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.
There are four types of cells in the stomach: 1  Parietal cells: Produce hydrochloric acid and intrinsic factor. 2  Gastric chief cells: Produce pepsinogen. 3  Chief cells are mainly found in the body of stomach, which is the middle or superior anatomic portion of the stomach. It is produced by the stomach cells called chief cells in its inactive form pepsinogen, which is a zymogen. 2  Pepsinogen is then activated by the stomach acid into its active form, pepsin. 3  Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids.
