Figure 7. — Characterization of Gelma hydrogel, Gelma/Geltain hydrogel and Gelma/nanoclay hydrogel. (a) Scanning electron micrographs of Gelma, Gelma/Geltain and Gelma/nanoclay hydrogels. Scale bars, 200 μm. (b) Profile of sEVs released from the hydrogels. (c) Rheological properties of the hydrogels. (d) Swelling ratio of the hydrogels in PBS (pH 7.2) at 37°C. (e) Degradation ratio and mechanical properties (f) the hydrogels. For mechanical properties analysis, data were presented as mean ± SD of three number of replicates. t-test was applied to each group in order to compare mean beta values. ***P < 0.001.
