Single-cell contextualization of the six composite programs. (A–D) UMAP, standardized UCell overlays, annotation-resolved profiles and donor-resolved descriptive summaries for 14,368 DLBCL cells from four patients, eight samples and nine retained annotations. Among retained annotations, Stromal/fibrotic scores were highest in monocytes/macrophages. Fibroblast and endothelial annotations were absent, preventing direct testing of stromal-lineage localization. Panel (C) dot size is the within-annotation fraction above the program-specific 75th percentile, not tissue abundance. B-cell-sorted and non-B-cell-sorted samples are both represented. No reannotation, malignant-cell inference or taxonomy validation was performed.
