Time-course effect of mifepristone withdrawal on cancer cells of the ovary (A), breast (B), prostate (C), and nervous system (D). Cells were seeded at a density appropriate for exponential growth for each cell line, allowed to adhere for 24 h, and then exposed to the previously determined cytostatic concentrations of mifepristone for 72 h. Thereafter mifepristone-containing media was replaced with normal growth media and images were taken using phase contrast microscopy after 0, 24, 48 or 72 h (A-D). Scale bar = 50 μm.
