{Abstract}: Cholangiopathies affect the biliary tree via various pathophysiological mechanisms. Research on biliary physiology and pathology, however, is hampered by a lack of physiologically relevant in vitro models. Conventional models, such as two-dimensional (2D) monolayers and organoids, fail to replicate the structural organization of the bile duct, and both the size of the duct and position of cells are difficult to manipulate in a controllable way. Here, we describe a bile duct-on-a-chip (BDOC) that phenocopies the open-ended tubular architecture of the bile duct in three dimensions which, when seeded with either a cholangiocyte cell line or primary cells, demonstrates barrier function similar to bile ducts in vivo. This device represents an in vitro platform to study the pathophysiology of the bile duct using cholangiocytes from a variety of sources.
