Terminally differentiated somatic cells can be reprogrammed to generate induced pluripotent stem (iPS) cells by overexpression of a defined set of transcription factors. Typically OCT4, SOX2, c-Myc and KLF4 (OKSM) are the 4 reprogramming factors that together are sufficient to reprogram differentiated cells to an embryonic-like state termed iPS (induced pluripotent stem) cells. The OKSM combination was identified initially by screening 24 pre-selected factors in mouse embryonic fibroblasts (MEFs). The iPS cells are morphologically and phenotypically similar to embryonic stem (ES) cells and offer exciting possibilities in stem cell research and regenerative medicine. This lentivector gene clone contains all these 4 human reprogramming transcription factors that are expressed from a single transcript using 2A peptide-mediated self-cleaving elements: Oct4-2A-Sox2-2A-Klf4-2A-c-Myc.
