Figure 7From: Epidermal growth factor receptor inhibitor ameliorates excessive astrogliosis and improves the regeneration microenvironment and functional recovery in adult rats following spinal cord injury PD168393 promoted survival of ventral horn (VH) motor neurons after spinal cord injury (SCI). Representative transverse cresyl violet eosin stained sections of four weeks post-SCI at the epicenter and in 1 mm increments rostral and caudal to the epicenter. Epicenter sections are indicated by arrows. Scale bar = 1 mm (A). Representative photomicrographs from four weeks post-SCI showing cresyl violet eosin stained VH neurons at 4 mm rostral to the injury epicenter. Scale bar = 50 μm (B). Graphical representation showing no statistically significant difference in lesion cavity volume following treatment (n = 5) (C). Comparison of VH neurons among different groups at various distances from the injury epicenter (0) as well as 1 to 4 mm rostral (r) and caudal (c) to it (D) (n = 5, *P < 0.05).Back to article page
