(Submitter supplied) Primordial follicles are the first class of follicles formed in the mammalian ovary and are comprised of an oocyte surrounded by a layer of squamous pre-granulosa cells. This developmental class remains in a non-growing state until individual follicles activate to initiate folliculogenesis. What regulates the timing of follicle activation and the upstream signals that govern these processes are major unanswered questions in ovarian biology. more...

(Submitter supplied) The dormant population of ovarian primordial follicles is determined at birth and serves as the reservoir for future female fertility. Of equal importance to fertility is the rate that primordial follicles activate and enter folliculogenesis, yet our understanding of the molecular, biochemical, and cellular processes underpinning primordial follicle activation remains limited. The survival of primordial follicles relies on the correct complement and morphology of granulosa cells, which provide signalling factors essential for oocyte and follicular survival. more...

(Submitter supplied) Female fertility is determined in part by the size and development of the primordial follicle pool. The current study investigates the role of glial cell-line derived neurotrophic factor (GDNF) in the regulation of primordial follicle development in the ovary. Ovaries from four-day old female rat pups were maintained in organ culture for ten days in the absence (control) or presence of GDNF or kit ligand/stem cell factor (KL). more...

(Submitter supplied) The ovarian tissues at E16.5, postnatal 0 day (PD0 ) and 3 days (PD3) in mice were collected to perform single-cell RNA sequence (scRNA-seq) in this study. The transcriptome landscape of different cell types contributed to discern the intrinsic mechanism of early folliculogenesis, and the developmental stage-specific germline and somatic cells were defined to reveal their genetic programs along with follicle development as well as their regulative molecules and interaction signals. more...

(Submitter supplied) The dynamic transcriptional regulation and interactions of human germlines and surrounding somatic cells during folliculogenesis remains unknown. Using RNA-Seq analysis of human oocytes and corresponding granulosa cells (GCs) spanning five follicular stages, we revealed unique features in transcriptional machinery, transcription factor networks and reciprocal interactions in human oocytes and GCs that displayed developmental-stage-specific expression patterns. more...

(Submitter supplied) The oocytes found within the primordial follicles of mammalian ovaries remain quiescent for months to years until they receive the appropriate signals to undergo the primordial to primary follicle transition and initiate folliculogenesis. The molecular mechanisms and extracellular signaling factors that regulate this process remain to be fully elucidated. The current study investigates the mechanisms utilized by anti-Müllerian hormone (AMH; i.e. more...

(Submitter supplied) The Pik3cd null females are subfertile and have less growing follicles than their heterozygous littermates in the ovary. These mice poorly respond to the exogenous gonadotropins and ovulate much less oocytes than controls. In addition, the estrodial stimulated GC proliferation in preantral follicles is also impaired in Pik3cd null ovaries. FSH and E2 dramatically activates PI3K/AKT pathway in GCs of wild type mice, but not in the Pik3cd null mice. more...

(Submitter supplied) The assembly of the developmentally arrested primordial follicle and subsequent transition to the primary follicle are poorly understood processes critical to ovarian biology. Abnormal primordial follicle development can lead to pathologies such as premature ovarian failure. The current study used a genome-wide expression profile to investigate primordial follicle assembly and development. Rat ovaries with predominantly unassembled, primordial, or primary follicles were obtained. more...

(Submitter supplied) In mammalian females, quiescent primordial follicles serve as the ovarian reserve and sustain normal ovarian function and egg production via folliculogenesis. The loss of primordial follicles causes ovarian aging. Cellular senescence, characterized by cell cycle arrest and production of the senescence-associated secretory phenotype (SASP), is associated with tissue aging. In the present study, we report that some quiescent primary oocytes in primordial follicles become senescent in adult mouse ovaries. more...

(Submitter supplied) The ovarian reserve of follicles comprises all oocytes for lifetime fertility and is depleted by progressive activation. The orphan nuclear receptor liver receptor homolog 1 (LRH-1; Nr5a2) is essential for ovulation, but its role in the early stages of follicular development is not known. We therefore developed a model of conditional depletion of LRH-1 from early postnatal ovaries (postnatal day 4) and performed RNAsequencing to identify LRH-1 regulated genes during the earliest stages of follicular activation.

(Submitter supplied) Estradiol-17β (E2) has been shown to promote primordial follicle (PF) formation and to involve BMP2 as a downstream effector to promote PF in the hamsters. However, the molecular mechanism whereby these factors regulate ovarian somatic cells to pre-granulosa cells (preGC) transition leading to PF formation remains unclear. The objective of this study was to determine whether BMP2 and/or E2 would regulate the expression of specific ovarian transcriptome during preGC transition and PF formation in the mouse ovary. more...

(Submitter supplied) The ovarian reserve of follicles comprises all oocytes for lifetime fertility and once formed, it is non renewing. The orphan nuclear receptor steroidogenic factor 1 (SF-1; Nr5a1) is essential for steroidogenesis, but its role in the earliest stages of follicular development is not known. We therefore developed a model of conditional depletion of SF-1 from prenatal ovaries and performed RNAsequencing to identify SF-1 regulated genes.

(Submitter supplied) In mammals, meiotically competent oocytes develop cyclically during ovarian folliculogenesis. During their development, prophase I arrested oocytes are highly  transcriptionally active in preparation for the resumption of meiosis  and early stages of embryogenesis prior to the maternal to zygotic transition. Defective oocyte development during folliculogenesis leads to meiotic defects, aneuploidy, follicular atresia, or non-viable embryos. more...

(Submitter supplied) Mammalian follicle development is characterised by extensive changes in morphology, endocrine responsiveness, and function, providing the optimum environment for oocyte growth, development, and resumption of meiosis. In cattle, the first signs of transcription activation in the oocyte are observed in the secondary follicle, later than during mouse and human oogenesis. While many studies have generated extensive datasets characterising gene expression in bovine oocytes, they are mostly limited to the analysis of fully grown and matured oocytes. more...

(Submitter supplied) Reconstituted Ovaries (rOvaries) represent an important method for in vitro derivation of gametes. The beginning of this process requires differentiation of mouse induced pluripotent stem cells (iPSCs) into Epiblast Like Cells (EpiLCs) followed by 6 days of differentiation as spheres containing PGC-Like Cells (PGCLCs) and somatic cells. Here, we characterize the cells in the differentiated spheres at day 6 of differentiation.

(Submitter supplied) A major technology for generating oocytes by in vitro gametogenesis involves generating ovary models called reconstituted ovaries (rOvaries). Widespread use of rOvaries depends on the reliable manufacturing of primordial germ cell like cells (PGCLCs) and fetal ovarian somatic cells (FOSCs). Using scRNA-seq, we identify that upon thaw, FOSCs are composed largely of Foxl2+ pre-granulosa cells, KRT19+ epithelial cells and Nr2f2+ mesenchymal cells which self-assemble together with PGCLCs into disc-like organoids containing multiple follicles embedded in NR2F2 stroma without an ovarian surface epithelium and no steroidogenic theca. more...

(Submitter supplied) Spatially resolved, single-cell transcriptome analysis of high quality remains challenging, despite the rise of high-resolution spatial transcriptomics. Laser-capture microdissection (LCM) is widely used to isolate cells of interest from tissue sections. Here, we developed DRaqL (Direct RNA recovery and quenching for LCM), a technique that allows efficient lysis of single, LCM-isolated cells from alcohol- and formalin-fixed tissue and stained frozen sections, and that is amenable to enzymatic reactions for cDNA amplification within the same sampling tubes. more...
