Since January, scientists around the world have tried unsuccessfully to recreate the surprising discovery of stem cells simply targeted adult cells can turn into powerful stem cells, which are similar to those found in early embryos. Now science Insider has learned that a number of laboratories involved in the production of two documents describing the work does not try to imitate the technology before the documents were made public. Only two laboratories involved in the paper saying they could produce cells called loss.The controversy was there for about two months, when the scientific stem Haruko Obokata suddenly became a media sensation in Japan. took place 30 years ago when he and his colleagues published two articles in the journal Nature described a new and surprisingly simple way to create stem cells that scientists talk about the acquisition of pluripotent cells (STAP) which is triggered by stimuli .Now Obokata still in the spotlight, but the script has changed. Allegations that documents containing recover photos Ph. D. thesis Obokata, among others, fueled doubts about the requirements. And since research has increased, many workers, scientists have confirmed that they have not yet produced STAP cells either.It was not unusual for the offender to perform most of the paperwork, says Martin Pera, research on stem cells at the University of Melbourne in Australia. But as revolutionary and simple techniques had to be, he said, repeating the uncertainty is confusing.Previous methods to get pluripotent stem cells, the cells use all appreciate the possible role of the necessary regeneration to reduce embryos or adults to force the cells overwhelms the gene. But the article and letter in Nature online on January 29 Obokata and colleagues at Riken Developmental Biology Center (Riken CDB) in Kobe, Japan, in Japan and other institutions in the United States and is described in the a surprisingly simple options. All that was needed to make pluripotent stem cells, they reported briefly bathed baby mouse cells slightly acid solution, then refine culture conditions.After several days of questions about the pictures in the two documents began appearing on blogs and on top of PubPeer. Tokyo umbrella Riken CDB, Research Riken started February 13 allegations of these and previous paper Obokata continues to grow.On March 14, the President and other Riken governments announced the first results at a press conference room in Tokyo. Riken President Ryoji Noyon and Nobel Prize began with a profound rescue event. ‘I’m sorry for a lot of anxiety and worry caused so Riken researchers in the business records published in Nature, he said.The committee said it was incorrect processing of data ‘for products covered by the investigation, but they were’ not proven the lack of investigation, ‘according to the press release Riken short. But officials stressed that they trust the scientific community finally determine the STAP cells can be treated by the method described Obokata and colleagues. Information is whether there is an error; Stap cells if there is something of the scientific community to decide, the president said committee Shunsuke Ishii, a molecular geneticist at Riken, during a press conference, which lasted a marathon four hours. He added that, to the best of his knowledge, no one outside the group reported success in producing STAP cells.
