Facilitates diffusion of different substances between cells and blood vessels

                   Acts as an efficient barrier to the spread of pathogens
                   Bacteria can hydrolyze hyaluronic acid and reduce barrier viscosity
                   Contains several adhesive glycoproteins, such as fibronectin, that bind cells
                   to fibers
                   Integrin protein binds collagen fibers to actin

                   Laminin is a component of basement membrane and binds epithelial cells to
                   basal lamina
