The current study used RNA sequencing to determine transcriptional profiles of equine endometrium collected 14, 22, and 28 days after ovulation from pregnant mares. In addition, the transcriptomes of endometrial samples obtained 20 days after ovulati

Sixteen cases of spontaneous pregnancy loss (11 of singletons and five of pairs of twins) are described. The losses occurred between gestation Days 13 and 25 in 12 mares being monitored almost daily by transrectal ultrasonography (for measurement of

The main purpose of this autobiographical reminiscence of 40 years of embryo research is to provide young theriogenologists with a firsthand account of how career development can depend strongly on early influences that become modified by changing ci

Tetrapod limb development has been studied extensively for decades, yet the strength and role of developmental constraints in this process remains unresolved. Mammals exhibit a particularly wide array of limb morphologies associated with various loco

Poor survival of cryopreservation by equine expanded blastocysts may involve low penetration of the embryonic capsule by cryoprotective agents (CPAs). This study characterized the permeation and accumulation rates of the CPAs ethylene glycol (EG) and

Summary In the present study, we have investigated the molecular structure and biosynthesis during development of the donkey capsule, which replaces the zona pellucida and envelops the conceptus during the 2nd and 3rd weeks of gestation, before uteri

Estrogen production by the trophoblast is considered important in early equine pregnancy and leads to high concentrations in yolk-sac (Y-S) fluid. The embryo proper is a potential site for their action. We examined estrogen metabolism in the embryo p

A critical period of early gestation in the mare involves the immobilization (fixation) of the encapsulated conceptus at around days 16-17. We compared the major proteins in the normal equine embryonic capsule and endometrial secretions around the pe
