Fig. 5From: High-magnitude compression accelerates the premature senescence of nucleus pulposus cells via the p38 MAPK-ROS pathwayAnalysis of p38 MAPK activity from nucleus pulposus (NP) cells in scaffold culture. 20% deformation compression significantly increased p38 MAPK activity and treatment with the ROS scavenger NAC had no significant effect on 20% deformation compression-induced p38 MAPK pathway activation. Data are expressed as the mean ± SD (n = 3). *Indicates a significant difference (p < 0.05) between two groups; #indicates a significant difference (p < 0.05) compared with the control groupBack to article page
