The cell lines within the NCI-60 panel of human tumor cell lines are perhaps some of the most extensively characterized cell lines in broad laboratory use. These data are publicly available on the DTP web site at: http://dtp.cancer.gov/mtargets/mt_index.html
Of particular interest to those concerned about cell line identity, the cell lines have been characterized using ~120,000 SNP arrays (1) and by oligonucleotide-base HLA typing (2). Mutations in a number of cancer-relevant genes have been analyzed in these cell lines (3). They have also been subjected to spectral karyotyping (data available at: http://www.ncbi.nlm.nih.gov/projects/sky/) (4). The lines have also been characterized for variations in short tandem repeats (STR) (5), although there are some technical issues in applying this technology, which was developed as a forensic tool, to cancer cell lines. In particular, polyploidy and/or increased mutation rates that are characteristics of some of the cell lines may require adjustments in interpretation of STR data. Additional characterization of the NCI-60 panel will be posted periodically.
Previous analyses (esp. the SNP arrays and HLA typing) have shown
that several pairs of cell lines within the NCI60 panel are from the
same individual. STR profiling also finds these cell lines to be
"matched pairs". The data point to events early in the derivation of
these cell lines - it appears that the versions of these cell lines
in use throughout the research community are the same as the
versions in the DTP collection. For a further discussion of these
cell lines, please see:
In addition to these methods of cell line characterization, data from numerous other studies are available for these cell lines through the DTP web site at http://dtp.cancer.gov/mtargets/mt_index.html.
