Development and Structure of Pancreas

Abstract

The goal of this short chapter is to introduce the reader to fundamental concepts on the fine structure of the pancreas and its developmental pattern. This is of paramount importance for any individual that enters the field of pancreatology. In addition, this information is fundamental for understanding issues of histogenesis of pancreatic cancer, animal models, the histopathology of different forms of pancreatitis, pancreatic cysts and pancreatic cancer. The fine structure of the pancreas, as described here, is also essential as a foundation building block where to integrate, at the cellular level, the concepts from cell signaling, transcriptional regulation, secretion, proliferation, apoptosis, and senescence; all cancer-associated mechanisms. Thus, this is a basic, conceptual chapter that will serve as a compass for the reader of this book and in the field.
