Abstract : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin
The physiological significance of ECL cells reflects the nature of their products such as histamine, chromogranin A-derived peptides, Reg protein and yet-unknown hormone. 1999-11-01 · enterochromaffin-like (ECL) cells are endocrine cells of the gastric mucosa, constituting ∼1–3% of the fundic epithelial cell volume. ECL cells display typical features of neuroendocrine cells and can be detected by staining with bivalent cations using the Grimelius staining protocol (52, 94). N2 - ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity.

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”).
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.
wild-type (WT) mice were investigated 1997-02-01 The ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine.
ECL cells histologically appear similar to EC cells and are hence named as such. They are however a different cell type and do not possess any serotonin synthesizing mechanisms. [citation needed] Development. In developing chick embryos, EC cells have been found in biopsies of developing GIT tissue before the migration of neural crest cells.

Gastric cancer has reduced prevalence, but poor prognoses. To improve treatment, better knowledge of carcinogenesis and cells of origin should be sought. Stomach cancers are typically localized to one of the three mucosae; cardial, oxyntic and antral. Moreover, not only the stem cell, but the ECL cell may proliferate and give rise to tumours.

ECL cells play a pivotal role in the peripheral regula-tion of acid secretion. The importance of ECL cells was accentuated when hyperplasia of these cells was ob-served under therapy with proton pump inhibitors in humans (17, 41, 57, 79). Antisecretory therapy …
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. Specific functional activation (omeprazole-induced hypergastrinaemia) was used as a tool to Gastric ECL cells and parietal (PC) cells in normal conditions and gastric ECL cells after 24 hrs fasting were purified using a combination of counter-flow elutriation, nycodenz gradient and FACS based on acridine orange labeling of histamine containing vesicles (ECL cells) or autofluorescense (PC cells) to homogeneity. cRNA probes from this purified cell suspensions and from mixed gastric Electrochemiluminescence (ECL) microscopy is successfully applied to image cells, micro-/nano-objects, and electrochemical processes at electrode surfaces.
