Progesterone and implanting blastocysts regulate Muc1 expression in rabbit uterine epithelium.
Mammalian uteri are unreceptive to blastocyst implantation except during a relatively brief period. The transmembrane, cell surface mucin, Muc1, is present on epithelial cells of nonreceptive uteri in various species and has been demonstrated to have antiadhesive properties. These activities of Muc1 may prevent interaction of the embryonic trophoblast cells with the uterine epithelium. A previo...
متن کاملThe culture of mouse blastocysts in the presence of uterine flushings collected during normal pregnancy, delayed implantation and pro-oestrus.
When day-3 mouse embryos were cultured in a simple medium supplemented with uterine fluids of mice autopsied on day 4 of pregnancy, 48 h after administration of oestradiol, or during pro-oestrus, the percentage of blastocysts hatching from the zona pellucida was significantly greater than in unsupplemented medium. In the presence of uterine fluids recovered during delayed implantation this stim...

On the orientation of the implanting blastocyst.
In viviparous mammals the implanting blastocyst is positioned according to a number of parameters which are species specific. First, in polytocous animals the blastocysts become spaced out along the length of the uterus, secondly they take up a particular relationship to the circumference of the endometrium, and lastly the embryonic pole always assumes a constant orientation to the mesometrial-...
متن کاملEffect of sequential implanting with zeranol on steer lifetime performance.
Three trials involving 513 exotic crossbred steers were conducted to determine the effect of zeranol implanting in the suckling and growing phases on subsequent feedlot performance and carcass characteristics. Treatments were 1) unimplanted control, 0000; 2) implanted twice in the finishing phase, 00II; 3) implanted in the growing phase and twice in the finishing phase, 0III; 4) implanted in th...
