Figure 4 MMP-9 immunostaining for skin biopsy form one of control group. (A) H&E staining; Melanocytes identified (Black arrows), no epidermal vacuolization or dermal inflammation. (B) MMP-9 immunostaining; Expression in epidermal cells (Black arrows) and few stromal dermal cells (Red arrows) (+1). H&E, hematoxylin and eosin; MMP-9, matrix metalloproteinase-9.
