The government has certain rights to the invention. BACKGROUND OF THE INVENTION 15 [0003] Effects of luteolin and quercetin, inhibitors of tyrosine kinase, on cell growth and metastasis-associated prop- erties in A431 cells overexpressing epidermal growth factor receptor, are described in British Journal of Pharmacology 1999; 128: 999-1010. [0004] WO 2006/105540 A2 describes methods and means comprising nicotinamide riboside for modulating the sirtuin pathway.WO 01/30980 A2 relates to methods and compositions for enhancing developmental potential of oocytes and 20 zygotes. [0005] Igosheva et al., PLoS ONE 2010 5 (4): e10074 describe that maternal diet-induced obesity alters mitochondrial activity and redox status in mouse oocytes and zygotes. [0006] Since the early 1950s, clinical management of problems associated with ovarian insufficiency and failure, including infertility due to aging or insults, has been restricted by the belief that the pool of oocytes set forth at birth is 25 not amenable to replacement or renewal (Zuckerman, Recent Prog Horm Res 1951 6:63-108). In other words, any therapeutic intervention had to conform to manipulation of the existing stockpile of oocyte-containing follicles to produce a desired clinical outcome. In 2004, however, studies with mice challenged the idea of a fixed ovarian reserve of oocytes being endowed at birth (Johnson et al., Nature 2004 428:145-150). Based on results from several experimental ap- proaches, it was concluded that ovaries of adult female mammals retain rare germline or oogonial stem cells (OSCs) 30 that routinely produce new oocytes in a manner analogous to germline stem cell support of sperm production in the adult testis (Spradling, Nature 2004 428:133-134). Several years later, OSCs were successfully isolated from neonatal and adult mouse ovaries (Zou et al., Nat Cell Biol 2009 11:631-636; Pachiarotti et al., Differentiation 2010 79:159-170). Collectively, these investigations, along with several other reports from studies of mice (Johnson et al., Cell 2005 122:303-315; Wang et al., Cell Cycle 2010 9:339-349; Niikura et al., Aging 2010 2:999-1003) have conceptually validated 35 the use of OSCs as agents for transplantation and as targets for new therapies to modulate ovarian function and female fertility (Tilly et al., Biol Reprod 2009 80:2-12; Tilly et al., Mol Hum Reprod 2009; 15:393-398). In addition, the identificat ion of dormant OSCs in atrophic ovaries of aged mice, which spontaneously resume oocyte formation when exposed to a young adult ovarian environment, indicates that ovarian aging may be reversible (Niikura et al., Aging 2009 1:971-978; Massasa et al., Aging 2010; 2:1-2). The clinical utility of OSCs is now further confirmed by evidence shown herein that 40 a comparable population of oocyte-producing stem cells exists in, and can be purified from, ovaries of healthy repro- ductive-age women. [0007] Although these new studies indicate that oocyte numbers in adult ovaries are amenable to therapeutic expansion through OSC-based technology, ovarian aging and failure is determined by both a decline in oocyte number as well as a decline in the quality of the oocytes present in the ovaries. Hence, it is imperative to identify methods for improving 45 oocyte quality, especially in women of advancing maternal age. During the past few decades, because of cultural and social changes, women in the developed world have significantly delayed childbirth. For example, first birth rates for women 35-44 years of age in the United States have increased by more than 8-fold over the past 40 years (Ventura Vital Health Stat 2009 47:1-27; Matthews, NCHS Data Brief 2009 21:1-8). It is well known that pregnancy rates in women at 35 or more years of age are significantly lower, both naturally and with assisted reproduction. The decline in live birth 50 rate reflects a decline in response to ovarian stimulation by gonadotropin hormones (follicle-stimulating hormone or FSH, and luteinizing hormone or LH), reduced oocyte and embryo quality and pregnancy rates, and an increased incidence of miscarriages and fetal aneuploidy. In fact, aging-associated chromosomal and meiotic spindle abnormalities in eggs are considered the major factors responsible for the increased incidence of infertility, fetal loss (miscarriage) and con- ceptions resulting in birth defects - most notably trisomy 21 or Down syndrome - in women at advanced reproductive 55 ages (Henderson et al., Nature 1968 218:22-28; Hassold et al., Hum Genet 1985 70:11-17; Battaglia et al., Hum Reprod 1996 11:2217-2222; Hunt et al., Trends Genet 2008 24:86-93). Although the occurrence and consequences of aging- related aneuploidy in oocytes of humans and animal models have been extensively studied (Tarín et al., Biol Reprod 2001 65:141-150; Pan et al., Dev Biol 2008 316:397-407; Duncan et al., Biol Reprod 2009 81:768-776), approaches to 3 EP 2 726 601 B1 maintain fidelity of chromosome segregation during meiotic cell division with age have remained elusive. At present there is no known intervention to improve the pregnancy outcome of older female patients. In animal studies, chronic administration of pharmacologic doses of anti-oxidants during the juvenile period and throughout adult reproductive life has been reported to improve oocyte quality in aging female mice (Tarín et al., Mol Reprod Dev 2002 61:385-397). 5 However, this approach has significant long-term negative effects on ovarian and uterine function, leading to higher fetal death and resorptions as well as decreased litter frequency and size in treated animals (Tarín et al., Theriogenology 2002 57:1539-1550). Thus, clinical translation of chronic anti-oxidant therapy throughout reproductive life for maintaining or improving oocyte quality in aging females is impractical.

This rare cell population has now been reported in the mouse, rat, pig, rhesus macaque monkey and humans and, although a physiological role for the cells has not been proven, they do appear to generate oocytes when cultured in specific environments, resulting in live offspring in rodents.

Each follicle contains one oocyte enclosed in somatic cells and follicle number is determined during fetal development in humans. Growth and development of ovarian follicles (folliculogenesis) is necessary to produce viable gametes as well as ovarian hormones including estrogen and progesterone. Folliculogenesis begins in the fetal ovary and may span several decades of life. Environmental and nutritional factors that affect folliculogenesis have the potential to impact health and fertility, and may be a source of new biotechnological innovation. One such factor, zinc, has previously been found to impact the final stages of follicle development including meiotic division, ovulation, epigenetic modification, fertilization, and embryo development. However, the role of zinc during the early stages of folliculogenesis have not been evaluated.

  • FACS-Sorted Putative Oogonial Stem Cells from the Ovary Are Neither
    www.nature.com/scientificreports OPEN FACS-sorted putative oogonial stem cells from the ovary are neither DDX4-positive nor germ Received: 30 March 2016 Accepted: 26 May 2016 cells Published: 15 June 2016 Larissa Zarate-Garcia, Simon I. R. Lane, Julie A. Merriman & Keith T. Jones Whether the adult mammalian ovary contains oogonial stem cells (OSCs) is controversial. They have been isolated by a live-cell sorting method using the germ cell marker DDX4, which has previously been assumed to be cytoplasmic, not surface-bound. Furthermore their stem cell and germ cell characteristics remain disputed. Here we show that although OSC-like cells can be isolated from the ovary using an antibody to DDX4, there is no good in silico modelling to support the existence of a surface-bound DDX4. Furthermore these cells when isolated were not expressing DDX4, and did not initially possess germline identity. Despite these unremarkable beginnings, they acquired some pre- meiotic markers in culture, including DDX4, but critically never expressed oocyte-specific markers, and furthermore were not immortal but died after a few months. Our results suggest that freshly isolated OSCs are not germ stem cells, and are not being isolated by their DDX4 expression. However it may be that culture induces some pre-meiotic markers. In summary the present study offers weight to the dogma that the adult ovary is populated by a fixed number of oocytes and that adultde novo production is a rare or insignificant event. The prevailing dogma in the field of reproductive biology for over 60 years has been that the adult mammalian ovary lacks germ stem cells1.

  • Genetic Studies in Mice Directly Link Oocytes Produced During Adulthood
    www.nature.com/scientificreports OPEN Genetic studies in mice directly link oocytes produced during adulthood to ovarian function and natural Received: 23 June 2017 Accepted: 1 August 2017 fertility Published: xx xx xxxx Ning Wang1,2, Chonthicha Satirapod1,2, Yasuyo Ohguchi1,2, Eun-Sil Park3,4, Dori C. Woods3 & Jonathan L. Tilly3 Multiple labs have reported that mammalian ovaries contain oogonial stem cells (OSCs), which can diferentiate into oocytes that fertilize to produce ofspring. However, the physiological relevance of these observations to adult ovarian function is unknown. Here we performed targeted and reversible ablation of premeiotic germ cells undergoing diferentiation into oocytes in transgenic mice expressing the suicide gene, herpes simplex virus thymidine kinase (HSVtk), driven by the promoter of stimulated by retinoic acid gene 8 (Stra8), a germ cell-specifc gene activated during meiotic commitment. Over a 21-day ablation phase induced by the HSVtk pro-drug, ganciclovir (GCV), oocyte numbers declined due to a disruption of new oocyte input. However, germ cell diferentiation resumed after ceasing the ablation protocol, enabling complete regeneration of the oocyte pool. We next employed inducible lineage tracing to fate map, through Cre recombinase-mediated fuorescent reporter gene activation only in Stra8-expressing cells, newly-formed oocytes. Induction of the system during adulthood yielded a mosaic pool of unmarked (pre-existing) and marked (newly-formed) oocytes. Marked oocytes matured and fertilized to produce ofspring, which grew normally to adulthood and transmitted the reporter to second-generation ofspring. These fndings establish that oocytes generated during adulthood contribute directly to ovarian function and natural fertility in mammals.

Males have the ability to maintain a constant pool of spermatozoa via mitotic division of germ-line stem cells known as type A dark spermatogonia. These type A dark spermatogonia in adult male avian species continually go through mitosis to keep up with the lifelong demand of spermatogenesis. The presence of spermatogonial stem cells within adult male testes could make it possible to isolate the stem-cells from the gonads of deceased male birds followed by xenotransfer to domestic host embryos. Depending on the environmental conditions, it is possible to isolate and use germline stem cells within hours to days following a bird’s death.

  • Reproductionreview
    REPRODUCTIONREVIEW Oocyte stem cells: fact or fantasy? Corrina J Horan and Suzannah A Williams Nuffield Department of Obstetrics and Gynaecology, University of Oxford, Women’s Centre, John Radcliffe Hospital, Oxford, United Kingdom Correspondence should be addressed to S A Williams; Email: [email protected] Abstract For many decades, the dogma prevailed that female mammals had a finite pool of oocytes at birth and this was gradually exhausted during a lifetime of reproductive function. However, in 2004, a new era began in the field of female oogenesis. A study was published that appeared to detect oocyte-stem cells capable of generating new eggs within mouse ovaries. This study was highly controversial and the years since this initial finding have produced extensive research and even more extensive debate into their possibility. Unequivocal evidence testifying to the existence of oocyte-stem cells (OSCs) has yet to be produced, meanwhile the spectrum of views from both sides of the debate are wide-ranging and surprisingly passionate. Although recent studies have presented some convincing results that germ cells exist and are capable of creating new oocytes, many questions remain. Are these cells present in humans? Do they exist in physiological conditions in a dormant state? This comprehensive review first examines where and how the dogma of a finite pool was established, how this has been challenged over the years and addresses the most pertinent questions as to the current status of their existence, their role in female fertility, and perhaps most importantly, if they do exist, how can we harness these cells to improve a woman’s oocyte reserve and treat conditions such as premature ovarian insufficiency (POI: also known as premature ovarian failure, POF).

However, accumulating evidence demonstrated that, besides the animal models including primarily mice, even in adult women putative OSCs obtained from ovarian cortex are capable to differentiate in vitro into oocyte-like cells (OLCs) expressing molecular markers typical of terminal stage of oogonial cell lineage. Recent studies describe that, similarly to mature oocytes, the OSC-derived OLCs also contain haploid karyotype. As proof of concept of their stem commitment, OSCs from mice differentiated to oocytes in vitro are suitable to be fertilized and implanted in sterilized animals resulting in embryo development.
