Semaphorin 3A Inhibits Inflammation in Chondrocytes under Excessive Mechanical Stress

Figure 5

Effect of Sema3A on protein expression of IL-1β and MMP-13 under excessive mechanical stress. ATDC5 cells treated with various concentrations of Sema3A were subjected to excessive CTS for 24 h. Protein expression of IL-1β and MMP-13 was determined by Western blot analysis. β-actin was used as a loading control.
