Gliosis after spinal cord injury is different in rats and <i>Gekko japonicus</i>.

<p>Nissl staining (A, B) and glial fibrillary acidic protein (GFAP) immunehistochemical analysis (C, D) of adult geckos (A, C) and adult rats (B, D) after spinal cord transection (n = 6 per group). GFAP staining is shown in panels C and D. GFAP expression in activated astroglia was observed at 1 week post-injury in both adult geckos and rats. In geckos, the GFAP level was weakened at 4 weeks post-injury, while GFAP in adult rats was still strong 4 weeks post-injury.
