Higher resolution figures to be added

Posted by timangel on 05 Oct 2013 at 17:21 GMT

To everyone interested in our work, thanks. We have noticed that the quality of the photomicrographs in the current online version are not representative of the fine detail of the originally submitted figures, and thus may lead readers to incorrect conclusions. We are working with the post-production team to upload the original, higher resolution images. We appreciate your interest and your patience and hope that you will view the manuscript with the new images.
