Figure 12From: Surface modification of a polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU) nanocomposite polymer as a stent coating for enhanced capture of endothelial progenitor cells EPC staining with anti-CD34 and VEGFR 2 . Scale bar represents 40 μm. Compared to POSS-PCU and POSS-PCU-IgG, POSS-PCU-CD34 displayed a higher density of cell adherence which were positive for CD34 and VEGFR2.Back to article page
