Correction to: Nature Communications https://doi.org/10.1038/ncomms8353, published online 2 July 2015.

This Article contains an error in Fig. 7. In Fig. 7a, the image for in-b1-5p is inadvertently duplicated from the in-b1-3p image.

When preparing the correction the authors noticed that the images incorrectly represent an invasion experiment rather than a migration experiment. New images have been provided for both in-b1-5p and in-b1-3p.

Representative images for three independent migration assays have been provided as Supplementary Fig. 1.

The error has not been corrected in the PDF or HTML versions of the Article.
