Figure 8. Immunohistochemistry of MMP-1, 2, and 9 in transplanted tissues.

Figure 8

During the experiment stages, MMP-1, 2 and 9 had different changes in expression level. MMP-1 was expressed in the glandular epithelium and stroma in 14d, 21d and 28d group, and MMP-1 expression was increased in 31d group. MMP-2 was weakly expressed in transplanted tissues in 14d and 21d group, whereas expression in epithelial and stromal cells was significantly increased in 28d and 31d group. MMP-9 was weakly expressed in glandular epithelium and stromal cells, with no change in 14d, 21d and 28d group in expression level. However, MMP-9 expression was increased significantly in 31d group.
