Abstract
Differentiated cells can be reprogrammed to an embryonic-like state by transfer of nuclear contents into oocytes or by fusion with embryonic stem (ES) cells. Little is known about factors that induce this reprogramming. Here, we demonstrate induction of pluripotent stem cells from mouse embryonic or adult fibroblasts by introducing four factors, Oct3/4, Sox2, c-Myc, and Klf4, under ES cell culture conditions. Unexpectedly, Nanog was dispensable. These cells, which we designated iPS (induced pluripotent stem) cells, exhibit the morphology and growth properties of ES cells and express ES cell marker genes. Subcutaneous transplantation of iPS cells into nude mice resulted in tumors containing a variety of tissues from all three germ layers. Following injection into blastocysts, iPS cells contributed to mouse embryonic development. These data demonstrate that pluripotent stem cells can be directly generated from fibroblast cultures by the addition of only a few defined factors.
Comment in
Yamanaka Factors
Yamanaka Factors[4][5] Are a set of 4 transcription factors when introduced into cells induces stem cell formation. These four transcription factors can be expressed from doxycycline (dox)-inducible lentiviral vectors.
OCT4
- Transcription factors containing the POU homeodomain
- Links: OMIM - OCT4
SOX2
- Sry-related HMG-Box gene 2
- Links: OMIM - SOX2
KLF4
- Kruppel-like factor 4, zinc finger protein, transcription factor which acts as both an activator and repressor.
- Links: OMIM - KLF4
cMyc
- The MYC protooncogene encodes a DNA-binding factor that can activate and repress transcription.
- Ectopic expression of c-Myc can also cause tumorigenicity in offspring.
- Links: OMIM - MYC
- More recently shown that Oct4 together with either Klf4 or c-Myc is sufficient to generate iPS cells from neural stem cells.[6]
- Tbx3 transcription factor significantly improves the quality of iPS cells.[7]
