Secretion of seven cyto/chemokines into the basolateral medium. Levels of GRO (A), IL-8 (B), IP-10 (C), MIP-1β (D), RANTES (E), SDF-1 (F), and MCP-1 (G) were measured on days 1–4 after exposure to various doses of CSE (0, 5, 10, 20, or 50 μg/ml). Data are plotted as means of triplicate measurements, and the error bars show standard errors. *Significantly different from untreated controls on each exposure day (p <  0.05, one-way ANOVA with Dunnett’s test). LOQ, limit of quantitation.
