2: High
resolution electron tomography of desmosome cell junction. Electron tomogram of
a 100 nm thin section imaged every 1° from 70° to 70°. The nominal setting of
defocus was 1 micrometer, and the pixel size of the data corresponded to 1 nm. The
ultrastructural composition of the desmosome junction is visualized. Filaments
between electron dense plaques on adjacent cell membranes are observed to span
a gap of ~ 30 nm. Cytoskeletal filaments are observed linking into the electron
dense plaques.
