Pore diameter of hydrogels decreases as HA percentage increases. (A) Representative cryo-SEM images for 1 – 3% HA hydrogels. Bar = 10 μm (B) One-way ANOVA indicated that pore diameter was significantly affected by HA% (p < 0.001). Tukey’s post-hoc test revealed a significant decrease in pore diameter in the 3% HA hydrogel compared to the other hydrogels. (**p < 0.01, ***p < 0.001). HA functionalized with 294 μM RGD was also tested, indicating that functionalization did not significantly affect pore diameter. Error bars = SD, n=4 for each treatment.
