Figure 1. Single-cell RNA clustering. (A) UMAP plot of the distribution of 10 samples, UMAP plot of the distribution of 20 subpopulations, and UMAP plots of the subpopulations after cell annotation. (B) After CNV comment, the proportion and cell number of the subpopulation in each sample, and the UMAP map of malignant cells. (C) Dot plots of the expression of the first 5 marker genes of the subpopulations after CNV annotation. (D) The differential gene enrichment analysis of each subpopulation of cells.
