Effect of CMs from hATN and hATT on proliferation of MCF-10A, HBL100, MCF-7 and IBH-7 cells. MCF-10A, HBL100, MCF-7 and IBH-7 cells were incubated with hATN- (n = 10), hATT- (n = 12) or control-CMs 48 h, at 50% or 75% CM. Proliferation was measured by MTS assays. Data are shown as the mean ± SEM (n = 5–7 experiments by triplicate). *p < 0.001 hATT-CMs vs. hATN-CMs or control-CMs (50% CMs); ^# p < 0.001 hATT-CMs vs. hATN-CMs or control-CMs (75% CMs); **p < 0.05 50% hATT-CMs vs. 75% hATT-CMs
