A potential treatment for sudden liver failure could cut the need for transplants, say scientists at the University of Edinburgh.
The liver has an incredible natural ability to repair itself, but this can be lost in some injuries including severe drug overdoses.
The therapy is a cancer drug that restores this regenerative potential.
The work is at a very early stage, but the team say alternatives to transplant would have a huge impact on patients.
Around 200 people in the UK have sudden life-threatening liver failure each year.
