Fig. 1From: Cerebrospinal fluid of chronic osteoarthritic patients induced interleukin-6 release in human glial cell-line T98GHigher IL-6 release from OA pain CSF stimulated T98G cells, in the presence of LPS. Concentration of IL-6 release from T98G cells when triggered with 50 μl CSF of either OA-CSF or NP-CSF, in the presence of LPS. Bars are plotted as mean ± standard error of mean (15 patients per group), *p < 0.05 when using Mann Whitney-U testBack to article page
