Supplementary Figure 4: Microvascular pathology during cerebral ischemia

(a) Schematic showing timeline and approach for in vivo imaging during transient cerebral ischemia.
(b-d) In vivo time-lapse sequences captured from the cerebral cortex showing collapse and reperfusion of SMC-covered (arrows) (SMA-mCherry+) but no change in diameter in pericyte-covered (NeuroTrace+) vessels.
(e) Percent changes in diameter from baseline in SMC and pericyte covered vessels showing significant vessel collapse/constriction during ischemia only on SMC-covered vessels (pericyte covered: 28 vessel locations, SMC covered: 23 vessel locations from n=3 mice, unpaired two-tailed student’s t-test p values as indicated during: t=6.244279 df=4, after: t=1.104133 df=4).
