摘要
Methods and compositions for cryopreserving somatic cells are provided. In one embodiment, a cell cryopreservation medium is provided which includes an effective amount of arabinogalactan to maintain the viability of cells upon freezing, storage and thawing. The cells may be cooled or frozen during storage to a temperature about or below 4° C., for example, to about −196° C. In one preferred embodimnent, ultrarefined arabinogalactan is provided in the cryopreservation medium, optionally in combination with a second cryopreservation agent, such as dimethyl sulfoxide. The medium can be used for the cryopreservation of a wide variety of different cell types from different sources. For example, mammalian cells, including porcine, canine, human, equine, rodent and bovine cells can be cryopreserved in the medium. The presence of arabinogalactan in the medium protects the viability of cells in the medium during the process of freezing, storage and thawing.
