The number of arterioles in brain infarction area. Small vessels (diameters ≤ 15 mm) (red arrows) quantification for each group (n = 10) on 21 day following acute IS (D). Identification of blood vessel distribution in BIA using α-SMA immunohistochemical staining, showing notably higher small vessel number in groups 1 (A) and 3 (C) than in group 2 (B) (200×), and similar between groups 3 and 1. Scale bars in right lower corner represent 50 μm. † vs. *, p < 0.0001.
