Announcement: Time to tackle cells' mistaken identity. Nature 16 April 2015;520:264
This Editorial sets out new ways to tackle the problem of misidentified cell lines. Changes apply to all Nature journals from 1st May 2015. Authors of papers involving cell lines are asked to check their cell lines against publicly available lists of known misidentified cell lines. If the authors use a known problematic cell line, they are asked to provide a scientific justification for its use, and clearly state its identity in the Methods section.
Authors must report on a cell line's source, authentication testing, and Mycoplasma testing status. For authentication testing, authors are asked to state the test method, test result, and when testing was last performed.
