Definition : Cuboidal epithelial cells have a cube-like shape and appear square in cross-section. The cell nucleus is large, spherical and is in the centre of the cell.

Cuboidal epithelium is commonly found in secretive tissue such as the exocrine glands, or in absorptive tissue such as the pancreas, the lining of the kidney tubules as well as in the ducts of the glands.

The germinal epithelium that covers the female ovary, and the germinal epithelium that lines the walls of the seminferous tubules in the testes are also of the cuboidal type.

Cuboidal cells provide protection and may be active in pumping material in or out of the lumen, or passive depending on their location and specialisation.

Simple cuboidal epithelium commonly differentiates to form the secretory and duct portions of glands.

Stratified cuboidal epithelium protects areas such as the ducts of sweat glands, mammary glands, and salivary glands.
