The basement membrane is a thin sheet of fibers that underlies the epithelium which lines the cavities and surfaces of organs including skin, or the endothelium which lines the interior surface of blood vessels. The name is somewhat misleading in that the basement membrane is not actually a membrane; rather, it is a matrix beneath any epithelium. ...

a thin sheet of proteins held together by type IV collagen. On this sheet epithelial cells attach with hemi-desmosomes. All epithelia, whether simple cuboidal cells such as found in the salivary glands, or endothelial cells lining capillaries or thick stratified squamous epithelia of the skin, are all anchored to a basement membrane.

a sheet of amorphous extracellular material upon which the basal surfaces of epithelial cells rest; it is also associated with muscle cells, Schwann cells, fat cells, and capillaries, interposed between the cellular elements and the underlying connective tissue. It comprises two layers, the basal lamina and the reticular ...

A specialized, sheet-like structure of the extracellular matrix that separates cells from the surrounding connective tissue, and thereby serves as a boundary of a tissue. The basement membrane must be broken down in order for cancer cells to invade surrounding tissue.

Extracellular matrix characteristically found under epithelial cells. There are two distinct layers: the basal lamina, immediately adjacent to the cells, is a product of the epithelial cells themselves and contains collagen type IV; the reticular lamina is produced by fibroblasts of the underlying connective tissue and contains fibrillar collagen.

Type: Term Definitions: 1. an amorphous extracellular layer closely applied to the basal surface of epithelium and also investing muscle cells, fat cells, and Schwann cells; thought to be a selective filter and to serve both structural and morphogenetic functions; it is composed of three successive layers (lamina lucida, lamina densa, and lamina fi...

Basement membrane: A thin membrane upon which is posed a single layer of cells. The basement membrane is made up of proteins held together by type IV collagen. The epithelial cells are anchored with hemidesmosome to the basement membrane. The end result resembles a layer of tiles attached to a thin sheet.
