ECL cell activation may be defined as the actions of regulatory factors that stimulate or inhibit histamine synthesis or secretion; the release of chromogranin A and its proteolytic product pancreastatin also are relevant, but histamine is the only product from the ECL cell that directly stimulates acid secretion by the parietal cell.

Then 1 mL of growth medium was added to each well, and the ECL cells were cultured for 48 hours. The ECL cell population was always enriched to over 85%, and sometimes was as high as 95%. All experiments reported here on ECL cells (i.e., calcium imaging, histamine release, and the cells as a Clinical, histological, histochemical and ultrastructural characteristics of eight cases of carcinoid tumors of the non‐antral portion of the stomach are presented. Four cases with multiple polypoid lesions are accompanied by an increased level of gastrin. A normal level of gastrin was present in the other four cases with isolated tumor and a normal component of endocrine cells in the Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells, that aid in the production of gastric acid via the release of histamine.

Type I ECL-cell gastric carcinoids, the most common type, typically do not have clinical symptoms. They are often discovered during endoscopy for reflux, anemia, or other reasons; and are typically multifocal.

Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. Thus, the ECL cell and its main regulator, gastrin, are central in human gastric carcinogenesis, which make new possibilities in prevention, prophylaxis, and treatment of this cancer. ECL cells [ECL cell] [enterochromaffin-like cells] These cells (Pearse et al, 1970) - not to be confused with enterochromaffin cells - constitute more than 30 % of the neuroendocrine cells in the acid-secreting gastric epithelium (Prinz et al, 2003; Chen et al, 1998; Chen et al, 1999; Sundler et al, 1998; Hakanson et al, 1998; Zhao and Chen, 2012).They make up approximately 60-70 % of all Simple hyperplasia is defined as hypertrophied ECL cells occurring singly or in clusters of fewer than 5 cells, arranged in the lower third of the gastric pits. Linear hyperplasia consists of 5 or more ECL cells lining the base of the pits or in the glandular neck region ( Figure 3 , A and B). 7 Nodular hyperplasia is when 5 or more ECL cells form nodules, bounded by a basement membrane Furthermore the ECL cells display immunoreactivity for vesicular monoamine transporter type 2 (VMAT-2), synaptophysin, synaptotagmin III, vesicle-associated membraneprotein-2, cys-teine string protein, synaptosomal-associated protein of25 kDa, syntaxin and Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance.

The ECL cell also contains the endocrine polypeptide chromogranin A (CGA) and CGA-derived  The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid. Do they also operate under nervous  Abstract : Enterochromaffin-like (ECL) and ghrelin cells, in the human gastric mucosa and in gastric endocrine tumours (GETs), were subclassified with respect  Abstract : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach.

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 histaminein response to stimulation by the hormones gastrinand pituitary adenylyl cyclase-activating peptide. The ECL cells are the predominant endocrine cell population in the oxyntic mucosa. They produce histamine, chromogranin A/pancreastatin and an as yet unidentified peptide hormone. They respond to gastrin by the release of secretory products; more long-term responses include adaptation to the gastrin stimulus, hypertrophy and hyperplasia.

ECL cell activation may be defined as the actions of regulatory factors that stimulate or inhibit histamine synthesis or secretion; the release of chromogranin A and its proteolytic product pancreastatin also are relevant, but histamine is the only product from the ECL cell that directly stimulates acid secretion by the parietal cell. ECL-celler svarar på gastrin från G-celler och de frisätter histamin vilket stimulerar parietalcellerna att producera magsaft. Sjukdomar [ redigera | redigera wikitext ] De neuroendokrina stamcellerna som ger upphov till enterokromaffina celler i bronkepitelet kan vara ursprungscellerna till småcellig lungcancer . ECL-cells tumör typ III är sällsynta, vanligen solitära och beter sig malignt, medan ECL-cellstumörer av typ I och II ofta är multipla, små (4-10 mm) och lågmaligna (se ”Benigna ventrikeltumörer”). Ett användbart diagnostiskt verktyg vid misstanke om endokrincellstumör är octreotidscintigrafi. Octreotid, en somatostatinanalog Carcinoider i magslemhinnan utgår från de så kallade ECL-cellerna (enterochromaffin like cells).
