Basic Histology -- Mucin-Producing Columnar Epithelium Next Home Back

Very busy secretory epithelia tend to be simple columnar.

Here is epithelium from the lower stomach. It has to produce mucin to keep things moving. Think about the alternative.

Mucin-producing cells often present easy-to-see borders, since the carbohydrate-rich pale-staining mucin contrasts with the protein-rich pink-staining cell surfaces.

This is stomach.
