Ribosomes happen to be basophilic.]. Chief cells of the stomach secrete the digestive enzymes (pepsins) of the stomach and have the typical appearance of serous-secretory epithelial cells. Secretory vesicles (containing pepsinogen) are clearly visible in the apical cytoplasm of chief cells.
One of the important products of gastric juice that is secreted by these cells is pepsin. Pepsin is the chief digestive enzyme in the stomach that breaks down proteins. You can think of pepsin as the 'chief' digestive enzyme in the stomach because it is produced by the chief cells.This can help you remember the term, but I should clarify that pepsin is the active protein-digesting enzyme.The chief cells actually produce pepsinogen (an inactive form of pepsin).ucus that is produced by the epithelial cells of the stomach help protect the lining of the stomach from the corrosive hydrochloric acid and pepsin. If this protective lining fails, it can result in a peptic ulcer, which is a lesion of the mucosa.
