Dictyostelium cells (see left column) containing Hirano bodies that contain actin filaments (middle column) were stained with a panel of antibodies to determine the presence of other selected cytoskeletal proteins (right column). Dictyostelium Hirano bodies contain actin, cofilin (C), myosin II (B), and alpha-actinin (D), but not tubulin (A), ABP 120 (E), or EF 1-alpha (F).
