Figure 1
Photomicrographs showing the immunohistochemical expression of MMP-2 and TIMP-2 in tissue sections. (a) Normal buccal mucosa showing negative expression for MMP-2, ×20. (b) Normal buccal mucosa showing negative expression for TIMP-2, ×20. (c) Inflammatory bowel used as positive control for MMP-2, ×20. (d) Placenta used as positive control for TIMP-2, ×20. (e) Mild dysplasia showing weak positive expression for MMP-2, ×20. (f) Mild dysplasia showing weak positive expression for TIMP-2, ×20. (g) Moderate dysplasia showing moderate positive expression of MMP-2, ×20. (h) Moderate dysplasia showing moderate positive expression of TIMP-2, ×20. (i) Severe dysplasia showing strong positive expression of MMP-2, ×20. (j) Severe dysplasia showing strong positive expression of TIMP-2, ×20.
