A number of biomarkers are available for glioma cells, such as mutation of isocitrate dehydrogenase 1 (mIDH1) [7, 8], methylation of MGMT gene (DNA repair enzyme O6-methylguanine-DNA methyltransferase) [9], as well as standard stem cell markers including, but not restricted to, CD133, Musashi-1, Bmi-1, Sox-2 and Nestin [10, 11]. Here, MGMT is linked to central nervous system cancer.
