Epithel wikipedia
WebEpithelial cell adhesion molecule ( EpCAM ), also known as CD326 among other names, is a transmembrane glycoprotein mediating Ca 2+ -independent homotypic cell–cell adhesion in epithelia. [5] EpCAM is also involved in cell signaling, [6] migration, [7] proliferation, and differentiation. [8] WebThe intestinal epithelium is the single cell layer that form the luminal surface (lining) of both the small and large intestine (colon) of the gastrointestinal tract. Composed of simple columnar epithelial cells, it serves two main functions: absorbing useful substances into the body and restricting the entry of harmful substances.
