The stomach is an ideal organ to study because the gastric juice kills most of the swallowed microbes and, thus, creates rather similar milieu among individuals. ECL cells expressed this receptor, whereas gastrin receptor immunoreactivity on parietal cells was ambiguous [30]. In any way, the ECL cell can proliferate and develop into neoplasia, and gastrin has a positive trophic e ect on this cell through its gastrin receptor. 3. Background & Aims: Gastrin stimulation of the type 2 cholecystokinin (CCK2) receptor results in ECL cell proliferation and histamine secretion. This report describes the effects of targeted disruption of the CCK2 receptor gene on ECL cell morphology and function.

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.

ECL cells are histamine-containing endocrine/paracrine cells in the oxyntic mucosa of the stomach. They play a key role in the control of acid secretion because of their ability to secrete histamine, which stimulates adjacent acid-producing cells (for reviews see Håkanson et al.1994, 1998). The ECL cell hyperplasia and neoplasia has been reported in patients with atrophic gastritis, in patients with sporadic gastrinoma 8 and patients with gastrinoma as a part of MEN I. 9 Long‐term PPI treatment is another condition with gastric hypo/anacidity and secondary hypergastrinemia. 6 It has been known that treatment/dosing with efficient inhibitors of acid secretion causes ECL cell ECL MOVIL, Ecatepec de Morelos.

Anne E. Bishop, Enterochromaffin-like (ECL) cells, in contrast to EC cells, are Enterochromaffin-Like Cells. The 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. 6 rows ECL cells also secrete pancreastatin and probably are the source of one or more other peptide hormones and growth factors. ECL cells are readily identified in histologic sections stained by silver impregnation. Longer term stimulation of ECL cells by gastrin also stimulates significant proliferation of ECL cells.
