'Chimeras' used to supply transplant organs

Scientists have been creating human-animal hybrids to help meet the growing demand for donor organs.
With transplant patients often having to wait years for organs, scientists have been looking for increasingly unorthodox ways to try and meet the ever-growing demand.

One of the most promising ideas, one which could have the potential to solve the problem entirely, involves injecting human stem cells in to an animal embryo with the aim of growing actual human organs that can be retrieved for use in transplants once the animal grows and matures.

The research is certainly not without its fair share of controversy however - in particular with regard to the extent to which the human cells will actually become incorporated in to the host.

"My view is that the contribution of human cells is going to be minimal, maybe three percent, maybe five percent," said biologist Pablo Ross from the University of California.

"But what if they contributed to 100 percent of the brain? What if the embryo is mostly human? Itís something we donít expect, but no one has done this experiment, so we canít rule it out."

People want to harp on how genetic manipulation is bad. Yes we need to test and test and test to get it right. Yes there will be mistakes. I can see a future where we've created a better us. Where children develop in artificial wombs to prevent external contamination. Even replacement organs grown through some other weird science. We are agents of evolution. It is by our hands that we change the world.

i feel this could be a great addition to the medical community but i don't know what the religious folk would think about this.

I own a precious dog, for some years now. She is a bright light in my life. However, if for some reason her life was necessary to be sacrificed or altered in some way in order to save the life of a human... even a total stranger... my compassion and love for humans must take priority. Would I be sad? Of course. But only sad for my precious dog. I would be greatly joyed that a human life was "saved"

Like they said, they haven't tried it yet, so they don't really know what they will get. I think they should try it and see what happens. I think it is worth the risk. Pallidin, if your life depended on me sacrificing my dog, sorry about your luck, that is not going to happen.

It has put a huge dent in progress, people misusing breeding principles to create... [More]

I feel that your life is much more important than the life of my dog. I'd like you post, but apparently we suddenly have a short quote on likes? I gave out about 5, and started getting no more positive vote messages. Very noble and decent of you. I love my Dogs like kids too, my Betty is nearing 5 now, with luck, she might get another 5 or 6 years yet. Maybe 8, who knows. A human lives for like 80 years. You would be extending a life dramatically. And I feel that is noble of you. It would be a difficult and painful decision, but one that would have far reaching consequences.

i feel this could be a great addition to the medical community but i don't know what the religious folk would think about this. Religious folk suicide people to death, another 10 in Istanbul today with 25 injured, so they can F.... off. Religious people are moronic, superstitious, f..kwits who do not think, cannot think, because they are too stupid, so they can stuff their opinions up their medieval orifices
