Stem cell scientist's appeal against misconduct verdict rejected

12 May 2014

By Purvi Shah

Appeared in BioNews 753

Japan's RIKEN Center has announced that an appeal by stem cell scientist, Dr Haruko Obokata, found guilty of research misconduct in relation to her claims of converting blood cells to stem cells using an 'acid bath', has been rejected.

Allegations of data fabrication and plagiarism surfaced around two research papers that reported a simple way of creating stem cells using a technique the researchers called STAP (stimulus-triggered acquisition of pluripotency) (reported in BioNews 740).

A misconduct panel found that Dr Obokata, who was the lead author of the papers, had reused an image from her thesis and had produced an image of DNA analysis spliced together from two separate pictures (BioNews 740).

Dr Obokata publicly apologised last month (BioNews 740), claiming the errors were due to carelessness.  However, she defended her research findings and refused to retract her papers, calling for a reinvestigation. RIKEN has declined to re-open the investigation, however.

President of RIKEN, Ryoji Noyori, said in a statement: 'RIKEN has decided not to re-investigate the allegations of research misconduct. The appellant has been notified of this decision, and has been advised to retract the one paper which was found to have instances of research misconduct'.

Dr Obokata is unable to file any further formal appeals and RIKEN will now decide what course of action to take against her and the other researchers involved. Penalties can vary from pay cuts, suspension from work and forced resignation.

Dr Shinichi Aizawa, a special advisor to RIKEN, is currently leading a group to begin efforts into verifying the results of the STAP experiments. To date no one has been able to reproduce the same results and outcomes that were supposedly achieved by Dr Obokata.

RIKEN has instructed its primary scientists to review all of their papers, reports Nature News, which says that four members of the misconduct panel are now themselves facing allegations of irregularities in their published work.
