Chief Cell

Remember that song in Peter Pan? "What made the red man red"? Yeah, sorta racist.

Chief cells are found in the body of the stomach and are chiefly (hah?!) responsible for the secretion of pepsinogen, the zymogen to pepsin. The nucleus is located basally along with basophilic rough endoplasmic reticulum and on the apical surface you can see the graunules filled with eosinophilic pepsinogen.
