Researchers from the US and Japan have succeeded in using stem cell and genomic editing technologies to transfer human cells into freshly generated sheep and goat embryos. They told the American Association for the Advancement of Science in Austin on Sunday that the chimeras, which contain cells from both species, developed for up to three weeks.

Hiro Nakauchi, who pioneered the research at the University of Tokyo, grew a mouse with a rat pancreas and a rat with a mouse pancreas. When cells from the rat-grown mouse pancreas were transplanted into a diabetic mouse, they made enough insulin to cure the condition without being rejected.

“The next step was to move into large animals,” Dr Nakauchi said. “This was prohibited in Japan so I decided to move to Stanford University in California to work with Professor Pablo Ross.”
