Lu’s work builds on the Nobel Prize winning discovery of Shinya Yamanaka, who identified the four transcription factors, Oct4, Sox2, Klf4, c-Myc, that could erase epigenetics markers on cells and return these cells to their primitive embryonic state from which they can develop into any other type of cell.

The Yamanaka factors are a set of 4 genes (named Myc, Oct3/4, Sox2 and Klf4) that when turned on in a mature cells (like a skin cell) can force the cell to ‘de-differentiate’ back into an immature cell that is capable of becoming any kind of cell.

1 level 1 efficiently deliver the Yamanaka factors to somatic cells, including blood, in just one overnight incubation. The 2.0 version offers: • The highest reprogramming efficiency, for more colonies than other reprogramming technologies • Lower cytotoxicity to allow for smaller starting cell populations Dr. Goya’s team is currently exploring Yamanaka factors in relation to aging. These factors (Oct3/4, Sox2, Klf4, c-Myc) are the four master genes that allow cells to be rejuvenated and reprogrammed [1]. In 2011, Jean-Marc Lemaitre famously reset cells from people aged over 100 back to the state of a 20-year-old’s cells [2]. They started with 24 and narrowed it down to just four factors: Oct4, Sox2, Klf4, and cMyc,(2) now known as OSKM or Yamanaka factors.

We showed that induced pluripotent stem (iPS) cells can be generated from mouse embryonic fibroblasts (MEF) and adult mouse tail-tip fibroblasts by the retrovirus-mediated transfection of four transcription factors, namely Oct3/4, Sox2, c-Myc, and Klf4 (. Takahashi and Yamanaka, 2006. 2016-12-15 2021-03-23 "This is evidence of how teamwork between computational and bench biologists can lead to exciting discoveries. Wysocka notes that there have been observations that sometimes Yamanaka factors like Oct4 have been spotted in cancer cells, and it has been discounted as an inconsequential sign of how dysregulated cancer cells have become.

They started with 24 and narrowed it down to just four factors: Oct4, Sox2, Klf4, and cMyc,(2) now known as OSKM or Yamanaka factors.

Gladstone Institute of Cardiovascular Disease, San Francisco, CA 94158, USA. INTRouCToN John Gurdon received recognition for his landmark achievement in 1962, which provided the lrst experimental evidence of reprogramming by the The four transcription factors of the Yamanaka cocktail (Oct4, Sox2, Klf4, and Myc, termed OSKM) are famously capable of reprogramming somatic cells into induced pluripotent stem cells (iPSCs). 2018-10-17 · SOX2 cooperates with other endogenous core factors of pluripotency, such as Oct3/4 and Nanog, by occupying the target loci of these factors, thus forming a stable pluripotency circuit in iPSCs. If true, then factors besides OSKM should be able to reprogram the cell if they bind to the appropriate loci and stabilize the requisite circuitry. 2020-12-02 · Second, the factors could reset the cellular state to the most primitive cell state, thus completely erasing a cell’s identity. Lu and colleagues circumvented these hurdles by slightly modifying the approach. They dropped the gene c-Myc and delivered only the remaining three Yamanaka genes, Oct4, Sox2, and Klf4.

While the technique reliably creates iPS cells, it can cause unintended effects, some of which can lead to cells to become cancerous. Based on this hypothesis, three groups of potential pluripotency‐inducing factors have been selected (Takahashi & Yamanaka 2006).

Little is known about factors that induce this reprogramming.

The reprogramming factors turn off or turn on gene expression at these spots accordingly. After successfully generating mouse iPSCs, Yamanaka and Takahashi began a similar search for the reprogramming factors that would create human iPSCs. Amazingly, they discovered that the same four genes worked to convert human skin cells into stem cells.

Unfortunately, while some compounds could induce Oct4 expression, the key iPSC transcription factors and the other Yamanaka factors could not be replaced by a single set of small molecules.

When activated, skin cells from mice could be reprogrammed to immature stem cells, which, in turn, can grow into different types of cells within the body. These so-called Yamanaka factors, named after biologist Shinya Yamanaka, are widely used to generate induced pluripotent stem cells (iPSCs). In a 2016 Cell paper, a different group of scientists had activated these transcription factors in mice with progeria, a condition that causes premature aging, and found that the treatment alleviated symptoms and extended their lifespan by a matter of weeks.
