Abstract
Recent advances in stimulated emission depletion (STED) microscopy offer an unparalleled avenue to study membrane dynamics of exo- and endocytosis, such as fusion pore opening, pore expansion, constriction, and closure, as well as the membrane transformation from flat-shaped to round-shaped vesicles in real time. Here we depict a method of using the state-of-the-art STED microscopy to image these membrane dynamics in bovine chromaffin cells. This method can potentially be applied to study other membrane structure dynamics in other cell model system.
