Fig. 3 A , Nonaneurysmal aortic wall stained with Movat's stain, which stains elastin black , smooth muscle red , and collagen and ground substance green to yellow . Aortic media is characterized by distinct elastin lamellar units composed of elastin layers separated by smooth muscle, collagen, and ground substance. (Small white bar = 200 μm). B, Aneurysmal aortic wall stained with Movat's stain. In aneurysmal aortic wall, structure of media is destroyed and there is deficiency of elastin and loss of smooth muscle.
