  • Title: Lateral connections between heart muscle cells as revealed by conventional and high voltage transmission electron microscopy.
    Author: Robinson TF.
    Journal: Cell Tissue Res; 1980; 211(3):353-9. PubMed ID: 7191349.
    Abstract:
    The lateral surfaces of heart muscle cells are interconnected by a varied and extensive network of structures that exist in addition to intercalated discs. Ultrastructural images of this network are vastly improved over those from epoxy-embedded material, particularly for low density components, through the application of a method for removing the embedding matrix from thin or thick sections that are then stereoscopically analyzed with standard or high voltage transmission electron microscopy. The connections include cables, 3-20 nm in diameter, multi-strand cables, 10-40 nm-granules, meshlike mats, and sheets, all extensively interwoven. It is suggested that intercellular connections of varying strength and distribution aid in the integration of mechanical performance of the large population of myocytes during the contractile cycle of the heart.
