Project description:Assays in bile duct cancer patients showed 984 CNVs in 306 CNV regions (CNVR) distributed throughout all 22 chromosomes. Bile duct cancer patients had a mean of 21.8 gains and 19.2 losses of genes, with an average of 35.9 CNVRs per patient. Frequent sites of gains were at chromosomes 22q11.22, 2p11.2-p.11.1, 14q32.33 and 17q12, whereas frequent sites of losses were at 19q12-q13.43.

Human bile cholangiocyte organoids originate from the extrahepatic bile duct and can repair bile duct scaffolds in vitro

Project description:Cholangiocyte organoids provide a powerful tool for characterizing bile duct epithelium and expanding cholangiocytes for tissue engineering purposes. However, this involves invasively obtained tissue-biopsies via surgery which is not preferential and limits the patient-specific capacities of these cultures. To overcome this, organoid culture were initiated from minimal invasive bile-samples obtained during routine clinical procedures. Characterization revealed that these bile-cholangiocyte organoids originate from the extrahepatic bile duct and are capable to repopulate human extrahepatic bile duct scaffolds. With this, bile duct tissue engineering as well as personalized disease modelling is in sight.
