KP signals specifically via KISS1R in the uterus on D4 of pregnancy in WT mice. Phosphorylated p38 expression in the D4 pregnant uterus following 30 min PBS pre-treatment followed by 30 min PBS post-treatment (a); part of the uterus shown in (a) is magnified to better reveal details on the endometrial glands (b). Phosphorylated p38 expression in the D4 pregnant uterus following 30 min PBS pre-treatment followed by 30 min KP54 post-treatment (c); part of the uterus shown in (c) is magnified to better reveal details on the endometrial glands (d). Phosphorylated p38 expression in the D4 pregnant uterus following 30 min P234 pre-treatment followed by 30 min KP54 post-treatment (e); part of the uterus shown in (e) is magnified to better reveal details on the endometrial glands (f). AM: anti-mesometrial pole; LM: longitudinal muscle of the myometrium; CM: circular muscle of the myometrium; E: endometrium; LE: luminal epithelium; GE: glandular epithelium; M: mesometrial pole; UL: uterine lumen
