Assessment of how misidentified cell lines were used in 162 articles in The International Journal of Cancer (guidelines implemented in 2010, stringent since 2011) (A) and 107 articles in Blood (no guidelines) (B) as identified by applying the Web of Science search string of Horbach and Halffman. In which we distinguished articles in which a misidentified cell line was used while being aware of the misidentification (green), articles in which a misidentified cell line was used but the cell line was of the same tissue type (blue) and articles in which a misidentified cell line of a different tissue type was used while being unaware of it (red). For the last two categories, we distinguished between articles that used a misidentified cell line before it was first reported to be misidentified (light blue and light red) and after it was first reported to be misidentified (dark blue and dark red) [Color figure can be viewed at wileyonlinelibrary.com]
