A former star scientist with the government-backed Riken research institute who was accused of research fraud after the debunking of high-profile work on STAP cells in 2014 is ready to tell her side of the story.

In a book relating her ordeal, Haruko Obokata insists she was at least partially successful in creating cells that have the potential to turn into any kind of body tissue.

"I sincerely apologize for causing a huge uproar to society, following the publication of papers on STAP cells," she writes in the book's foreword. "I truly feel miserable and sorry for not being able to offer my heartfelt regret and apology to the public. ... But I think I would choose to become a researcher again if I am allowed to start my life all over."
