Figure 1. TNF-α is increased in degenerative IVD and peripheral serum.

Figure 1

(A-B) Expression of TNF-α in the IVD tissues of normal people and patients with IDD was detected by the immunohistochemical staining. (C) Mean density of the normal group and IDD group based on the result of immunohistochemical staining. (D) The different serum level of TNF-α in the normal people (N=10) and the patients with IDD (N=40), Scale bar=100 um. The values are mean ± SEM of at least 3 independent experiments; ***P<0.001.
