The Alteration of the Epidermal Basement Membrane Complex of Human Nevus Tissue and Keratinocyte Attachment after High Hydrostatic Pressurization

Figure 1

Micrographs of the immunohistochemical staining of type VII collagen. The open arrowheads indicate the remaining original epidermis of the nevus specimens in the control and 100 MPa groups. The closed arrowheads indicate the stained type VII collagen. The type VII collagen was clearly stained in the control, 100 MPa, and 200 MPa groups and weakly stained in the 500 MPa group but was not stained in 1000 MPa group. Scale bar = 100 μm.
