ep·i·the·li·al cell

one of the many varieties of cells that form epithelium.

epithelial cell

any one of several cells arranged in one or more layers that form part of a covering or lining of a body surface. The cells usually adhere to one other along their edges and surfaces. One surface is free, and the other rests on a noncellular basement membrane. See also epithelial tissue.

epithelial cell

Any of the cells forming the cellular sheets that cover surfaces, both inside and outside the body. Epithelial cells are closely packed and take on polyhedral shapes, from tall (columnar) through squat (cuboidal) to flat (squamous). Epithelial cells adhere strongly to one another, and one of their surfaces -- the basal surface -- sticks firmly to a thin extracellular film of fibrils called a basal lamina. A sheet of epithelial cells derived from embryonic epithelia (the ectoderm or the endoderm) is called an epithelium. See: epithelium
