Abstract
Following the publication of the above article, an interested reader drew the authors' attention to the fact that certain features shown in Fig. 6B, illustrating the tumors extracted from the animal in vivo experiments, were strikingly similar to images that had appeared in other papers by different authors published at around the same time. The authors conceded that the in vivo experiments reported in this study had been performed by a third party. Therefore, in the interests of preserving accuracy in the scientific record, the authors requested that this paper be retracted from the Journal. The Editor is in agreement that the paper should be retracted. All authors agree with the retraction of this article, and the Editor apologizes to the readership for any inconvenience caused.
