Bile ducts grown in lab can repair livers

A new way to repair diseased livers has been unveiled by researchers at the University of Cambridge. They've found a way to grow the cells that line the branching system of pathways inside the liver - the bile ducts. Problems with these structures are the leading causes of liver disease, and are also a common reason why livers offered for donation often cannot be used. Injected into injured bile ducts, the teams' new cells are able to re-surface the pathways and reverse the damage, including, critically, in experimental donor human livers. It's a big step forward. Chris Smith heard from Kourosh Saeb-Parsy, who is part of the team behind the work…
