(A) The ALDH1-positive subpopulation varies between human BC cell lines according to the distinct molecular subtypes. Basal/epithelial and HER2 overexpressing protein cell lines exhibit strong ALDH1 activity. The mean of two independent experiments is plotted. (B) Subpopulations of CD44+/CD24−/low cells in human BC cell lines according to the distinct molecular subtypes. Basal-like cell lines are mainly constituted of cell populations with a high level of CD44 and a low level of CD24. The mean of three independent experiments is plotted. ALDH1, aldehyde dehydrogenase 1; HER2-OE, human epidermal growth factor receptor 2-overexpressing; CD, cluster of differentiation.
