Nerve fibers in the injured spinal cord of SCI rats with OEC transplantation at 8 weeks after injury.

(A) Representative images of spinal cord sections with silver staining (original magnification 200×, scale bars: 200 µm). Nerve fibers were stained brown–yellow (arrows) in cross sections of the transected ends of the spinal cord. (B) Quantitative results of the positive silver staining signals. Data are expressed as the mean ± SD (n = 6). *P < 0.05 (unpaired t-test). OEC: Olfactory ensheathing cell; SCI: spinal cord injury.
