CCK-8 result of the MSCs cultured in the dextran/gelatin hydrogel encapsulated with no supplement (control), 1000 μg/mL blank PLGANPs (PLGANPs), 1000 μg/mL TGF-β3-loaded PLGANPs (TGF-β3-PLGANPs), and the hydrogels with no supplements cultured in the medium containing 10 ng/mL TGF-β3 (TGF-β3) for 7, 14, and 28 days. The hydrogels with no seeded cell were chosen as the negative control. The data were expressed as the mean ± SD (n = 4). The samples indicated with (∗) had a significant difference between the two groups (p < 0.05). The samples indicated with (A) had a significant difference compared to the same group on day 7 (p < 0.05) and (B) had a significant difference compared to the same group on day 14 (p < 0.05).
