(a) ISC from lymph node biopsy of melanoma. Left, H&E staining with pathologic annotation and clustering. Lymphoid tissue occupies two clusters. Right, Spatial heatmaps of select highly-expressed and variable genes. Adapted with permission from Thrane et al., Cancer Research 2018. (b) Left, H&E staining and clustering of ISC spots in squamous cell carcinoma (SCC). Right, Violin plots of TSK scores of individual spots derived from scRNA-seq data (sc-TSK score) for each cluster. One spatial cluster within each sample demonstrates highest sc-TSK score (dotted boxes), highlighting areas occupied by this subpopulation.

Top, H&E staining of a T-lep biopsy; bottom, cell type composition map showing myeloid cells in the granuloma center, while T cells and fibroblasts occupy the periphery. Scale bar: 0.5 mm.
