| 释义 | epithelia plural ofepitheliumspecialized Examples of epitheliaepithelia Such epithelia form a specialized structure, termed the cell envelope, located immediately under their plasma membrane which is critically involved in barrier function. Small proline-rich proteins are cross-bridging proteins in the cornified cell envelopes of stratified squamous epithelia. A number of specific transport proteins are located in biliary epithelia, including anion exchangers and water transporters (for a review see ref. 41). As one of the major cell-adhesion systems of epithelia, laminin- integrin interactions have been particularly well characterised in the human gut under normal conditions. There are two main types of primary cancers in the liver, namely, hepatoma derived from hepatocytes and cholangiocarcinoma derived from bile duct epithelia. To determine the function of septate junctions in sea urchin embryos, the permeability characteristics of the embryonic sea urchin epithelia were assessed. This includes formation of polarised epithelia that exhibit microvilli, cilia, well-defined junctions and basolateral membrane domains. Adenovirus-mediated gene transfer transiently corrects the chloride transport defect in nasal epithelia of patients with cystic fibrosis. Tight junctions regulate the barrier to paracellular permeability in chordate epithelia; however, the sea urchin blastula epithelium lacks tight junctions and instead possesses septate junctions. Unlike the epithelia of the reproductive tract, the normal ovarian surface epithelium has only a tenuous attachment to underlying stromal components. Implications for recruitment of inflammatory cells to damaged epithelia. Membrane asymmetry in epithelia: is the tight junction a barrier to diffusion in the plasma membrane? Whether similar interactions between astrocyte-like peripheral glia and epithelia regulate mucosal barrier function is not known. Histozoic parasites in the epithelia of the digestive system of marine fish. The epithelia cells are ciliated, cylindrical, and polarized with three distinct regions.
