(a) Electron micrograph of titania nanoleafy textured stent surface (magnification ×40 000). Fluorescence imaging of (b) endothelial cells stained for F-actin (red) and PECAM1 (green) and (c) smooth muscle cells stained for F-actin (red) and nucleus (blue) on nanotextured SS surfaces, showing preferential adsorption and proliferation of ECs over SMCs on nanoleafy SS surface.

H&E images of rabbit iliac artery after 2 months implantation of (d) SS bare-metal stent and (e) nanotextured SS stent, showing nearly 50% decrease in neointimal stenosis for the nanotextured stent. (f) Immunofluorescent en-face stained images of wheat germ agglutinin on ECs in nanotextured stent implanted artery, showing complete endothelialization (scale bar: 10 μm).
