K. Yumoto characterized the primary normal cells and dormant cancer cells, evaluated the cytotoxicity of copolymer to normal cells and dormant cancer cells, and prepared cell samples for SEM. K. Yasuhara performed the lipid vesicle assays. E.T.N. synthesized and characterized the copolymers. Y.K. supervised the assays using primary normal cells. L.B. devised and supervised the development of cell lines to monitor dormancy. R.S.T. devised the project and supervised the assays using dormant cancer cells. K.K. devised the project, helped with data analysis, and prepared the manuscript. All authors assisted with editing the manuscript.” These errors have now been corrected in the PDF and HTML versions of the Article, and in the accompanying Supplementary Information file.
