Figure 2. Notch-1-cKO in macrophages inhibited the elastic lamina degradation and macrophages infiltration in AAA. (A) representative image for Masson’s staining, α-SMA staining, CD68 immunostaining, and Verhoeff-van Gieson staining; (B) statistical data for AAA areas, macrophages, smooth muscle cells as well as ratio of aortic dissection. N = 9, *P < 0.05, **P < 0.01, apoE-KO/Notch-1MAC-KO group vs. apoE-KO/Notch-1WT group.
