摘要： According to the present invention, when the novel low-molecular-weight compound RSC-133 is added in a culture process for producing reprogrammed pluripotent stem cells from human differentiated cells, it can increase the efficiency of reprogramming and can significantly reduce the time required for the induction of reprogramming. Particularly, the novel compound RSC-133 can substitute for c-Myc acting as both a reprogramming factor and an oncogenic factor, and it can effectively increase the efficiency of reprogramming in both normal oxygen culture conditions and hypoxic culture conditions. In addition, RSC-133 can inhibit the induction of aging occurring in the reprogramming process, exhibits the effect of promoting cell proliferation, and induces epigenetic activation to improve culture conditions for induction of reprogramming. The present invention will contribute to optimizing a process of producing induced pluripotent stem cells from a small amount of patient-specific somatic cells obtained from various sources, and thus it will significantly improve a process of developing clinically applicable personalized stem cell therapy agents and new drugs and will facilitate the practical use of these agents and drugs. In addition, the novel low-molecular-weight compound RSC-133 can provide a cell culture medium effective for maintaining the undifferentiated state of human embryonic stem cells that are typical pluripotent stem cells. The medium composition containing RSC-133 can effectively induce the proliferation of human embryonic stem cells in an undifferentiated state and can be effectively used for the development of a system for culturing large amounts of embryonic stem cells.
