LPS induces expression of MMP3 and MMP13 (a), and proinflammatory cytokines (b) in ELACs culture. The chondrocytes were treated with LPS at various concentrations (0.125–1 μg/mL) for 24 h, then mRNA levels were assessed by real-time RT-PCR. Results are presented as mean ± SEM. * signifies statistical significance compared with control (*p < 0.05)
