Trans-Cinnamaldehyde Inhibits IL-1β-Stimulated Inflammation in Chondrocytes by Suppressing NF-κB and p38-JNK Pathways and Exerts Chondrocyte Protective Effects in a Rat Model of Osteoarthritis

Figure 2

High concentration of TCA decreases cell viability. We initially examined the cytotoxicity of TCA to primary SW1353 cells and varying concentrations of TCA (2-20 μg/ml) for 24 h. Each value indicates the mean ± SEM from three independent experiments. P<0.05.
