Pepsinogen is released from mucous cells and chief cells.


Pepsinogen is an inactive zymogen used in digestion. It is secreted into the gastric juice by both mucous and chief cells. It is then activated by the stomach acid and becomes pepsin, an active protease.

Its purpose is mainly to aid in the stomach's initiation of digestion.
