Abstract
A process is described in which surface attached living cell cultures are treated, cooled, stored and revived in such a manner as to retain their viability and their adherence to culture surfaces.
Claims21
In a process for cooling, storing and reviving surface attached living cultured cells, the steps of:
- exposing living cultured cells which are attached to a surface of a storage vessel to a storage medium which is relatively non-toxic to such cells and which is compatible therewith during cooling to a temperature below 0.degree. C, storage and subsequent warming processes;
- cooling said vessel and the surface attached living cells therein to a storage temperature below 0.degree. C effective for arresting the metabolism of the cells;
- and
- storing said vessel and said surface attached cells at said storage temperature for an extended period of time.
