Mare’s Folliculogenesis: Assessment of ovarian and perifollicular vascular perfusion by Doppler ultrasound
Background: Ultrasound Doppler is a new technology that has recently been used in large animal reproduction. As the conventional ultrasound (B-mode) it is a noninvasive technique, but with the advantage of allows the assessment of the hemodynamic of reproductive tract in real time. The observation of important features of the vascularization and changes that occur during physiological processes...
متن کاملGap junctions and ovarian folliculogenesis.
Gap junctions are collections of intercellular membrane channels that allow adjacent cells to share small molecules (< 1 kDa). Gap junction channels are composed of connexins, a homologous family of more than 20 proteins. In developing follicles, gap junctions couple the growing oocyte and its surrounding follicle cells into a functional syncytium. This review summarizes evidence on the express...
متن کاملAn oocentric view of folliculogenesis and embryogenesis.
The mammalian oocyte undertakes a highly complex journey to maturity during which it successively acquires a series of characteristics necessary for fertilization and the development of a healthy embryo. While the contribution of granulosa cells to oocyte development has been studied for many years, it has recently become apparent that the oocyte itself plays a key role in directing its own fat...
متن کاملIntraovarian control of early folliculogenesis.
Although hormonal regulation of ovarian follicle development has been extensively investigated, most studies concentrate on the development of early antral follicles to the preovulatory stage, leading to the successful use of exogenous FSH for infertility treatment. Accumulating data indicate that preantral follicles are under stringent regulation by FSH and local intraovarian factors, thus pro...
متن کاملEpigenetic control of folliculogenesis and luteinization
Folliculogenesis and luteinization are characterized by irreversible and profound physiological and morphological transformation processes, which eventually culminate in the provision of fertilizable eggs and the conversion of the estrogen producing follicle into a progesterone producing corpus luteum. All these processes are preceded by complex alterations of the gene expression profiles in th...
