Best practices for authenticating cell lines
2017
Nims, RaymondW. | Reid, Yvonne
Experiments using cell cultures are only valid to the extent that the cell culture is a true model system for the biological system being investigated. To assure that a cell line is and remains an appropriate biological model, its identity, purity, ploidy, and phenotype must be maintained. These characteristics comprise and determine the authenticity of a cell line. Routine monitoring of the cell line through microscopic examination of morphology can help to determine authenticity, as can the determination of phenotypic status. Assays designed to confirm cell identity and ploidy and freedom from cross-contaminating cell types may need to be performed at certain times, as such information may not be obtained through morphologic and phenotypic examinations alone. The best practices associated with establishing cell line authenticity are described in this article.
