Human 'cloning' creates embryonic stem cells

A form of cloning has been used to create personalised embryonic stem cells in humans, say researchers.

Genetic material was taken from an adult skin cell and transferred into a human egg. This was grown to produce an early embryo.

Stem cells have huge potential in medicine as they can transform into any other cell type in the body.

The technique used - somatic cell nuclear transfer - shot to fame in 1997 when Dolly the sheep, the first mammal to be cloned from an adult cell, was unveiled to the world.

David Shukman reports.
