Mammalian Placentation: A Tribute to E.C. Amoroso’s Contributions to Placenta Development
Establishment of viviparity in mammals evolved through not only the long-term retainment of the fetus within the maternal uterus but differentiation and expansion of cell layers to form functional membranes to...

Chapter
Implantation and Placentation in Ruminants
In comparison to many other mammalian species, ruminant ungulates have a unique form of placentation. Ruminants initially display an epitheliochorial type of placentation; however, during the period of placent...

Open AccessActivation of the transcription factor, nuclear factor kappa-B, during the estrous cycle and early pregnancy in the pig
Establishment and maintenance of pregnancy in the pig involves intricate communication between the develo** conceptuses and the maternal endometrium. This process occurs during trophoblast elongation which i...

Article
Open AccessTrophoblast biology: Forum introduction
In mammals, a carefully orchestrated dialogue between the mother and conceptus (embryo/fetus and associate extraembryonic membranes) is initiated during the peri-implantation period of pregnancy as the trophob...

Article
Open AccessConceptus signals for establishment and maintenance of pregnancy
Establishment and maintenance of pregnancy results from signaling by the conceptus (embryo/fetus and associated extraembryonic membranes) and requires progesterone produced by the corpus luteum (CL). In most m...

Open AccessEffects of the estrous cycle, pregnancy and interferon tau on expression of cyclooxygenase two (COX-2) in ovine endometrium
In sheep, the uterus produces luteolytic pulses of prostaglandin F2α (PGF) on Days 15 to 16 of estrous cycle to regress the corpus luteum (CL). These PGF pulses are produced by the endometrial lumenal epithelium ...

Cytokines and Pregnancy Recognition
Maternal recognition of pregnancy results from signaling between the trophoblast of the conceptus (embryo and associated membranes) and the maternal system (1). These signals ensure maintenance of the structur...
