Fig. 2. Epithelial cell subgroup selection. (A) Epithelial cell cluster grouping under UMAP dimensionality reduction. (B) UMAP dimensionality reduction of epithelial cell clustering displayed by clinical group. (C) Cell group proportions, presented by cell clusters. (D) Overall cell communication of the epithelial subgroup with increased total in invasive prostate cancer and the remaining subgroups. (E) Bubble plot of overall cell communication of the epithelial subgroup with increased numbers in invasive prostate cancer and the remaining subgroups. (F) Number of cell communications of the epithelial subgroup with increased numbers in invasive prostate cancer and the remaining subgroups. (G, H) Cell communication status of each cell type. IS Epi: epithelial cells from clusters 1, 2, 3, and 5, Other Epi: epithelial cells from all other clusters except 1, 2, 3, and 5, UMAP: uniform manifold approximation and projection, NK cell: natural killer cell.
