  • Material for undifferentiated state-maintaining culture
    Patent number: 10316292
    Abstract: A culture method (a preservation method) of somatic stem cells does not use a chemical such as DMSO that affects a differentiation function of somatic stem cells. A material for an undifferentiated state-maintaining culture for a somatic stem cell, having a naturally occurring polysaccharide; a culture liquid in which the material for the undifferentiated state-maintaining culture is dispersed; a somatic stem cell-containing culture liquid in which the somatic stem cell is suspended in the culture liquid; and a culture method for mesenchymal stem cells in which a naturally occurring polysaccharide is used.
