Choline Chloride Improves the Desiccation Tolerance of Chinese Hamster Ovary Cells
Keyword(s):
Recently there has been much interest in using sugars such as trehalose to preserve mammalian cells in a dry state as an alternative to cryopreservation (1–5). However, some studies indicate that sugars alone may not be sufficient to prevent cell injury during drying. Other factors like sodium toxicity, ionic imbalance and pH excursions during dehydration are a few of the mechanisms that have been hypothesized to decrease the viability of mammalian cells. In the present study, we investigated whether or not substituting sodium chloride with choline chloride (2-hydroxy-N, N,N-trimethylethanaminium chloride) in the preservation medium improves desiccation tolerance of Chinese Hamster Ovary (CHO) cells.
