Cytokine and NGF levels in spinal cord tissue 4 and 16 weeks after fracture. The data displayed represent TNFα (a), IL-1β (b), IL-6 (c), and nerve growth factor (NGF) (d) levels in lumbar spinal cord tissue ipsilateral to fracture at 4 and 16 weeks post fracture. Data are expressed as mean values (pg/mg protein) ± standard error (SE) and analyzed using one-way ANOVA followed by Neuman-Keuls multiple comparison test to compare control and fracture cohorts at different time points. *P < 0.05, **P < 0.01, and ***P < 0.001 versus control; # P < 0.05, ## P < 0.01, and ### P < 0.001 versus fracture at 4 weeks (panels a, c, and d, n = 8 per cohort; panel b, n = 6 per cohort)
