Decidualization is estrogen dependent in the WT but not in the ERKO. (A) WT and ERKO mice were given the hormonal regimen described above with the addition of the antiestrogen ICI 182–780 each day. Uteri (Lower) were traumatized as described. (B) WT and ERKO mice were treated as described in Fig. 4 with the omission of estrogen at each injection. Both uteri shown were traumatized as described.
