A composition for the cryopreservation of cells according to the present invention at least comprises sericin and one or more components selected from the group consisting of amino acids and saccharides. Further, a method for the cryopreservation of cells according to the present invention comprises the steps of placing target cells in the abovementioned composition for the cryopreservation of cells and cryopreserving them. According to the composition for the cryopreservation of cells of the present invention, cells can be cryopreserved over a long period of time without the use of serum and components derived from serum.

Compositions for cryopreservation of cells

The purpose is to prevent, ameliorate or relieve various conditions induced in the dried oral cavity or to improve the stability of a denture during use. A solution for treating a denture or a denture stabilizer comprising sericin can be used.

Use of sericin for improving the feeling in use of denture
