To define genetic pathways that regulate development of the endocrine pancreas, we generated transcriptional profiles of enriched cells isolated from four biologically significant stages of endocrine pancreas development: endoderm before pancreas specification, early pancreatic progenitor cells, endocrine progenitor cells and adult islets of Langerhans. These analyses implicate new signaling pa...

To characterize the endocrine cell types of the pancreas of Rana temporaria, conventional staining, silver impregnation, and immunocytochemical methods for light and electron microscopy have been applied to paraffin, thin and semithin sections, many of them serial pairs. Quantitative data on the frequency and distribution (insular, extrainsular among the exocrine cells, or within the pancreatic...

In the present study, we aimed to determine localization and distribution of entero-endocrine cells in gastrointestinal tract by immunohistochemical methods understand structure glycoproteins elaborated epithelium digestive regions histochemical methods. The nine sparrowhawks were euthanized, tissues removed fixed formalin. sections stained with techniques evaluate enteroendocrine histomorphome...

Neoplasms of the pancreas usually show either ductal, acinar, or endocrine differentiation. Mixed exocrine-endocrine pancreatic neoplasms, in which the endocrine component is significant and comprises one-third to one-half of the tumor tissue, are rare. Truly mixed tumors have to be distinguished from exocrine neoplasms with scattered endocrine cells. In ductal adenocarcinomas, the scattered en...

in the religion of islam, fasting is obligatory for healthy adults during ramadan. millions of muslims around the world practice fasting in this holy month which may cause different metabolic and hormonal changes due to the restrictions in regular caloric intake. this article was aimed to review some possible effects of ramadan fasting on the endocrine system which has a great impact on physiol...

Neurogenin3 (NEUROG3) is a basic helix-loop-helix transcription factor required for development of the endocrine pancreas in mice. In contrast, humans with NEUROG3 mutations are born with endocrine pancreas function, calling into question whether NEUROG3 is required for human endocrine pancreas development. To test this directly, we generated human embryonic stem cell (hESC) lines where both al...
