Regulatory proteins have been identified in embryonic development of the endocrine pancreas. It is unknown whether these factors can also play a role in the formation of pancreatic endocrine cells from postnatal nonendocrine cells. The present study demonstrates that adult human pancreatic duct cells can be converted into insulin-expressing cells after ectopic, adenovirus-mediated expression of the class B basic helix-loop-helix factor neurogenin 3 (ngn3), which is a critical factor in embryogenesis of the mouse endocrine pancreas. Infection with adenovirus ngn3 (Adngn3) induced gene and/or protein expression of NeuroD/beta2, Pax4, Nkx2.2, Pax6, and Nkx6.1, all known to be essential for beta-cell differentiation in mouse embryos. Expression of ngn3 in adult human duct cells induced Notch ligands Dll1 and Dll4 and neuroendocrine- and beta-cell-specific markers: it increased the percentage of synaptophysin- and insulin-positive cells 15-fold in ngn3-infected versus control cells. Infection with NeuroD
The minor duodenal papilla is the opening of the accessory pancreatic duct into the descending second section of the duodenum. The minor duodenal papilla is contained within the second part of the duodenum. It is situated 2 cm proximal to the major duodenal papilla, and thus 5-8 cm from the opening of the pylorus. The gastroduodenal artery lies posterior. The minor duodenal papilla may or may not contain a functioning sphincter and patent duct. When present, the sphincter is known as the sphincter of Helly, and the duct the accessory pancreatic duct of Santorini. In 10% of people, the minor duodenal papilla is the prime duct for drainage of the pancreas, although in others it may not be present at all. Pain from the region will be referred to the epigastric region of the abdomen due to its associated dermatomes.[citation needed] The duct is an embryological remnant, however in a small majority of people drains the pancreas. The minor duodenal papilla represents the remnants of the opening of the ...
The mentioned outcomes confirm that intraductal pancreatic stent fragmentation is in fact an extremely rare complication of pancreatic endotherapy. In this short article we aim to be sensitive to the fact that a broken pancreatic stent may also occur in patients undergoing endoscopic treatment of main pancreatic duct disruption, regardless of the diagnosis of chronic pancreatitis. We agree with the majority of authors [2-4] that endoscopic procedures should be attempted at centers experienced in retrieval of broken pancreatic stents, despite the lack of guidelines for treatment of intraductal pancreatic stent fragmentation. We have developed in our medical center the strategy of endoscopic treatment of intraductal pancreatic stent fragmentation [1], which we also use in the patients with a proximally migrated pancreatic stent. According to our strategy, the first instrument used for retrieval of parts of the broken stent during each endoscopic procedure was rat-tooth grasping forceps (Figure 1). ...

For the first time, we have shown that transient obstruction of the SO produced by carbachol administration resulted in hyperamylasaemia and histological changes consistent with acute pancreatitis. These changes were comparable with those induced in possums with combined pancreatic duct ligation and CCK-8/secretin administration, a well established method on inducing hyperamylasaemia and acute pancreatitis in other species. In both the carbachol induced and pancreatic duct ligation with secretin/CCK-8 models, the concurrent increase in pancreatic duct pressure with a combination of pancreatic exocrine stimulation was necessary to produce hyperamylasaemia and acute pancreatitis.. The increase in pressure in the pancreatic duct was similar whether it followed pancreatic duct ligation or was induced by carbachol administration. The increase in plasma amylase in all cases corresponded with the increase in pancreatic duct pressure following pancreatic duct ligation or stimulated SO obstruction in ...
This antibody recognizes a protein of 165-170 kDa, identified as cystic fibrosis transmembrane conductance regulator (CFTR). CFTR is composed of two membrane-spanning domains (MSD), two nucleotide-binding domains (NBD), and an R domain. It is structurally similar to multidrug resistance (Mdr1) protein and both are members of the superfamily of ATP-binding cassette (ABC) transporters, also known as traffic ATPases, which are implicated in the movement of various substrates. The CFTR protein is a small conductance adenosine 3′,5′-cyclic monophosphate (cAMP)-activated chloride ion channel found in the apical membranes of epithelia within the pancreas, airway, intestine, bile duct, sweat gland, and male genital ducts. CFTR is a valuable marker of human pancreatic duct cell development and differentiation.. Primary antibodies are available purified, or with a selection of fluorescent CF® dyes and other labels. CF® dyes offer exceptional brightness and photostability. See the CF® Dye Brochure ...
It has been found by immunohistochemical staining that antigens normally found in gastric and/or intestinal epithelial cells are expressed in most differentiated duct cell carcinomas of the pancreas. Among 88 such tumors, 93% and 92%, respectively, expressed M1 and cathepsin E, markers of gastric surface-foveolar epithelial cells, 51% expressed pepsinogen II, a marker of gastroduodenal mucopeptic cells, 48% expressed CAR-5, a marker of colorectal epithelial cells, and 35% expressed M3SI, a marker of small intestinal goblet cells. Most of the tumors also expressed normal pancreatic duct antigens; 97% expressed DU-PAN-2, and 59% expressed N-terminus gastrin-releasing peptide. In agreement with these findings, electron microscopy revealed malignant cells with fine structural features of gastric foveolar cells, gastric mucopeptic cells, intestinal goblet cells, intestinal columnar cells, pancreatic duct epithelial cells, and cells with features of more than one cell type.

Hence, we performed comprehensive analysis by using cDNA microarray and elucidated possible BMP target genes in human pancreatic cancer cell line Panc-1 to clarify the molecular mechanism of BMP-induced EMT. The elucidated genes were confirmed its induction by real-time PCR. Among these up-regulated genes, the calcium-binding protein coding S100P was newly identified as a BMP target gene, and its induction was also found in normal human pancreatic duct epithelial cell line HPDE cells after BMP4 treatment. The S100P induction was further evaluated by Western blotting analysis. The siRNA-based knockdown of S100P repressed the BMP-induced cell migration in Panc-1 cells. The induction of S100P was repressed by Smad4 knockdown, indicating the involvement of canonical Smad signaling pathway. On the other hand, the cyclin-dependent kinase inhibitor p21/CIP1 was also induced by BMP4, and growth inhibitory effect was confirmed by BrdU incorporation assay and direct cell count.

The normal adult pancreas has a dual function and composition - the exocrine component that produces enzymes necessary for digestion of food and the endocrine component, necessary for insulin production and regulation of blood glucose levels. The exocrine component is composed of lobular units of acini, that discharge their secretions into progressively larger ducts that finally merge into the mainpancreatic duct - the duct of Wirsung and the accessory pancreatic duct of Santorini. The duct of Wirsung ends at the major duodenal papilla (papilla Vateri) and the duct of Santorini ends at a minor duodenal papilla. The pyramidal-shaped acinar cells are large with their apical areas filled by markedly eosinophilic zymogen granules and the basilar cytoplasm is deeply basophilic. The acinar cells at the central portion of the acinus (centroacinar cells) fuse with the intercalated duct that fuses with the acinus. The intercalated ducts combine to form the intralobular ducts, which are lined by small ...

Y1 - 2005. N2 - Some populations of the epithelial cells from the duct and ductular network of the mammalian pancreas have been isolated and maintained in vitro for up to 3 mo. These cells express many of the surface factors that are unique to them in vivo. They also retain significant drug- and carcinogen-metabolizing capacity in vitro. In this chapter we review the progression of the methods for the isolation, culture and maintenance in vitro for these cells from the earliest when only duct/ductular fragments were obtainable to the current ones which provide epithelial cells. The critical steps in the isolation process are identified and strategies are provided to facilitate these steps. These include the selection of tissue digestive enzymes, the importance of extensive mincing before culture and the ...

Islets of Langerhans were isolated from mouse pancreases and fixed in periodatelysine-paraformaldehyde. The fixed islets were then dissociated with trypsin and EDTA to yield cell suspensions that contained mainly four cell types; beta-cells, capillary endothelial cells, acinar cells, and pancreatic duct epithelial cells. The nonislet cells were probably associated wtih the surface of the isolated islets. The H-2 antigens of the dissociated pancreatic cells were labeled with an immunoferritin technique. Pancreatic duct epithelial cells showed specific ferritin labeling on their lateral cell membranes but not on apical microvillus membranes. Acinar cells were also labeled on lateral membranes, and the capillary endothelial cells were labeled on both the luminal and albuminal aspects of their surface membranes. In contrast, pancreatic beta-cells were unlabeled. The number of ferritin molecules per unit length of beta-cell membrane was essentially the same on cells from the antigenic strain and the ...

The pancreas is made up of glandular tissue and ducts (passages or tubes for substances to flow through). The main pancreatic duct (duct of Wirsung) drains pancreatic fluid from the pancreas into the duodenum. There are many small ducts branching from the main pancreatic duct. The main pancreatic duct joins the bile duct to form the ampulla of Vater. The ampulla of Vater is a wider duct that opens into the duodenum. Many individuals also have a small accessory duct (duct of Santorini) which extends from the main duct to the duodenum.. ...
The pancreas is a soft oblong organ located in the upper central region of the abdominal cavity, just behind the lower surface of the stomach. It has three portions: an expanded medial portion called the head, a central portion called the body, and a tapering lateral portion called the tail. The head is partially encircled by the C-shaped duodenum, the first portion of the small intestine. The pancreas is both an exocrine gland and an endocrine gland. The exocrine portion of the pancreas consists of acinar cells (which account for about 99 percent of all secretory cells in the pancreas) that are organized into numerous small clusters called acini. The acinar cells secrete a clear fluid called pancreatic juice, which plays a critically important role in the digestion of food within the small intestine. The pancreatic juice is usually delivered to the duodenum by way of two ducts, the main pancreatic duct and the accessory pancreatic duct. (In some people, the accessory duct disappears during ...
We have experienced six new cases of mucinous ductal ectasia of the pancreas. Muci-nous ductal ectasia is characterized by mucin secretion and dilatation of the main pancreatic duct. These tuinors have been reported with increasing frequency, especially in Japan, where in 1982, it was advocated that they represent a new clinical entity. ERCP revealed a dilated pancreatic duct in the absence of obstructing ductal strictures and amorphous filling defects in the main pancreatic duct. Endoscopic findings included a patulous ampullary orifice, bulging ampulla of the Vater and mucin secretion from an orifice. We reviewed a total of twenty six cases including our six, of mucinous ductal ectasia, which were reported in various Korean literature. Clinical and radiologic studies of the twenty six cases were performed. They included nineteen men and seven women, 40-79 years of age. Twelve patients had symptoms of epigastric pain. From endoscopic retrograde pancreatography, twenty four patients showed mucin ...
Pancreas divisum is the most common birth defect of the pancreas. In many cases, this defect goes undetected and causes no problems. The cause of the defect is unknown.. As a baby develops in the womb, 2 separate pieces of tissue join together to form the pancreas. Each part has a tube, called a duct. When the parts join together, a final duct, called the pancreatic duct, is formed. Fluid and digestive juices (enzymes) produced by the pancreas normally flow through this duct.. If the ducts do not join while the baby is developing in the womb, pancreas divisum results. Fluid from the 2 parts of the pancreas drains into separate areas of the upper portion of the small intestine (duodenum). This occurs in 5% to 15% of people.. If a pancreatic duct becomes blocked, swelling and tissue damage (pancreatitis) may develop.. ...
The findings in Figure 6C are the first to show regulation of native CFTR activity by any transporter and the combined results show that deletion of slc26a6 resulted in dis-regulation of CFTR in the pancreatic duct. Slc26a6 inhibits the activity of CFTR in the resting state, which likely prevents unnecessary fluid and HCO3− secretion. This is evident from the increased HCO3− permeability and fluid secretion in slc26a6−/− ducts that is eliminated by knock-down of CFTR. In addition, we showed previously that the pancreatic (Ahn et al, 2001) and salivary ducts (Luo et al, 2001; Park et al, 2002) express the HCO3− salvage mechanisms NHE3 and NBC3 that are active in the resting state and are inhibited by CFTR at the stimulated state (Ahn et al, 2001; Luo et al, 2001; Park et al, 2002). On the other hand, CFTR does not seem to regulate slc26a6 activity in the resting state because CFTRinh-172 and knock-down of CFTR did not reduce Cl−/HCO3− exchange activity of the unstimulated duct ...

The pancreas is comprised of separate functional units that regulate two major physiological processes: digestion and glucose metabolism. The exocrine pancreas consists of acinar and duct cells. The acinar cells produce digestive enzymes and constitute the bulk of the pancreatic tissue. They are organized into grape-like clusters that are at the smallest termini of the branching duct system. The ducts, which add mucous and bicarbonate to the enzyme mixture, form a network of increasing size, culminating in main and accessory pancreatic ducts that empty into the duodenum. The endocrine pancreas, consisting of four specialized cell types that are organized into compact islets embedded within acinar tissue, secretes hormones into the bloodstream. The α- and β-cells regulate the usage of glucose through the production of glucagon and insulin, respectively. Pancreatic polypeptide and somatostatin that are produced in the PP and δ-cells modulate the secretory properties of the other pancreatic cell ...

Researchers identified a new source of insulin-producing cells. Results of a new study show cells in the pancreas that produce insulin -- called beta cells -- can form after birth or after injury from another, unrelated kind of cell. The unrelated cells, called pancreatic duct cells, can differentiate into the insulin-producing cells.. The finding contradicts widely-cited research published in 2004 that suggested new beta cells could only come about through the division of existing beta cells.. This means that there is a population of pancreatic cells that can be stimulated, either within the body or outside the body, to become new beta cells, the cells that are lacking in diabetes, lead researcher Susan Bonner-Weir, Ph.D., a senior investigator in the Section on Islet Transplantation and Cell Biology at the Joslin Diabetes Center and Associate Professor of Medicine at Harvard Medical School.. In type 1 diabetes, insulin-producing beta cells are destroyed by the immune system, leading the ...

Duct epithelial cell - A cell type is a classification used to distinguish between morphologically or phenotypically distinct cell forms within a species.
In the stomach is approximately 3, due to the presence of HCL [Hydrochloric Acid], the structure below the stomach, the pancreas, produces digestive enzymes, the liver is responsible for the production of a substanc named bile and is stored in the structure called Gall Bladder. When food is released from the stomach into the small intestine, the ph is approximately 3, this stimulates the release of bile from the gall bladder through the bile duct and to pancreatic duct. So the bile mixes with the digestive enzymes. The point where the pancreatic duct reaches the food the bile has two effects: the first effect is to neutralise the stomach acid and to create a ph whih is approximately 7. This ph is the optimal ph for the digestive enzymes. The second effect of bile is that the fat molecules are broken down into smaller droplets this is a process known as emulsification. A common misunderstanding is that this is an enzyme action. The purpose of the bile breaking fat down into smaller droplets is to ...

Pain in the pancreas is characterized by placement in the upper third of the abdomen and spreading to the back. As a rule, the condition worsens after eating. Pain can be combined with nausea, vomiting, sensitivity when pressed in the upper third of the abdomen. Patients often have an oily, stenchy stool. Pain is placed in the upper third of the stomach can be caused by diseases of other organs, because the stomach, duodenum, liver and pancreas are located in the area nearby. The pancreas is located in the upper third of the abdomen, located behind the stomach and intestines. It produces a fluid that contains enzymes produced in pancreatic cells and secreted into small tubules. These tubules are joined like the branches of a tree and form the main pancreatic duct, through which the enzyme-containing liquid enters the duodenum. Enzymes are inside the pancreas in an inactive form, since otherwise they could digest it. They are activated in the duodenum to break down the food ...

The major duodenal papilla is an opening of the Common bile duct and Pancreatic duct into the duodenum. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion. The major duodenal papilla is situated in the second part of the duodenum, 7-10 cm from the pylorus, at the level of the second or third lumbar vertebrae. It is surrounded by the sphincter of Oddi, and receives a mixture of pancreatic enzymes and bile from the Ampulla of Vater, which drains both the pancreatic duct and biliary system. The junction between the foregut and midgut occurs directly below the major duodenal papilla. The major duodenal papilla is seen from the duodenum as lying within a mucosal fold. The minor duodenal papilla is situated 2cm proximal. The major duodenal papilla is occasionally found in the third part of the duodenum, the level of the vertebrae may be L2-3, and in about 10% of people, it may not receive bile. Additionally, in a ...

BACKGROUND: Characterization of molecular mechanisms underpinning development of pancreatic ductal adenocarcinoma (PDAC) may lead to the identification of novel therapeutic targets and biomarkers. SgK223, also known as Pragmin, is a pseudokinase and scaffolding protein closely related to SgK269/PEAK1. Both proteins are implicated in oncogenic tyrosine kinase signaling, but their mechanisms and function remain poorly characterized. METHODS: Expression of SgK223 in PDAC and PDAC cell lines was characterized using gene expression microarrays, mass spectrometry (MS)-based phosphoproteomics and Western blotting. SgK223 was overexpressed in human pancreatic ductal epithelial (HPDE) cells via retroviral transduction, and knocked down in PDAC cells using siRNA. Cell proliferation was determined using a colorimetric cell viability assay, and cell migration and invasion using transwells. Expression of markers of epithelial-mesenchyme transition (EMT) was assayed by quantitative PCR. SgK223 and Stat3 signaling was
Since acinar cell carcinoma(ACC)of pancreas is rare, we sometimes meet a case hard to make diagnosis before surgery.

Intraductal mucin‐hypersecreting neoplasm of the pancreas (IMHN) is a unique tumor that has a tendency to spread intraductally. The clinical outcome of IMHN generally is far better than that of pancreatic ductal cell carcinoma. Because of the presence of various cell atypia within the same tumor, it sometimes is difficult to make an accurate histopathologic diagnosis and, therefore, predict its biologic behavior. It has been shown that overexpression of c‐erbB‐2 protein in ...
TY - JOUR. T1 - Mucin-hypersecreting intraductal neoplasms of the pancreas. T2 - A precursor to cystic pancreatic malignancies. AU - Madura, James A.. AU - Wiebke, Eric A.. AU - Howard, Thomas.

Mucin-hypersecreting intraductal pancreatic neoplasms were first described in 1982 and have been observed in increasing numbers since. They are observed primarily by endoscopic retrograde cholangiopancreatography (ERCP) and are characterized by an intraductal papillary neoplasm that secretes thick mucin, causing pancreatic duct dilatation and obstructive pancreatitis. Methods. Twenty patients are presented, 14 male and six female, with an average age of 59 ± 11 years. All patients presented with abdominal pain, and most had nausea and vomiting, weight loss, and documented pancreatitis. Of the preoperative studies, ERCP was positive in all patients. Computed tomography scan, ...
Background: Pancreatic carcinoma has a poor prognosis. It is important to focus on early detection and treatment for improvement of the prognosis. Understanding the characteristics of TS1 pancreatic carcinoma (≤2 cm) could improve the treatment outcome of pancreatic carcinoma. Methods: Among 444 patients with conventional pancreatic carcinoma who underwent surgery at our facility, the study targeted 65 (14.6%) with a histopathological diagnosis of TS1 pancreatic carcinoma. We examined 65 cases of TS1 pancreatic carcinoma in reason for hospital visit, examination findings, histopathological findings, and treatment outcomes. Results: The detection rate of TS1 pancreatic carcinoma by ultrasonography was 83.1% for visualization of the tumor mass and 96.9% for main pancreatic duct dilatation. The corresponding rates for endoscopic ultrasound were 92.9% and 100%. With regard to postoperative outcome, 43.1% of patients had a recurrence; the site of recurrence was local in 24.6% and hepatic in 9
We aim to determine the imaging findings for differentiating malignant and benign BD-IPMNs (branch-duct type intraductal papillary mucinous neoplasms) and their diagnostic value through meta-analysis. Pooled diagnostic odds ratio with which to suggest malignant BD-IPMN was the highest for the presence of mural nodule, followed by main pancreatic duct dilatation, defined as diameter 5 to 7 mm, thick septum/wall, and cyst size greater than 3 cm ...
The pancreas performs both exocrine and endocrine functions. The exocrine pancreas consists of two parts, the acinar and duct cells. The primary functions of pancreatic acinar cells are to synthesize and secrete digestive enzymes. Stimulation of the cell by secretagogues such as acetylcholine (ACh) and cholecystokinin (CCK) causes the generation of an intracellular Ca2+ signal. This signal, in turn, triggers the fusion of the zymogen granules with the apical plasma membrane, leading to the polarised secretion of the enzymes. The major task of pancreatic duct cells is the secretion of fluid and bicarbonate ions (HCO3-), which neutralize the acidity of gastric contents that enter the duodenum. An increase in intracellular cAMP by secretin is one of the major signals of pancreatic HCO3- secretion. Activation of the CFTR Cl- channel and the CFTR-dependent Cl-/HCO3- exchange activities is responsible for cAMP-induced HCO3- secretion ...
Diabetes mellitus is commonly considered as a disease of a scant beta-cell mass that fails to respond adequately to the functional demand. Tyrosine kinases may play a role for beta-cell replication, differentiation (neoformation) and survival. Transfection of beta-cells with DNA constructs coding for tyrosine kinase receptors yields a ligand-dependent increase of DNA synthesis in beta-cells. A PCR-based technique was adopted to assess the repertoire of tyrosine kinases expressed in fetal islet-like structures, adult islets or RINm5F cells. Several tyrosine kinase receptors, such as the VEGFR-2 (vascular endothelial growth factor receptor 2) and c-Kit, were found to be present in pancreatic duct cells. Because ducts are thought to harbor beta-cell precursor cells, these receptors may play a role for the neoformation of beta-cells. The Src-like tyrosine kinase mouse Gtk (previously named Bsk/Iyk) is expressed in islet cells, and was found to inhibit cell proliferation. Furthermore, it conferred ...
Cell survival and proliferation requires metabolic activity that depends on oxygen and nutrients, such as amino acids and glucose. Pancreatic ductal adenocarcinoma (PDAC) is characterized by progressive inflammation and fibrotic desmoplasia, which impedes the tumors blood supply and creates a nutrient-poor environment yet paradoxically promotes the growth of the tumor. When nutrients are scarce, cells initiate a process called autophagy, in which cells break down nonessential proteins, lipids, and other macromolecules for use as biosynthetic metabolites. Autophagy is a survival mechanism for many types of nutrient-starved tumors. However, Sousa et al. (see also Kamphorst and Gottlieb) found that PDAC growth was supported by scavenging a key nutrient secreted from pancreatic stellate cells (PSCs) undergoing autophagy in the surrounding stroma. When cultured with conditioned media from various PSC lines, 8988T PDAC cells, but not nonmalignant pancreatic ductal epithelial cells, had increased ...

A simple method for the isolation of intact islets from the normal rat pancreas is described. The method is based upon disruption of the acinar parenchyma by injecting Hanks solution into the pancreatic duct system followed by incubation of the pancreas in collagenase. Islets can be separated rapidly from this mixture by sedimentation. The isolated islets release insulin in vitro and appear normal by light and electron microscopy after incubation. A centrifugation method is also described for isolation of large quantities of islets for biochemical studies.. ...
