Fig. 6. Immunofluorescence analysis of the stents. Stent sections after coronary implantation were paraffin-embedded and stained for CD68. Red staining by secondary antibodies was Alexa fluor 568. DAPI staining was performed to visualize the cell nuclei (40×). BMS: bare-metal stent, HA: hyaluronic acid, H-PTX: hyaluronic-acid-coated paclitaxel-eluting stent, P-PTX: poly(L-lactide)-coated paclitaxel-eluting stent, DAPI: 4',6-diamidino-2-phenylindole.
