Light micrographs of serial sections of an injured carotid artery from a rabbit injected with human-derived NPs. The artery was collected at 35 days postoperatively. The uninjured artery from this rabbit is that shown in Fig. 2. Consecutive sections were stained with an elastin van Giesen stain (left), von Kossa stain (middle), and a macrophage-specific antibody (right). Magnification is ×5. Arrows indicate an area that shows positive staining for both calcification and macrophages.
