FIGURE 1.

Ribosomal protein S6 (RPS6) expression in glioma tissues. Representative images of hematoxylin and eosin (HE) and immunohistochemical staining. A, Images showing positive RPS6 immunoreactivity in tumor areas and lesser tumor cells in glioblastoma multiforme (GBM). B, Images showing RPS6 expression in GBM and pilocytic astrocytoma. C, Images showing immunoreactivity of GFAP, MAP2. RPS6, SOX2, Nestin, and Olig2, which are markers of stem and progenitor cells, in GBM tissue containing tumor cells. Scale bars, 100 µm
