Animal-to-Human Organ Transplant Experiments Cancelled

Spudley writes: "The BBC is reporting that experiments aimed at creating a pig with organs suitable for human transplant have been cancelled. Apparently the funding has been withdrawn, over fears of introducing new diseases to the human population. The research group involved is the Roslin Institute - the same people who brought us Dolly the sheep." Kinda creepy.

Stupidity dooms thousands to death

Another disgusting example of technophobia run amuck. I'm not overly surprised that it happened on the other side of the Atlantic as anti- genetic-engineering vitriol is quite strong over there. I see more and more ludditeism every day lately. David -- man signature

Remember the influenza epidemic of 1918??

[OldHorton]

I see some of you guys criticizing this company for their decision and bringing up stats on how many thousands of lives can be saved from this technology. However, have you heard about the influenza epidemic in 1918 that killed anywhere from 21-50 million people worldwide? Well, in the past few years they analyzed the genetics of that strain and found that it was most closely related to the swine flu. It mutated to humans and killed millions in short time. Years later there have been other instances of swine flu mutations as well that affected the world.

By genetically engineering pigs that are somewhere in between humans and real pigs, the risk of a new strain mutating to hit us goes up. Way up.

I feel for those that are in need of organs and I'm a fully body donor on my license but given the choice of thousands of lives risked or millions, I'd choose the former.

Threat of disease is NOT the key issue

[dlgree1]

AID's is only thought to have come from primate origin but most scientests agree that we don't really know where it came from other than somewhere in africa. And Mad Cow disease is a spongiforum of which there are plenty. It is basically a string of proteins outside of a viral shell that can get through the filters that blood goes through on its way to your brain. In order to get mad cow disease you must eat a cow that has eaten another cows brain. There was a simmilar outbreak with pigs in the late 1800's when as part of the slop that pigs got fed they also get fed pig. This is why you are still supposed to cook pork more than any other meat. Cross-Species infections have been happening for hundreds of years(black plague is the most nutorious but you also have cow pox[from which small pox probably evolved) and there isn't any evidance that Xenotransplantation will increase the likelyhood of them happening. dlgreen

Re:Threat of disease is the real issue

Unacceptable by what criteria? Keep in mind that all technology, no matter how beneficial, can cause harm to some people. Vaccines for example, cause fatal allergic reactions in some people. People kill themselves in car accidents. Abundant food supplies have contributed to obesity which in turn contributes to heart disease, diabetes, and cancer. Yet I wager few people would give up vaccines, cars, and abundant food supplies because of these negative side effects.

Yes, some people may become infected from pig organs, and other people may in turn contract disease from them. But we're not helpless in the face of disease. Pigs can be tested for the presence of pathogens prior to transplant. Individuals can be monitored for the presence of bacteria and viruses (and you can be sure that people receiving pig organs will be closely monitored.) Individuals who contract diseases can be quarantined.

Also, we already face the risk of become infected with diseases and parasites from other species. You can contract trichonosis by eating undercooked pork. Slaughterhouse workers are exposed to pig blood and offal on a daily basis. Transplant recipients are simply a new transmission vector among many other pre-existing vectors.

Finally, keep in mind that we can be certain that people will die if they don't get organ transplants. According to the Council of Europe's home page:

Nearly 40,000 patients are at the moment waiting for a kidney in Western Europe whilst the number of cadaveric donors remains stable at around 5,000 each year. This is also the case in USA where the gap between the number of available organs and patients on the waiting list is also very high. They have more than 30,000 patients on the waiting list and the number of cadaveric donors is around 5,000 each year. Mortality rates while waiting for a heart, liver or lung transplant generally range between 15% and 30% but are even higher in some reports depending on the type of the organ needed. In 1994 there were no suitable livers for some 400 European citizens and around a further 400 died while waiting for a heart.

Keep in mind that this doesn't represent the true need for organ transplants, as only patients who're most likely to benefit from a transplant are put onto the waiting list. The benefits of saving these patients lives, outweighs the admittedly unknown, but probably low, risk of disease transmission.
