Regulation 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 کاملAngiogenic factors and ovarian follicle development
Ovarian follicles require an adequate blood supply for oxygen, nutrients and hormones, in addition to eliminating CO2 and other metabolites. Acquisition of an adequate vascular supply is probably a limiting step in the selection and maturation of the dominant follicle. In this way, there is a progressive interest in the study of the growth factors involved in the angiogenic process. In addition...
متن کاملWnt Signaling in Hair Follicle Development
HF is a mini-organ formed with mesenchymal-epithelial interaction (Schmidt-Ullrich & Paus, 2005). HF development and cycle are depended on signaling between its epidermal and dermal components. Especially, dermal organizing center, DP, is both chemical and physical niche for epithelial stem cells. DP plays an important role in HF induction and cycling by controlling self-renewal and differentia...
متن کاملPostnatal ovarian follicle development in hypogonadal (hpg)
Significant uterine growth occurred in normal and hypogonadal (hpg) mice between Days 7 and 21 but thereafter no further growth was observed in hpg mice. The ovaries of hpg mice were significantly smaller than those of normals at all ages, but there was no significant difference between the number of non-growing follicles in the ovaries of mutants and their normal littermates at any age studied...
متن کاملEchographic Evidence of Follicle Development and Maturation
Monitoring of individual follicles during the menstrual cycle demonstrates in a non-invasive way the changes in their number and position during the early and the late follicular phase and the luteal phase. The differences in relations between the follicles near the dominant follicle can be demonstrated with the same technique using 3D reconstruction of the ovary. Recognition of the follicle gr...
