Extracellular matrix regulates ovine granulosa cell survival, proliferation and steroidogenesis: relationships between cell shape and function.
The extracellular matrix (ECM), constituting the follicular basal lamina and present also between follicular cells and in the follicular fluid, is believed to regulate granulosa cell (GC) function during follicular development. Ovine GCs isolated from small (1-3 mm in diameter) or large (4-7 mm in diameter) antral follicles were cultured on various pure ECM components (type I collagen, fibronec...
متن کاملBisphenol A disrupts steroidogenesis in human H295R cells.
There is increasing concern over the risk of environmentally relevant doses of bisphenol A (BPA) on human endocrine systems. Effects of BPA on steroidogenesis and the related molecular mechanisms were investigated in H295R human adenocarcinoma cells. This immortal cell line is unique in expressing all the enzymes of the steroidogenic pathways. The effects of BPA on steroidogenesis, 17β-estradio...
متن کاملRegulation of Apoptosis and Steroidogenesis in Ovarian Preovulatory Granulosa Cells
Only a minute fraction of ovarian follicles present in a foetal ovary will complete the path to ovulation. The majority of the follicles will instead undergo atresia, a hormonally controlled apoptotic process. Apoptosis occurs throughout follicle development, with an extensive reduction in the number of follicles present at birth. Interestingly, this drastic reduction is not present among preov...
متن کاملRegulation of Proliferation and Steroidogenesis in Human Granulosa Cells
Background and Aims:Human follicles selected for further development are thought to receive precise signals from gonadotropins and locally produced growth factors for survival. In this experiment, the mechanisms of the regulation of proliferation and steroidogenesis by GDF-9 and Br-cAMP in human ovarian cells were investigated. Methods:SVOG cells were cultured and treated with GDF-9 and Br-cAMP...
متن کاملEffect of adiponectin on bovine granulosa cell steroidogenesis, oocyte maturation and embryo development
BACKGROUND Adiponectin is an adipokine, mainly produced by adipose tissue. It regulates several reproductive processes. The protein expression of the adiponectin system (adiponectin, its receptors, AdipoR1 and AdipoR2 and the APPL1 adaptor) in bovine ovary and its role on ovarian cells and embryo, remain however to be determined. METHODS Here, we identified the adiponectin system in bovine ov...
