Fig. 5From: IL6 secreted by Ewing sarcoma tumor microenvironment confers anti-apoptotic and cell-disseminating paracrine responses in Ewing sarcoma cellsa Detection of IL6 mRNA expression in 7 ES tumor samples using RT-PCR. IFN-γ treated PBMC were used as positive control. 3 out of 7 tumor samples expressed IL6 mRNA. b IL6 mRNA expression in 9 ES cell lines by RT-PCR. IFN-γ treated PBMC were used as positive control. 4 out of 9 cell lines expressed IL6 mRNA Back to article page
