Confirm that someone has successfully created STAP stem cells

The Japan Institute of Physical Chemistry Research (Riken) on April 14 said that someone who is not the co-author of a controversial research paper creating STAP stem cells has successfully performed the production. STAP multi-function cell, after the lead author Haruko Obokata made a similar statement last week.

>>>Suspects copying around STAP cell works

An official of Riken's public relations department said: 'Some people who are not co-authors of the essay confirmed the work with "flexible" genes. However, it is not a complete copy (of STAP) and does not support Ms. Obokata's argument. "

The leading author of a paper on multipurpose cells published in the January 2014 issue of Nature's scientific journal opposed Riken's April 1 conclusion that she made a mistake and fabricated some points. in this thesis on breakthrough breakthrough STAP cells.

The 30-year-old researcher said her research group has been more than 200 times successful in producing STAP cells whereby she and other researchers involved in the study said it could develop into immature What tissue on the mouse body.

Obokata said, Riken has admitted that the person who successfully created STAP cells but she did not give the name of the person at the press conference on 9 April.

The researcher admitted that he cut and pasted the research results, but said her findings were still valid and she would not agree to withdraw the research paper.

Riken plans to make a decision later this week about whether to re-investigate the thesis as requested by Obokata.

If the institute dismissed her objection, Riken's conclusion would be the final step in the investigation process and Riken might decide the discipline for Obokata.

On April 14, Obokata issued a statement through his lawyer and confirmed that she "produced STAP cells almost every day and usually several times a day".

Ms. Obokata asserted in the statement that STAP cells were produced more than 100 times until September 2011 and more than 100 times later in her experiments.
