New hope in biliary disease


Cambridge research: Test-tube bile ducts open the door to new biliary disease therapies

‘Cholangiocytes’ are a type of cell that line the inside of bile ducts and modify the chemical make-up of passing bile.1 Historically, the lack of access to human cholangiocytes has hindered the study of biliary diseases, including the hereditary disorders Alagille syndrome, polycystic liver disease, and cystic fibrosis.2

Now, scientists at Cambridge’s Wellcome Trust MRC Stem Cell Institute have used human stem cells in the lab to create cells that function just like cholangiocytes.2 This breakthrough provides the means to model biliary diseases and to test new drugs, with no harm to patients.2 Indeed, the cells have already been used to test an exciting new treatment for cystic fibrosis, with positive results.2
