Extravascular cell swarm. Extravascular cell swarm around a FUS+MB affected arteriole was observed in one animal. (A) A mass of cells began to accumulate adjacent to an affected arteriole at T = 1 h after the onset of sonication, and increased in volume until the end of imaging. (B) The normalized volume, (C) displacement, and (D) speed of cells participating in the swarm, are shown. Blood vessel are shown in red (Texas Red dextran), and EGFP+ fluorescence cells are shown in green. Scale bar: 20 µm. h = hour(s).
