In general, the term vesicle refers to a small sac or cyst that contains fluid or gas. In cell biology, vesicle refers to the bubble-like membranous structure that stores and transports cellular products, and digests metabolic wastes within the cell. The cell forms vesicles during exocytosis, endocytosis, and intracellular transport. Vesicles may be produced artificially and are referred to as lyposomes. Some of their functions are associated with metabolism, transport, storage of food and enzymes, and buoyancy. There are different forms of vesicles: vacuoles, lysosomes, transport vesicles, secretory vesicles (e.g. synaptic vesicles), extracellular vesicles (e.g. exosomes, microvesicle, etc.), and gas vesicles. Word origin: Latin vÄsÄ«cula, diminutive of vÄsÄ«ca, bladder, blister See also: organelle; Related term(s): Neurotransmitter vesicle; Biliary vesicle
