Correlation between Tissue Characterization and Dynamic Expression of Matrix Metalloproteinase-2 and Its Tissue Inhibitor in Conjunctival Filtering Bleb of Rats
The expression of TIMP-2 in the epithelial layers of the normal conjunctiva and in the conjunctival filtration area (immunofluorescence staining, 100x amplification). (a) Control group: staining of TIMP-2 only in the epithelial layers of the normal conjunctiva was weak. (b, c) At day 7 and at day 28: abundant staining for MMP-2 was detected in both the epithelial and stromal layers of cystic filtering blebs. (d) Negative controls (at day 7: absence of primary antibody) showed negative staining ( indicates staining).
