Cryopreservation prolongs the storage time of cells and plays an important role in modern biology, agriculture, plant science and medicine. During cryopreservation, cells may suffer many damages, such as osmotic dehydration, large ice puncture and oxidative damages from reactive oxygen species (ROS). Classic cryoprotectants (CPAs) are failing to dispose of ROS, while antioxidants can turn ROS into harmless materials and regulate oxidative stress. The combination of antioxidants and CPAs can improve the efficiency of cryopreservation while negative results may occur by misuse of antioxidants. This paper discussed the feasibility of antioxidants in cryopreservation.
冷冻保存延长了细胞的储存时间,在现代生物学、农业、植物科学和医学中发挥着重要作用。在冷冻保存过程中,细胞可能会遭受多种损伤,如渗透脱水、大冰晶穿刺以及活性氧(ROS)引起的氧化损伤。传统的冷冻保护剂(CPA)无法清除ROS,而抗氧化剂可以将ROS转化为无害物质并调节氧化应激。抗氧化剂与CPA联合使用可以提高冷冻保存效率,但抗氧化剂使用不当可能会产生负面结果。本文探讨了抗氧化剂在冷冻保存中的可行性。
