Histology of H&E (top) and Masson’s trichrome (bottom)-stained HSA tumor sections. H&E staining shows that collagen bundles are surrounded by neoplastic endothelial cells and appear to form “inside out” blood vessels (a and b). Trichrome-stained HSA sections (c and d) show collagen bundles (blue staining) in vascular regions of the tumor are surrounded by endothelial cells. a and c: low magnification, (b and d): high magnification. Scale bars represent 50 μm in a-d, and 10 μm in insets in b and d. HSA (B783) FFPE sections were stained
