By ultrastructure, human skin mast cell granules exhibit amorphous regions situated next to crystalline regions with scroll, lamellar, and grating/lattice-like configurations. The composition and function of these structural domains is unknown. These granules also contain large amounts of three serine proteinases termed tryptase, chymase, and cathepsin G. In this study, subgranular proteinase distribution is correlated with granule ultrastructure.
