Figure 6 Histomorphometric analysis. (A) Representative photomicrographs of coronary tissue sections that were used to determine stenosis rates after implantation of unloaded polymer, integrin-binding cyclic Arg-Gly-Asp peptide (cRGD)-loaded, or bare-metal stents after 4 and 12 weeks (magnification 40x). L = lumen; NI = neointima; arrows indicate neointimal area. (B) Quantification of infiltration with chronic inflammatory cells (CIC) around the stent struts.
