Breast cell lines (MDA-MB-231, MDA-MB-468, MCF7 and T47D) and primary human breast cancer cells were live cell sorted by FACS. Cells were sorted by ESA +/−, then CD44+/−, then CD24 lo/high to gain CD44+/24lo/ESA+ (Stem-like cells) and CD44-/24hi/ESA- (Non stem-like cells). These populations were sorted according to cell cycle (Hoechst DNA profile) into G0/1 and S/G2/M, and for comparison the whole cell population (all). (A) mammosphere formation assayed +/− DKK1 (50ng/ml) (Black bars). Bar charts represent the % mammosphere formation, ±SEM. p values were generated using a two sided t-test assuming equal variance. * indicates significance, p<0.05
