Layers of concentric circles, or chains, of glycoproteins separated by infrequent glucose and galactose molecules, protectively surrounding cells of the capillaries of kidney, muscle, retina of the eye, etc.
This is a layer of specialized proteins and connective tissue cells which surround epithelium.
delicate structures comprised in part of type IV collagen, entactin, heparin sulfate proteoglycan and laminin found at the interface of cells and stroma; all epithelia and most endothelial cells are separated from the stroma by continuous basement membranes.
Ground substance composed of fibrous elements, proteins and space-filling molecules. It is characteristically found under the epidermal cells and separates them from the dermal layer.
the thin extracellular layer which attaches the epithelium to the underlying connective tissue. It is made up of a superficial basal lamina and an underlying reticular lamina.
The delicate, microscopically thin layer of connective tissue between the secondary horny and secondary sensitive laminae within the equine hoof. The basement membrane is uniform, smooth and unbroken in healthy hooves, but breaks down and tatters with the onset of laminitis.
Membrane that surrounds the single layer of epithelial cells in capillaries; also called basal lamina.
A thin membranous layer of connective tissue that separates a layer of epithelial cells from the underlying lamina propria.
A layer of filaments and fibers that attach an epithelium to the underlying connective tissue.
this membrane defines the area that contains the contents of the cell. Cells are contained in their proper location by a "curb" called the basement membrane.
An amorphous extracellular layer, which is closely applied to the epithelium. It is composed of three layers; lamina lucida, lamina densa and lamina fibroreticularis, a matrix of Type IV collagen and several glycoproteins.
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.
A thin tissue layer that anchors the cells above it; in the skin, the basement membrane lies between the epidermis and dermis
A thin layer in human skin that separates the epidermis from the dermis. 599
A thin layer of extracellular material that underlies epithelium.
The layer of tissue that cells 'sit' on. If cancer cells from a tumour have broken through the basement membrane, then the cancer can spread and is called 'invasive'.
A layer of cells that separate the epithelial cells and other tissue cells. Cancer invades this membrane and grows into adjacent tissue.
Thin sheet which cells rests upon
A membrane of tissue beneath the epithelium that helps adhere the epithelium to the Bowman's layer or stromal 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, and the reticular lamina is produced by fibroblasts of the underlying connective tissue and contains fibrillar collagen.
