MMPs drive osteoclast-mediated cartilage degradation. (a,b) Effect of bafilomycin, E64 and GM6001 on osteoclast-mediated release of GAG from (a) acellular or (b) cellular cartilage after 13 days of differentiation. N varies for each graph, as represented by the number of data points. Statistics: (a): bafilomyin, Kruskal–Wallis ANOVA; E64 and GM6001, one-way ANOVA. (b) bafilomycin and E64, one-way ANOVA; GM6001, Kruskal–Wallis ANOVA. (c) Effect of recombinant human TIMP1 (100 nM) on GAG release from osteoclasts cultured on acellular cartilage (n = 18; T test).
