Tumor necrosis factor-alpha (TNFα) inhibition at time of intervertebral disc (IVD) injury prevents intradiscal TNFα upregulation at 6 weeks postsurgery. Representative anti-TNFα immunostained sections for A (annulus fibrosus) and B (nucleus pulposus). C, Quantified TNFα by group. Representative anti-interleukin (IL)-1β immunostained sections for D (annulus fibrosus) and E (nucleus pulposus). F, Quantified IL-1β by group. Green arrows denote immunopositive cells. Scatter plots presents the percentage of immunopositive cells for E (TNFα) and F (IL-1β). Data presented as mean ± SD. *P < .05, **P < .01, #P < .10 by a one-way ANOVA with Tukey’s post hoc
