The basement membrane is formed by a mixture of molecules, including type IV collagen (i.e., the structural protein found in the basement membrane, the lens of the eye, and the cochlea of the ear) primarily and laminin (i.e., a glycoprotein, or protein that contains oligosaccharide chains). 63872. Basement membranes are found anywhere in the body containing both. Basement membranes separate the outer epithelial tissue from endothelial tissue. Immediately below the epidermis is the basement membrane, a specialised structure that lies between the epidermis and dermis.It includes various protein structures linking the basal layer of keratinocytes to the basement membrane (hemidesmosomes) and the basement membrane to the underlying dermis (anchoring fibrils).The basement membrane has an important role in making sure the epidermis . J Cataract Refract Surg. 's' : ''}}. Each glomerulus has two layers of filtration material. This is achieved by cell-matrix adhesions through substrate adhesion molecules (SAMs). Any place you find epithelium cells, which cover the inner and outer portions of glands, organs, and structural tissue, and endothelium tissue, which coats the inside of blood vessels, a basement membrane will be in between to hold the layers together. The skin is composed of three layers: the epidermis, dermis, and hypodermis. Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that line all surfaces of the body.

Contains proteins like laminin, collagen, glycoproteins and proteoglycans. Mimicking the Natural Basement Membrane for Advanced Tissue Engineering. The most notable examples of basement membranes is the glomerular basement membrane of the kidney, by the fusion of the basal lamina from the endothelium of glomerular capillaries and the podocyte basal lamina,[9] and between lung alveoli and pulmonary capillaries, by the fusion of the basal lamina of the lung alveoli and of the basal lamina of the lung capillaries, which is where oxygen and CO2 diffusion occurs (gas exchange). with the second layer, a basement membrane.
