In the pre-acute pancreatitis phase, the histological appearance of the pancreas is normal, even though the pancreas may be. pancreatic necrosis or following prolonged, complete proximal duct.

The pancreas is a mixed exocrine and endocrine gland that controls many homeostatic functions. The exocrine pancreas produces and secretes digestive enzymes, whereas the endocrine compartment consists.

. models in which mutant KRAS is targeted to the pancreas reveal that KRAS signalling is sufficient to reprogram pancreatic cells into duct-like lineages capable of progressing through preneoplastic.

Between 2003 and 2007 he commenced a post-doctoral research fellowship at the European Pancreas Center/Department of Surgery. Figure 2: Comparison of side-branch IPMN and main-duct IPMC by MRI and.

During embryonic development, pancreatic progenitors simultaneously proliferate and differentiate into the endocrine, ductal and acinar lineages. Using in vivo clonal analysis in the founder.
