Retraction of: Scientific Reports https://doi.org/10.1038/srep09787, published online 10 April 2015

The Editors have retracted this Article.

After the publication, the first author reached out to the Editors to point out that that the phase contrast microscopy image in Figure 3(b) appears to replicate panels that originally appeared in Figure 2(b) of1, which reports a different experiment by different authors. When asked by the Editors, the Authors were not able to provide the raw data and stated that the images in Figure 3(b) were obtained through a third party hired to perform some of the experiments for this study. Given the concerns about the veracity of the data, the Editors no longer have confidence in the results and conclusions presented in this Article.

All Authors agree to this retraction.
