The present invention provides a method for improving the efficiency of inducing a pluripotent stem cell, and a vector and composition used for the method. The inventors succeeded in significantly increasing the efficiency of inducing a pluripotent stem cell by further introducing a vector including a KLF gene and not including an OCT gene and a SOX gene in pluripotent stem cell induction including a step for introducing a vector including a KLF gene, an OCT gene, and a SOX gene in this order. This method is capable of efficiently inducing a pluripotent stem cell under temperature conditions closer to a physiological environment, and has excellent characteristics in that the vector is rapidly eliminated after pluripotent stem cell induction. The present invention makes it possible to induce a pluripotent stem cell with greater efficiency. |
