SEM visualization of thrombotic material in the mouse carotid artery induced by FeCl₃ application. The figure shows (A) elongated RBCs (asterisks); (B) an RBC cluster; (C) spherical structures (asterisks; not all are labeled); (D) a spherical structure covered with smaller, rough-appearing bodies; and (E) complexes composed of rough and amorphous-appearing material. The time course was 1 minute after FeCl₃ application for all samples.
