Xenotransplantation and Pig Organs

The video explores the use of pig tissue in medical transplants, particularly heart valves, and the concept of xenotransplantation. It discusses the challenges of human organ transplantation due to immune rejection and highlights the advantages of using pig organs. Genetic engineering in pigs is examined as a way to reduce rejection risks. The video also looks at future possibilities in xenotransplantation, including using stem cells to create organs. The conclusion acknowledges the support of SciShow's patrons.

What is the term used for transplanting organs from one species to another?

• Autotransplantation

• Isotransplantation

• Allotransplantation

• Xenotransplantation

What protein is primarily responsible for organ rejection in human transplants?
