Final answer:
Xenotransplantation is being explored as an alternative to address the shortage of human organs for transplantation. Genetic modification of donor animals, such as pigs, and growing organs from individual's own cells are two approaches being researched. These methods aim to improve the success rates of transplantation procedures.
Step-by-step explanation:
Xenotransplantation, or the transplantation of animal organs into humans, is being explored as an alternative approach to address the shortage of human organs available for transplant. Genetic modification of donor animals, such as pigs, is one avenue of research being pursued. By removing genes responsible for immune rejection and eliminating the risk of viral infections, scientists hope to develop transplantable organs that are well-tolerated by the human recipient.
In addition, researchers are also investigating the possibility of growing new organs in vitro from an individual's own cells. This would eliminate the need for donor organs altogether and minimize the risk of rejection. However, this method is still in the early stages of development.
Overall, the exploration of xenotransplantation and organ growth techniques aims to overcome the limitations of organ availability and improve the success rates of transplantation procedures.
