The objectives of this study were to characterize changes in transcriptome of preimplantation
conceptuses at the onset of elongation and associated changes in uterine histotroph …

Elongation of the preimplantation conceptus is a prerequisite for successful pregnancy in
ruminants and depends on histotroph secretion by the endometrium. Lipids are an essential …

Studies support the idea that uterine epithelia and their secretions have important biological
roles in conceptus survival, elongation, and implantation in sheep. The present study …

This review integrates established and new information on the factors and pathways
regulating conceptus–endometrial interactions, conceptus elongation and establishment of …

Background During the preimplantation phase in the pig, the conceptus trophoblast
elongates into a filamentous form and secretes estrogens, interleukin 1 beta 2, interferons …

The porcine conceptus undergoes rapid differentiation and expansion of its trophoblastic
membranes between Days 11 and 12 of gestation. Concomitant with trophoblast elongation …

Conceptus elongation coincides with one of the periods of greatest pregnancy loss in cattle
and is characterized by rapid trophectoderm expansion, commencing~ Day 13 of …

Background We hypothesized that genes that are up-regulated in the uterine endometrium
at the initiation of conceptus elongation in cattle, and that encode for secreted proteins …

Modifications of the endometrial transcriptome at day 7 of the estrus cycle are crucial to
maintain gestation after transfer of in vitro-produced (IVP) embryos, although these changes …

This review integrates established and new information on the role of progesterone,
interferon tau (IFNT), and prostaglandins in uterine biology of ruminants. Establishment of …
