The role of endothelin-2 in ovulation
… granulosa and theca cells of an ovulating follicle luteinize and form lutein cells of the highly vascular corpus luteum, which secrete progesterone for pregnancy maintenance. Just prior to ovulation, the gene endothelin-2 (Edn2) is highly yet transiently expressed for a two-hour window. …

Investigating the role of ephrins and their receptors in mouse folliculogenesis and ovulation
Follicle stimulating hormone (FSH) promotes granulosa cell (GC) proliferation, differentiation, and steroidogenesis. This series of events is critical for female fertility, and culminates in the formation of mature follicles responsive to the surge of luteinizing hormone (LH) that triggers …

PGE2 Receptor Subsets Mediate HCG Regulation of the Plasminogen Activator/Plasmin System in Primate Periovulatory Follicles
… prostaglandin E2 (PGE2) levels are necessary for follicle rupture during ovulation. As the degradation of the follicle wall requires proteolysis, it was hypothesized that regulation of proteolysis by gonadotropins is PGE2 mediated.</p> <p>There are four PGE2 receptors: EP1, EP2, EP3 and EP4. To …

MORPHOLOGICAL FEATURES OF THE REPRODUCTIVE ORGANS IN DOMESTIC SPECIES IN RELATION TO WATER MOVEMENT CONTROL, HYPONUTRITION AND ENVIRONMENTAL INFLUENCES IN FETAL AND PREPUBERTAL LIFE, AND METABOLISM REGULATOR FACTORS.
… The shortest pathway for water to reach the follicle antral cavity is the transcellular pathway directly through the cytoplasm of granulosa cells. In this first experiment we have considered the functional presence of Hg2+-sensitive Aqps in isolated granulosa cells assessing changes in cell …
