Abstract
Induced pluripotent stem (iPS) cells can be generated using retroviral
vectors expressing Oct4, Klf4, Sox2, and cMyc. Most prior studies have
required multiple retroviral vectors for reprogramming, resulting in high
numbers of genomic integrations in iPS cells and limiting their use for
therapeutic applications. Here we describe the use of a single lentiviral
vector expressing a "stem cell cassette" composed of the four transcription
factors and a combination of 2A peptide and internal ribosome entry site
technology, generating iPS cells from postnatal fibroblasts. iPS cells
generated in this manner display embryonic stem cell-like morphology,
express stem cell markers, and exhibit in vivo pluripotency, as evidenced by
their ability to differentiate in teratoma assays and their robust
contribution to mouse chimeras. Combining all factors into a single
transcript achieves the most efficient reprogramming system to date and
allows derivation of iPS cells with a single viral integration. The use of a
single lentiviral vector for reprogramming represents a powerful laboratory
tool and a significant step toward the application of iPS technology for
clinical purposes.
