Abstract:

We sought to identify altered oviductal protein secretions in response to the presence of gametes in the oviduct in vivo at the time of ovulation. Experiments were designed to compare oviductal fluid from a gamete-stimulated oviduct to a non-gamete-stimulated oviduct within the same animal. Clips were introduced at the infundibulum of both oviducts to prevent oocytes from entering the oviducts and one uterine horn was cut to prevent sperm access to that oviduct. Sows were artificially inseminated the next day with diluted boar semen. Control sows that had undergone the same surgical procedures

Abstract:

The oviduct plays important roles in reproductive events: sperm reservoir formation, final gamete maturation, fertilization and early embryo development. It is well known that the oviductal environment affects gametes and embryos and, ultimately, the health of offspring, so that in vivo embryos are better in terms of morphology, cryotolerance, pregnancy rates or epigenetic profile than those obtained in vitro. The deciphering of embryo–maternal interaction in the oviduct may provide a better understanding of the embryo needs during the periconception period to improve reproductive efficiency.

Abstract:

The equine oviduct plays a pivotal role in providing the optimal microenvironment for early embryonic development, but little is known about the protein composition of the oviducal fluid in the horse. The aim of the present study was to provide a large-scale identification of proteins in equine oviducal fluid and to determine the effects of ovulation and pregnancy. Four days after ovulation, the oviducts ipsilateral and contralateral to the ovulation side were collected from five pregnant and five non-pregnant mares.

Previous experiments have shown that boar sperm survival in vitro is enhanced when co-incubated with a solubilised protein extract of porcine oviducal apical plasma membrane proteins.

We have also examined the effectiveness of mechanical scraping as a method of recovering oviducal epithelial proteins. We show that a subset of proteins origin

Abstract:

The oviduct is a complex and organized thin tubular structure connecting the ovary with the uterus. It is the site of final sperm capacitation, oocyte fertilization and, in most species, the first 3–4days of early embryo development. The oviductal epithelium is made up of ciliary and secretory cells responsible for the secretion of proteins and other factors which contribute to the formation of the oviductal fluid. Despite significant research, most of the pathways and oviductal factors implicated in the crosstalk between gametes/early embryo and the oviduct remain unknown. Therefore, studying

A systematic study was performed on animals at four different stage: prepubertal gilts, and sows in the preovulatory, postovulatory and luteal phase of the oestrous cycle.

Abstract:

Sperm hyperactivation is characterised by high-amplitude, asymmetrical flagellar bending and is required to penetrate the oocyte zona pellucida. It was proposed that hyperactivation also enables spermatozoa to reach the oocyte by assisting escape from the oviductal sperm reservoir. To test this hypothesis, the behaviour of CatSper-null mouse spermatozoa in the oviduct was compared with that of spermatozoa from heterozygotes. CatSper–/– males are infertile because their spermatozoa fail to hyperactivate, whereas spermatozoa from CatSper+/– males have normal amounts of CatSper proteins and can h

The oviduct and uterus undergo extensive cellular remodelling during the oestrous cycle, requiring finely tuned intercellular communication. Notch is an evolutionarily conserved cell signalling pathway implicated in cell fate decisions in several tissues. In the present study we evaluated the quantitative real-time polymerase chain reaction (real-time qPCR) and expression (immunohistochemistry) patterns of Notch components (Notch1–4, Delta-like 1 (Dll1), Delta-like 4 (Dll4), Jagged1–2) and effector (hairy/enhancer of split (Hes) 1–2, Hes5 and Notch-Regulated Ankyrin Repeat-Containing Protein (

The bovine embryo develops in contact with the oviductal fluid (OF) during the first 4–5 days of pregnancy. The aim of this study was to decipher the protein interactions occurring between the developing embryo and surrounding OF. In-vitro produced 4–6 cell and morula embryos were incubated or not (controls) in post-ovulatory OF (OF-treated embryos) and proteins were then analyzed and quantified by high resolution mass spectrometry (MS) in both embryo groups and in OF. A comparative analysis of MS data allowed the identification and quantification of 56 embryo-interacting proteins originated f

Abstract:

Expression of transcription factors binding to the activating protein-1 (AP-1) site is induced by estrogens in association with epithelial proliferation in the uterus, but, in the oviduct, the relationship between cell proliferation and differentiation and AP-1 transcription factors is not well understood. In the developing rat oviduct, we found that proliferation and differentiation of epithelial cells were region-dependently regulated by 17beta-estradiol (E2). To determine the role of AP-1 transcription factors in the development of rat oviduct, we performed immunohistochemistry for epitheli

Oviductal epithelial cells (OECs) actively produce stimulating and protecting factors, favoring survival and viability of gametes and early embryos. The oviduct participates in the initial reproductive events, which strongly depends on adhesion. The analysis of differential gene expression in OECs, during long-term in vitro culture, enables recognition of new molecular markers regulating several processes, including “biological adhesion”. Porcine oviducts were stained with hematoxylin and eosin, as well as with antibodies against epithelial markers. Then, OECs were long-term in vitro cultured

Abstract:

In mammals, the oviduct (or the Fallopian tube in humans) can be divided into the infundibulum (responsible for oocyte pick-up), ampulla (site of fertilization), isthmus (where preimplantation embryos develop), and uterotubal junction (where embryos transit to the uterus). The oviductal fluid, as well as extracellular vesicles produced from the oviduct epithelial cells, referred to as oEVs, have been shown to improve the fertilization process, prevent polyspermy, and aid in embryo development. oEVs contain molecular cargos (such as miRNAs, mRNAs, proteins, and lipids) that can be delivered and

Abstract:

Spermatozoa undergo several modifications in the oviduct before acquiring fertilising capacity. Although spermatozoa are exposed to similar conditions in the oviduct, the speed of the response varies with the male and the state of the spermatozoa. We hypothesised that spermatozoa from bulls with different fertility may differ in their ability to respond to oviductal fluid (ODF). Frozen–thawed spermatozoa from four bulls were incubated with oestrus oviductal fluid (OODF) for 6 h.

Abstract:

The reproductive tract in avian females is sensitive to hormonal regulation. Exogenous estrogen induces immature oviduct development to improve egg production after molting. In this process, regressed female reproductive tract is regenerated in response to the secretion of estrogen. However, there is limited knowledge on the physiological mechanisms underlying the regulation of the avian female reproductive system. In our previous study, results from microarray analysis revealed that the expression of genes encoding egg white proteins is affected during molting. Herein, we artificially induced
