Survival of unprotected, mammalian plateau-phase cells following freezing in liquid nitrogen. 1976

J Frim, and J Kruuv, and H E Frey, and G P Raaphorst

Unprotected, mammalian cells in plateau phase are at least a factor of four times more sensitive to freeze-thaw damage than exponential-phase cells. The former suffer about 15-20% more sublethal damage after one freeze-thaw cycle than the latter and repair this damage more slowly. Exposure of plateau-phase cells to freeze-thaw damage lengthens the time required to traverse the cell cycle in the exposed generation. These cells may more closely represent the state in tissues than exponential-phase populations.

UI	MeSH Term	Description	Entries
D009584	Nitrogen	An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.
D002470	Cell Survival	The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability.	Cell Viability,Cell Viabilities,Survival, Cell,Viabilities, Cell,Viability, Cell
D005615	Freezing	Liquids transforming into solids by the removal of heat.	Melting
D006224	Cricetinae	A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.	Cricetus,Hamsters,Hamster
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014021	Tissue Preservation	The process by which a tissue or aggregate of cells is kept alive outside of the organism from which it was derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
