(2)Oligodendrocyte precursor-like (OPC-like): predominantly localize in the tumor core; show overexpression of OLIG2, platelet-derived growth factor receptor (PDGFR) alpha (PDGFRA), NG2, and SOX10, resembling oligodendrocyte progenitor cells; and are enriched at the infiltrative margin. This evidence concerns the gene PDGFRA and neoplasm.
