From: Catabolic cytokine expression in degenerate and herniated human intervertebral discs: IL-1β and TNFα expression profile

Figure 3

Number of cells displaying immunopositivity for IL-1β, tumour necrosis factor (TNF)α and their receptors in human human intervertebral discs. The percentage of cells with immunopositivity is given for IL-1β, IL-1RI, TNFα and TNF RI in the (a) nucleus pulposus, (b) inner annulus fibrosus and (c) outer annulus fibrosus of non-degenerate, degenerate and herniated discs (n = 39). Data are presented as means ± 2 standard error (as a representative of 95% confidence interval). *P < 0.05.
