Stemness signature: a set of genes which are upregulated in induced cancer stem cells (iCSCs), and enriched in embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). These genes represent a stem cell state. Non-stemness signature: a set of genes which are upregulated in iCSCs, but are not associated with the stemness signature. Stemness “ON”: a set of breast cancer tumor samples which have significant enrichment in the stemness signature. Stemness “OFF”: a set of breast cancer tumor samples which do not have enrichment of the stemness signature.
