MMP-13 and BMP-2 productions by human chondrocytes in ctrl, COT, IL-1β and COT IL-1β conditions.

<p>Results were expressed as mean ± 95% confidence intervals of 12 independent experiments performed with chondrocytes isolated from 12 different patients. **p-value<0.01, ***p-value<0.001. (a) MMP-13 = matrix metalloproteinase-13, (b) BMP-2 = bone morphogenetic protein-2, ND = non detectable.
