Arterial wall mechanical characteristics after treatment in collagenase: an in vitro aneurysm model
Fig. 3: Light photomicrograph of the arterial wall after a 2-hour incubation in buffered collagenase. The endothelial lining and the intimal layer of the descending thoracic aorta segment were entirely digested and the media was partially affected (A). Similarly, the suprarenal segment's endothelial and intimal layers were digested (B). The elastic lamina was also disrupted (arrow), and the thickness of the adventitia was substantially reduced. Original magnification: 300 ×.
