What do EC cells in the stomach produce?

EC cells in the stomach primarily produce hormones, specifically serotonin and chromogranin. These cells are part of the enteroendocrine cell family and are found in the gastric mucosa. Serotonin plays a key role in regulating gastrointestinal motility and can influence gastric secretions and blood flow to the stomach. The release of these compounds contributes to the complex regulation of digestive processes.

In contrast, pepsinogen is produced by the chief cells, somatostatin is secreted by D cells, and intrinsic factor, which is essential for vitamin B12 absorption, is produced by parietal cells. Each of these other cell types has distinct functions within the gastric environment, further illustrating the specialized roles that different cell types play in maintaining digestive health.
