Fuyuan Decoction Enhances SOX9 and COL2A1 Expression and Smad2/3 Phosphorylation in IL-1β-Activated Chondrocytes

Figure 5

Quantitative RT-PCR assay of COL2A1 and SOX9 in IL-1β-activated SW1353 cells pretreated with 15% FYD-CS and/or 10 μM SB431542. The data are expressed as the mean ± SD (). versus the control. versus the group treated with IL-1β and FYD-CS; versus the group treated with IL-1β; versus the group treated with IL-1β, FYD-CS, and SB431542.
