Fig. 4 — Characterization of GelMA-Exos Hydrogels. (A) Compressive and Stretched testing revealed the mechanical properties of GelMA-Exos hydrogels. (B) Swelling ratios were quantified for GelMA-Exos hydrogels over time. (C) Degradation rates were determined for GelMA-Exos hydrogels at multiple time points post-fabrication. (D) Release kinetics of exosomes were profiled from GelMA-Exos hydrogels over 28 days. (E) H&E staining visualized the degradation process of GelMA-Exos hydrogels across distinct time points.
