<p>Chemotaxis assay on conditioned medium prepared from the media (M) and adventitia (A) of AAAs (n = 15) and control aortas (n = 15). Plotted is the number of total leukocytes, monocytes, CD19⁺ B cells, CD44⁺CD62L⁻ memory CD4⁺ or CD8⁺ T cells, CD44⁻CD62L⁺ naïve CD4⁺ or CD8⁺ T cells that have migrated toward the well containing the conditioned medium. *, p<0.05; **, p<0.01; ***, p<0.001.
