Laterally patterned protein adsorption (fluorescently labelled fibronectin) and endothelial cell growth (green: actin cytoskeleton; magenta or blue: nucleus) on micropatterned PEGDMA on PEMA surfaces: (a) Cross and (b–d) linear micropatterns with spatial periods of 50 and 30 μm, respectively. The images were taken after (a–b) 3 h and (c–d) 5 days of cell culture. Insets in (a) and (b) show single cell close up. Scale bars 100 μm
