MOESM2 of In situ characterization of stem cells-like biomarkers in meningiomas

Additional file 2: Figure S1. H&E images for different morphological variants and atypical features for meningiomas used in this study. A. Images showing WHO classified morphological features for different meningioma variants. Meningothelial (Jed39_MN) with neoplastic growth of syncytial epithelial cells with indistinct cell borders arranged in whorls; fibroblastic (Jed40_MN) showing spindle cells with indistinct cell boundaries running in fascicle; transitional (Jed38_MN) with ratios of meningothelial to fibroblastic patterns 40:60; psammomatous (Jed43_MN) composed of whorled clusters of spindle cells with numerous psammoma bodies; chordoid (Jed79_MN), Cords of epithelioid cells with focal clear to foamy cytoplasm on myxoid stroma.; rhabdoid (Jed29_MN) showing hypercellular sheets with rhabdoid morphology. B. Tumors with atypical features. Images show patternless growth (sheeting) in Jed72_MN, necrosis and small cells with high nuclear to cytoplasm ratio in Jed58_MN, and brain invasion in Jed13_MN. Magnifications are indicated above images.
