RETRACTED: Neural Stem Cells Engineered to Express Three Therapeutic Factors Mediate Recovery from Chronic Stage CNS...

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the editor-in-chief. Similarities were found between images in this article and a previously published article in Scientific Reports (Zhang et al., 2015, Sci. Rep. 30, 17407, https://doi.org/10.1038/srep17407). Similarities were also found between images within this article. These concerns were initially reported in a PubPeer thread (https://pubpeer.com/publications/11D757FEEACDC81ACAF60BD0A32607). Image analysis performed by the editorial office confirmed findings of image reuse in Figures 2C and 5C of the Molecular Therapy article. In addition, some of the original data provided by the authors do not match the published article. This reuse (and in part misrepresentation) of data without appropriate attribution represents a severe abuse of the scientific publishing system. The authors disagree with this retraction and maintain that these mistakes do not alter the conclusions of the study.
