42 J. Chamberlain et al. Figure 4 Sham stented animals do not develop a neointima at 28 days (A). Polymorphonuclear cells are seen around the stent strut at 1 day post-stenting (B). A small neointima begins to form at 3 days (C ). Endothelialization of the neointima is seen at 7 days (D). A mature neointima is seen at 28 days (E and F ). Image G is a high power of the boxed area in F, stained with elastic van Gieson. Purple luminal stain is an artefact caused by the T8100 resin. Open triangles depict the IEL; ﬁlled triangles the external elastic lamina, S marks the stent. Scale bar represents 50 mm.
