The study of biliary physiology and pathophysiology has long been hindered by the lack of in vitro models that accurately reflect the complex functions of the biliary system. Recent advancements in 3D organoid technology may offer a promising solution to this issue. Bovine gallbladder models have recently gained attention in the investigation of human diseases due to their remarkable similarities in physiology and pathophysiology to the human gallbladder. In this study, the investigators successfully established and characterized bovine gallbladder cholangiocyte organoids (GCOs) that retain key characteristics of the gallbladder in vivo, including stem cell properties and proliferative capacity. Notably, their findings demonstrate that these organoids exhibit specific and functional cystic fibrosis transmembrane conductance regulator activity. These bovine GCOs represent a valuable tool for studying the physiology and pathophysiology of the gallbladder with human significance. Supported by ORIP (K01OD030515, R21OD031903).
