Testing various combinations of cryoprotective agents for human skin cryopreservation by vitrification method

Abstract

Modern translational medicine, pharmacology and other fields require effective skin cryopreservation technology. Vitrification is promising technology for this aim. This rapid freezing technique minimizes hexagonal ice crystals formation, time of stress condition for cells in samples and dehydration both in the cytoplasm of cells and in the extracellular space. This study is aimed at finding the optimal combination of extracellular (sucrose, mannitol, polyethylene glycol and FBS) and intracellular (DMSO, glycerol, ethylene glycol) cryoprotective agents to achieve the highest viability and tissue structure preservation of skin samples after vitrification.
