PRODUCTION METHOD FOR T CELLS OR NK CELLS, MEDIUM FOR CULTURING T CELLS OR NK CELLS, METHOD FOR CULTURING T CELLS OR NK CELLS, METHOD FOR MAINTAINING UNDIFFERENTIATED STATE OF UNDIFFERENTIATED T CELLS, AND GROWTH-ACCELERATING AGENT FOR T CELLS OR NK CELLS

摘要

The purpose of the present invention is to provide a production method for T cells or NK cells, medium for culturing T cells or NK cells, a method for culturing T cells or NK cells, a method for maintaining the undifferentiated state of undifferentiated T cells, and growth-accelerating agent for T cells or NK cells, which enable efficient growth of T cells or NK cells, and enable maintaining of a state (e.g., undifferentiation) of the cells. The present invention pertains to a production method that is for T cells or NK cells and that comprises culturing T cells or NK cells in a medium containing a bisbenzylisoquinoline alkaloid represented by formula (X-1) or formula (X-2) or a compound obtained by cleaving one ether bond thereof or a pharmaceutically acceptable salt thereof, and the like.
