IL-1 effects on aggregate modulus. (a) Aggregate modulus of the cartilage explants treated with various concentrations of IL-1α (black bars) or IL-1β (gray bars). The data is expressed as MPa + standard error. There are significant effects of isoform with α < β and concentration (conc) with 0 = 0.1 > 0.01 = 1 = 10. (b) Aggregate modulus of the meniscal explants treated with various concentrations of IL-1α (black bars) or IL-1β (gray bars). There is a significant effect of concentration (conc) with 0 > 0.01 > 0.1 > 1 = 10.
