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...

Regulation of Endometrial Responsiveness to Estrogen and Progesterone by Pregnancy Recognition Signals During the Periimplantation Period
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 structural a...

Uterine Glands
This chapter focuses on the comparative development and mechanisms regulating branching morphogenesis of endometrial glands in the mammalian uterus. All uteri contain endometrial glands that secrete substances...

The Evolutionary Interplay Between Exogenous and Endogenous Sheep Betaretroviruses
Sheep betaretroviruses represent an interesting model to study the complex evolutionary interplay between host and pathogen in natural settings. In infected sheep, the exogenous and pathogenic Jaagsiekte shee...

Implantation and Establishment of Pregnancy in Ruminants
The establishment of pregnancy in ruminants occurs during the peri-implantation period and involves the suppression of the endometrial luteolytic mechanism to maintain progesterone production by the corpus lut...

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...

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...
