Figure Legend Snippet: Persistent IL6 and CXCL8 production is limited to a small subpopulation of cells. A, Uniform Manifold Approximation and Projection (UMAP) of tumor cells subsetted from coculture demonstrating that IL6 and CXCL8 expression is limited to a single cluster of cells. B and C, IF of osteosarcoma cells stimulated with IL1α (72 hours) and stained for IL6 (green) and DAPI (blue). Scale bar, 50 µm. The percentage of IL6+ cells was quantified in n = 3 experiments, 100 cells/experiment.
