A group of researchers in Japan who study oral stem cells has lost at least nine papers for fabricated data.
We reported on this group, from Aichi Gakuin University in Nagoya, last year after they lost two papers in PLOS ONE for image manipulation. The new retraction notice appears in the Journal of Oral Biosciences, an Elsevier journal, and refers to several other papers that the editors say are to be retracted.
This article has been retracted at the request of the Authors. After the retraction of the article [Hiyama T, Ozeki N, Mogi M, Yamaguchi H, Kawai R, Nakata K, Kondo A, Nakamura H. 2013. Matrix Metalloproteinase-3 in Odontoblastic Cells Derived from Ips Cells: Unique Proliferation Response as Odontoblastic Cells Derived from ES Cells. PLoS ONE 8(12): e83563. https://doi.org/10.1371/journal.pone.0083563] which contained fabricated/falsified data, the authors attempted to confirm original data for the results presented in their related publications. As a result, they reached a conclusion that there were no original data for the results presented in several their publications. This article was written on the basis of the seven publications retracted or to be retracted and it is no longer reliable. …
All of the authors except Nobuaki Ozeki have agreed to retract the article. Nobuaki Ozeki, the corresponding author and the first author of the article, left Aichi Gakuin University in March 2018, and does not respond to co-authors inquiries.
