Figure 3. Single cell analysis was performed on two datasets, GSE121636 and GSE171306. 24 clusters were identified using the UMAP method, and 14 cell types were identified, including lymphocytes (CD8+ T cells, B cells, NK cells, and CD4+ T cells), myeloid cells (monocytes, macrophages, neutrophils, DC cells, and mast cells), and other cells (endothelial cells, epithelial cells, plasma cells, and stem cells) (A-1 and A-2). An enrichment analysis for the cell components (A-3) was provided. The plots of cell components in the datasets of GSE121636 (A-4) and GSE171306 (A-5) were showed, respectively. The expression of CXCL genes was analyzed in lymphocyte and myeloid cells (B, C), and the correlation between CXCL genes and cell components was analyzed in a pan-cancer dataset, including CXCL genes and B cell (D-1), CXCL13 and T cell (D-2), CXCL genes and Macrophage (D-3), and CXCL genes and Neutrophil (D-4).
