or an organ transplant obtained from a donor of a different species from the recipient. This type of transplant is also known as a heterograft or xenotransplant. Xenografts are used in medical research and have potential applications in treating various diseases, such as organ failure. The use of xenografts raises concerns about immune rejection and disease transmission, and researchers are working to develop methods to overcome these challenges. Xenografts have been used in experimental treatments, including the transplantation of pig hearts into human patients. While still a relatively new and experimental field, xenografting holds promise for advancing medical treatment options.
nounA xenograft is a graft of tissue obtained from a donor of a different species from the recipient. It is a type of transplant that involves transferring cells, tissues, or organs from one species to another.

The term has its roots in the field of transplantation and has been used in medical contexts since the early 20th century. The concept of xenografting has been explored in various scientific fields, including immunology, tissue engineering, and regenerative medicine.
Usage notes
The term xenograft is often used in medical and scientific contexts, particularly in the fields of transplantation and tissue engineering. It has a formal tone and is not commonly used in everyday conversation.
