Abstract
AbstractAcinar serous granules in specimens of human submaxillary gland fixed with aldehydes followed by osmium were examined in the electron microscope. Typical mature granules had a tripartite substructure: (1) an eccentrically placed dense spherule; (2) material of intermediate density adherent to the inner aspect of the granule membrane in the form of a crescent; and (3) a less dense, homogeneously fibrillo‐granular matrix. The dense spherules appeared within expanded Golgi saccules; other granule constituents apparently were of secondary acquisition. A few cells contained atypical serous granules in which material of intermediate density was disposed in random loops, whorls, and striae. Such granules usually lacked dense spherules. It is postulated that the two morphologically distinct types of granules represent separate classes of serous secretory products.
