Scale box in millimeters. Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside.
The intracellular vesicle transport. The structural and metabolic stability of a eukaryotic cell depends on the trafficking of material between sub-cellular compartments. Intracellular trafficking requires the formation and correct targeting of small, membrane-bound vesicles.Vesicles are first created from a so-called donor compartment.uestions. Our lab is interested in a number of unresolved issues that concern how transport vesicles are formed and consumed in a living cell. While it is known that removal of a vesicle coat must occur prior to membrane fusion, in many cases, exactly when and how vesicle coats are removed is not well understood.
