Testing of various protocols for human skin cryopreservation by vitrification method

Optimization of skin cryopreservation technology is an important task for translational medicine, pharmacology, and a list of other fields. One of the promising approaches is vitrification. This rapid freezing technique allows one to ensure minimal damage to the sample by equating the formation of ice crystals and dehydration both in the cytoplasm of cells and in the extracellular space. This study is aimed at finding the optimal combination of cryoprotective agents (DMSO, glycerol, sucrose and polyethylene glycol) to achieve the highest viability of skin samples after vitrification. Keywords: skin, vitrification, MTT, DMSO, glycerol, sucrose, polyethylene glycol. ### Competing Interest Statement The authors have declared no competing interest.
