発明の名称 (英語) USE OF PEPTIDYL-PROLYL ISOMERASE PIN1 FOR CONTROLLING STABLE MAINTENANCE AND RENEWAL OF STEM CELLS
発明の概要(英語) Provided is a technique which enables highly efficient and stable establishment, maintenance and renewal of induced pluripotent stem (iPS) cells. A method for producing induced pluripotent stem cells from somatic cells, which comprises a step for enhancing the expression of peptidyl-prolyl isomerase Pin1 in somatic cells. Induced pluripotent stem cells which are produced by the above-described method. An agent for enhancing somatic cell reprogramming, a medical agent for activating the self-renewal of induced pluripotent stem cells and a medical agent for maintaining the pluripotency of induced pluripotent stem cells, each of which contains a substance that enhances the expression of peptidyl-prolyl isomerase Pin1 in somatic cells and/or peptidyl-prolyl isomerase Pin1. A medical agent for inhibiting the self-renewal of induced pluripotent stem cells, a medical agent for impairing the pluripotency of induced pluripotent stem cells and a medical agent for killing induced pluripotent stem cells and/or cancer stem cells, each of which contains a substance that inhibits peptidyl-prolyl isomerase Pin1. An Oct-4 protein stabilizer and an agent for enhancing the transcriptional activity of Oct-4 protein, each of which contains peptidyl-prolyl isomerase Pin1 and/or a Pin1 gene.
