Figure 5From: Effects of macro- versus nanoporous silicon substrates on human aortic endothelial cell behaviorFluorescence confocal microscopy. Confocal imaging for HAECs cultured on three different substrates at 37°C for 48-h incubation. The actin filaments were stained with actin-stain 670 phalloidin for 30 min (red), and the nucleus was stained with NucGreen Dead 488 for 10 min (green).Back to article page
