Tissue-level phase transitions are emerging as a crucial mechanism in tumour development and metastasis. When becoming invasive, epithelial tumours undergo a transition from a solid-like state to a more fluid-like one. Although the contributions of cell adhesions, traction forces and cell migration for such behaviour are known, the exact biophysical and molecular mechanisms controlling these tran…

In the version of the article initially published, the scale bar in Fig. 3d was labelled "Proton density (10 -5 -3 )" and read (from top to bottom) "1.0, 0.5, 0" but should have been labelled "Proton density (10 -1 -3 )" and have read (from top to bottom) "1.7, 0.7, 0".In the Fig.
