Figure Lengend Snippet: Deep spatial profiling of human palatine tonsil tissues. (A) Hematoxylin and eosin (H&E) staining after 92 MICS cycles, including the marked epithelium, germinal center (GC), and T cell zone of the lymphoid follicle. MICS DAPI and stroma staining depicting the composition and structure of the tonsil. Markers: Collagen III, collagen IV, fibronectin (all extracellular matrix (ECM), cytokeratin (epithelium), podoplanin (lymphatic vessels), CD105/SM Actin (blood vessels). (B) Immune cell content of a human palatine tonsil comprising T cells (CD3), B cells (CD19/CD20), plasma cells (PCs) (CD38/CD138), NK cells (CD56), granulocytes (CD15/CD66b), mast cells (CD117), macrophages (MΦ) (CD163/CD169/CD206), myeloid dendritic cells (mDCs) (CD11c), and plasmacytoid dendritic cells (pDCs) (CD123). (C) Detailed view on the T cell zone, mainly composed of CD4 + helper T cells (T h ) and CD8 + cytotoxic T cells (T c ), mDCs (CD11c), and PCs (CD38/CD138). (D) Detailed view on the GC-mantle zone border, showing different B cells (CD11b, CD21, CD22), mDCs (CD11c), and PCs (CD38/CD138). (E) Cell annotations of three different tonsil samples plus respective bar graphs of gated cell populations, comparing the cell content between the three tonsil samples. Depicted markers and annotated cell types as indicated by the color code. ROI sizes: 976 x 640 µm, zoomed-in subregions in (C, D) : 334 µm x 219 µm. Scale bar: 100 µm.
