Cuboidal epithelial cells are a type of epithelial tissue characterized by their cube-like shape. These cells typically have a central nucleus and are found in various organs, where they play a crucial role in secretion and absorption. They are commonly located in glands, such as the thyroid gland, and in the lining of kidney tubules. This type of epithelial cell is important for maintaining the function of organs. Their structure allows for efficient transport of substances, making them essential in processes like filtration and hormone secretion. Cuboidal epithelial cells contribute to the overall health and functionality of the tissues they comprise.
