Mechanisms of angioregression of the corpus luteum

open access: yesFrontiers in Physiology, 2023
The corpus luteum is a transient ovarian endocrine gland that produces the progesterone necessary for the establishment and maintenance of pregnancy. The formation and function of this gland involves angiogenesis, establishing the tissue with a robust ...

New Aspects of Corpus Luteum Regulation in Physiological and Pathological Conditions: Involvement of Adipokines and Neuropeptides

open access: yesCells, 2022
The corpus luteum is a small gland of great importance because its proper functioning determines not only the appropriate course of the estrous/menstrual cycle and embryo implantation, but also the subsequent maintenance of pregnancy.

Angiogenesis in the corpus luteum [PDF]

open access: yesReproductive Biology and Endocrinology, 2003
The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual ...

The Role of the Guanosine Nucleotide-Binding Protein in the Corpus Luteum

open access: yesAnimals, 2021
The corpus luteum is a temporary endocrine gland in the ovary. In the ovarian cycle, repeated patterns of specific cellular proliferation, differentiation, and transformation occur that accompany the formation and regression of the corpus luteum ...

Synchronization with estradiol benzoate in the presence of the corpus luteum in Wagyu cows increases the number of medium follicles but does not interfere with in vitro production of embryos

open access: yesSemina: Ciências Agrárias, 2021
Reproductive biotechnologies emerge as an important element for livestock, however, some strategies must be modified to adapt the different breeding systems, such as the use of follicular synchronization protocols.

Expression of leptin and leptin receptor transcript in ovine corpus luteum [PDF]

open access: yesIranian Journal of Veterinary Medicine, 2018
Background: Leptin, the product of the obesity (ob) gene, acts as a signaling adipokine for modulating food intake, energy metabolism and reproductive functions in mammals. Leptin’s effects on the reproductive system at various levels of the hypothalamic-
