For this analysis we treated A172 glioma cells and the HF2354 GSCs with IL-6 and found that this treatment upregulated the expression of the mesenchymal markers vimentin and FN in these cells (Fig. 7A), increased cell migration of the A172 cells and of the GSCs, HF2354 and HF2359 (Fig. 7C). Here, VIM is linked to glioma.
