Correlation between Tissue Characterization and Dynamic Expression of Matrix Metalloproteinase-2 and Its Tissue Inhibitor in Conjunctival Filtering Bleb of Rats

Figure 2

The expression of MMP-2 in conjunctival and subconjunctival tissue of filtration area. The values represent the mean ± SE of densitometry scans resulting from a western blot procedure. Numbers above bars represent levels of statistical significance among the groups. NS: not significant (N: control group; 1 d: at day 1; 3 d: at day 3; 5 d: at day 5; 7 d: at day 7; 14 d: at day 14; 28 d: at day 28; P: positive control).
