Secretory granules
A mast cell is shown in loose connective tissue. The centrally located nucleus is surrounded by numerous secretory granules, containing heparin, histamine and protease enzymes that function in the inflammatory response. Mast cell granules are located throughout the cytoplasm and thus these cells do not display polarity. Bundles of collagen fibrils are visible around the cell. 10,000x
