摘要:
The present invention aims to provide a culturing method and a method for producing a cell population containing a neural crest cell, the methods being able to stably mass produce the neural crest cell from a pluripotent stem cell with quality that allows the cell to be used in a therapy with a cell, and a method for producing a mesenchymal stem cell and the like using the neural crest cell. The method for selectively culturing a neural crest cell in a cell population containing a neural crest cell and/or a neural crest progenitor cell of the present invention comprises a culturing step of adherent culturing the cell population containing the neural crest cell and/or the neural crest progenitor cell, in the presence of one or more extracellular matrices selected from the group consisting of laminin with its α chain being an α1 chain and its β chain being a β1 chain, laminin with its α chain being an α2 chain and its β chain being a β1 chain, laminin with its α chain being an α2 chain and its β chain being a β2 chain, and laminin with its α chain being an α5 chain and its β chain being a β1 chain, and extracellular matrices containing integrin-binding sites of these laminins.
