Figure 22

Montage of goldfish optic nerve from just behind the eye (extreme left) to optic tract recess (right), to illustrate the manipulability of the tissue. There are three distinct areas of cells stained for S100. The central area contains Schwann cells that are the result of a lesion 180 days old. To the left is a younger lesion, 90 days old, that is also packed with Schwann cells. On either side of the Schwann cells areas are regions of CNS. Remyelination commences synchronously throughout the nerve. Beyond the dashed line (→) are cell bodies of astrocytes at the optic tract recess.
