RETRACTED: Bone marrow-derived mesenchymal stem cells-secreted exosomal microRNA-192-5p delays inflammatory response in rheumatoid arthritis

Abstract

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. Concern was raised about the reliability of the Western blot results in Figures 2D, 3E and 4E, which appear to have a similar phenotype as contained in many other publications, detailed here: https://pubpeer.com/publications/7C4BCEFA1DB0FE34826962595A5C9C; and here: https://docs.google.com/spreadsheets/d/1r0MyIYpagBc58BRF9c3luWNlCX8VUvUuPyYYXzxWvgY/edit#gid=262337249. Although no Western blot duplications were identified within this article, when this article was compared with ‘Jin, Ren & Qi (2020)’™, mentioned in the PubPeer thread, two suspected image duplications were identified within Figure 5B. We confirmed that the histological sections represent different treatment groups from different papers as discussed in the PubPeer thread. The journal requested the corresponding author comment on these concerns and provide the raw data. The authors did not respond to this request and therefore the Editor-in-Chief decided to retract the article.
