BACKGROUND Amitraz, an insecticide used to prevent tick and mite infestation of cattle, crops and dogs, is an alpha2-adrenergic receptor agonist that inhibits GnRH release and the ovulatory LH surge in rats. Noradrenalin, the physiological ligand for

As an endocrine organ, the ovary has some unique characteristics. The formation, the maturation and the regression of the hormone producing cells really determine the timing, the amount and the type of hormone secreted. Here, we focus on the granulos

We have previously postulated that granulosa cells of developing follicles arise from a population of stem cells. Stem cells and cancer cells can divide indefinitely partly because they express telomerase. Telomerase is a ribonucleoprotein enzyme tha

Granulosa cell death is an early feature of atresia; however, there are many apparent contradictions in the literature concerning the mode of granulosa cell death. We have therefore examined this process in bovine healthy and atretic antral follicles

During follicular development the proliferative and differentiated state of the epithelioid granulosa cells changes, and the movement of fluid across the follicular basal lamina enables the formation of an antrum. Type IV collagen is an important com

Myeloid leukaemia inhibitory factor (LIF) is expressed at highest concentrations in the maternal endometrial glands at about the stage of blastocyst implantation. LIF is also expressed by the extraembryonic membranes of the early mouse embryo. Embryo

During ovarian folliculogenesis granulosa cells divide while in contact with stromal cells and other granulosa cells. Following ovulation, however, they cease dividing and differentiate into large luteal cells. When cultured in monolayer, granulosa c

OBJECTIVES: To investigate (1) whether type 3 17β-hydroxysteroid dehydrogenase (17β-HSD), the enzyme which catalyzes the conversion of androstenedione to testosterone in the testis, is co-expressed with P450aromatase in the preadipocytes of women,

The cellular biology and changes in the extracellular matrix of ovarian follicles during their development are reviewed. During growth of the bovine ovarian follicle the follicular basal lamina doubles 19 times in surface area. It changes in composit
