Figure 3: — Microstructural analysis of collagen-based hydrogels. HA and DS increase both matrix pore size and fiber radius, while CS leads to decrease in fiber pore size. A) Representative images of collagen fibers. B-C) Addition of DS and HA leads to increases in pore size and radius. D) HA decreased the solid fraction following processing of confocal images. E) DS and HA decreased the number of collagen fibers, while CS led to increased amounts of fibers when compared to collagen only. Scale bar = 50 μm. Error lines represent the SEM. Statistical significance denoted as NS is non-significance, * <0.05, **<0.01, *** <0.001, **** < 0.0001.
