Luteal-phase PF promotes attachment of fully transformed FTE cells whereas FF promotes attachment of all FTE cells. The attachment of RFP-labelled FTE cells to ex vivo-cultured mouse peritoneal tissues after different treatments was examined. The ex vivo culture of the treatment and no-treatment groups of a cell line were performed on the same peritoneum. (a) Representative images of cells attached to the peritoneum after 24 h of culture. Scale bar: 200 μm. (b) Comparison among the treatment groups. Three or more independent experiments were conducted. The asterisk represents a comparison with the vehicle treatment. * p < 0.05, ** p < 0.01, by two-sided, unpaired Student’s t-test
