Figure 2. The effect of 5-Aza-dC on the extracellular matrix. Primary human conjunctival fibroblasts were pretreated with 5-Aza-dC once daily for 2 days. After passage, the cells were treated with transforming growth factor (TGF)-β2 for 2 days, and then subjected to western blotting. The protein bands were quantified, and the ratios of fibronectin (A) and type I collagen (B) to β-actin were calculated (n=5); *p<0.05. Bars indicate the standard error.
