Figure 4. (A)–(D) Enrichment analysis of monocytes. (A) and (B) show bubble and bar charts for enrichment analysis of GO. (C) and (D) show bubble and bar charts for enrichment analysis of KEGG. GO consists of three parts: biological process (BP), molecular functions (MF), cellular components (CC). The length of the bar represents the level of the adjusted P-value (-log10(FDR)), and the longer the bar, the more significant it is. The size of the point represents the number of genes, and the color represents the adjusted P-value (FDR). (E)–(H) Enrichment analysis of HSCs. (E) and (F) show bubble and bar charts for enrichment analysis of GO. (G) and (H) show bubble and bar charts for enrichment analysis of KEGG.
