RETRACTION: Exosomes Derived From Adipose Tissue, Bone Marrow, and Umbilical Cord Blood for Cardioprotection After Myocardial Infarction

Abstract

RETRACTION: H. Xu, Z. Wang, L. Liu, B. Zhang, and B. Li, “Exosomes Derived From Adipose Tissue, Bone Marrow, and Umbilical Cord Blood for Cardioprotection After Myocardial Infarction,” Journal of Cellular Biochemistry 121, no. 3 (2020): 2089-2102. https://doi.org/10.1002/jcb.27399.

The above article, published online on 17 November 2019, in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Christian Behl; and Wiley Periodicals LLC. A third party reported to the publisher that several images in the article included panels with overlapping samples. Those overlapping panels are as follows: Figure 1C and 1D have overlapping panels for BMMSC and ADMSC; Figure 2B has an overlapping panel between the Normal and Sham samples; and Figures 4B, 4C, and 4G each have several overlapping panels, several of which included rotated sections. In addition, the third party reported that several images in Figure 4C had been reused from a previously-published article by a different group of authors [Chen et al. 2018 (https://doi.org/10.2147/dddt.s163405)]. An investigation by the publisher confirmed each instance of image duplication and that several of the images had been re-used from the earlier paper. The retraction has been agreed to because the evidence of image duplication and manipulation compromises the integrity of the study and the conclusions presented in the article. The authors did not respond to an inquiry by the publisher.
