Fig. 3. Electron micrographs of intracytoplasmic desmosomes from mouse skin wounds. Images within 10 cell diameters (A-D) or 40-50 cell diameters from the wound edge (E,F), showing intracytoplasmic desmosomes (blue arrows). B is an enlargement of the area enclosed within the square in A. Note the absence of desmosomes from the cell surface membranes in all images. Black arrows indicate possible membrane fragments associated with some desmosomes. Bars, 100 nm.
