Figure Lengend Snippet: Evaluation of TLS maturation and prognostic analysis of PSCC patients. A UMAP plot of the cell types identified in PSCC through spatial transcriptomic sequencing, depicting 7 distinct cell populations. B Dot plot displaying the expression of cell type-specific markers. The dot size represents the proportion of cells expressing the marker, while the colour intensity indicates the mean expression level. C Regions with AUCell scores for mTLS genes ( BCL6 , AICDA , CD38 , ICOS , CXCR5 , CXCL13 , and CD21 ) above the median were defined as mTLSs, whereas those below the median were classified as iTLSs. D Spatial visualization of AUCell scores for mTLS genes, where warmer colours indicate higher scores. E Spatial distribution of iTLSs (green) and mTLSs (orange) across different regions of PSCC tissues. F Representative images H&E staining and immunofluorescence staining for CD20 (green) and CD21 (red) in iTLSs and mTLSs. G GO enrichment analysis of upregulated genes in mTLS. Darker colours denote more significant enrichment of the pathway, and larger dots represent a greater number of genes involved. H Kaplan–Meier survival curves showing that patients with mTLSs experienced significantly longer overall survival than those with iTLSs, as determined using ssGSEA ( P < 0.05)
