GelMA-Exos significantly alleviates the damage in IL-1β-treated chondrocytes. (a) chondrocytes were detected by qPCR after 7 days of culture in each group (n = 3); (b) Immunofluorescence detection of chondrocytes after 7 days of culture in each group; (c) quantitative analysis of fluorescence intensity of COL-2 and MMP-13 (n = 3). (d) Chondrocytes were detected by western blot analysis after 7 days of culture in each group (n = 3); (e) quantitative analysis of Western blot (n = 3). ANOVA followed by Tukey’s test was used for statistical analysis (, , and ).
