Figure 1. DDR1 inhibitor attenuates both constitutive and periostin-induced MMP-13 expression in human OA cartilage. MMP-13 levels in human cartilage explants treated as described in Methods. Means±SD of triplicate samples are shown. Statistical significance was determined by 1-way ANOVA with post-Bonferroni multiple comparison test. p<0.05, control vs. DDR1 inhibitor-treated; p<0.01, control vs. periostin + DDR1- inhibitor.
