Photomicrographs of CV-stained spinal cord sections at different times post-SCI and different distances from the epicenter. Following a laminectomy, the rat spinal cords were injured (50 g.cm), the injured cords were removed at different times post-SCI and processed for CV staining. The upper panel shows surviving cells in CV-stained sections at 1 mm caudal from the epicenter removed at 1 and 24 h post-SCI. The lower panel shows surviving cells in CV-stained sections at 0 and 2 mm caudal from the epicenter removed at 24 h post-SCI. A-C: Lower magnification, D-F: higher magnification of A-C. Scale bar: A-C, 100 μm, D-F, 50 μm.
