Figure Lengend Snippet: (A) Daily and (B) cumulative NO release from TNFαα‐stimulated IVD explants alone and co‐cultured with M1 macrophages (IVD + TNFα: n = 3, IVD + TNFα + M1: n = 6). Cumulative concentrations of (C) TNFα, (D) IL‐6, (E) IL‐13, and (F) CCL2 in media supernatants from M1 macrophage‐IVD explant co‐culture in TNFα ( n = 3). (G) Daily and (H) cumulative NO release from TNFα‐stimulated IVD explants alone and co‐cultured with M2 macrophages (IVD + TNFα: n = 3, IVD + TNFα + M2: n = 6). Cumulative concentrations of (I) TNFα, (J) IL‐6, (K) IL‐13, and (L) CCL2 in media supernatants from M2 macrophage‐IVD explant co‐culture in TNFα ( n = 3; Black * p < 0.05 IVD + TNFα significantly different from IVD + TNFα + M1/M2 within timepoint, colored * p < 0.05 Group of corresponding color significantly different between timepoints, ^ p < 0.05 IVD + TNFα + M1/M2 signficantly different from TNFα + M1/M2, + p < 0.05 IVD + TNFα significantly different from TNFα + M1/M2).
Article Snippet: Production of inflammatory cytokines and chemokines was also evaluated using the Rat CCL2 DuoSet ELISA (R&D Systems, Cat#. DY3144‐05) and the LEGENDPlex Rat Th Cytokine Panel V02 (BioLegend, Cat#. 741220) multiplex assay containing 13 analytes: TNFα, IL‐6, IL‐13, IFNγ, IL‐17A, IL‐17F, IL‐5, IL‐2, IL‐4, IL‐10, IL‐22, GM‐CSF, and IL‐9.
