“…The mouse uterus is able to distinguish an implanting embryo from an artificial deciduogenic stimulus by reactions of specific proteins (Weitlauf & Suda-Hartman, 1988). In addition to proteins, other factors including steroids, prostaglandins and histamines have been proposed as messengers in a communication between the uterus and the embryo (reviewed by Heap et ai, 1979;Sauer, 1979;Kennedy, 1983). Genetic variation in the production or release of such mediators may also influence timing of pre-implantational events.…”

Mice with high and low prenatal survival were used to study the influence of maternal and embryonic genotype on the timing of implantation, conceptus growth and gestation length. Mice selected for large litter size (Line S1) or rapid post-weaning weight gain (Line G) showed implantation was delayed and gestation prolonged in mice with low prenatal survival (Line G). Reciprocal transfer of Line-S1 and -G embryos to pseudopregnant recipients indicated that conceptus growth was influenced by maternal as well as embryonic genes, at least until mid-pregnancy. In contrast, fetal genotype had a major effect on the length of gestation.

“…In most species studied, females ovariectomized in early pregnancy can maintain pregnancy if given only progesterone. Other species, including the mouse, rat, gerbil and lemming, require addition of oestrogen to allow embryo implantation (reviews, Sauer, 1979;Levasseur, 1984). In some carnivorous species such as the ferret, pregnancy has not been maintained with exogenous progesterone and oestrogen combinations after ovariectomy (Foresman & Mead, 1978).…”

“…Much of this work has been done using mated females ovariectomized after ovulation and given exogenous hormones to maintain pregnancy (reviews, Sauer, 1979;Levasseur, 1984). In these studies, the uterus has been influenced by endogenous hormones before and during the oestrus immediately preceding pregnancy.…”

“…Cortisol concentrations were essentially equal in ES and CS (Fig. 3) (Sauer 1979), whereas increasing E, concentrations prior to parturition are responsible for several factors directly related to myometrial activity: increased myosin and actin protein content within the myometrium gap junction formation (Garfield et al 1980), and synthesis and replenishment of high affinity oxytocin binding sites on the uterus (Soloff et al 1979 Sows allowed to exercise during gestation farrow piglets that are more viable at birth than piglets of confined sows, thereby increasing potential annual productivity.…”
