Profiling of different aortic segments using scRNA-seq. a Experimental procedure for five consecutive aortic segments. Full-length aortas were separated from five C57BL/6 male mice at 12 weeks and dissected into five segments based on the anatomical landmarks. Different aortic segments were digested with the same dissociation program to obtain single-cell suspensions for sequencing with 10X Genomics. b Elastin staining of five segments showed the complete structure of the aorta with decreased diameter. c The heatmap showed top marker genes to identify all aortic cells into eight types. The order of marker genes was in accordance with the order of cell types. d A dot plot indicated the relative expression of marker genes in the distinct cell population. The dot size reflects the percentage of cells expressing the selected gene in each population. e The distribution of all subtypes in different segments was manifested by the t-SNE plot. f The proportion of special subclusters showed significant variation among five aortic sections, especially VSMC 2, 3, and 4.
