3D reconstructions for each condition. Within each data set, individual fibrils, grouped fibrils, and complex fibril interactions such as merging, splitting, and interweaving are present. The considerable differences between networks are primarily due to the varied polymerization conditions, although some there are some contributions from varied sample volumes between data sets and spatial variance of collagen density. Scale bars vary across samples due to differences in sample volume inherent in the FIB-SEM technique.
