Uterine receptivity to implantation varies among species, and involves changes in
expression of genes that are coordinate with attachment of trophectoderm to uterine lumenal …

The majority of pregnancy loss in ruminants occurs during the first three weeks after
conception, particularly during the period of conceptus elongation that occurs prior to …

In cattle, elevated concentrations of circulating progesterone (P4) in the immediate
postconception period are associated with advanced conceptus development, while low P4 …

This study sought to determine the earliest response of the bovine uterine endometrium to
the presence of the conceptus at key developmental stages of early pregnancy. There were …

Bidirectional communication between the developing conceptus and endometrium is
essential for pregnancy recognition and establishment in ruminants. We dissect the …

In cattle, the majority of pregnancy loss can be attributed to early embryonic loss which
occurs prior maternal recognition of pregnancy on Day 16 (Day 0= ovulation). During this …

Gonadal sex differentiation proceeds by the interplay of various genes including the
transcription factors and secretory factors in a complex network. The sex-differentiating …

The objective of the present study was to determine how low progesterone (P4) affects the
endometrial transcriptome, with specific emphasis on those changes that may impact …

This review integrates established and new information on the biological role of ovarian
progesterone (P4) and interferon tau as well as conceptus-and endometrial-derived factors …

Interferon tau (IFNT), a type I IFN similar to alpha IFNs (IFNA), is the pregnancy recognition
signal produced by the ruminant conceptus. To elucidate specific effects of bovine IFNT and …
