Quantification of Spatial Parameters in 3D Cellular Constructs Using Graph Theory

Figure 5

Collagen I hydrogels compact as a function of cellular density. The diameter of the collagen I gels at each time point was measured using Image J and plotted as a percentage of the original volume. Changes in cellular density resulted in significant changes in compaction over the observed 24 hours time course, where an increase in cell density correlated with an increase in gel compaction.
