Figure 8.

Expression of CHO1F′ inhibits the organization of electron dense midbody matrix. Thin section electron micrographs show a control cell (A and B) and a cell expressing CHO1F′ (C and D) at the late stage of cell division. Both cells are seen at low (A and C) and high (B and D) magnifications. Although the electron dense midbody matrix can be easily detected in the intercellular bridge connecting two control cells (arrows in A and B), the electron-dense structure is completely disorganized in the cell expressing CHO1F′. Bars: A and C, 5 μm; B and D, 0.5 μm.
