Abstract:
This study was designed to investigate the inhibitory effect of supernatant from co-culture of human embryonic stem cells and tumor MDA-MB-231 cells on the breast cancer. The direct co-culture system of human embryonic stem cells H9 and breast cancer MDA-MB-231 cells was established, and the supernatant was tested in the inhibition of MDA-MB-231 cells. The inhibitory effects were examined in tumor cell morphology using microscope, cell proliferation with MTT assay, and cell apoptosis using the Hoechst staining and flow cytometry. Transwell assay was used to detect the migration and invasion of tumor cells. The results suggest that the supernatant significantly inhibited the proliferation, invasion and migration, and promoted cell apoptosis of MDA-MB-231 cells. However, the supernatant of H9 cells alone had little effect on MDA-MB-231 cells. Therefore, we conclude that the supernatant of co-culture cells had an inhibitory effect on tumor cells in vitro.
