Immunohistological images of the spinal cord at three weeks after injury.

<p>Immunohistological images of longitudinal sections of injured spinal cords (A; GFAP, B; vimentin). Over-expressed GFAP and vimentin formed a major component of the glial scar; its astrocyte-rich structure would form a barrier to nerve fiber regeneration. Scale bars represent 200 µm.
