Figure 6. Cell-cell communication in the GSE166676 single-cell dataset. (A, B) Heatmap of cell-cell communication between different cell types in the control group (A) and the AAA group (B) in the GSE166676 single-cell dataset. (C, D) Interaction of costimulatory molecules between different cells in the control group (C) and AAA group (D). The color of the dot represents the communication strength, and the size of the circle represents the significance of the strong p-value. Abbreviations: AAA: abdominal aortic aneurysm; CON: Control.
