Scientists Grow Sheep Embryos Containing Human Cells (theguardian.com)
An anonymous reader quotes a report from The Guardian: Scientists say growing human organs inside animals could not only increase supply, but also offer the possibility of genetically tailoring the organs to be compatible with the immune system of the patient receiving them, by using the patient's own cells in the procedure, removing the possibility of rejection. "Even today the best matched organs, except if they come from identical twins, don't last very long because with time the immune system continuously is attacking them," said Dr Pablo Ross from the University of California, Davis, who is part of the team working towards growing human organs in other species. Ross added that if it does become possible to grow human organs inside other species, it might be that organ transplants become a possibility beyond critical conditions.
Ross and colleagues have recently reported a major breakthrough for our own species, revealing they were able to introduce human stem cells into early pig embryos, producing embryos for which about one in every 100,000 cells were human. These chimeras -- a term adopted from Greek mythology -- were only allowed to develop for 28 days. Now, at this week's meeting of the American Association for the Advancement of Science in Austin, Texas, the team have announced that they have managed a similar feat with sheep embryos, achieving an even higher ratio of human to animal cells. "About one in 10,000 cells in these sheep embryos are human," said Ross. The team are currently allowed to let the chimeric embryos develop for 28 days, 21 of which are in the sheep. While that might be sufficient to see the development of the missing organ when human cells are eventually combined with the genetically modified embryo, Dr Hiro Nakauchi of Stanford University, who is part of the team, said a longer experiment, perhaps up to 70 days, would be more convincing, although that would require additional permission from institutional review boards.

Is this how real sheeples are born?
That's nothing... Back home in Britain the Welsh have been combining human and sheep DNA for centuries.

I will get an extremely high paying job, and then use it as a cover to implement a Logan's Run type society where old people are 'retired.'
But do the scientists have the chops to prevent cannibalism?
going to go nuts over this.
How many cells does it take to make a human?
How many angels can dance on the head of a pin?

Yeah, you keep telling yourself that.
Although, now that the Obama "recovery" is over, you might be able to get some of Trump's CRUMBS!!!
How exactly do you know normal sheep feel any different?
The lambs produced won't move out of the basement and spend all day playing video games.

It seems incredible to me that this was done without public comment and regulation. This is extremely dangerous. First, it's a potential vector for diseases to jump inter-species. Second, it's a way to grow more unquestioning trump supporters.

While not trying to be dismissive, it's unclear that this would ever be a viable approach. It's really just a shotgun approach: put human cells in an early stage sheep blastocyst, and human cells are scattered throughout the tissues of the embryo. There's no selective approach to trying to only grow a heart from human cells, for instance. This means that the organ will still contain sheep cells, and therefore have the possibility of being rejected by the transplant recipient's body. Their work with mouse-rat chimeras was far more targeted, but that's because the techniques exist to do so in those species.
Absent developing the techniques available in rat and mouse model systems, I'd rather see them try to entirely replace one of the germ layers with human cells; the endoderm for instance. You'd basically get a sheep with a human digestive tract. You'd also avoid the problem of getting human cells in the sheep's central nervous system (e.g., brain), which probably happens with their current approach, and which they said would cause them to stop if it was significant.

Yeah, I'd like fries with that. Thanks.
