Supplementary Fig. S9 from Perivascular NOTCH3⁺ Stem Cells Drive Meningioma Tumorigenesis and Resistance to Radiotherapy

Supplementary Fig. 9. WHO grade 3 meningioma immunofluorescence microscopy for NOTCH3 and the endothelial cell marker VWF. NOTCH3 is expressed in and out of the perivascular niche, and is adjacent to endothelial cells in the perivascular niche, in meningiomas with WHO grade 3 histology. SF numbers indicate individual meningiomas. Representative of n=10 WHO grade 3 meningiomas. WHO grade defined using histological criteria. Scale bars, 10µm.
