Growth Differentiation Factor-9 Mediates Follicle-Stimulating Hormone-Thyroid Hormone Interaction in the Regulation of Rat Preantral Follicular Development

O-20: The Combination of Basic Fibroblast Growth Factor and Follicular Stimulating Hormone Promotes Human Follicle Development In Vitro Culture

Background Fertility preservation is an important part of scientific study in the field of reproductive medicine. Ovarian cryopreservation and in vitro follicles culture provide option for fertility conservation in older women or cancer patients. Basic fibroblast growth factor (bFGF) or FGF-2, is member of fibroblast growth factors family which play critical roles in cell migration proliferatio...

Growth differentiation factor 9 promotes rat preantral follicle growth by up-regulating follicular androgen biosynthesis.

The transition from preantral to early antral stage is the penultimate stage of ovarian follicular development in terms of gonadotropin dependence and follicle destiny. Although oocyte-somatic cell communication is important in early follicular development, our knowledge of the precise role of the oocyte-derived growth differentiation factor (GDF)-9 during preantral follicle growth is incomplet...

Follicular development in heifers infused with follicle-stimulating hormone.

Follicle-stimulating hormone from different species has been used to increase ovulation and calving rates in cattle, injections proving to be most successful when given during the late follicular phase of the oestrous cycle or in combination with progestagens (Willett & Buckner, 1953; Bellows, Anderson & Short 1969). Some investigations have resulted in substantial increases in ovulation and ca...

The Correlations of Anti-Mullerian Hormone, Follicle-Stimulating Hormone and Antral Follicle Count in Different Age Groups of Infertile Women

Thyroid hormone regulation of the transfected rat growth hormone promoter.

A region of the rat growth hormone gene and 5' flanking DNA has been identified which promotes accurate, thyroid hormone-regulated transcriptional initiation. GC rat pituitary tumor cells were transfected with chimaeric plasmids containing various lengths of rat growth hormone gene and 5' flanking DNA fused to the coding region of the dominant selectable marker gene neo. Thyroid hormone inducti...
