In a multicellular organism, cells have to communicate with each other so that they can coordinate their activities. Cellular communication is usually mediated by extracellular messenger molecules that are recognized by receptors present on the surface of target cells. Binding of a messenger molecule to a receptor results in biochemical changes within the cell that make it possible for the cell to respond to the incoming message. Many different processes, such as cell division, differentiation, cell migration, metabolism, and cell death, are regulated in response to extracellular messenger molecules.
