The rabbit thoracic aorta was studied by EM and vital staining with Evans blue at varied points of time after a single lesion produced by an embolectomy catheter. EM of white areas: the surface cells of the myo‐intimal thickening resembled endothelial cells with a discrete occurrence of microfilaments inside the plasma‐membranes and rather differentiated flap‐like junctions. EM of blue areas: the surface cells resembled modified smooth muscle cells with a heavily contrasted zone just inside the luminal plasma membrane containing closely packed microfilaments. The cell contacts either were missing, or they presented undifferentiated side‐to‐side contacts.
