Membrane-associated particles: increase at sites of pinocytosis demonstrated by freeze-etching.
An increased number of membrane-associated particles has been demonstrated by freeze-etching in areas of pinocytosis in the intestinal smooth muscle cell. A peculiar distribution of the particles is described, which might be closely related to the formation of pinocytotic vesicles (caveolae).
