WebThe purpose of tight junctions is to keep liquid from escaping between cells, allowing a layer of cells (for instance, those lining an organ) to act as an impermeable barrier. For example, the tight junctions between the epithelial cells lining your bladder prevent urine from leaking out into the extracellular space. Desmosomes WebOne cell surface receptor, syndecan-4, has been shown to regulate focal adhesions, junctions that form at the ends of microfilament bundles in response to matrix components such as fibronectin. Recently it has been shown that signaling emanating from this proteoglycan receptor includes regulation of Rho family GTPases and cytosolic calcium.
