Heterogeneity of vascular endothelial cells. A, B UMAP plots of 11 vascular endothelial cell clusters obtained from further clustering analysis. C, D Bar graphs showing the relative proportions of each endothelial cell subtype in each sample. E Dot plot displaying the expression of vascular marker genes across 11 endothelial cell subtypes. F Comparison of endothelial cell subtype abundance between different groups. G, H Volcano plots show all upregulated and downregulated genes in the 11 endothelial cell subtypes
