We analyzed serum samples from 60-day-old offspring euthanized between 0800 (1 hr after lights on) and 1500 hours (6 hr before lights out), in the diestrus stage of the estrous cycle, for PRL, LH and TSH, and we analyzed anterior pituitaries for PRL and LH by radioimmunoassay, as previously described by Cooper et al.

Therefore, to better understand the role of ALCAM at the fetal-maternal interface in pigs during pregnancy, we determined i) the pattern of ALCAM expression in the uterine endometrium during the estrous cycle and pregnancy; ii) localization of ALCAM mRNA in the uterine endometrium; iii) effects of steroid hormones on ALCAM mRNA expression; and iv) ALCAM expression levels in the uterine endometrium from gilts with embryos derived from SCNT compared with those from gilts with embryos from natural mating.
This experiment was conducted to evaluate: 1) eNOS immunolocalization; and 2) co-localization of eNOS and VEGF in ovine CL throughout the estrous cycle.
