Microfilaments

Three fibroblasts in culture were stained with fluorescently-labeled phalloidin, which specifically binds to actin, the protein that makes up microfilaments.  In these cells, microfilaments form stress fibers that form a complex network throughout the cytoplasm to provide support for the cell and its processes.  The filaments outline the position of the nucleus.  Microfilaments are also concentrated beneath the plasma membrane.  800x
