Investigating the impact of vitrification on bovine ovarian tissue morphology, follicle survival, and transcriptomic signature. J Assist Reprod Genet 2024; 41:1035-1055. [PMID: 38358432 PMCID: PMC11052753 DOI: 10.1007/s10815-024-03038-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 01/18/2024] [Indexed: 02/16/2024] Open
Abstract
PURPOSE Ovarian tissue cryopreservation is vital for fertility preservation, yet its effect on ovarian tissue follicle survival and transcriptomic signature requires further investigation. This study delves into the effects of vitrification on tissue morphology, function, and transcriptomic changes, helping to find possibilities for vitrification protocol improvements. METHODS Ovarian cortex from 19 bovine animals were used to conduct pre- and post-vitrification culture followed by histological assessment, immunohistochemistry, and TUNEL assay. Follicles' functionality was assessed for viability and growth within the tissue and in isolated cultures. RNA-sequencing of ovarian tissue was used to explore the transcriptomic alterations caused by vitrification. RESULTS Follicle density, cell proliferation, and DNA damage in ovarian stroma were unaffected by vitrification. However, vitrified cultured tissue exhibited reduced follicle density of primordial/primary and antral follicles, while freshly cultured tissue manifested reduction of antral follicles. Increased stromal cell proliferation and DNA damage occurred in both groups post-culture. Isolated follicles from vitrified tissue exhibited similar viability to fresh follicles until day 4, after which the survival dropped. RNA-sequencing revealed minor effects of vitrification on transcriptomic signatures, while culture induced significant gene expression changes in both groups. The altered expression of WNT and hormonal regulation pathway genes post-vitrification suggests the molecular targets for vitrification protocol refinement. CONCLUSION Vitrification minimally affects tissue morphology, follicle density, and transcriptomic signature post-thawing. However, culture revealed notable changes in vitrified tissue samples, including reduced follicle density, decreased isolated follicle survival, and alteration in WNT signalling and ovarian hormonal regulation pathways, highlighted them as possible limitations of the current vitrification protocol.

Reprod Biol 2024; 24:100851.

Abstract
Ovarian follicle culture is a powerful tool to study follicular physiology and has potential applications in clinical and commercial settings. Despite remarkable progress, recreating folliculogenesis in vitro remains challenging for many mammalian species. This study investigates the impact of platelet-rich plasma (PRP) derived from adult blood (human platelet lysate, hPL) and umbilical cord blood (Umbilical cord plasma, UCP) on murine pre-antral follicle culture and oocyte maturation. Pre-antral follicles were cultured individually for 10 days with fetal bovine serum (FBS) serving as the control and two PRP sources (hPL and UCP) and their activated forms (Ac-hPL and Ac-UCP). The results suggest that neither hPL nor UCP, regardless of activation status, improved follicle culture outcomes compared to FBS. Interestingly, activation did not significantly impact the main functional outcomes such as maturation rates, survival, and growth. Oestradiol secretion and oocyte diameter, often considered hallmarks of follicle quality, did not show significant differences between matured and non-matured oocytes across the treatment groups. However, gene expression analysis revealed a significant upregulation of Gdf-9 and Bmp-15 mRNA levels in oocytes from the Ac-UCP group, regardless of maturation stage, suggesting that the accumulation of the mRNA could be due to potential challenges in translation in the Ac-UCP group. In conclusion, this study challenges the hypothesis that PRP, as a serum source, could improve follicle culture outcomes compared to FBS, the gold standard in murine follicle culture. Further research is needed to understand the species-specific effects of PRP and explore other potential factors affecting follicle culture and oocyte quality.

Abstract
In the space of 50 years, we have seen incredible achievements in human reproductive medicine. With these leaps forward, it is no wonder that there is a major interest in women's reproductive health research, including extension of reproductive lifespan. Substantial effort is currently being made to address this challenge, including from the commercial sector. In vitro gametogenesis (IVG) in mice is a spectacular breakthrough and has the potential to offer hope to women with intractable infertility. However, with such lofty goals, some reflection may be called for: mastering all of the techniques required for complete and safe IVG in women is likely to be extraordinarily difficult.

Abstract
Today, fertility preservation is receiving more attention than ever. Cryopreservation, which preserves ovarian tissue to preserve fertility in young women and reduce the risk of infertility, is currently the most widely practiced. Transplantation, however, is less feasible for women with blood-borne leukemia or cancers with a high risk of ovarian metastasis because of the risk of cancer recurrence. In addition to cryopreservation and re-implantation of embryos, in vitro ovarian organ reconstruction techniques have been considered as an alternative strategy for fertility preservation. In vitro culture of oocytes in vitro Culture, female germ cells induction from pluripotent stem cells (PSC) in vitro, artificial ovary construction, and ovaria-related organoids construction have provided new solutions for fertility preservation, which will therefore maximize the potential for all patients undergoing fertility preservation. In this review, we discussed and thought about the latest ovarian organ function reconstruction techniques in vitro to provide new ideas for future ovarian disease research and fertility preservation of patients with cancer and premature ovarian failure.

Abstract
In vitro maturation (IVM) is not a routine assisted reproductive technology (ART) for oocytes collected from early antral (EA) follicles, a large source of potentially available gametes. Despite substantial improvements in IVM in the past decade, the outcomes remain low for EA-derived oocytes due to their reduced developmental competences. To optimize IVM for ovine EA-derived oocytes, a three-dimensional (3D) scaffold-mediated follicle-enclosed oocytes (FEO) system was compared with a validated cumulus-oocyte complex (COC) protocol. Gonadotropin stimulation (eCG and/or hCG) and/or somatic cell coculture (ovarian vs. extraovarian-cell source) were supplied to both systems. The maturation rate and parthenogenetic activation were significantly improved by combining hCG stimulation with ovarian surface epithelium (OSE) cells coculture exclusively on the FEO system. Based on the data, the paracrine factors released specifically from OSE enhanced the hCG-triggering of oocyte maturation mechanisms by acting through the mural compartment (positive effect on FEO and not on COC) by stimulating the EGFR signaling. Overall, the FEO system performed on a developed reproductive scaffold proved feasible and reliable in promoting a synergic cytoplasmatic and nuclear maturation, offering a novel cultural strategy to widen the availability of mature gametes for ART.

Abstract
Oogenesis and folliculogenesis are considered as complex and species-specific cellular differentiation processes, which depend on the in vivo ovarian follicular environment and endocrine cues. Considerable efforts have been devoted to driving the differentiation of female primordial germ cells toward mature oocytes outside of the body. The recent experimental attempts have laid stress on offering a suitable microenvironment to assist the in vitro folliculogenesis and oogenesis. Despite developing a variety of bioengineering techniques and generating functional mature gametes through in vitro oogenesis in earlier studies, we still lack knowledge of appropriate microenvironment conditions for building biomimetic culture systems for female fertility preservation. Therefore, this review paper can provide a source for a large body of scientists developing cutting-edge in vitro culture systems for female germ cells or setting up the next generation of reproductive medicine as feasible options for female infertility treatment. The focal point of this review outlines advanced bioengineering technologies such as 3D biofabricated hydrogels/scaffolds and microfluidic systems utilized with female germlines for fertility preservation through in vitro folliculogenesis and oogenesis.

Abstract
Millions of people around the world suffer from infertility, with the number of infertile couples and individuals increasing every year. Assisted reproductive technologies (ART) have been widely developed in recent years; however, some patients are unable to benefit from these technologies due to their lack of functional germ cells. Therefore, the development of alternative methods seems necessary. One of these methods is to create artificial oocytes. Oocytes can be generated in vitro from the ovary, fetal gonad, germline stem cells (GSCs), ovarian stem cells, or pluripotent stem cells (PSCs). This approach has raised new hopes in both basic research and medical applications. In this article, we looked at the principle of oocyte development, the landmark studies that enhanced our understanding of the cellular and molecular mechanisms that govern oogenesis in vivo, as well as the mechanisms underlying in vitro generation of functional oocytes from different sources of mouse and human stem cells. In addition, we introduced next-generation ART using somatic cells with artificial oocytes. Finally, we provided an overview of the reproductive application of in vitro oogenesis and its use in human fertility.

Abstract
In vitro follicle development (IVFD) is an adequate model to obtain basic knowledge of folliculogenesis and provides a tool for ovarian toxicity screening. IVFD yielding competent oocytes may also offer an option for fertility and species preservation. To promote follicle growth and oocyte maturation in vitro, various culture systems are utilized for IVFD in rodents, domestic animals, wild animals, nonhuman primates, and humans. Follicle culture conditions have been improved by optimizing gonadotropin levels, regulatory factors, nutrient supplements, oxygen concentration, and culture matrices. This review summarizes quality assessment of oocytes generated from in vitro-developed antral follicles from the preantral stage, including oocyte epigenetic and genetic profile, cytoplasmic and nuclear maturation, preimplantation embryonic development following in vitro fertilization, as well as pregnancy and live offspring after embryo transfer. The limitations of oocyte quality evaluation following IVFD and the gaps in our knowledge of IVFD to support proper oocyte development are also discussed. The information may advance our understanding of the requirements for IVFD, with a goal of producing competent oocytes with genetic integrity to sustain embryonic development resulting in healthy offspring.

Abstract
To produce viable eggs from single primary follicles in vitro, primary follicles containing oocytes (average 39.0 ± 0.2 µm in diameter) were isolated from the ovaries of
1-week-old mice, and cultured in combination with culture membranes for the first 8 days up to the secondary follicle stage, followed by the next 12 days to the later stages. After culture
with a combination of first and second culture membranes using high and low adhesion characteristics, the average oocyte diameters of the surviving follicles increased by almost two-fold in
all four groups. Further, the oocyte maturation rate was the highest (74.1%) in the culture group with low adhesion with collagenase and high adhesion. In this culture group, when the
O2 concentration was changed from 20% in the first culture to 5% in the second culture, the cleavage rate increased to 47.5%, which was comparable to the level of the in
vivo control (34.6%). Finally, 39 embryos at the 2- to 8-cell stages were transferred into the oviducts of three pseudopregnant females, and eight live pups (20.5%) were obtained.
Of the eight pups, six survived for at least six months and were fertile. The present study shows successive in vitro cultures of single isolated primary follicles for the
production of viable eggs. We believe that this culture system, with a combination of culture membranes under controlled O2 conditions, is applicable to other mammalian species,
including humans.

Abstract
Mammalian ovaries contain a large number of immature follicles. Follicular culture can contribute to the production of fertile oocytes from latent immature follicles, providing a useful
tool for exploring the developmental competencies and related factors that oocytes acquire during growth. However, the potential of oocytes produced by follicular culture is limited. Herein,
the optimal follicular culture conditions for the addition of polyvinylpyrrolidone to the medium and oxygen concentration were investigated. Polyvinylpyrrolidone with a high molecular weight
(≥ 360,000) and a 7% oxygen concentration were found to increase the blastocyst formation rate by more than 20% compared with conventional culture conditions. Although the developmental
ability of oocytes produced by follicular culture remained inferior to that of in vivo-derived oocytes, these findings may pave the way for enhanced production of fertile
oocytes in vitro and for studying the process of full developmental potency acquisition by oocytes.

Abstract
Women with cancer and low ovarian reserves face serious challenges in infertility treatment. Ovarian tissue cryopreservation is currently used for such patients to preserve fertility. One major challenge is the activation of dormant ovarian follicles, which is hampered by our limited biological understanding of molecular determinants that activate dormant follicles and help maintain healthy follicles during growth. Here, we investigated the transcriptomes of oocytes isolated from dormant (primordial) and activated (primary) follicles under in vivo and in vitro conditions. We compared the biological relevance of the initial molecular markers of mature metaphase II (MII) oocytes developed in vivo or in vitro. The expression levels of genes involved in the cell cycle, signal transduction, and Wnt signaling were highly enriched in oocytes from primary follicles and MII oocytes. Interestingly, we detected strong downregulation of the expression of genes involved in mitochondrial and reactive oxygen species (ROS) production in oocytes from primordial follicles, in contrast to oocytes from primary follicles and MII oocytes. Our results showed a dynamic pattern in mitochondrial and ROS production-related genes, emphasizing their important role(s) in primordial follicle activation and oocyte maturation. The transcriptome of MII oocytes showed a major divergence from that of oocytes of primordial and primary follicles.

Abstract
To enhance the developmental competency of murine ovarian follicles cultured in vitro, C-type natriuretic peptide (CNP) was supplemented in the culture system. Although the mechanism is not fully elucidated, it was reported that the effect of CNP supplementation was mediated by increased cyclic guanosine monophosphate (cGMP). In the present study, cGMP levels in media for murine preantral follicle culture were compared both between a control group without CNP supplementation and an experimental group with CNP supplementation and between days in each group. In addition, follicle growth patterns and oocyte maturity were assessed and compared between the two groups. Results demonstrated that along with in vitro culture, cGMP levels increased (P < 0.05) both in the control group and the experimental group, whereas cGMP levels were not significantly different between the two groups on the same day of in vitro culture (P > 0.05). The oocyte's maturity was superior in the experimental group compared with the control group (P < 0.05). As ovarian follicles grew three-dimensionally in the experimental group but were flattened in the control group, CNP might improve oocyte maturity through maintaining the three-dimensional architecture of the ovarian follicle because of increased transzonal projections (TZP) and functional gap junctions between oocyte and surrounding granulosa cells.

Abstract
The present study investigated the effects of c-type natriuretic peptide (CNP) on the development of murine preantral follicles during in vitro growth (IVG). Preantral follicles isolated from ovaries of Kunming mice were cultured in vitro. In the culture system, CNP was supplemented in the experimental groups and omitted in the control groups. In Experiment 1, CNP was only supplemented at the early stage and follicle development was evaluated. In Experiments 2 and 3, CNP was supplemented during the whole period of in vitro culture. In Experiment 2, follicle development and oocyte maturity were evaluated. In Experiment 3, follicle development and embryo cleavage after in vitro fertilization (IVF) were assessed. The results showed that in the control groups in all three experiments, granulosa cells migrated from within the follicle and the follicles could not reach the antral stage. In the experimental groups in all three experiments, no migration of granulosa cells was observed and follicle development was assessed as attaining the antral stage, which was significantly superior to that of the control group (P < 0.0001). Oocyte meiotic arrest was effectively maintained, hence giving good developmental competence. In conclusion, CNP supplementation in the culture system during IVG benefited the development of murine preantral follicles.

Initial steps in reconstruction of the human ovary: survival of pre-antral stage follicles in a decellularized human ovarian scaffold. Hum Reprod 2020; 34:1523-1535. [PMID: 31286144 DOI: 10.1093/humrep/dez077] [Citation(s) in RCA: 74] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Revised: 04/04/2019] [Accepted: 04/25/2019] [Indexed: 11/13/2022] Open
Abstract
STUDY QUESTION Can a reconstructed ovary using decellularized human ovarian tissue (DCT) support survival of pre-antral stage follicles? SUMMARY ANSWER We have demonstrated an effective protocol for decellularization of human ovarian tissues and successful recellularization with isolated human ovarian cells and pre-antral follicles. WHAT IS KNOWN ALREADY Survivors of leukemia or ovarian cancer run a risk of reintroducing malignancy when cryopreserved ovarian tissue is transplanted to restore fertility. A reconstructed ovary free of malignant cells could provide a safe alternative. Decellularization of ovarian tissue removes all cells from the extracellular matrix (ECM) including possible malignancies and leaves behind a physiological scaffold. The ECM offers the complex milieu that facilitates the necessary interaction between ovarian follicles and their surroundings to ensure their growth and development. Previous studies have shown that decellularized bovine ovarian scaffolds supported murine follicle growth and restoration of ovarian function in ovariectomized mice. STUDY DESIGN, SIZE, DURATION Optimizing a decellularization protocol for human ovarian tissues and testing biofunctionality of the decellularized scaffolds in vitro and in vivo by reseeding with both murine and human pre-antral follicles and ovarian cells. PARTICIPANTS/MATERIALS, SETTING, METHODS Donated human ovarian tissue and isolated pre-antral follicles were obtained from women undergoing ovarian tissue cryopreservation for fertility preservation. Ovarian cortical and medullary tissues were decellularized using 0.1% sodium dodecyl sulfate (SDS) for 3, 6, 18 and 24 hours followed by 24 hours of 1 mg/mL DNase treatment and washing. Decellularization of ovarian tissues and preservation of ECM were characterized by morphological evaluation using Periodic Acid-Schiff (PAS) staining, DNA quantification, histochemical quantification of collagen content and immunofluorescence analysis for collagen IA, laminin, fibronectin and DNA. Human ovarian stromal cells and isolated human pre-antral follicles were reseeded on the DCT and cultured in vitro. Isolated murine (N = 241) and human (N = 20) pre-antral follicles were reseeded on decellularized scaffolds and grafted subcutaneously to immunodeficient mice for 3 weeks. MAIN RESULTS AND THE ROLE OF CHANCE Incubation in 0.1% SDS for 18-24 hours adequately decellularized both human ovarian medullary and cortical tissue by eliminating all cells and leaving the ECM intact. DNA content in DCT was decreased by >90% compared to native tissue samples. Histological examination using PAS staining confirmed that the cortical and medullary tissues were completely decellularized, and no visible nuclear material was found within the decellularized sections. DCT also stained positive for collagen I and collagen quantities in DCT constituted 88-98% of the individual baselines for native samples. Human ovarian stroma cells were able to recellularize the DCT and isolated human pre-antral follicles remained viable in co-culture. Xenotransplantation of DCT reseeded with human or murine pre-antral follicles showed, that the DCT was able to support survival of human follicles and growth of murine follicles, of which 39% grew to antral stages. The follicular recovery rates after three weeks grafting were low but similar for both human (25%) and murine follicles (21%). LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Further studies are needed to increase recovery and survival of the reseeded follicles. Longer grafting periods should be evaluated to determine the developmental potential of human follicles. Survival of the follicles might be impaired by the lack of stroma cells. WIDER IMPLICATIONS OF THE FINDINGS This is the first time that isolated human follicles have survived in a decellularized human scaffold. Therefore, this proof-of-concept could be a potential new strategy to eliminate the risk of malignant cell re-occurrence in former cancer patients having cryopreserved ovarian tissue transplanted for fertility restoration. STUDY FUNDING/COMPETING INTEREST(S) This study is part of the ReproUnion collaborative study, co-financed by the European Union, Interreg V ÖKS. Furthermore, Project ITN REP-BIOTECH 675526 funded by the European Union, European Joint Doctorate in Biology and Technology of the Reproductive Health, the Research Pools of Rigshospitalet, the Danish Cancer Foundation and Dagmar Marshalls Foundation are thanked for having funded this study.

Abstract
In addition to the great growing need for assisted reproduction technologies (ART), additional solutions for patients without functional gametes are strongly needed. Due to ethical restrictions, limited studies can be performed on human gametes and embryos; however, artificial gametes and embryos represent a new hope for clinical application and basic research in the field of reproductive medicine. Here, we provide a review of the research progress and possible application of artificial gametes and embryos from different species, including mice, monkeys and humans. Gametes specification from adult stem cells and embryonic stem cells (ESCs) as well as propagation of stem cells from the reproductive system and from organized embryos, which are similar to blastocysts, have been realized in some nonhuman mammals, but not all achievements can be replicated in humans. This area of research remains noteworthy and requires further study and effort to achieve the reconstitution of the entire cycle of gametogenesis and embryo development in vitro.

Abstract
Eggs are female germ cells that are required for producing offspring through sexual reproduction. In mammals, eggs are produced in the ovary and ovulated into the oviduct. It is well known that over 99% of eggs are degenerated without ovulation, so that many studies have attempted in vitro folliculogenesis to produce many eggs in different species for a few decades. Although many methods have been developed, a success of in vitro egg production with the resultant live birth of offspring has been limited, especially in livestock animals. More recently, we have succeeded in producing live pups derived from in vitro/ex vivo egg production in mice. This review aims to introduce our recent findings with a brief history of in vitro/ex vivo culture systems for follicles and ovaries.

Abstract
Women affected by ovarian pathologies or with cancer can usually preserve fertility by egg/embryo freezing. When oocyte retrieval is not feasible, the only option available is ovarian tissue cryopreservation and transplantation. The culture of follicles isolated from fresh or cryopreserved ovaries is considered still experimental, although this procedure is considered safer, because the risk of unintentional spreading of cancer cells eventually present in cryopreserved tissue is avoided. Animal and human small follicles can be cultured in vitro, but standardized protocols able to produce in vitro grown oocytes with the same developmental capacity of in vivo grown oocytes are not available yet. In fact, the different sizes of follicles and oocytes, the hormonal differences existing between mono- (e.g., human, goat, cow, and sheep) and poly-ovulatory (rodents and pig) species, and the incomplete identification of the mechanisms regulating the oocyte–follicle and follicle–ovary interrelationships affect the outcome of in vitro culture. From all these attempts, however, new ideas arise, and the goal of assuring the preservation of female reproductive potential appears a more realistic possibility. This review surveys and discusses advances and challenges of these technologies that, starting from a simple attempt, are now approaching the biosynthesis of a functional engineered ovary.

Abstract
OBJECTIVE To study whether follicular growth and oocyte maturation can be improved by antimüllerian hormone (AMH) modulation at specific stages of follicular development. DESIGN Primary and secondary follicles were cultured in a matrix-free system and were assigned to the control group and the group with AMH supplementation during the preantral stage and neutralizing AMH antibody addition during the antral stage. SETTING National primate research center. ANIMAL(S) Adult, female rhesus macaques (Macaca mulatta). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Follicle survival, growth, steroid and paracrine factor production, and oocyte competence were evaluated. Follicles were assessed for expression of genes that are critical for gonadotropin signaling, cumulus cell glycolysis, and oocyte quality. RESULT(S) Primary follicles formed "organoids" and developed to the antral stage in group culture. AMH exposure during the preantral stage increased organoid diameters. Oocytes from the AMH-treated organoids had greater diameters and matured to the metaphase II (MII) stage. Secondary follicles developed to the antral stage during individual culture. The AMH exposure during the preantral stage and AMH antibody treatment during the antral stage increased follicle diameters, vascular endothelial growth factor and follistatin production, differentiation factor 9 expression, and oocyte diameters. The MII oocytes from the AMH-modulated group developed to the morula stage after IVF, with one to the blastocyst stage. CONCLUSION(S) AMH supplementation at the preantral stage and depletion at the antral stage enhanced primate follicular development and oocyte competence in vitro. The improved embryonic development supports in vitro follicle maturation as a potential approach for fertility preservation.

Abstract
One of the most important concerns cancer survivors face is fertility. Current treatment modalities often result in damage to the reproductive system. Different options have been proposed to preserve the fertility of affected women, and many attempts have been made to improve their chance of childbearing after therapy. Cryopreservation of ovarian tissue and follicles before the onset of cancer treatment and then either transplantation of ovarian tissue or culture of ovarian tissue and individual follicles in vitro is a commonly cited approach. Extensive research is being done to design an optimal condition for the culture of ovarian follicles. Improving follicle culture systems by understanding their actual growth needs might be a crucial step toward fertility preservation in cancer patients. This review article will try to provide a summary of the role of different factors and conditions on growth of human and bovine preantral follicles in vitro.

Abstract
Objective The aim of the present study was to examine whether lysophosphatidic acid (LPA) could decrease cell death and improve in vitro culture (IVC) conditions in cultured vitrified mouse ovarian tissue. Materials and Methods In this experimental study, we collected and randomly divided 7-day-old mouse ovarian tissues into vitrified and non-vitrified groups. The ovaries were cultured in the presence and absence of LPA for one week. Morphology and follicular development were evaluated by hematoxylin and eosin (H&E) and Masson's trichrome (MTC) staining. The incidence of cell death was assessed by flow cytometry using annexin V/propidium iodide (PI) and a caspase-3/7 assay in all studied groups. Results The vitrified groups had a significantly decreased follicle developmental rate compared to the non-vitrified groups (P<0.05). Overall, qualitative and quantitative results showed prominent follicular degeneration in the vitrified groups compared with the respective non-vitrified groups. Both LPA treated groups had a significantly higher proportion of preantral follicles compared to the non-LPA treated groups (P<0.05). Flow cytometry analysis results showed significantly greater early and late apoptotic cells in all groups (17.83 ± 8.80%) compared to necrotic cells (7.97 ± 0.92%, P<0.05). The percentage of these cells significantly increased in the vitrified groups compared with non-vitrified groups. LPA treated groups had a lower percentage of these cells compared to non-LPA treated groups (P<0.05). The lower enzyme activity was observed in non-vitrified (especially in the LPA+ groups) cultured ovaries compared to the vitrified group (P<0.05). Conclusion Both vitrification and IVC adversely affected cell survival and caused cell death. We postulated that LPA supplementation of culture medium could improve the developmental rate of follicles and act as an anti-cell death factor in non-vitrified and vitrified ovarian tissues. It could be used for in vitro maturation of ovarian tissue.

Abstract
OBJECTIVE(S) We aimed to analyze if anti-apoptotic agent sphingosine-1-phosphate offers protection against in vitro follicle atresia during culture of human ovarian cortical samples. STUDY DESIGN A translational research study of ex-vivo and in-vitro models of human ovarian tissue. MATERIAL AND METHODS Ovarian cortical tissue fragments (1 × 0.5 cm) were obtained from young patients (n = 15 mean age ± SD: 29.4 ± 2.5) undergoing laparoscopic excision of benign ovarian cysts. The samples were cultured for 4 days in 24-well format culture plate using conventional culture techniques. S1P was added to culture media at 200 and 400 μM concentrations. At the end of culture period the samples were processed for both histomorphological assessment and detection of apoptosis with immunohistochemistry and western blot methods using apoptosis marker cleaved caspase-3. In vitro estradiol (E2) and AMH productions of the samples were measured with ELISA. Follicle counts were expressed as the mean number of follicles per mm2. RESULTS The mean numbers of primordial and secondary follicles were 3.2 ± 0.4 and 0.7 ± 0.2 respectively, in the fresh fixed uncultured samples. After four days of culture their numbers were significantly decreased to 0.8 ± 0.2 (p < 0.01) and 0.1 ± 0.05 (p < 0.05) respectively, in the control samples cultured without S1P compared to fresh fixed samples. S1P treatment decreased follicle atresia and significantly higher number of primordials (2.3 ± 0.3, p < 0.01) and secondary follicles (0.5 ± 0.1, p < 0.05) survived in the samples after 4 day culture period compared to those cultured without S1P. In line with this there was dose-dependent decrease in the protein expression of cleaved caspase-3 on western blot and in the number of apoptotic follicles stained positive for cleaved caspase-3 on immunohistochemistry in the samples incubated with S1P at 200 and 400 μM concentrations. Furthermore, those samples incubated with S1P produced significantly higher amounts of E2 (2339 ± 321 vs. 1156 ± 125 pg/mL respectively, p < 0.01) compared to control samples. CONCLUSIONS These results suggest that S1P promotes follicle survival in human ovarian cortical samples in vitro.

Abstract
Precise control of mammalian oogenesis has been a traditional focus of reproductive and developmental biology research. Recently, new reports have introduced the possibility of obtaining functional gametes derived in vitro from stem cells. The potential to produce functional gametes from stem cells has exciting applications for regenerative medicine though still remains challenging. In mammalian females ovulation and fertilization is a privilege reserved for a small number of oocytes. In reality the vast majority of oocytes formed from primordial germ cells (PGCs) will undergo apoptosis, or other forms of cell death. Removal occurs during germ cell cyst breakdown and the establishment of the primordial follicle (PF) pool, during the long dormancy at the PF stage, or through follicular atresia prior to reaching the ovulatory stage. A way to solve this limitation could be to produce large numbers of oocytes, in vitro, from stem cells. However, to recapitulate mammalian oogenesis and produce fertilizable oocytes in vitro is a complex process involving several different cell types, precise follicular cell-oocyte reciprocal interactions, a variety of nutrients and combinations of cytokines, and precise growth factors and hormones depending on the developmental stage. In 2016, two papers published by Morohaku et al. and Hikabe et al. reported in vitro procedures that appear to reproduce efficiently these conditions allowing for the production, completely in a dish, of a relatively large number of oocytes that are fertilizable and capable of giving rise to viable offspring in the mouse. The present article offers a critical overview of these results as well as other previous work performed mainly in mouse attempting to reproduce oogenesis completely in vitro and considers some perspectives for the potential to adapt the methods to produce functional human oocytes.

Mammalian fetal ovaries contain numerous primordial germ cells (PGCs), although few mature oocytes are obtained from females, owing to apoptosis and follicle atresia. The regulatory mechanisms underlying oogenesis/folliculogenesis remain unknown. Development of methods for obtaining mature oocytes from PGCs in fetal ovaries in vitro could contribute to clarifying these mechanisms. The failure of follicle assembly has been found to be the most challenging aspect in conventional culture conditions. Recently, we established novel culture conditions that enable successful follicle assembly, sustaining interactions between the oocyte and somatic cells, and, in turn, promoting oocyte growth and maturation. Mature oocytes were differentiated from PGCs after a 1-month culture period. A hundred mouse offspring were obtained from approximately a thousand mature oocytes, indicating that oocytes that were differentiated from PGCs in vitro acquired totipotency after fertilization. Here we provide a detailed protocol for using this in vitro system. This in vitro system will potentially provide a novel platform for studying oogenesis and preservation of female germ cells.

Abstract
Obtaining and fertilizing mature oocytes from immature follicles that were grown outside the body has conceptually attracted scientists for centuries, with initial attempts first documented in the 19th century. Significant progress has been made since then, due in part to a better understanding of folliculogenesis and improved techniques of in vitro follicle growth. Indeed, in vitro growth is now considered a reasonable approach to preserve or restore fertility when immature follicles and their oocytes need to be grown and matured outside the body. Certain patients would benefit from in vitro follicle growth, particularly those who carry a risk of cancer re-seeding after grafting of frozen-thawed ovarian tissue or who are at the risk of premature ovarian failure due to several intrinsic ovarian defects and genetic mutations that lead to accelerated follicle atresia and early exhaustion of the ovarian reserve. This review provides an update on the current status of in vitro growth of preantral human follicles, from initial efforts to the most recent achievements.

Abstract
Emerging additive manufacturing techniques enable investigation of the effects of pore geometry on cell behavior and function. Here, we 3D print microporous hydrogel scaffolds to test how varying pore geometry, accomplished by manipulating the advancing angle between printed layers, affects the survival of ovarian follicles. 30° and 60° scaffolds provide corners that surround follicles on multiple sides while 90° scaffolds have an open porosity that limits follicle-scaffold interaction. As the amount of scaffold interaction increases, follicle spreading is limited and survival increases. Follicle-seeded scaffolds become highly vascularized and ovarian function is fully restored when implanted in surgically sterilized mice. Moreover, pups are born through natural mating and thrive through maternal lactation. These findings present an in vivo functional ovarian implant designed with 3D printing, and indicate that scaffold pore architecture is a critical variable in additively manufactured scaffold design for functional tissue engineering.

Abstract
Various complex molecular events in oogenesis cannot be observed in vivo. As a bioengineering technique for female reproductive tissues, in vitro culture systems for female germ cells have been used to analyze oogenesis and preserve germ cells for over 20 years. Recently, we have established a new methodological approach for the culture of primordial germ cells (PGCs) and successfully obtained offspring. Our PGC culture system will be useful to clarify unresolved mechanisms of fertility and sterility from the beginning of mammalian oogenesis, before meiosis. This review summarizes the history of culture methods for mammalian germ cells, our current in vitro system, and future prospects for the culture of germ cells.

Abstract
Reconstituting gametogenesis in vitro is a key goal for reproductive biology and regenerative medicine. Successful in vitro reconstitution of primordial germ cells and spermatogenesis has recently had a significant effect in the field. However, recapitulation of oogenesis in vitro remains unachieved. Here we demonstrate the first reconstitution, to our knowledge, of the entire process of mammalian oogenesis in vitro from primordial germ cells, using an estrogen-receptor antagonist that promotes normal follicle formation, which in turn is crucial for supporting oocyte growth. The fundamental events in oogenesis (i.e., meiosis, oocyte growth, and genomic imprinting) were reproduced in the culture system. The most rigorous evidence of the recapitulation of oogenesis was the birth of fertile offspring, with a maximum of seven pups obtained from a cultured gonad. Moreover, cryopreserved gonads yielded functional oocytes and offspring in this culture system. Thus, our in vitro system will enable both innovative approaches for a deeper understanding of oogenesis and a new avenue to create and preserve female germ cells.

Abstract
OBJECTIVE To investigate the localization and function of gremlin-2 during human ovarian folliculogenesis. STUDY DESIGN Ovarian tissue from a gynecologic cancer patient was cultured in the presence or absence of gremlin-2 and then analyzed histologically. Growing follicles were counted by the microscopic observations of ovarian histological sections. Immunocytochemical staining was carried out to detect the expression of bone morphogenetic protein (BMP) 4 and phosphorylated Smad 1/5/8 (p-Smad 1/5/8). RESULTS Gremlin-2 was detected in human primordial, primary, and early growing follicles before culture. By day 4 of culture, the follicle growth rate in the presence of gremlin-2 (13.7%; 24/175) was significantly lower than that of the control (54.8%; 92/175; p<0.01). BMP4 expression was similar in the presence and absence of gremlin-2, whereas the p-Smad 1/5/8 signal was noticeably stronger in the absence of gremlin-2 in primordial and early-stage growing follicles. CONCLUSIONS Gremlin-2 maintains the follicle store as primordial follicles by suppressing Smad 1/5/8 signaling in the human ovary. The data presented here provide potential insight into reproductive medicine for cases of intractable infertility, such as premature ovarian insufficiency and cancer survivors.

Abstract
In the present review, the main strategies of female fertility preservation are covered. Procedures of fertility preservation are necessary for women who suffer from diseases whose treatment requires the use of aggressive therapies, such as chemotherapy and radiotherapy. These kinds of therapy negatively influence the health of gametes and their progenitors. The most commonly used method of female fertility preservation is ovarian tissue cryopreservation, followed by the retransplantation of thawed tissue. Another approach to female fertility preservation that has been actively developed lately is the ovarian tissue in vitro culture. The principal methods, advantages and drawbacks of these two strategies are discussed in this article.

Abstract
In vitro growth of immature oocytes provides opportunities to increase gametic resources and
to understand the mechanisms underlying oocyte development. Many studies on the in vitro
growth of oocytes have been reported thus far; however, only a few cases have been reported, which
demonstrated that oocytes can support full-term development after in vitro fertilization. Our
research group recently found that culture of mouse neonatal primordial follicles increased the birthrate;
however, the establishment of an in vitro system that can completely mimic follicle or oocyte
growth in vivo and control oogenesis remains an ongoing challenge.

Abstract
Background Successful early folliculogenesis is crucial for female reproductive function. It requires appropriate gene specific expression of the different types of ovarian cells at different developmental stages. To date, most gene expression studies on the ovary were conducted in rodents and did not distinguish the type of cell. In mono-ovulating species, few studies have addressed gene expression profiles and mainly concerned human oocytes. Results We used a laser capture microdissection method combined with RNA-seq technology to explore the transcriptome in oocytes and granulosa cells (GCs) during development of the sheep ovarian follicle. We first documented the expression profile of 15 349 genes, then focused on the 5 129 genes showing differential expression between oocytes and GCs. Enriched functional categories such as oocyte meiotic arrest and GC steroid synthesis reflect two distinct cell fates. We identified the implication of GC signal transduction pathways such as SHH, WNT and RHO GTPase. In addition, signaling pathways (VEGF, NOTCH, IGF1, etc.) and GC transzonal projections suggest the existence of complex cell-cell interactions. Finally, we highlighted several transcription regulators and specifically expressed genes that likely play an important role in early folliculogenesis. Conclusions To our knowledge, this is the first comprehensive exploration of transcriptomes derived from in vivo oocytes and GCs at key stages in early follicular development in sheep. Collectively, our data advance our understanding of early folliculogenesis in mono-ovulating species and will be a valuable resource for unraveling human ovarian dysfunction such as premature ovarian failure (POF).
