A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a cell in the stomach that releases pepsinogen, gastric lipase and chymosin.[1] The cell stains basophilic upon H&E prep due to the large proportion of rough endoplasmic reticulum in its cytoplasm.

Chief cells release the zymogen (enzyme precursor) pepsinogen when stimulated by a variety of factors including cholinergic activity from the vagus nerve and acidic condition in the stomach. Gastrin and secretin may also act as secretagogues.[2]

It works in conjunction with the parietal cell, which releases gastric acid, converting the pepsinogen into pepsin.
