Natural Fish “Antifreeze” May Be a Breakthrough for Blood Storage

In an effort to improve cryopreservation of cells, tissue and organs, new research in Nature Communications uses “a synthetic, biomimetic, polymer, which is capable of slowing the growth of ice crystals in a manner similar to antifreeze (glyco)proteins to enhance the cryopreservation of sheep and human red blood cells.” In addition, “We find that only 0.1 wt% of the polymer is required to attain significant cell recovery post freezing, compared with over 20 wt% required for solvent-based strategies (glycerol or dimethyl sulfoxide).” The results suggest a crucial role in improving “the storage and distribution of biological material for transplantation.”
