Concentration of IL-6 in different mono-cultures and co-cultures. Significantly higher levels of IL-6 were observed in mono-cultures of non-irradiated FBs compared with irr. FBs. In addition, the increase in IL-6 concentration in co-culture of both groups compared with the matched mono-culture was statistically significant. No significant difference was observed when comparing the two co-culture groups. Data for FaDu mono-culture not shown. *P<0.05. IL-6, interleukin-6; FB, fibroblasts; irr. irradiated.
