Abstract
Human cholangiocyte organoids show great promise for regenerative therapies and in vitro modeling of bile duct development and diseases. However, the cystic organoids lack the branching morphology of intrahepatic bile ducts (IHBDs). Here, we report establishing human branching cholangiocyte organoid (BRCO) cultures. BRCOs self-organize into complex tubular structures resembling the IHBD architecture. Single-cell transcriptomics and functional analysis showed high similarity to primary cholangiocytes, and importantly, the branching growth mimics aspects of tubular development and is dependent on JAG1/NOTCH2 signaling. When applied to cholangiocarcinoma tumor organoids, the morphology changes to an in vitro morphology like primary tumors. Moreover, these branching cholangiocarcinoma organoids (BRCCAOs) better match the transcriptomic profile of primary tumors and showed increased chemoresistance to gemcitabine and cisplatin. In conclusion, BRCOs recapitulate a complex process of branching morphogenesis in vitro. This provides an improved model to study tubular formation, bile duct functionality, and associated biliary diseases.

Abstract
Enhancers and promoters are transcriptional regulatory elements whose facilitated interactions increase gene expression. Enhancer DNA sequences can be located far away from the promoter sequences that they regulate. Currently, the mechanism facilitating the establishment of enhancer-promoter interactions remains unclear. However, mutations causing errors in these interactions have been linked to cancer and disease, further conveying the need to understand the full mechanism. This review discusses multiple models that have been proposed to describe how enhancers go the distance to interact with promoters. Evidence supporting loop formation models is reviewed in addition to more complex hypotheses involving aspects of 3D chromatin organization and phase separation.
