Fig 6. Effect of corticosteroids on the release of pro-inflammatory cytokines and MMP9 in LPS pretreated keratocytes.

Fig 6

Keratocytes were treated with 10 μg/ml LPS to induce an inflammatory response. Corticosteroid-LPS groups were added LPS and corticosteroids at the same time to see corticosertoids’ effects on keratocytes under inflammatory condition. The levels of TNF-α (A), IL-6 (B) and IL-1β (C) were evaluated after 48 h in culture. (D)Western blot result and corresponding grey value scanning of MMP9 expression was shown. *p<0.05 versus control group, #p<0.05 versus LPS group (n = 3).
