Abstract

Cytoplasmic microfilaments are regular constituents of the cortical cytoplasm of rat mast cells. Heavy meromyosin binding to the microfilaments in glycerinated mast cells indicates that they represent actin filaments. Many of the actin filaments were found to be attached to spots of increased density of the plasma membrane. The actin filaments, possibly as part of an actomyosin system, may be involved in exocytosis of mast cell granules.
