Emerging erythroid cells subpopulations display distinct transcriptional programs. (A) UMAP visualization of the 9 initial clusters of emerging erythroid cells in the pooled scRNA-seq data. (B) UMAP visualization of the 5 reclustered groups in the emerging erythroid cells in the pooled scRNA-seq data. (C) Heat map showing the expression levels of DEGs of single cells of the 9 initial clusters. (D) Heat map showing the average expression levels of DEGs of single cells from group 1 to group 5, as well as 3 individual DEGs from group 2. (E) Dot plot demonstrating the enrichment analysis (GO biological processes) of DEGs from groups_1, 3, 4, and 5, respectively. (F) UMAP visualization of the selected gene expression levels among various groups in emerging erythroid cells, with group 2 highlighted in ovals. (G) Violin plots comparing the differences in selected gene expression levels among various groups in emerging erythroid cells. Adj., adjusted.
