Abstract
The editors of Tissue Engineering were informed by an external peer reviewer about potential fraud with two similarly published articles in 2014 in Tissue Engineering: Part A, and again in 2015 in the Journal of Materials Science: Materials in Medicine. The two published articles are:
Wu Z, Fan L, Xu B, Lin Y, Zhang P, Wei X. Use of decellularized scaffolds combined with hyaluronic acid and basic fibroblast growth factor for skin tissue engineering. Tissue Eng Part A. 2015;21(1–2):390–402. DOI: 10.1089/ten.tea.2013.0260. Epub 2014 Oct 14. Wu Z, Tang Y, Fang H, Su Z, Xu B, Lin Y, Zhang P, Wei X. Decellularized scaffolds containing hyaluronic acid and EGF for promoting the recover of skin wounds. J Mater Sci Mater Med. 2015;26(1):5322. DOI: 10.1007/s10856-014-5322-1.
Signs of scientific misconduct were found in both articles. In brief, the same images were used in both articles, claiming to show different treatment conditions. Further, the same image was used in different magnifications, again stating that it shows different treatment conditions. Lastly, there appeared to be potential evidence that images were manipulated by cutting, copying, and pasting elements from one image to another.
The editors of Tissue Engineering brought this issue to the attention of the authors, but were not satisfied by their response. As a result, the editorial leadership of Tissue Engineering have determined that a retraction is required in order to protect the integrity of the literature.
In 2015, Dr. Wei published another paper in Tissue Engineering entitled, “Promoting the Recovery of Injured Liver with Poly (3-Hydroxybutyrate-Co-3-Hydroxyvalerate-Co-3-Hydroxyhexanoate) Scaffolds Loaded with Umbilical Cord-Derived Mesenchymal Stem Cells, published in volume 21, number 3–4, which is also being retracted separately based on the potential evidence of image manipulation.
Tissue Engineering, its editors, and its publisher are committed to upholding the strictest standards of the scientific record and the community it serves.
