Supplementary Fig. S7 from Perivascular NOTCH3⁺ Stem Cells Drive Meningioma Tumorigenesis and Resistance to Radiotherapy

Supplementary Fig. 7. WHO grade 1 meningioma immunofluorescence microscopy for NOTCH3 and the endothelial cell marker VWF. NOTCH3 expression is restricted to the perivascular niche adjacent to endothelial cells in meningiomas with WHO grade 1 histology. SF numbers indicate individual meningiomas. Representative of n=10 WHO grade 1 meningiomas. WHO grade defined using histological criteria. Scale bars, 10µm.
