Breakthrough in primate cloning

The US team has developed a new method for handling the donor egg

Experts have for the first time created cloned embryos from an adult monkey - a technical breakthrough that could bring efficient human cloning a step closer.
A team in the US created dozens of cloned embryos from a 10-year-old male macaque, the journal Nature reports.

This could make it easier to clone human embryos for use in research.

It raises the prospect of developing transplant tissues to treat diseases such as diabetes and Parkinson's that will not be rejected by the body.
