Epithelial tissue: Simple cuboidal epithelium

Example: A simple cuboidal epithelium forms the walls of certain kidney tubules.

The upper photo shows a cross section of kidney tubules. The lower photo shows a longitudinal section of kidney tubules.

The wall of a tubule is composed of a single layer of cuboidal cells (a simple cuboidal epithelium).

In the cross section each tubule appears as a ring of cuboidal cells around a white space (the lumen of the tubule).

In the longitudinal section the lumen of a tubule is indicated by lu. Arrows indicate the edges of this tubule. The darker line of pink at the edges is the basement membrane material of the tubule.
