Simple cuboidal epithelia are epithelial cells in a single layer of cubelike cells with large, spherical central nuclei. Simple cuboidal epithelia are found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, and parts of the eye and thyroid.
On these surfaces, the cells perform secretion and absorption.
These cells provide protection and may be active (pumping material in or out of the lumen) or passive, depending on the location and cellular specialization.
They are also found in kidney tubules, glandular ducts, ovaries, and the thyroid gland. Simple cuboidal cells are found in single rows with their spherical nuclei in the center of the cells and are directly attached to the basal surface.Simple cuboidal epithelium commonly differentiates to form the secretory and duct portions of glands. They also constitute the germinal epithelium which covers the ovary (but does not contribute to ovum production) and the internal walls of the seminiferous tubules in the male testes. These cells offer some protection and function in absorption and secretion.
