Figure 8.

Human meningioma sample stained with different fluorescent dyes ex vivo. Each row consists of a CLE Z-stack image (A and D), the corresponding 3D volumetric view (B and E), and an H&E-stained histological section for comparison (C and F). Both series of images represent a section of a human meningioma that was stained with AO (upper row) or AF (lower row). Both dyes provide good visualization of cellular structure compared with their histologic counterparts.
