Effect of substrate stiffness. (A) A bright field optical image of human dermal fibroblasts after 6 days on 10:1 PDMS forming an interconnected network around 150 μm squares of PEG-DA. Phalloidin and DAPI stained cells on (B) 10:1 PDMS (C) 20:1 PDMS and (D) 5:1 PDMS shown with the nuclei and cytoskeleton overlaid. (Scale bar on all images = 200 μm).
