Human Organs From Pigs — But You’d Have to Kill One to Get One.
What if we could end the organ shortage tomorrow and everyone on the list could get a transplant within a few weeks? Would you be willing to endorse this new source of organs? If the source were a pig would you be willing to kill it to save your own life?
Xenotransplantation is the process of transplanting organs from animals into humans and historically that hasn’t worked too well. The human immune system immediately and violently attacks organs from animals and even our most powerful immunosuppressant drugs are ineffective but scientists are working on the problem because if we could use animal organs (ethical questions aside for now) we could end the organ shortage almost immediately.
The answer may lie in raising transgenic animals – animals that carry genes from other species or in the case of humans, animals that have been genetically modified so that their organs are transplantable into human beings.
According to www.actionbioscience.org Transgenic animals are not a pipe dream either, they are already being produced. The majority has been mice but scientists have also produced rabbits, pigs, sheep, and cattle. The primary question is not if we can raise pigs to produce organs for humans but when that is likely to happen and it’s possible it could happen relatively soon. In Korea scientists have already cloned a genetically altered pig with hopes of using its organs in humans but that has, to my knowledge, not yet been done successfully.
There are distinct medical applications to the process of transgenics and providing a ready supply of transplantable organs is one of them. Presently there is a single protein that can cause rejection but researchers think they can eliminate that problem in the not too distant future by replacing it with a human protein. It is also possible that animals could be raised to be disease resistant which would benefit both the animal and humans to which some animal diseases can cross.
Pigs are currently thought to be the best candidates for organ donation. The risk of cross-species disease transmission is decreased because of their increased phylogenetic distance from humans. They are readily available, their organs are anatomically comparable in size, and new infectious agents are less likely since they have been in close contact with humans through domestication for many generations.
Aside from growing organs for transplantation, milk producing animals are desirable, too, because they can be used to producenutritional supplements and pharmaceuticals. Products such as insulin, growth hormone, and blood anti-clotting factors may soon be or have already been obtained from the milk of transgenic cows, sheep, or goats. Research is also underway to manufacture milk through transgenesis for treatment of debilitating diseases such as phenylketonuria (PKU), hereditary emphysema, and cystic fibrosis.
So, yes, there are great possibilities with transgenic animals but there are also ethical concerns that must be addressed. For example:
- Should there be universal protocols for transgenesis?
- Should such protocols demand that only the most promising research be permitted?
- Is human welfare the only consideration? What about the welfare of other life forms?
- Should scientists focus on in vitro (cultured in a lab) transgenic methods rather than, or before, using live animals to alleviate animal suffering?
- Will transgenic animals radically change the direction of evolution, which may result in drastic consequences for nature and humans alike?
- Should patents be allowed on transgenic animals, which may hamper the free exchange of scientific research?
Animals like pigs offer hope for the thousands of people languishing on the national transplant list. Unfortunately these things take time and while scientists and then politicians and bureaucrats investigate the possibilities thousands will die waiting for organs. The altruistic system that we have in place in America just isn’t enough. We must do more to save the lives of those who need organs. Hope lies in xenotransplantation, regenerative medicine, therapeutic cloning and artificial organ development. We must keep that hope alive by support these efforts.

There is nothing you can do that is of greater importance. If you convince one person to be an organ and tissue donor you may save or positively affect over 60 lives. Some of those lives may be people you know and love.

Cheney Got a New Heart — Ethicists Need One
I am an average American male, human being. I’m not a genius not gifted just a man of normal intelligence who likes to think and read and research and write about about what I’ve found. Some things really stump me, though. I’m terrible at math, I love physics but don’t have a clue about how any of it works, and even after spending a good many years as a professional broadcaster I still don’t completely understand how the sound and picture got from me to your radio or TV. What mystifies me most, though, is the thought process of people who call themselves ethicists. The word is even hard to say, you kind of feel as though you have developed a lisp.
Just so we are all on the same page here, it is important to define our terms. First the Dictionary.com definition of ethics http://dictionary.reference.com/browse/ethics
eth·ics
[eth-iks] Show IPA
plural noun
1. ( used with a singular or plural verb ) a system of moral principles: the ethics of a culture.
2. (the rules of conduct recognized in respect to a particular class of human actions or a particular group, culture, etc.: medical ethics; Christian ethics.
3. moral principles, as of an individual: His ethics forbade betrayal of a confidence.
4.( usually used with a singular verb ) that branch of philosophy dealing with values relating to human conduct, with respect to the rightness and wrongness of certain actions and to the goodness and badness of the motives and ends of such actions.
Art Caplan of the University of Pennsylvania, the man who questioned whether the Vice President was too old to get a transplant, is a “Bioethicist.” The same Dictionary gives this definition.
bi·o·eth·ics
[bahy-oh-eth-iks] Show IPA
noun ( used with a singular verb )
a field of study concerned with the ethics and philosophical implications of certain biological and medical procedures, technologies, and treatments, as organ transplants, genetic engineering, and care of the terminally ill.
Having established who and what we are talking about let us return to the continuing saga of the Cheney heart transplant. The ethicists are rallying behind their colleague Art Caplan. One said, “The ethical issues are not that he (VP Cheney) got a transplant, but who didn’t?”
What an absurd argument! That could be said about anyone who got a transplant. if a 40 year old got a new liver, do we ask, “Who didn’t get the liver he just received?” I may not know much about ethics but I do have a clue about logic and somehow logic has been lost in the arguments forwarded by these learned people. I wonder how well any of them would do on “Are you smarter than a 5th grader.” Probably not real well being as that takes knowledge not philosophizing.
At the risk of sounding like a reactionary I have to say that some of these ethicists are the ones who got us in this donation shortage in the first place. For years the ethicists have been telling us that the only ethical way to obtain organs is through the “Altruistic” system which is what we have now — people voluntarily becoming donors. This method has been in effect since 1984. The problem is that it doesn’t provide anywhere near enough donors to satisfy the need, therefore from 6000 to 7000 people die each year while waiting for organs.
The ethicists have met many times to consider alternatives to altruistic donation and each time after a great deal of philosophizing, consternation and speculation have found that the alternatives are, you’ve got it, “unethical.”
Now I’m no rocket scientist and don’t have a PHD or a fancy title like “Bioethicist” but I do have common sense. It seems to me that if you are really concerned about ethics you would have to expand your thinking to a bigger picture. These ethicists appear to have quit thinking about the problem when they reached their myopic conclusion. They conveniently ignore the fact that people are still dying and will continue to die because they refuse to allow change. Doesn’t that deserve some of their “ethical” brainpower, philosophizing and speculation, too? It is amazing to me how strangely silent these “holier than thou” ethicists are about not questioning the ethics of allowing people to die.
There may be an explanation for their actions though and that explanation was found way back in 1931,long before transplants were considered possible. You see, even then the medical community was having problems with ethicists who considered themselves to be “Experts.” http://tinyurl.com/7c8fnho
Harold J. Laski writing in the London’s Fabian Society, manuscript in February of 1931, presented a challenge to the expertise of an “expert” in decision-making with the following:
:
“But it is one thing to urge the need for expert consultation at every stage in making policy; it is another thing, and a very different thing, to insist that the expert’s judgment must be final. For special knowledge and the highly trained mind produce their own limitations which, in the realm of statesmanship, are of decisive importance.
Expertise, it may be argued, sacrifices the insight of common sense to intensity of experience. It breeds an inability to accept new views from the very depth of its preoccupation with its own conclusions. It too often fails to see round its subject. It sees its results out of perspective by making them the centre of relevance to which all other results must be related. Too often, also, it lacks humility; and these breeds in its possessors a failure in proportion which makes them fail to see the obvious which is before their very noses.
It has, also, a certain caste-spirit about it, so that experts tend to neglect all evidence which does not come from those who belong to their own ranks. Above all, perhaps, and this most urgently where human problems are concerned, the expert fails to see that every judgment he makes, not purely factual to nature, brings with it a scheme of values which has no special validity about it. He tends to confuse the importance of his facts with the importance of what he proposes to do about them.”
I have no idea who Mr. or Dr. Laski was but his profound insight into the psyche of ethicists is a perfect reflection of my thoughts only articulated far more effectively.
I suppose there’s a role for ethicists to play in our society but at this point in my life (73 years worth) I don’t need a so-called ethicist to explain the difference between right and wrong to me. I’ve not studied the great philosophers to the extent they have but living as long as I have and having had a heart transplant has pretty much instilled in me a set of values that I think are pretty solid. That’s probably true about most people. We don’t need much help in making moral decisions. Do we want information? Sure. Will we accept advice? Sometimes. Do we need to have ethicists make decisions for us? Never! Unfortunately they do and It has cost thousands of lives.
