【医学英语课堂】
A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a cell in the stomach that releases pepsinogen and gastric lipase and is the cell responsible for secretion of chymosin in ruminants.
The cell stains basophilic upon H&E prep due to the large proportion of rough endoplasmic reticulum in its cytoplasm.
Gastric chief cells are generally located deep in the mucosal layer of the stomach lining.
