Proangiogenic effects of N-NAM in the postischemic brain. (a) N-NAM (5 µg) or scN-NAM (5 µg) was administered intranasally three times daily at 4, 5, and 6 days after 60 min of MCAO. (b,c) At 7 days post-MCAO, coronal brain sections were stained using cresyl violet (b) or double-fluorescence-stained with anti-rat endothelial cell antigen-1 (RECA-1) antibody and DAPI (c). Representative images are presented (c), and RECA-1-positive vessel densities are presented as the mean ± SEMs (n = 5) (d). Total vessel lengths were measured using AngioTool software 0.6a (https://angiotool.software.informer.com/0.6/), and the results are presented as the means ± SEMs (n = 5) (e). Scale bars, 100 μm, **p < 0.01 versus the 50 nM N-NAM-treated group.
