This article presents methods for the isolation and culture of epithelial cells from the bovine oviduct for use in both research and the teaching laboratory and provides examples of ways that an oviductal cell culture can be incorporated into an undergraduate research program. Cow reproductive tracts are readily available from area butchers, and the procedure for isolation of the epithelium is ...

The baboon oviductal epithelium differentiates into a tall columnar epithelium consisting of ciliated and secretory cells during the follicular phase of the menstrual cycle in response to rising oestradiol levels. The apical tips of these secretory cells are filled with membrane-bound secretory granules. During the luteal phase when progesterone levels are elevated, the epithelium regresses and...

Summer heat stress (HS) negatively affects reproductive functions, including prostaglandin (PG) F2α secretion in the endometrium, and decreases fertility in cattle. In the present study, we examined the effects of elevated temperatures on PG synthesis in oviductal epithelial cells. The epithelial cells obtained from the ampulla and isthmus of the oviduct were incubated at various temperatures (...

This study examined the effect of the presence of single or multiple embryos on the transcriptome of the bovine oviduct. In experiment 1, cyclic (nonbred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells fro...

The Chinese brown frog (Rana dybowskii) is a special amphibian with one unique physiological phenomenon, which is that its oviduct expands prior to hibernation, instead of during the breeding period. In this study, we investigate the localization and expression level of PPARγ2, leptin and leptin receptor proteins in oviduct of Rana dybowskii during  breeding period and pre-hibernation. There we...

Background and purpose: Ëmbryo co-culture systems with somatic cells have been a subject of extensive study as valuable tools to promote embryo in vitro development. The aim of this study was to evaluate, the Ëffects of a special kind of co-culture system in which somatic cells were cultured as polarized monolayer on mouse embryo development. Materials and methods : Human oviduct was obtai...

High-grade serous carcinoma (HGSC) is the most lethal ovarian cancer histotype. The fallopian tube secretory epithelial cells (FTSECs) are a proposed progenitor cell type. Genetically altered FTSECs form tumors in mice; however, a spontaneous HGSC model has not been described. Apart from a subpopulation of genetically predisposed women, most women develop ovarian cancer spontaneously, which is ...

Oviductal sperm storage tubules (SST), located at the uterovaginal junction, are the primary site of sperm storage in turkeys. Sperm reside within these storage sites and may be released via a dynamic interaction between sperm mobility and a fluid current generated by the SST epithelial cells. In this study, aquaporins 2, 3, and 9 (proteins that form water channels in the plasmalemma of a varie...

objective: helicobacter pylori has a well-established role in the development of gastric cancer. in vitro studies reveal increased proliferation of the gastric mucosa in the presence of h. pylori infection. it has been also shown that production of some cytokines, such as interleukin-1 beta (il-1b) is increased in h. pylori infection. in addition, il-1b increases proliferation of gastric epithe...

The oviductal microenvironment is a site for key events that involve gamete maturation, fertilization and early embryo development. Secretions into the oviductal lumen by either the lining epithelium or by transudation of plasma constituents are known to contain elements conducive for reproductive success. Although previous studies have identified some of these factors involved in reproduction,...
