Figure 6. Neutralization of estrogenic effects by ICI improves diapause in Foxa2f/fLtfCre+ and Foxa2f/fPgrCre+ mice.

Figure 6.

(a) Scheme of ICI treatment. Foxa2f/fLtfCre+ and Foxa2f/fPgrCre+ mice were treated with leukemia inhibitory factor (LIF) (20 μg) on day 8. Pregnancy was evaluated on day 10, 2 days after LIF administration. (b) Representative photographs of uteri in Foxa2f/fLtfCre+ and Foxa2f/fPgrCre+ mice with ICI treatment 2 days after LIF administration. Foxa2f/f mice have normal day 10 implantation sites, suggesting implantation occurs under 25 μg ICI treatment in Foxa2f/f mice. Scale bar: 10 mm. Histological pictures of implantation sites in panel b were presented in panel c. Scale bar: 500 μm. (d) Average number of implantation sites in Foxa2f/fLtfCre+ and Foxa2f/fPgrCre+ mice with ICI treatment. Numbers and percentage on bars indicate mice with implantation sites over total number of mated mice. (e) Litter sizes of Foxa2f/fLtfCre+ and Foxa2f/fPgrCre+mice with ICI treatment. Numbers and percentage on bars indicate mice with pups over total number of mated mice.
