Indole-3-Carbinol Induces Apoptosis in Human Osteosarcoma MG-63 and U2OS Cells

Figure 3

I3C suppresses the colony-forming ability of MG-63 and U2OS cells. The number of colonies was determined by the colony formation assay. (a) MG-63 (100 cells/well) and U2OS (250 cells/well) were treated with I3C (200 and 400 μM) or the control (DMSO) for 1 day and media was replaced with fresh media (DMEM, 10% FBS, 1% antibiotics). After 2 weeks, the cells were stained with crystal violet solution. Representative images of colony formation assays are shown. (b) The number of colonies in I3C-treated wells was compared with that of the control group. The number of colonies was counted and the results were analyzed statistically using Student’s t-test. = p<0.05.
