(b) Vessel co-option. Sleeve of tumor cells around capillaries; CD34, DAB, OM ×400. (c) Id., with several Nestin+ tumor cells; DAB, OM ×200. (d) Mild infiltration. Reactive astrocytes on small vessels; GFAP, DAB, OM ×200; (e) More intense infiltration. Reactive astrocytes on vessels; GFAP, DAB, OM ×200; (f) High infiltration. Reactive astrocytes with end-feet on small vessels; GFAP, DAB, OM ×400. IDH, isocitrate dehydrogenase; DAB, 3,3′-Diaminobenzidine.
