Figure 2 (A) Interleukin 8 (IL8) secretion of CCD‐18Co cells incubated with conditioned medium (cond med) and lysates of HT‐29 and CaCo‐2 cells for 24 h. Unconditioned medium was used as control. Incubation with the pellet of HT‐29 cells strongly induced IL8 secretion. Data represent three different experiments and are given as mean (SD). *p<0.01 versus control; NS, not significant. (B): IL8 secretion of primary colonic lamina propia fibroblasts (CLPFs) incubated with control medium and with conditioned medium and lysates of HT‐29 and CaCo‐2 cells for 24 h. The stimulation with lysates of HT‐29 and CaCo‐2 induced IL8 secretion in CLPF. Data represent three different experiments and are given as mean (SD). NS, not significant versus control.
