Figure 3.

Vesicle-bound aggregations may be released from cells by exocytosis. Examples from two different cells (a–g) reveal that Hirano bodies and/or Hirano body fragments appear to undergo exocytosis. The arrowheads indicate the site of these events and the images at higher magnification allow the periodicity of the components to be more clearly resolved. (g) The same aggregation viewed in (d–f) from several serial sections later appears to be well outside of the cell. Scale bar = 1 μm (a and c), 500 nm (b, e and g), 100 nm (c and f).
