Additive For Culturing Stem Cells, Culturing Medium, And Culturing Method
Abstract: The present invention is characterized in that it provides: an additive for culturing stem cells, comprising a polysaccharide other than dextran sulfate having a molecular weight of 4,000 kDa-40,000 kDa; and a medium for culturing stem cells, comprising a polysaccharide other than dextran sulfate having a molecular weight of 4,000 kDa-40,000 kDa. The present invention is also characterized by carrying out suspension culture of stem cells using a medium for culturing stem cells, comprising a polysaccharide other than dextran sulfate having a molecular weight of 4,000 kDa-40,000 kDa. The present invention makes it possible to improve the rate of cell mass formation of stem cells, to control the morphology thereof, and also to improve the rate at which stem cells multiply and the rate that stem cells remain undifferentiated, during suspension culture of stem cells.
