CULTURE METHOD FOR STABLE UNDIFFERENTIATED PROLIFERATION OF PLURIPOTENT STEM CELLS

摘要

The present invention provides a culture method for the proliferation of a pluripotent stem cell while maintaining an undifferentiated state, comprising a step of cultivating a pluripotent stem cell in a medium added with at least one selected from the group consisting of ethanolamine, ethanolamine analogs and pharmaceutically acceptable salts thereof, and substantially free of ²-mercaptoethanol or containing ²-mercaptoethanol at a concentration of not more than 9 µM, and the like.
