Although the authors refer to Hep2 as "larynx squamous carcinoma cells", the description is unfortunately not correct. Hep2 is cross-contaminated and is actually HeLa, from cervical carcinoma. For a list of known cross-contaminated or otherwise misidentified cell lines, see http://iclac.org/databases/cross-contaminations/.
