The effect of extracellular matrix geometry on capillary-like structure formation using PDMS fences. (A) Bright field images of capillary-like structures on matrigel with various geometries. Scale bar, 300 μm. (B) Statistical analysis of the mean cord length of capillary-like structures at the center region and boundary region of matrigel (ns, not significant; *, P<0.05; **, P<0.01; ***, P<0.001). Results represent mean±SE from three independent experiments.
