TE inhibits cancer stem cells. (A) 410.4 or 66.1 cells plated in low attachment conditions and primary tumorspheres allowed to form in the presence of TE or PBS control. On day 10, tumorspheres were dissociated, and size expressed as cells per sphere. P values: *P < .01; **P < .0002; ***P < .00005; ****P < .000007. (B) 410.4 tumorspheres treated with vehicle or TE, tumorspheres harvested (day 8), dissociated and fraction of ALDH1 + cells determined. *P < .06. Fraction of ALDH1 + cells in secondary 66.1-derived tumorspheres. *P < .004; **P < .002. PBS indicates phosphate-buffered saline; TE, taro extract.
