Representative image of aortic ring network analysis. Endothelial networks are divided into three concentric regions based on structure: unstructured area in close proximity to aortic ring tissue (a), developed/structured endothelial networks (b) and developing networks located in the periphery of the ex vivo tissue culture (c). Radial network growth and uniform quadrant for loop count are defined within the developed endothelial network (b). X closed endothelial loop counted in uniform quadrant. Scale bar = 250 μm
