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

Figure 4

Micrographs of the immunohistochemical staining of type VII collagen in the nevus specimens with CE after implantation. The open arrowheads indicate the implanted CE in the 200 MPa and 500 MPa groups. The closed arrowheads indicate the stained type VII collagen. The type VII collagen was clearly stained in the 200 MPa group but not in the 500 MPa or 1000 MPa groups. Scale bar = 100 μm.
