We, the Editors and Publishers of Brain Injury, have retracted the following article:
Zhuobo Zhang, Dongmei Jin, Zichao Yang, Baozhong Shen & Ming Liu (2011) Effects of 17β-estradiol pre-treated adult neural stem cells on neuronal differentiation and neurological recovery in rats with cerebral ischemia, Brain Injury, 25:2, 227-236, DOI: 10.3109/02699052.2010.542430
Since publication, concerns were raised about the integrity of the histology images within Figure 2A. Upon investigation it was discovered that the histology images had previously been published in the following article within Figure 1, representing results of different experimental conditions:
Li-qun Fang & Zhuo-bo Zhang (2010) Brca-1 gene-regulated neural stem cells transplantation in treatment of cerebral infarction, Journal of Clinical Rehabilitative Tissue Engineering Research, 14:45 DOI: 10.3969/j.issn.1673-8225.2010.45.017
When consulted, the authors confirmed that the same images had been used in both articles and confirmed there are integrity issues present in both articles. We have informed the authors that their article is to be retracted due to these integrity issues.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
