The Less Differentiated Luminal Epithelia in Gp130d/d and Stat3d/d Females Are Associated with Heightened Uterine Estrogenic Responses without Altered Ovarian Hormone Levels. A, Immunostaining of Ki67 in implantation sites on day 4 of pregnancy. Arrowheads indicate Ki67-positive luminal epithelial cells. B and C, Serum levels of E2 and P4 on day 4. D, Immunostaining of MUC1 (red) at the day 4 implantation sites. Nuclei are stained with Hoechst dye (blue). Le, luminal epithelium; Myo, myometrium; S, stroma.
