Inactivated Nevus Tissue with High Hydrostatic Pressure Treatment Used as a Dermal Substitute after a 28-Day Cryopreservation Period

Figure 2

Nevus tissues resected from a patient with giant congenital melanocytic nevi. Untreated, nevus tissue without HHP treatment. Fresh, nevus tissue treated with HPP at 200 MPa. Cryopreserved, nevus tissue cryopreserved at -30°C for 28 days after HHP treatment at 200 MPa. No morphological differences such as shape, color, or size are observed. HHP: high hydrostatic pressurization.
