Effects of OEC transplantation on GFAP immunopositivity in the injured spinal cord of rats.

(A) GFAP immunopositivity in the injured area was detected using immunohistochemistry (original magnification 200×; scale bar: 200 µm). GFAP was highly expressed in both the SCI group and the OEC transplantation group. Arrows indicate GFAP-positive cells. (B) Quantitative analysis of GFAP immunopositivity. GFAP immunopositivity in the OEC transplantation group was significantly lower than that in the SCI group at 2 and 4 weeks after SCI. Data are expressed as the mean ± SD (n = 6). *P < 0.05 (unpaired t-test). GFAP: Glial fibrillary acidic protein; OEC: olfactory ensheathing cell; SCI: spinal cord injury.
