The present disclosure provides a culture substrate for culturing stem cells, the culture substrate including a surface portion having: soft regions that extend side by side along a plurality of directions intersecting each other; and a plurality of stiff regions compartmented by the soft regions, wherein in the surface portion, the stiff regions have acute angle parts protruding toward the soft regions, and the cells can be deformed into a shape that is accommodated within the region of the stiff regions.

Culture substrate, method for manufacturing culture substrate, and culturing method and culturing device for stem cell

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.
