Single-cell RNA-sequencing combined with bulk RNA-sequencing analysis of peripheral blood reveals the characteristics and key immune cell genes of ulcerative colitis

Figure 2 Clustering of peripheral blood mononuclear cell samples from ulcerative colitis patients. A: Distribution of peripheral blood mononuclear cells. The dots represent cells, and the colors represent the samples; B: The P value corresponds to each principal component (PC), and the PC was determined based on the P value; C: According to the important components identified via PCA, the cells were divided into 17 clusters using the tSNE algorithm; D: Heatmap of the top 10 characteristic genes of each cluster.
