A peg cell is a non-ciliated epithelial secretory cell within the uterine tube (oviduct or fallopian tube). [1] These cells represent one of three epithelial cell types found within the normal fallopian tube epithelium and only make up around 10% of the total number of cells. The other two cell types are ciliated columnar and intercalary cells. [1]
Zollinger–Ellison syndrome (Z-E syndrome) is a rare disease in which tumors cause the stomach to produce too much acid, resulting in peptic ulcers. Symptoms include abdominal pain and diarrhea . The syndrome is caused by the formation of a gastrinoma , a neuroendocrine tumor that secretes a hormone called gastrin . [ 2 ]
Gastrin is secreted by the G cells.G cells are primarily found in the pyloric antrum but can also be found in the duodenum and the pancreas. [12] The primary function of gastrin is to induce the release of hydrochloric acid (HCl) from the parietal cells located in the fundus of the stomach.
Small intestine, pancreas: Inhibits insulin secretion Galanin: Enteric nerves: Ghrelin: Stomach: Stimulates appetite, increases gastric emptying Glucagon-like peptide 1: Pancreas, ileum: Increases insulin secretion Glucagon-like peptide 2: Ileum, colon: Enterocyte-specific growth hormone Growth factors: Throughout the gut: Cell proliferation ...
The histopathologic features of pancreatic acinar metaplasia are: (1) the presence of cell clusters that resembles a many-lobed "berry" (an acinus), with (2) cells that are histomorphologically identical to the glands of the exocrine pancreas.

Enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses.
A G cell or gastrin cell is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells . G cells are found deep within the pyloric glands of the stomach antrum , and occasionally in the pancreas [ 1 ] and duodenum .
