Retraction to: Nature Communications https://doi.org/10.1038/s41467-018-07998-x published online 10 January 2019

The authors have retracted this article due to multiple imaging errors across several figures which call into the reliability of the data and the conclusions. In particular, we note there were errors in the colony formation images (Fig. 1j, Fig. 1l, 5j), migration images (Fig. 1i, 1h, 2h, 5h), western blots (Fig. 2e, Fig. 6a) and histology (Supplementary Fig. 4a). In addition, at the time of publication some experiments were lacking biological repeats (Fig 2e, 2h, 5h, 5j, 6a) We apologise for any inconvenience caused to the community. Qingling Zhang has stated on behalf of all authors that they agree to this retraction.
