Top 10 Commonly Confused Words in Xenotransplantation 1. Xenograft vs. Allograft Xenograft and allograft are two terms often interchanged. However, they have distinct differences. A xenograft is a transplant between different species, like from a pig to a human. On the other hand, an allograft is a transplant between individuals of the same species, such as from one human to another. 2. Hyperacute vs. Acute Rejection Hyperacute and acute rejection are terms used to describe the body's response to a transplant. Hyperacute rejection occurs almost immediately, within minutes or hours, due to pre-existing antibodies. In contrast, acute rejection happens over days or weeks and is caused by the recipient's immune system recognizing the transplant as foreign. 3. Heterograft vs. Xenotransplant While heterograft and xenotransplant both involve transplants between different species, there's a subtle difference. A heterograft refers to any such transplant, while xenotransplant specifically refers to the transplantation of animal organs or tissues into humans. 4. Isograft vs. Autograft Isograft and autograft are terms used for transplants within the same individual or between genetically identical individuals. An isograft is a transplant between individuals with identical genetic makeup, like identical twins. An autograft, on the other hand, is a transplant from one part of an individual's body to another.
