Figure 4: Expression of pro- and anti-inflammatory cytokines in splenocytes within 14 days after SCI. (A–G) A mouse cytokine array was used to measure the dynamic expression levels of inflammatory cytokines, including TNF-α, IL-4, IFN-γ, IL-6, CXCL10, TGF-β, and M-CSF in the culture supernatant of splenocytes after stimulation. Data are expressed as the mean ± SEM (n = 6; one-way analysis of variance followed by Tukey's post hoc test). *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. CXCL10: C-X-C motif chemokine ligand 10; IFN-γ: interferon-γ; IL-4: interleukin 4; IL-6: interleukin 6; M-CSF: macrophage colony-stimulating factor; SCI: spinal cord injury; TGF: transforming growth factor.
