Xenotransplantation is emerging as an innovative solution to the global organ shortage crisis, where the demand for transplants far exceeds the supply. This paper explores the historical need for an alternative source for allotransplantation and examines the key organs in play for such a transplant. It highlights the immunobiological barriers that challenge such a process, along with the risks of zoonotic disease transmission and the safety protocols to address them. Overall, the research findings prove that xenotransplantation presents a promising yet complex approach that could redefine modern medicine.
