Now scientists create a sheep that's 15% human

Chimera: sheep have 15 per cent human cells and 85 per cent animal cells
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 Ł5million perfecting the technique, which involves injecting adult human cells into a sheep's foetus.
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."

Stephen Hawking: humanity needs to live in space or die out, physicist warns via hologram
Humans should go and live in space within the next 1,000 years, or it will die out, Stephen Hawking has warned.
"We must continue to go into space for the future of humanity," Mr Hawking said. "I don't think we will survive another 1,000 years without escaping beyond our fragile planet."
Hawking issued the warning during one of two talks at the ...

A largely peaceful protest over the death of Freddie Gray, a 25-year-old black man who suffered a spinal cord injury in police custody, gave way to scattered scenes of chaos here on Saturday night, as demonstrators smashed a downtown storefront window, threw rocks and bottles and damaged police cruisers, while officers in riot gear broke up skirmishes and made 12 ...

What makes the academic study of â€śwhite supremacyâ€ť and â€śwhite privilegeâ€ť so perfect for racialists is that it requires absolutely no parameters of study. There are no standards of proof. There is no way any claims can be vetted in peer-reviewed journals because the â€śevidenceâ€ť can be explained by other factors. Anything and everything can be pointed to as being ...
