Monocyte chemotactic protein-1 eluting coils implanted in murine saccular aneurysm model exhibit increased tissue ingrowth compared with PLGA control, as shown in our previous study (9) and characteristics of aneurysms per group do not differ significantly (Figures S1A,B in Supplementary Material) despite differences in luminal ingrowth (Figure S1C in Supplementary Material). This evidence concerns the gene CCL2 and aneurysm.
