Here's the full article on The Mail:

Scientists have created the world's first human-sheep chimera - which has the body of a sheep and half-human organs.
The sheep have 15 per cent human cells and 85 per cent animal cells - and their evolution brings the prospect of animal organs being transplanted into humans one step closer.
Professor Esmail Zanjani, of the University of Nevada, has spent seven years and £5million perfecting the technique, which involves injecting adult human cells into a sheep's fetus.



He has already created a sheep liver which has a large proportion of human cells and eventually hopes to precisely match a sheep to a transplant patient, using their own stem cells to create their own flock of sheep.
The process would involve extracting stem cells from the donor's bone marrow and injecting them into the peritoneum of a sheep's foetus. When the lamb is born, two months later, it would have a liver, heart, lungs and brain that are partly human and available for transplant.


"We would take a couple of ounces of bone marrow cells from the patient,' said Prof Zanjani, whose work is highlighted in a Channel 4 programme tomorrow.


"We would isolate the stem cells from them, inject them into the peritoneum of these animals and then these cells would get distributed throughout the metabolic system into the circulatory system of all the organs in the body. The two ounces of stem cell or bone marrow cell we get would provide enough stem cells to do about ten foetuses. So you don't just have one organ for transplant purposes, you have many available in case the first one fails."


At present 7,168 patients are waiting for an organ transplant in Britain alone, and two thirds of them are expected to die before an organ becomes available.
Scientists at King's College, London, and the North East Stem Cell Institute in Newcastle have now applied to the HFEA, the Government's fertility watchdog, for permission to start work on the chimeras.


But the development is likely to revive criticisms about scientists playing God, with the possibility of silent viruses, which are harmless in animals, being introduced into the human

race.


Dr Patrick Dixon, an international lecturer on biological trends, warned: "Many silent viruses could create a biological nightmare in humans. Mutant animal viruses are a real threat, as we have seen with HIV."


Animal rights activists fear that if the cells get mixed together, they could end up with cellular fusion, creating a hybrid which would have the features and characteristics of both man and sheep. But Prof Zanjani said: "Transplanting the cells into foetal sheep at this early stage does not result in fusion at all."




Now scientists create a sheep that's 15% human | the Mail on Sunday

i wonder if this is a loophole in that law in Arizona where its illegal to have sex with sheep

Lol. Wow this is amazing... Look at the picture, too. I see a little human in there.

Reminds me of Full Metal Alchemist... heh heh. Kinda sickening. Kinda? Naw, extremely.

beofore ya know it there is going to be half humans and half bird, flying humans

im realy bad at science

i dont know how i feel about this...

poor sheep.

NO, THERE'S NOT. Humans will never be combined with anything and in a way I beleive that 'mixing animals' is just wrong. [oops sorry for the dabating >.>]

Plus, I predict humans will be extinct in the next million years. Haha.

Wow. I seriously read a book sorta like that. And I was like, "Wow. That's probably not going to happen for another century." Yeah. I was wrong.
