Bone morphogenetic protein-4 acts as an ovarian follicle survival factor and promotes primordial follicle development.
The growth and development of follicles within the ovary are highly dependent on autocrine and paracrine signaling involving growth factors from granulosa cells, theca cells, stromal interstitial cells, and the oocytes. The growth factor bone morphogenetic protein-4 (BMP-4) and its receptor (BMPR-IB) have been detected in ovaries, and a mutation in BMPR-IB has been associated with abnormal ovul...
متن کاملRegulation of primordial follicle assembly and development.
The assembly of the primordial follicles early in ovarian development and the subsequent development and transition of the primordial follicle to the primary follicle are critical processes in ovarian biology. These processes directly affect the number of oocytes available to a female throughout her reproductive life. Once the pool of primordial follicles is depleted a series of physiological c...
متن کاملEstrogen can signal through multiple pathways to regulate oocyte cyst breakdown and primordial follicle assembly in the neonatal mouse ovary.
During mouse embryonic development, oocytes develop in germline cysts, formed by several rounds of cell division followed by incomplete cytokinesis. Shortly after birth, cysts break down and individual oocytes are enclosed by granulosa cells to form primordial follicles. At the same time, two-thirds of the oocytes die by apoptosis with only one-third surviving. We have previously shown that the...
متن کاملGonadotropin treatment augments postnatal oogenesis and primordial follicle assembly in adult mouse ovaries?
BACKGROUND Follicle stimulating hormone (FSH) exerts action on both germline and somatic compartment in both ovary and testis although FSH receptors (FSHR) are localized only on the somatic cells namely granulosa cells of growing follicles and Sertoli cells in the seminiferous tubules. High levels of FSH in females are associated with poor ovarian reserve, ovarian hyper stimulation syndrome etc...
متن کاملFollistatin288 Regulates Germ Cell Cyst Breakdown and Primordial Follicle Assembly in the Mouse Ovary
In mammals, the primordial follicle pool represents the entire reproductive potential of a female. The transforming growth factor-β (TGF-β) family member activin (ACT) contributes to folliculogenesis, although the exact mechanism is not known. The role of FST288, the strongest ACT-neutralizing isoform of follistatin (FST), during cyst breakdown and primordial follicle formation in the fetal mic...
