Living Tissue Reverted Back to Embryonic State

We'll live forever! Except it causes tumors.

The living tissue inside an animal has been regressed back into an embryonic state for the first time, Spanish researchers say.

They believe it could lead to new ways of repairing the body, for example after a heart attack.

However, the study published in the journal Nature, showed the technique led to tumours forming in mice.

Stem cell experts said it was a "cool" study, but would need to be much more controlled before leading to therapies.
