Cell Communication – An Overview

Cell communication is the driving force that enables the development and functioning of all multicellular organisms. From reproduction and embryogenesis to cellular and tissular homeostasis in the adult, the control of metabolism and general physiology, as well as the dysregulations in pathological processes, cell communication is germane to all aspects of eukaryotic life. This section covers cell signaling in a holistic way by detailing the principal extracellular and intracellular mechanisms underlying cell communication.
