Frontline Gastroenterology Published Online First: [please include Day Month Year] doi:10.1136/flgastro-2016100759 INTRODUCTION Linear endoscopic ultrasound (EUS) has become established as a key diagnostic and therapeutic tool in pancreaticobiliary medicine over the last 20 years. EUS/ EUS-fine needle aspiration (FNA) is used in the diagnosis and staging of pancreatic and bil...

Notch receptors are involved in regulating the balance between cell differentiation and stem cell proliferation during the development of numerous tissues (Artavanis-Tsakonas, S., Matsuno, K., Fortini, M. E., 1995. Notch signaling. Science 268, 225-232). Here the expression of all four vertebrate Notch genes, their ligands, and some down-stream targets is analyzed during mouse pancreatic organo...

CD97 expression is related closely to the dedifferentiation and tumor stage in thyroid carcinomas. We systematically examined the role of CD97 and its closest relative, EMR2, in normal and malignant gastric, esophageal, and pancreatic tissue. The normal tissues were EMR2-, whereas CD97 was expressed slightly in the parietal cells of gastric mucosa and in exocrine pancreatic cells. Interestingly...

The morphology, microanatomy and innervation of the biliary tree of the Australian possum, Trichosurus vulpecula, was examined. The gross morphology of the gallbladder, hepatic and cystic ducts, and the course of the common bile duct, conforms to those of other species. The sphincter of Oddi has an extraduodenal segment that extends 15mm from the duodenal wall; within this segment the pancreati...

Pancreatic ductal adenocarcinoma is one of the most debilitating malignancies in humans. Currently, radiation and chemotherapy are ineffective, with median survival times after treatment of <12 months. Animal models that reflect the human condition and can be used to explore screening and therapeutic approaches are clearly desirable. One feature of human pancreatic adenocarcinoma is an exceedin...

INTRODUCTION Magnetic resonance cholangio-pancreatography (MRCP) is a valuable method for the evaluation of biliary and pancreatic diseases and a valuable alternative to endoscopic retrograde cholangiopancreatography (ERCP). It is noninvasive and does not require the use of contrast material or ionizing radiation. Since its introduction in 1991, this technique has significantly improved in spat...

HCO3- -rich fluid in the pancreatic juice (2-3 L/day) is secreted by epithelial cells lining the pancreatic duct tree, while digestive enzymes are secreted by acinar cells with a small amount of Cl- -rich fluid. Ductal HCO3- secretion is not only regulated by gastrointestinal hormones and cholinergic nerves but is also influenced by luminal factors: intraductal pressure, Ca2+ concentration, pat...

Regeneration or extensive new growth of the pancreatic duct has been report,ed by Fisher (1924b), and regeneration of pancreas tissue (acini and islets) from the pancreatic duct tissue have been reported by several investigators, Languesse and de la Roche (1902), Cecil (1911), Bensley and Clark (1914). These observations deal with regeneration of pancreas from duct tissue left in situ, such as ...
