MYC and breast cancer: BCSphCs display an enrichment, at different ratio, in stem-like CD44high/CD24low subpopulation and express high levels of other stem cell markers such as MYC and VIMENTIN (Supplementary Fig. SlA–D), suggesting that this cell compartment has a phenotype closer to mammary basal-myoepithelial stem cells, as compared with BC luminal and TNBC cell lines [23].
