Migration of interphase arrested cells is inhibited by ESE-15-one and ESE-one exposure. a MDA-MB-231 cells were first blocked in G1/S by exposure to thymidine before cell free zones were generated and cells were exposed to 0.2% DMSO, 0.5 μM ESE-15-one or 0.5 μM ESE-one. Cell migration into the cell-free zone was quantified after 18 h. The graph represents the average of at least three repeats with error bars representing SEM. *P < 0.001 in t-test comparison with DMSO-treated cells. b Light microscopy images of cell migration assays showing interphase cells at time 0 h and after 18 h treated with DMSO, ESE-15-one or ESE-one. Scale bar is 400 μm
