Scientists Create Human-Sheep Chimera for Organ Donations

Though it's long way from sheep embryos with human cells to that point

(Newser) - Human-animal chimeras are taking over the barnyard. A year after a research team announced they had created the first animal-human chimera by way of pig embryos containing human cells, they've done it again, the Guardian reports. This time it's sheep embryos with human cells. The goal is to...

Scientists Create 1st Successful Animal-Human Chimeras

Embryos implanted in pigs were part human and part pig

(Newser) - Researchers have created part-human-part-pig embryos in what other scientists are calling an "exciting" step toward proving the viability of human-animal chimeras, the BBC reports. The researchers injected human stem cells into pig embryos, then implanted those embryos into adult pigs. After a month or so, the developing pig was...

US Government Is Once Again Funding Animal-Human Hybrids

As long as scientists don't create a super-smart pig or something

(Newser) - Deciding that, you know what, humans can play God after all, the National Institutes of Health is lifting a year-old moratorium on federal funding for the creation of partially human animal embryos, otherwise known as chimeras. NPR reports the NIH had instituted the moratorium over ethical concerns—like what happens...

Scientists: We Can Make Pigs Grow Human Organs

Process has already been used to make mice grow rat organs

(Newser) - Japanese researchers have hit on a stem cell breakthrough that they say could essentially solve the organ shortages problem—but fair warning, it’s weird. By injecting stem cells from rats into the embryos of mice that had been genetically modified to be unable to grow their own organs, the...
