Although both low‐grade and high‐grade tumors were shown to express Nestin in a different study, the majority of gliomas with high levels of Nestin expression were high‐grade gliomas, including glioblastomas, anaplastic oligodendrogliomas, anaplastic astrocytomas, and anaplastic oligoastrocytomas.45 This evidence concerns the gene NES and anaplastic oligodendroglioma.
