Composition analysis of regenerated cartilage. A) Immunohistochemical analysis and protein distribution heatmap of various proteins expression levels in the regenerated cartilage of the blank control (BC) group, PEGDA + dECM (PE) group and PEGDA + dECM + EVs (PEE) group after 24 w. B) Analysis of protein distribution. C-E) Composition and mechanical analysis of regenerated cartilage. C) Total collagen content, D) collagen II content, and E) compression modulus of regenerated cartilage in various groups, as indicated, after 3 and 24 w. Data represent the mean ± standard deviation (*P < 0.05 compared with other groups). Data represent the mean ± standard deviation (Scale Bar: 50 μm) (NS > 0.05, *P < 0.05 compared with other groups).
