Photomicrographs of mouse carotid arteries after arterial dilation and endothelial denudation. (a and b) TEM from Mac-1^+/+ mice. (a) Uninjured artery. (b) Artery 24 hours after injury (original magnification: ×3,000). (c–f) Verhoeff’s elastin stain 28 days after vascular injury. (c) Mac-1^+/+ artery (×38); (d) Mac-1^–/– artery (×38); (e) Mac-1^+/+ artery (×150); (f) Mac-1^–/– artery (×150). Neointima separates the internal elastic lamina (arrows) from the lumen.
