From Wikipedia, the free encyclopedia

A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a cell in the stomach that releases pepsinogen and rennin.

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

[edit] Nomenclature

The terms "chief cell" and "zymogenic cell" are often used without the word "gastric" to name this type of cell. However those terms can also be used to describe other cell types (for example, parathyroid chief cells.)
