  • Title: Structure, function, and pathology of basement membranes.
    Author: Martin GR, Rohrbach DH, Terranova VP, Liotta LA.
    Journal: Monogr Pathol; 1983; 24():16-30. PubMed ID: 6350856.
    Abstract:
    Basement membranes support epithelial and endothelial cells, prevent the passage of proteins, and generate histologically distinct compartments in the body. Basement membranes contain a number of components, only some of which have been isolated and characterized. These include type IV collagen, heparan sulfate proteoglycan, laminin, entactin, and fibronectin. Some components, such as bullous pemphigoid antigen and Goodpasture antigen, are present only in specific tissues, such as the skin or the kidneys. Alterations in basement membranes are associated with various diseases. For example, metastatic cells are able to attach to basement membranes and to degrade them. Such interactions with basement membranes underlie the ability of these cells to penetrate tissues and to spread in the body. In diabetes, basement membranes are thickened but are more porous, which is possibly due to a decreased amount of heparan sulfate proteoglycan. Basement membranes are also the site of immunopathologic disorders.
