Effects of Prempro™ on proliferation of human breast cancer MCF-7 but not MCF-10A cells. MCF-7 (ER+/PR+) and MCF-10A (ER−/PR−) cells were treated with 0, 1, 2, 5, and 10 µg/cm2 of Prempro™ in 10% FBS α-MEM medium in a 96-well plate for 48 h. One µg/cm2 of Prempro™ equals to 10−8 M E2 and 3.3 × 10−8 MPA in culture media. *Significantly different from control, p < 0.05.
