Folliculogenesis is an important part of ovarian function as it provides the oocytes for female reproductive life. Characterizing genes/proteins involved in folliculogenesis is fundamental for understanding the mechanisms associated with this biological function and to cure the diseases associated with folliculogenesis. A large number of genes/proteins associated with folliculogenesis have been...

The Vaccinia-related kinase 1(VRK1), which is generally implicated in modulating cell cycle, plays important roles in mammalian gametogenesis. Female infertility in VRK1-deficient mice was reported to be caused by defective meiotic progression in oocyte at postovulatory stage. VRK1 roles in folliculogenesis, however, remain largely unknown. Here, accurate quantification of folliculogenesis is p...

The ovarian follicle is the fundamental unit of the ovary. It contains the oocyte that may eventually ovulate, undergo fertilization and form an embryo. It also provides the steroid and protein hormones required for maintenance of the ovarian cycle, the secondary sex characteristics and preparation of the uterus for implantation. Follicle formation and folliculogenesis have been well documented...

BACKGROUND Recent findings have revealed that the female gonad may have regenerative activity with having germ line stem cells in juveniles and adults. Application of these germ line stem cells could be an alternative therapy for reproductive disorders in regenerative medicine. METHODS To enhance the potency of differentiation into oocyte-like cells (OLCs) and folliculogenesis, we overexpress...

Thyroid follicles, the functional units of the thyroid gland, are delineated by a monolayer of thyrocytes resting on a continuous basement membrane. The developmental mechanisms of folliculogenesis, whereby follicles are formed by the reorganization of a non-structured mass of non-polarized epithelial cells, are largely unknown. Here we show that assembly of the epithelial basement membrane is ...

background: induction of ovulation in art is necessary for superovulation and the side effects of superovulatory drugs are debated. oxytocin as a natural hormone, have receptors and is synthesized by several reproductive organs. preovulatory presence of oxytocin receptor mrnas in granulosa cells indicating a role for oxytocin in follicular development. objective: the aim of the present study wa...

In mammals, the role played by germ cells in ovarian differentiation and folliculogenesis has been the focus of an increasing number of studies over the last decades. From these studies, it has emerged that bidirectional communication between germ cells and surrounding companion cells is required as soon as the initial assembly of follicles. Models of germ cell depletion that arise from both sp...
