Xenograft: A surgical graft of tissue from one species to an unlike species (or genus or family). A graft from a baboon to a human is a xenograft.

Is it ethical to use animal organs to be transplanted to humans?

Another question would be is it legal -in your place-?


Thanks in advance!

Wow! Never really thought about this, it seems barbaric, but on the other hand.. If it was my child's life that could be saved by this procedure I would be all for it wine

If the most think it's ethical to eat animal organs, why not to be transplanted to humans?

But now that it has been proven that recipients of transplanted organs tend to experience memories of their donors....it would an interesting experiment to say the least.

Memory transfer from the donor to the recipient?
(I guess being both humans ??)


Interesting.

How does it happen?

Well, I'm no expert in this but in life cases that were studied: the following scenario would unfold...recipient of organ would suddenly have memories of playing a great golf shot or flying a plane... but had done neither in his life...
When the donor was questioned about this....he revealed, he both played golf & flew airplanes...
It was thus concurred that one's memories are stored everywhere in the body, in all the cells and only in the brain as previously thought...

Thanks Bspoken4 for that!
There are some reports back to 1700 about the human organs’ "memory" even before any organs had been transplanted.

That is fascinating.

There have been instances of it here. A woman was given a hog's liver until a human donor was found. It worked. (Pigs torso's are similar to a humans').

I would say it might be outright dangerous on account of a Virus deciding to jump species!
I believe that is one of the reasons why Science had second thoughts of using genetically modified Pig-organs in Humans!

Really?
That sounds interesting, thanks R. I will read some more about the compatibly.

That could be possible but there must be ways to neutralize the bad virus/organisms in the animal organ to be trasnplanted.

I read a fiction novel about the human-Cromosome 6,from which a part of it was extracted and inserted into an animal egg to develop the organs of an specif human, but a parasit in the organ of the donor(animal) was the clue to suspect a black-market operation in trasplanting animal organs to humans.

On one of the questions of this thread: -ethics aside- who can afford these transplants?

Xenotransplantation (xenos- from the Greek meaning "foreign"), is the transplantation of living cells, tissues or organs from one species to another. Such cells, tissues or organs are called xenografts or xenotransplants. In contrast, the term allotransplantation refers to a same-species transplant. Human xenotransplantation offers a potential treatment for end-stage organ failure, a significant health problem in parts of the industrialized world. It also raises many novel medical, legal and ethical issues. A continuing concern is that many animals, such as pigs, have a shorter lifespan than humans, meaning that their tissues age at a quicker rate. Disease transmission (xenozoonosis) and permanent alteration to the genetic code of animals are also causes for concern. A few successful cases of xenotransplantation are published.

It is not uncommon for patients and physicians to use the term "allograft" imprecisely to refer to either allograft (human-to-human) or xenograft (animal-to-human), but it is helpful scientifically (for those searching or reading the scientific literature) to maintain the more precise distinction in usage.

I think your post might fit better in the Greek words thread Conrad.

Permanent alteration of the genetic code of the animals???

Is it being already done in real life?

Human genome injected to animals' eggs and then the new born animals having some human components?

Geee. this subject is really fascinating and I will look for some scientific references.

That must be good business as well.
Just a thought.

I wouldn't invest. Not because it is unethical, but because it is backward. And dangerous.

lifeisadream: Not a Nobel Prize is needed for this.

First: get the pork’s genome ( I am sure it has been done)
Second: identify which chromosome (s) has those virus-diseases code in the pork's genome (done I would guess.
Third: remove-substitute the DNA sequences hosting the diseases-virus info of the porks.
Fourth: get some pork’s eggs (zygote) and transfer the new DNA info them.
Fifth: get new porkies with not virus-diseases.

Voilá!I wonder why I do not have a Nobel prize.

quite simple,hmm?laugh
