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 and duodenum . The vagus nerve innervates the G cells . Gastrin - releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto G cells during parasympathetic stimulation . The peptide hormone bombesin also stimulates gastrin from G cells . Gastrin - releasing peptide, as well as the presence of amino acids in the stomach, stimulates the release of gastrin from the G cells . Gastrin stimulates enterochromaffin - like cells to secrete histamine . Gastrin also targets parietal cells by increasing the amount of histamine and the direct stimulation by gastrin, causing the parietal cells to increase HCl secretion in the stomach . </P> <P> G cells have a distinctive microscopic appearance that allows one to separate them from other cells in the gastric antrum; their nuclei are centrally located in the cell . They are found in the middle portion of the gastric glands . </P>

Where are g cells found in the stomach
