Fig. 2

The expression of COX-2 in ESCs treated with IL-1β is shown (n = 4). GAPDH is shown as the internal control. A: Representative blots illustrating the effect of IL-1β (1 nM) treatment on COX-2 and GAPDH for 0 min to 32 h. C: Representative blots illustrating the effect of 0–1- nM IL-1β treatment on COX-2 and GAPDH for 16 h. The blot layout is in the same order as the graph in panels B and D, respectively. *P < 0.05 vs. controls. **P < 0.001 vs. controls
