CD13⁺ cells increase in mouse and human brains at a delayed time point after ischemic stroke. A A decrease in brain CD13⁺ cell numbers acutely after MCAO and MFI of CD13 after stroke (n = 3–5/gp). B Increase in the brain CD13⁺lectin⁺cells at day 15 post-MCAO (n = 4/gp). C An increase in CD13⁺ percentage area at a subacute time point after stroke in human AIS patients. Magnification 20X, scale bar 50 µm, (n = 8–9). Data presented as mean ± SEM. Two-group comparisons were analyzed by unpaired t-test with Welch’s correction. Three-group data were analyzed by ordinary one-way ANOVA with Tukey’s multiple comparisons test (**p < 0.01, ***p < 0.001, ****p < 0.0001)
