Which term describes the transplantation of tissue from one person to another?

The term that describes the transplantation of tissue from one person to another is "Allograft." In the context of transplantation, an allograft refers specifically to the transfer of tissue between individuals of the same species who are not genetically identical, such as from one human to another. This type of transplantation is commonly used in organ donation where tissues like skin, corneas, or organs like kidneys and hearts are shared among different individuals.

Understanding the distinction is crucial in this field because it highlights the importance of immunological compatibility and the potential for rejection. The body’s immune system may recognize the transplanted tissue as foreign, leading to rejection, which is a significant concern in allografting procedures.

In contrast, other terms refer to different transplantation scenarios. A xenograft is the transplantation of tissue from one species to another, an isograft involves transplantation between genetically identical individuals (like identical twins), and an autograft refers to tissue transplanted from one site on an individual's body to another site on the same individual. Each term reflects a specific relationship between donor and recipient that aids in understanding the various techniques and challenges in transplantation medicine.
