Pigs have a similar physiology and organ size, making porcine (pig) organs ideal candidates for transplantation into human recipients.

What are the disadvantages of xenotransplantation?

However, xenotransplantation is also associated with a number of concerns. These include immunologic problems (particularly the risks of hyperacute and acute rejection), the risk of xenogeneic infections, and many ethical, legal, and social concerns.

Human recipients have survived for as long as 20 years after transplantation, and the 10-year posttransplant survival rate is now approximately 45% (12).

What does xenotransplantation consist of?

Xenotransplantation is any procedure that involves the transplantation, implantation or infusion into a human recipient of either (a) live cells, tissues, or organs from a nonhuman animal source, or (b) human body fluids, cells, tissues or organs that have had ex vivo contact with live nonhuman animal cells, tissues or …

Why is xenotransplantation controversial?
