FN1 was significantly upregulated in GBM cells and T cells (general); APOE was significantly upregulated in GBM cells, CSCs and macrophages; RPL7A was significantly upregulated in GBM cells, CSCs and macrophages; and GSTM2 was significantly upregulated in GBM cells and astrocytes (Supplementary Figure 3A). Here, FN1 is linked to glioblastoma.
