Extended Data Fig. 5: Biopsy results obtained from the oligodendroglioma patients.

a, Hematoxylin and Eosin (H&E) histology result from the grade-II oligodendroglioma patient (scale bar = 50 µm). b, H&E histology result from the grade-III oligodendroglioma patient, with the same magnification factor as in a. Noticeably increased number of cells can be seen in the grade-III oligodendroglioma patient result. Histological analysis was performed once for each patient. c, Cell density counting results for these two oligodendroglioma patients. More than a factor of two increase in cell density can be found for the grade-III oligodendroglioma patient.
