Cell-type specificity of regulatory elements identified by linker scanning mutagenesis in the promoter of the chicken lysozyme gene [PDF]

open access: yes, 1989
The chicken lysozyme gene is constitutively expressed in macrophages, in oviduct cells its expression is controlled by steroid hormones, and in fibroblasts the gene is not expressed.

Deciphering the oviductal extracellular vesicles content across the estrous cycle: implications for the gametes-oviduct interactions and the environment of the potential embryo

open access: yesBMC Genomics, 2018
The success of early reproductive events depends on an appropriate communication between gametes/embryos and the oviduct. Extracellular vesicles (EVs) contained in oviductal secretions have been suggested as new players in mediating this crucial cross ...

CDC42 governs normal oviduct multiciliogenesis through activating AKT to ensure timely embryo transport

open access: yesCell Death and Disease, 2022
Ciliated and secretory cells are two major cell types that comprise the oviduct epithelia. Accumulating evidences support a role of oviductal multiciliated epithelia for embryo transport, however the mechanisms underlying this specialized cell type ...

OVIDUCT SECRETION IN THE COW [PDF]

open access: yesReproduction, 1970
Little is known regarding the physiological role of oviduct fluid on ova and spermatozoa in the reproductive tract. VanDemark (1958) and Bishop (1961) suggested that luminal fluids may be an important transport and nutrient medium for the gametes; others felt that oviduct secretions influenced sperm activity (Olds & VanDemark, 1957a) or aided the ...

Analysis of pregnancy outcome after anastomosis of oviduct and its influencing factors

open access: yesBMC Pregnancy and Childbirth, 2019
Background This study aims to investigate the influencing factors of pregnancy after laparoscopic oviduct anastomosis. Methods The data of 156 cases of laparoscopic oviduct anastomosis in our hospital were analyzed.

Oviduct: roles in fertilization and early embryo development.

open access: yesJournal of Endocrinology, 2017
Animal oviducts and human Fallopian tubes are a part of the female reproductive tract that hosts fertilization and pre-implantation development of the embryo.

The Known and Unknown About Female Reproductive Tract Mucus Rheological Properties. [PDF]

open access: yesBioessays
Mucus viscosity changes as spermatozoa travel through the female reproductive tract to the egg in humans, bovines, mice, and other mammals. These changes may aid in spermatozoa navigation. However, limited information is available on the viscoelastic properties of female reproductive tract mucus, and consistent measurement techniques are lacking ...

Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]

open access: yes, 2014
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

The physiological significance of insemination in programming pregnancy outcome [PDF]

open access: yes, 2006
The cellular and molecular environment of the uterus during the pre - and peri - implantation period of early pregnancy is critical for implantation success and optimal fetal and placental development.
