Fig 7. Quantification of MMP-13 expression.
The COAG exhibited a significant difference in MMP-13 expression on the surface layer compared with that in the OAG (p = 0.0011). The CG showed a significant difference in MMP-13 expression in the middle and deep layers compared with that in the OAG (p = 0.0043 and p = 0.0007, respectively); p<0.05.
