Pig embryo used to grow human stem cells

Researchers in California and Spain have managed to grow human stem cells in a pig embryo.

It raises hopes that human organs could be grown for transplant operations, but that’s a long way away, said lead researcher Carlos Izpusua Belmont of the Salk Institute in California.

This is “just a very early step toward the goal,” he said.

The operation involved inserting three to 10 stem cells into pig embryos, then implanting the embryos in sows.

After three to four weeks, 186 embryos were removed and examined.

The research team found fewer human stem cells than they anticipated – less than one in 100,000 – but “we were very happy to see we actually can see thee human cells after four weeks of development
