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

Figure 3

H&E-stained sections of nevus tissue in untreated, fresh, and cryopreserved groups. Massive vacuolation was observed (red arrowheads) in the epidermal layer in the fresh and cryopreserved group. Nevus cell nests existed in the dermal layer and melanin pigmentation still remained in all the groups.
