Anti-inflammatory cytokine concentration. Concentrations of (A) IL-4, (B) IL-13, (C) IFNα. *Statistically significant differences from the plasmatic concentration (analysis of variance followed by Dunnett’s multiple comparison test, n = 6, α = 0.05). PPP, platelet-poor plasma; PRP1, platelet-rich plasma after the first blood centrifugation step; PRP2, platelet-rich plasma after the second centrifugation step; PRP2-Ca, calcium-activated PRP2; PRP2-Thr, calcium plus human thrombin-activated PRP2.
