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

Figure 6

Western blot assay of COL2A1, SOX9, and p-Smad2/3 in IL-1β-activated SW1353 cells pretreated with 15% FYD-CS and/or 10 μM SB431542. Representative bands are shown. The band intensities were compared to that of the corresponding GAPDH band with the same treatment. 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.
