Effects of miR-24 on neointimal formation at two weeks after vascular injury and gene delivery: (A) Representative cross-sections of hematoxylin-eosin (HE) in different groups. Left (100× magnification, scale bar represents 100 μm), right (400× magnification, scale bar represents 20 μm); (B,C) Quantitative analysis of the neointimal formation (compared to Sham group, * p < 0.05; compared to PBS group or Ad-Scramble group, #
p < 0.05, n = 6); (D) Ratio of intima to media (compared to Sham group, * p < 0.05; Compared to PBS group or Ad-Scramble group, #
p < 0.05, n = 6). A: Adventitia; M: Media; Ni: Neointima.
