Fig 1. Effect of LPS on cytokine production.

Fig 1

(A) ELISA quantification of IL-6 production in cell supernatants of NM and NP fibroblasts (n = 8 each) pre-incubated with 10% csFBS-supplemented medium with/without 10 μg/ml LPS (Pre-LPS, 24 hours) and then incubated with LPS or 10% FBS-supplemented medium (10% FBS) for 24 hours. *P<.05. (B) Effect of increasing LPS concentrations on 10% FBS-induced IL-6 production (NM and NP, n = 4–5). (C) Effect of LPS (10 μg/ml) on 10% FBS-induced cytokine/chemokine production (NM and NP, n = 5–8). *P<.05, ** P<.01, and ***P<.001 versus medium-treated cells.
