Cross-contamination and misidentification of cell lines are unfortunately very common within the research community. Many contaminated cell lines were overgrown by the contaminating cell line during establishment and so authentic stocks probably do not exist; in those cases all work has been performed on the contaminant, which may come from a different species, tissue or cell type.
Cell line cross-contamination was first discovered in the 1960s and has been extensively reported since that time. Contaminated or misidentified cell lines have also been listed on the websites of individual cell banks. To make it easier to check for these references, a single list has been developed summarising the cell lines known to be affected, their contaminants, and the references used. The list was developed and is maintained by Dr R. Ian Freshney and Dr Amanda Capes-Davis.
