Figure 13From: 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 CD31 and vWF. Compared to POSS-PCU and POSS-PCU-IgG, POSS-PCU-CD34 displayed a higher degree of adherent cells that were positive for CD31 and VWF. Scale bar represents 40 μm.Back to article page
