Editorial Expression of Concern to: Nature Communications https://doi.org/10.1038/ncomms2282, published online 18 December 2012
The Editors would like to alert the readers that concerns have been raised regarding the data presented in Figs. 1 and 5. Specifically:
-
Fig. 1e (MTX-MP 72 h) and Fig. 5a (First) appear similar;
-
Fig. 1f (Control) and Fig. 5a (Control) also appear to overlap.
The authors have stated that the errors occurred due to similar morphology of the presented groups, and have been able to replicate the results described in the article. However, due to the age of the article, the original data are no longer available. Readers are therefore advised to interpret these results with caution.
