Basal-like breast cancer contains greater levels of cancer stem cells than luminal/neu breast cancer. (A) Representative Western blot of cell lysate for HIF-1α (I) and Tubulin (II). Relative pixel density ± SD as measured by densitometry from 3 independent experiments (III), **p<0.05. (B) Percent of Sca-1 expressing cells in the indicated cell line. ****p<0.0001; n=4 independent experiments. (C) Representative Western blot of Sca-1positive and Sca-1negative cell lysate for HIF-1α (I) and Tubulin (II). Relative pixel density ± SD as measured by densitometry from 3 independent experiments (III), **p<0.01.
