Figure 4 Stent design, mechanical properties, and in vitro integrin-binding cyclic Arg-Gly-Asp peptide (cRGD) release from the stent. (A) Scanning electron microscopy photographs showing smooth surfaces of the polymer stent coating after complete expansion of the stent and after simulated use (magnification in the left panel 10x, in the right panel 100x). (B) The cRGD-coated stent release kinetic profile over 72 h.
