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.

Why is xenotransplantation wrong?
Using the hearts of pigs for humans in need of transplants has been a major issue in xenotransplantation. There are dangers associated with such use, such as immunological rejection of the organ, endogenous viruses infecting the recipients, and issues of privacy.
What are the ethical issues of xenotransplantation?
Ethical issues concerning xenotransplantation include animal rights, allocation of resources, and distributive justice. In addition to obtaining consent for xenotransplants from individual patients, consent is also necessary from the populace, given the public health risks.
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.
What is the major barrier to successful transplantation across animal species xenotransplantation )?
The immunologic barriers to successful xenotransplantation are primarily related to the presence of natural anti-pig antibodies in humans and NHPs that bind to antigens expressed on the transplanted pig organ (the most important of which is galactose-α1,3-galactose [Gal]),5 and activate the complement cascade, which ...
What is 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.
What are the advantages of xenotransplantation?
What are the potential benefits of xenotransplantation? Xenotransplantation could potentially provide an unlimited supply of cells, tissues, and organs for humans. Any disease that is treated by human-to-human transplantation could potentially be treated by xenotransplantation.
What is the meaning of xenotransplantation?
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 ...
How much does a xenotransplantation cost?
The Institute of Medicine in 1996 tried to estimate what the actual cost of xenotransplantation would be in terms of health care. And they estimated the cost to $20 billion a year.
What are the benefits and risks of xenotransplantation?
Xenotransplantation has several potential advantages over allotransplantation 97: (i) it offers a virtually unlimited source of organs; (ii) scheduling is not dependent on the unpredictable availability of a donor human organ, allowing for both advance planning and the intentionally timed harvesting of an organ for ...
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.
When should xenotransplantation be used?
While still in the experimental stages, xenotransplantation is a potentially life-saving option for people with such ailments as severe heart disease and kidney failure. Preliminary data from experiments using transplanted pig cells in patients with diabetes and Parkinson's disease are encouraging.
Have there been any successful xenotransplantation?
The organ was successfully attached for three days in an experimental procedure on a brain-dead patient. It was the culmination of years of work; scientists have dreamed of xenotransplantation, in which organs from animals are put into humans, for decades.
Can a human live with a baboon heart?
Stephanie Fae Beauclair was the first human to receive a transplanted baboon heart from Bailey, and the last. A Loma Linda University spokesperson told The BMJ that Bailey never did a second transplant of a non-human heart on a human. Bailey spent the rest of his career at Loma Linda University.
What are examples of xenotransplantation commonly used in humans?
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.
When was the first successful xenotransplantation performed?
Remarkably, in 1838 the first corneal xenotransplantation (from a pig) was performed in a patient, whereas the first corneal allograft (human-to-human) was not carried out until more than 65 years later, in 1905.
