Professor Shinya Yamanaka describes his back-up plan if his risky stem cell experiments failed

As part of the Nobel Prize Inspiration Initiative in Scandinavia, Nobel Laureate Shinya Yamanaka answered the question: 'Did you always believe that your stem cell experiments would work?'.
Professor Yamanaka visited Norway and Sweden in September 2017. There he met scientists in Oslo and Gothenburg, discussing his career, his work and the ethics of stem cell research.
Through the Initiative, Nobel Laureates offer career advice for scientists, explain their discoveries and give insights into life after the Nobel Prize.
