NettetIn line with this aim, epithelial and endothelial cells have been grown on filters for more than three decades. Growing such cells on permeable support allows for nutrient uptake via the basolateral membrane of tight epithelial monolayers, from a medium reservoir underneath the filter. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal.
