Pericytes are activated and leave the capillary wall after experimental stroke. a Confocal images showing GFP⁺ pericyte around blood vessel (CD31, blue) in the quiescent state in the contralateral hemisphere, scale bar 5 µm. b An activated pericyte (green) with prominent soma along the capillary (CD31, blue) expressing NG2 (red) in the infarct area, 1 day after stroke, scale bar 5 μm. c All GFP⁺ pericytes express NG2 (red) in the infarct area at 1 day, scale bar 20 μm. d Projection of a confocal stack showing a GFP⁺ pericyte (arrow) that leaves the blood vessel (CD31, blue) in the infarct core, 7 days after injury, scale bar 10 μm
