Which of the following is an example of xenotransplantation?
Xenotransplantation products must be alive, and circulation and return of patients’ blood must occur through live nonhuman cells. For example, human skin cells grown outside the body on a layer of nonhuman cells and then used in humans for skin reconstruction can also be considered a xenotransplantation product.
Why should xenotransplantation be banned?
He advocates a ban on xenotransplantation, largely on the grounds of the risk of the transfer of infection. Cells taken from carefully screened pigs have been used in the treatment of patients with diabetes, certain neurological diseases, and liver failure. The potential benefits of xenotransplantation are immense.
What is the importance of xenotransplantation?
The development of xenotransplantation can be seen as serving several purposes: to be a complete substitute for human organs; to supplement human organs, thus easing the current shortage available for transplantation; or to be a “bridge” organ before a “destination” organ can be found.
What is a xenotransplantation used for?
Xenotransplantation, or the transplantation of living tissues or organs from one species to another, alleviates the shortage of human organs such as heart and kidney. Pigs have a similar physiology and organ size, making porcine (pig) organs ideal candidates for transplantation into human recipients.
Is xenotransplantation used today?
What xenotransplants have been done? There have only been a few attempts at human xenografting over the years, but no human solid organ xenograft projects are currently approved by the FDA. “Baby Fae”, a child born with a malformed heart survived for a short period of time with a baboon heart.

Could xenotransplants be the future of organ donation?
Xenotransplants could save thousands of patients waiting for donated organs. The animal organ, probably from a pig or baboon could be genetically altered with human genes to trick a patient’s immune system into accepting it as a part of its own body.
When was the first xenotransplant performed?
The beginning of xenotransplantation history involved cells and tissues (blood, bone, skin), and not primarily vascularized organs [1,2]. In the seventeenth and eighteenth centuries, blood xenotransfusion  as well as bone and skin xenografts in humans was in fact reported .
