The Biggest Fraud in Stem Cell History

In 2014, the world of science was shaken by an unprecedented fraud. So, what really happened to shatter the dreams of a Nobel Prize and became a dark chapter for stem cell research? This is the story of STAP cells. 🔬 Subscribe for more awesome biomedical research: https://bit.ly/2SRMqhC 📸 IG: instagram.com/clemens.steinek 🔬Twitter:   / csteinek   Let’s set the scene. It’s the early 2000s. Japan has become a powerhouse in stem cell research. Stem cells are cells that form our bodies during development. Back in the day, stem cells could only be isolated from embryos. In 2006, Yamanaka and Takahashi demonstrated how we can make stem cells from skin cells. Through the introduction of 4 genes (oct4, sox2, klf4, c-myc) they converted skin cells into pluripotent stem cells. For this discovery, Yamanaka later won the Nobel Prize in Physiology or Medicine. Haruko Obokata was a japanese scientists who tried to develop another method to make stem cells. She teamed up with Charles Vacanti who theorized that stem cells can be made through stress. When Obokata bathed body cells in mild acid, she claimed to have produced stem cells. She refined this method and STAP cells were born. Later, they approached Teruhiko Wakayama and Yoshiki Sasai. Both helped them and in 2013 "STAP Cells" were finally published. In the first weeks, STAP cells seemed like a huge success. But the scientific community soon discovered manipulations in the presented images. RIKEN, the institute where Obokata was hosted launched an internal investigation. They concluded that the STAP cell works have to be retracted and Obokata lost her position. RIKEN had to undergo reconstruction due to the lasting public outcry which ultimately affected everyone involved. Today, STAP cells are considered as one of the biggest scandals in stem cell research. 00:00-3:35 The Japanese Stem Cell Wonder 3:35-7:53 Fabricating the Discovery of the Century 7:53-13:10 How Everyone Found Out 13:10-15:37 The Devastating Aftermath References: Brilliant Article: https://www.newyorker.com/magazine/20...
