Trait Constellation
Key Achievements
In 2006, with Kazutoshi Takahashi, he showed that introducing just four genes turns mature mouse cells into pluripotent stem cells, which he named iPS cells.
He shared the 2012 Nobel Prize in Physiology or Medicine with John Gurdon for the discovery that mature cells can be reprogrammed to become pluripotent.
In 2007 his lab reported human iPS cells, on the same day as James Thomson's lab with a different gene set, and from 2008 he led Kyoto University's Center for iPS Cell Research and Application toward clinical use.
Moments That Reveal Them
He introduced all 24 candidate ES-cell genes into skin cells at once; colonies appeared only with the full mixture, and Takahashi then narrowed them to four factors.
This is consistent with a willingness to run a bold, all-at-once experiment on a long-shot idea. Creative Originality
In June 2011 he presented data from ten embryonic and fifty iPS cell lines to answer critics, conceding that some iPS lines do differ from embryonic stem cells.
This is consistent with answering criticism with data rather than denial. Analytical Rigour
Turning Points
After residency as an orthopaedic surgeon he left surgery for a pharmacology PhD in 1989 and a mouse-genetics postdoc in San Francisco, a path that led to stem-cell research.
This is consistent with a willingness to change fields when he judged he could do more good elsewhere. Adaptability

- Nobel Assembly at Karolinska Institutet, 'The Nobel Prize in Physiology or Medicine 2012 - Press release', read in full. CANONICAL SIGNIFICANCE SOURCE: the prize was awarded jointly to John B. Gurdon and Shinya Yamanaka 'for the discovery that mature cells can be reprogrammed to become pluripotent'; Gurdon showed in 1962 that specialisation is reversible by nuclear transfer in frogs, and Yamanaka discovered more than 40 years later, in 2006, how intact mature mouse cells could be reprogrammed to stem cells by introducing only a few genes. An award-body summary: admiring and retrospective.
- Nobel Committee for Physiology or Medicine, 'Scientific Background: Nuclear Reprogramming' (Advanced information, Nobel Prize in Physiology or Medicine 2012), read in full for the Yamanaka section: his earlier Nanog and Eras work, the choice of 24 ES-cell transcription factors tested in one step, narrowing to Myc, Oct3/4, Sox2 and Klf4 (Takahashi and Yamanaka 2006), the absence of germ-line transmission in the first study and its achievement a year later by Yamanaka's group in parallel with the Jaenisch and Hochedlinger groups, and the 2007 human iPS cells from Yamanaka's and James Thomson's laboratories using different factor combinations. A committee text: authoritative, careful about priority and parallel work, admiring in tone.
