Cryopreservation of Human Hepatocyte by Sugar-alcohol based CPAs

Different types of sugar alcohol is usually used as cryoprotective agents (CPAs) to preserve human hepatocytes. In this study, a new types of sugar alcohol based CPAs with low toxicity was explored by replacing Me2SO with D-sorbic alcohol, xylosic alcohol and maltol. The Me2SO concentration in CPAs...

Description
Summary:Different types of sugar alcohol is usually used as cryoprotective agents (CPAs) to preserve human hepatocytes. In this study, a new types of sugar alcohol based CPAs with low toxicity was explored by replacing Me2SO with D-sorbic alcohol, xylosic alcohol and maltol. The Me2SO concentration in CPAs was reduced to 5%. Human hepatocytes attached to plastic cover slips were treated with the above CPAs and then placed in the fridge at -80℃ for two weeks. The survival rate, 24h cell detachment and cell morphology were tested and compared with the results using 10% Me2SO as CPAs. The results show that 5% Me2SO with D-sorbic alcohol gives the best results. It is concluded that the new CPAs are effective to human hepatocytes cryopreservation.
