Regeneration of atretic sheep ovarian follicles in vitro.
Large (4--6 mm diam.) and small (2--3 mm) atretic follicles were removed from sheep ovaries during the luteal phase of the cycle and maintained in organ culture without hormonal supplementation for up to 5 days. The structure, cell dynamics and steroid-producing capacity of the follicles were compared with those of non-atretic follicles of similar size. The granulosa layer of the atretic follic...
متن کاملO-13: Gene Expression Pattern of Adiponectin and Adiponectin Receptors in Bovine Dominant and Non-Dominant Follicles
Background: Recent studies have revealed that adiponectin, a novel adipocytokine, and its two receptors (AdipoR1 and AdipoR2) are involved in regulation of ovarian function in various farm animal species. The aim of this study was to investigate the gene expression pattern of Adiponectin and its receptors in ovarian cells of dominant (DFs) and non- dominant follicles (NDFs) in the bovine. Mater...
متن کاملGlobal gene expression in granulosa cells of growing, plateau and atretic dominant follicles in cattle
BACKGROUND The physiological state of the dominant follicle is important as it may be linked to the competence of the oocyte within. The objective of this study was to analyze, by transcriptomic analysis, the changes occurring in granulosa cells from dominant follicles at different phases of follicular growth. METHODS Granulosa cells were collected from slaughterhouse dairy cattle follicles w...
متن کاملSteroid hormone formation in bovine ovarian follicles.
In an attempt to assess histophysiological implication of the follicular compartment of the bovine ovary in steroid hormone formation and the effect of human chorionic gonadotropin (hCG) in vitro on follicular steroidogenesis, minces of follicular tissues from non-gravid bovine ovaries were incubated with radioactive testosterone or acetate in the presence and absence of hCG. Significant amount...
متن کاملFas and Fas ligand protein and mRNA in normal and atretic mouse ovarian follicles.
Apoptosis is the underlying mechanism of follicular atresia in the mammalian ovary. However, the apoptotic pathways governing this ovarian process are not completely elucidated. In the present study, expression of Fas and Fas ligand, the proximal members of the death receptor pathway, was evaluated in mouse ovarian follicles using immunofluorescence and in situ hybridization. Normal or atretic ...
