Quality control of cell lines used in biomedical research is essential to ensure reproducibility. Although cell line authentication has been widely recommended for many years, misidentification, including cross contamination, remains a serious problem. We outline a multi-stakeholder, incremental approach and policy-related recommendations to facilitate change in the culture of cell line authentication.

Across different fields of cancer research, up to a third of all cell lines have been identified as impostors. Yet this fact is widely ignored, and the lines continue to be used under their false identities.

A substantial proportion of cell lines is mislabeled or replaced by cells derived from a different individual, tissue or species. The scientific community has failed to tackle this problem and consequently thousands of misleading and potentially erroneous papers have been published using cell lines that are incorrectly identified. Recent efforts to develop a standard for… Read more »
