In total, the CSC markers for ependymoma were expanded (there were numerous markers from single-cell sequencing and, here, we list important ones) to include Vimentin, HES1, PBX1, SOX9, PAX3, Protein c-Fos, ZFP36, LGR5, EGR1, JUN, and ATF3, and differentiation markers of Synaptophysin, O4, Olig1/2, APC, CSPG2, DNAAF1, RSPH1, and CAPS were added [34,35,36]. This evidence concerns the gene FOS and ependymoma.
