[Retracted] ECM-Mimicking Hydrogels Loaded with Bone Mesenchymal Stem Cell-Derived Exosomes for the Treatment of Cartilage Defects

<div>Biocompatibility evaluation of each group. (a) Live/Dead analysis for each group after 1 day of cell culture; (b) quantitative analysis of live/dead assay (<i>n</i> = 3); (c) CCK8 assay of chondrocytes in each group (<i>n</i> = 5); (d) the cytoskeleton images showed the adhesion of chondrocytes after 3 days of culture in each group; (e) quantitative analysis of cell spread area (<i>n</i> = 3). ANOVA followed by Tukey’s test was used for statistical analysis (<span class="nowrap"><svg height="10.7395pt" id="M2" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162 -10.1025
