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

Figure 7

Micrographs of the HE-stained sections of the pressurized nevus specimens after 6 days of culturing. The original epidermis of the nevus specimens remained intact and seeded keratinocytes were not observed in the control group. The original epidermis was removed in the 200, 500, and 1000 MPa groups. The attachment of seeded keratinocytes on the pressurized nevus was only observed in the 200 MPa group. The open arrowheads indicate the original epidermis. The closed arrowheads indicate the seeded keratinocytes. Scale bar = 50 μm.
