COL6A1 and central nervous system cancer: To detect the expression patterns of the representative stem cell markers (Nestin, SOX2, STAT3, CD133), ECM markers (FN1, COL1A1, COL6A1, LTBP1), chemokines (CXCL12, CXCL16, CX3CL1, CCL2), and chemokine receptors (CXCR1, CXCR2, CXCR4, CCR5) in gliomas, we examined the RNA sequencing data of gliomas from the GlioVis data portal [36].
