Recently, we showed that the ECL cells in the oxyntic mucosa of the rat stomach are an important source of circulating pancreastatin, a fragment of chromogranin A. The present study examined how much the ECL cells contribute to the circulating levels of pancreastatin during omeprazole-evoked hypergastrinemia.

THE ENTEROCHROMAFFIN-LIKE (ECL) CELL Physiological and pathophysiological role HELGE L. WALDUM, ARNE K. SANDVIK, UNNI SYVERSEN and EILIV BRENNA Histamine has a central role in the regulation of gastric acid secretion. This histamine is produced by and released from the enterochromaffin-like (ECL) cell which accordingly has a key-regulatory role ECL cell variant (Enterochromaffin-like cell neuroendocrine tumors) Tropic effect from gastrin, related to long standing elevated gastrin levels from gastrinoma or gastric gastrin cells responding to achlorhydria Multiple, polypoid, throughout fundus Usually associated with ECL cell hyperplasia and may be difficult to distinguish from hyperplasia Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise. Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance. In some cases, the anticipated hormone has not yet been identified. Global gene expression analysis of mouse stomach was performed in an attempt to identify the ECL-cell peptide/protein.

“Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine. In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. Enterochromaffin-like or ECL cells are a distinctive type of neuroendocrine cell in the gastric mucosa underlying the epithelium. They are most prevalent in the acid-secreting regions of the stomach. ECL cells synthesize and secrete histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide. The ECL cells are located in the basal part of the gastric pits in the vicinity of parietal cells (Fujiwara et al., 1999) and comprise approximately 40%–50% of all human gastric endocrine cells (Solcia et al., 2000). Histamine in the stomach occurs in endocrine cells (so-called enterochromaffin-like (ECL) cells), mast cells, and neurons.

The results show that several exocytotic proteins, previously identified in neurons, are present in rat stomach ECL cells.

The ECL cell proliferation consisted of a continuum of changes involving diffuse hyperplasia, focal adenomatous hyperplasia, and carcinoid tumor formation at The present study describes the development of lipofuscin in the ECL cells of the rat stomach. These cells produce and secrete histamine in response to gastrin. They are rich in secretory vesicles, which fuse to form vacuoles in hypergastrinaemic rats.

Ageing cells, especially post-mitotic cells, are known to accumulate pigments, i.e. highly electron-dense material, referred to as ceroid or lipofuscin. This material is formed as a consequence of autophagocytosis and peroxidation of the products undergoing degradation. The present study describes the development of lipofuscin in the ECL cells of the rat stomach. These cells produce and

The stomach was surgically resected because of the obstruction associated with ulcer scars. Rat stomach ECL cells were purified by counter-flow elutriation. in the absence or presence of anaesthetic agents in the medium. With the exception of urethane, they inhibited gastrin-evoked histamine secretion dose-dependently, indicating a direct effect on the ECL cells. Anaesthetized rats N2 - The ECL cells constitute the predominant endocrine cell population of the stomach.
