Breast cancer cells, plated at 1×105 cells per well in 6-well plates in 2 ml of DMEM/F12 medium containing 5% FBS, were treated with JS-K for 3 days and stained with acridine orange. The red fluorescence in the acridine orange-stained cells was detected by flow cytometry.
MDA-MB-468 and HMEC cells, plated at 4×105 cells per well in 6-well plates in 2 ml of HMEC medium containing bovine pituitary extract, were treated with JS-K for 3 days and stained with acridine orange. The red fluorescence in the acridine orange-stained cells was detected by flow cytometry.
MCF-10A cells, plated at 4×105 cells per well in 6-well plates in 2 ml of DMEM/F12 medium containing 10% FBS, 20 ng/ml epidermal growth factor, 20 ng/ml insulin-like growth factor-I, and 500 ng/ml hydrocortisone, were treated with JS-K for 3 days and stained with acridine orange. The red fluorescence in the acridine orange-stained cells was detected by flow cytometry.
