We identified two main groups of luminal-type and basal-type breast cancer cell lines by unsupervised Pearson correlation of breast cancer cell lines and intrinsic subtyping. Supervised analysis on spindle versus non-spindle breast cancer cell lines identified a spindle cell signature of 1,144 genes identifying all spindle, basal-type, E-cadherin methylated breast cancer cell lines. Breast cancer cell lines were grown to optimal cell densities for RNA extraction and hybridization on Affymetrix microarrays.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-16795", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-16795/samples/"}
