PROCESS FOR PRODUCTION OF HEMATOPOIETIC STEM CELL

摘要

Disclosed is an agent for amplifying a hematopoietic stem cell and/or a hematopoietic progenitor cell, which is useful as a therapeutic method for various hematopoietic diseases and is also useful for the improvement in the efficiency of gene transfer into a hematopoietic stem cell in a gene therapy. Also disclosed is a process for producing a hematopoietic stem cell and/or a hematopoietic progenitor cell, which is characterized by culturing a hematopoietic stem cell in the presence of a compound represented by formula (I) (wherein R1 to R6 are as defined in the description), a tautomer or pharmaceutically acceptable salt thereof, or a solvate of the compound, the tautomer or the pharmaceutically acceptable salt to amplify the cell.
