HA gel characterization. (A) Equilibrium swelling ratio (ESR) at 3 h and 24 h for each gel formulation. (B) EVs released per mL of HA-EVs gel at 3 h and 24 h. Values represent the mean ± SEM. Three independent samples (n = 3) were evaluated. ESR results were statistically compared by ANOVA using DMS as a post hoc, while EVs released were compared by independent samples t-test. Statistically significant differences were considered for p < 0.05 and represented with “a” compared to HA and * compared to 3 h.
