Title:
STORAGE LIQUID FOR MAMMALIAN CELLS
Document Type and Number:
WIPO Patent Application WO/2020/189538
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel storage liquid for storing mammalian cells over a long period of time in a non-frozen state. Ascorbic acid and/or niacin are added to an isotonic liquid to give a storage liquid. Then the storage liquid is mixed with platelets and stored under shaking. Thus, deterioration in the functions of the platelets and a decrease in the survival rate thereof can be prevented for at least 10 days. When the aforesaid storage liquid is mixed with mesenchymal stem cells, megakaryocytes or T cells and stored in a non-frozen state, deterioration in the functions of these cells and a decrease in the survival rate thereof can be prevented for at least from several days to several ten days.
