  • ESTABLISHMENT OF INDUCED PLURIPOTENT STEM CELL USING CELL-PERMEABLE REPROGRAMMING TRANSCRIPTION FACTOR FOR CUSTOMIZED STEM CELL THERAPY
    Publication number: 20120095188
    Abstract: The present invention relates to a reprogramming transcription factor recombinant protein in which a macromolecule transduction domain (MTD) is fused to a reprogramming transcription factor to obtain cell permeability. The present invention also relates to a polynucleotide for coding said reprogramming transcription factor recombinant protein and to an expression vector of said cell-permeable reprogramming transcription factor recombinant protein. Treating a somatic cell with the cell-permeable reprogramming transcription factor recombinant protein induces the reprogramming of the stem cell-specific gene of the somatic cell, and thus can be effectively used in the establishment of an induced pluripotent stem cell (iPS cell) having characteristics similar to those of an embryonic stem cell in terms of morphology and genetics.
