  • Title: The distribution of actin in cultured ovarian granulosa cells.
    Author: Batten BE, Anderson E.
    Journal: Am J Anat; 1983 Jul; 167(3):395-404. PubMed ID: 6410895.
    Abstract:
    Ovarian granulosa cells grown on glass coverslips were split by a "sandwich" technique. Using this technique we describe a complex filamentous network in the cytoplasm of cultured granulosa cells that was composed of a branching and anastomosing lattice of filaments 20-40 nm in diameter. Since filament identification is impossible on the basis of size, split cells were decorated with S-1 fragments of rabbit skeletal muscle myosin. It was readily apparent that the major constituent of the filamentous lattice was actin. Actin was organized in large bundles in which individual filaments were longitudinally aligned. Actin was also observed organized in a loose network throughout the remainder of the cytoplasm. Actin appeared to be intimately associated with organelle and plasma membranes. Coated pits were also a site of actin-filament interaction. Filament polarity was generally away from the membrane with which filaments were associated.
