The effects of psoralen on TNF-α-induced chondrocytes gene and protein expression. (a and b): chondrocytes were treated with TNF-α or TNF-α plus PSO for 24 and 48 hours. (c and d): immunofluorescent staining of COL2A1 and MMP13 of chondrocytes for 48 hours treatments. (e and f): western blotting for type II collagen (Collagen II), Aggrecan, MMP13 of chondrocytes for 48 hours treatments. (*) p< 0.05 (vs. control) and (#) p< 0.05 (vs. TNF-α) were accepted as statistically significant, n=3.
