Author Correction: HER2 expression identifies dynamic functional states within circulating breast cancer cells

In the version of this article initially published, representative HER2-stained histology images in Extended Data Fig. 3c, Fig. 4f and Extended Data Fig. 6g were incorrectly assembled. Extended Data Fig. 3c contained two images from the same CTC Brx-82-derived HER2+ tumour; these have been replaced with correct images from the respective CTC Brx-82-derived HER2− and HER2+ xenografts. In Fig. 4f, paclitaxel-treated and post-treatment recovery images were mistakenly sourced from untreated CTC Brx-142-derived tumors; these have been replaced with correct treated (T) and post-recovery (R) images. Extended Data Fig. 6g contained an incorrect post-recovery image. Due to the age of the article, the figures cannot be updated directly. Revised images are available as Supplementary Information accompanying this amendment. This notice serves to correct the article.
