Figure 14From: 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 Culturing HUVECs on POSS-PCU-CD34. Growth and proliferation of HUVECs were observed on POSS-PCU-CD34 even after being exposed to physiological flow conditions. Scale bar represents 40 μm.Back to article page
