IL-8 and VEGF production in lung cancer cell lines. (A). IL-8 protein was measured by ELISA in 48 h conditioned medium of a panel of NSCLC (A549, H460 and MOR/P) and SCLC (H69, H345, H711, GLC19 and Lu165) cell lines. (B). VEGF production was measured by ELISA in the same medium of these cell lines. Each bar is the mean ± SEM of three determinations from three independent experiments.
