Abstract
The process of mammalian reproduction involves the development of fertile germ cells in the testis and ovary, supported by the surrounders. Fertilization leads to embryo development and ultimately the birth of offspring inheriting parental genome information. Any disruption in this process can result in disorders such as infertility and cancer. Chemical toxicity affecting the reproductive system and embryogenesis can impact birth rates, overall health, and fertility, highlighting the need for animal toxicity studies during drug development. However, the translation of animal data to human health remains challenging due to interspecies differences. In vitro culture systems offer a promising solution to bridge this gap, allowing the study of mammalian cells in an environment that mimics the physiology of the human body. Current advances on in vitro culture systems, such as organoids, enable the development of biomaterials that recapitulate the physiological state of reproductive organs. Application of these technologies to human gonadal cells would provide effective tools for drug screening and toxicity testing, and these models would be a powerful tool to study reproductive biology and pathology. This review focuses on the 2D/3D culture systems of human primary testicular and ovarian cells, highlighting the novel approaches for in vitro study of human reproductive toxicology, specifically in the context of testis and ovary.

Abstract
Extracellular vesicles (EVs) play an important role in the development and function of mammalian ovarian follicles. However, the mechanisms by which they are taken up by the follicular granulosa cells remain unclear. In addition, while oocytes play a pivotal role in follicular development, the possible interactions between oocyte-derived paracrine factors (ODPFs) and EV signals are unknown. Therefore, this study aimed to elucidate the mechanism of EV uptake and the effects of ODPFs on EV uptake by follicular somatic mural granulosa cells in mice. Fluorescence-labeled transferrin (TRF) and cholera toxin B (CTB), substrates for clathrin- and caveolae-mediated endocytosis, respectively, were taken up by mural granulosa cells in vitro. Their uptake was inhibited by Pitstop 2 and genistein, inhibitors of clathrin and caveolae pathways, respectively. Mural granulosa cells took up EVs, and this uptake was suppressed by Pitstop 2 and genistein. Moreover, ODPFs promoted the uptake of EVs and CTB, but not TRF, by mural granulosa cells. These results suggest that mural granulosa cells take up EVs through both clathrin- and caveolae-mediated endocytosis and that oocytes may promote caveolae-mediated endocytosis to facilitate the uptake of EVs.

Abstract
Granulosa-lutein cells (GLCs) from PCOS women display reduced HIF-1α and EDN2 levels, suggesting their role in PCOS etiology. Here, we investigated the mechanisms involved in aberrant EDN2 expression in PCOS, and its association with HIF-1α. Various HIF-1α-dependent factors were studied in GLCs from PCOS and compared to normally ovulating women. MicroRNA-210 (miR-210), its target genes (SDHD and GPD1L), and HIF-1α-responsive genes (EDN2 and VEGFA) differed in GLCs from PCOS, compared with those of healthy women. Levels of miR-210—designated hypoxiamiR—and EDN2 were reduced in the PCOS GLCs; concomitantly, GPD1L and SDHD levels were elevated. Cultured GLCs retained low EDN2 expression and had low HIF-1α levels, providing evidence for a disrupted hypoxic response in the PCOS GLCs. However, VEGFA expression was elevated in these cells. Next, miR-210 levels were manipulated. miR-210-mimic stimulated EDN2 twice as much as the miR-NC-transfected cells, whereas miR-210-inhibitor diminished EDN2, emphasizing the importance of hypoxiamiR for EDN2 induction. Intriguingly, VEGFA transcripts were reduced by both miR-210-mimic and -inhibitor, demonstrating that EDN2 and VEGFA are distinctly regulated. Disrupted hypoxic response in the GLCs of periovulatory follicles in PCOS women may play a role in ovulation failure, and in the reduced fertility prevalent in this syndrome.

Abstract
Granulosa cells are the cell population who have an increasing importance in the female genital system and reproduction. Thus, nowadays in vitro studies to address these cells are also gaining importance and attracts researcher's attention. The aim of our study is to develop a more feasible, low-cost granulosa cell isolation and culture method compared to methods defined so far. Granulosa cells were isolated from follicular fluids obtained from both healthy women donors (n = 19) and polycystic ovary syndrome (n = 15) applied to in vitro fertilization treatment process. Granulosa cells were isolated by using Lymphosep® separation fluid that was not used for this purpose before. The isolated cells were cultured in suitable culture dishes with a mixture of BIO-AMFTM-1 and DMEM/F12 in the first seeding and only complete DMEM/F12 in the following feeds. Complete medium contains only 5% fetal calf serum, 4% L-glutamine and 1% penicillin-streptomycin-amphotericin. The new methods we have developed in granulosa cell isolation and in vitro culture have been successful. Reduction in supplement types and amount; improved the proliferation rate of the granulosa cells in culture. Our new methods of isolation and cell culture for granulosa cells from healthy women, have been also successful in samples of polycystic ovarian patients. With these developed methods, granulosa cells, which belong to humans and have an important role in the ovary, could be isolated and subsequently be maintained to reproduce (proliferate) more easily and cheaper.

Abstract
BACKGROUND Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGCs) and other contaminating cell types. Several strategies, such as the antibody binding methods, the flask method, the cell strainer and positive selection of granulosa aggregates after density gradient (DG) centrifugation, were tested as LGC purification methods. Each of these strategies has its own advantages and disadvantages. Positive selection of granulosa aggregates after DG centrifugation is simple, rapid and efficient in terms of LGC recovery. However, it results in a low purity. Here, we aimed to test whether modifying the traditional protocol by collecting the aggregates from the FF, before the DG centrifugation could decrease the percentage of contaminating cells. MATERIALS AND METHODS In the present prospective study, 32 FF, from 32 women,were randomly assigned into one of the two purification techniques: positive selection of granulosa aggregates from the FF, after DG centrifugation (DG/ Agg, n=16) or positive selection of granulosa aggregates from the FF, before DG centrifugation (Agg/DG, n=16). At the end of each procedure cell count, vitality, morphology and purity of the cell suspension were evaluated. RESULTS No significant difference was detected in the total number of GCs between DG/Agg and Agg/DG (P>0.05). However, higher percentage of GCs with normal morphology was detected in Agg/DG compared to DG/Agg (P<0.001). Moreover, lower percentages of white blood cells (P<0.01), red blood cells (P<0.001) and epithelial cells (P<0.01) were identified in Agg/DG compared to DG/Agg. CONCLUSION Here we showed that positive selection of granulosa aggregates from the FF prior to DG technique had a higher purity compared to the traditional protocol. Thus, it could be a method of choice to prepare GCs for research purposes in clinical in vitro fertilization settings.

Abstract
Follicular fluid serves a crucial role in follicular development and oocyte maturation. Increasing evidence indicates that follicular fluid is rich in proteins and functional cells. In addition to oocyte cells, follicular fluid contains granulosa, thecal and ovarian surface epithelial cells. Granulosa cells (GCs) represent the predominant somatic cell type of the ovarian follicle and are involved in steroidogenesis and folliculogenesis. However, the long-term culture of GCs in vitro remains challenging. The present study aimed to extend the culture of GCs in vitro. Human GCs were collected from the follicular fluid of patients included in an in vitro fertilization program and cultured in the presence of conditioned medium obtained from mouse embryonic fibroblasts. GCs were cultured for over a year and 130 passages, and the population doubling time was ~22 h. Cells presented epithelial-like morphology and a cobblestone-like appearance when they reached confluence. Flow cytometric analysis demonstrated that cells expressed CD29, CD166 and CD49f but not CD31, CD34, CD45, CD90, CD105 or CD13. Immunofluorescence staining revealed that cells expressed follicle stimulating hormone receptor, luteinizing hormone receptor and cytochrome P450 aromatase, which was confirmed by reverse transcription-quantitative polymerase chain reaction. In the presence of androstenedione, cells secreted estradiol. In addition, estradiol level was further stimulated by dibutyryl cAMP treatment. In addition, intracellular cAMP and progesterone expression levels were upregulated by follicle stimulating hormone and/or human chorionic gonadotropin. Furthermore, cells survived in severe combined immunodeficiency mice following intra-ovarian injection. Histological analysis revealed that certain cells formed follicle-like structures. The results from the present study suggested that immortalized GCs may be a useful tool for further research on GC and improve the clinical application of drugs such as follicle-stimulating hormone or human chorionic gonadotropin.

Abstract
After removal of oocytes for in vitro fertilization, follicular aspirates which are rich in somatic follicular cells are discarded in daily medical practice. However, there is some evidence that less differentiated cells with stem cell characteristics are present among aspirated follicular cells (AFCs). The aim of this study was to culture AFCs in vitro and to analyze their gene expression profile. Using the RT2 Profiler PCR array, we investigated the expression profile of 84 genes related to stemness, mesenchymal stem cells (MCSs), and cell differentiation in AFCs enriched by hypoosmotic protocol from follicular aspirates of infertile women involved in assisted reproduction programme in comparison with bone marrow-derived mesenchymal stem cells (BM-MSCs) and fibroblasts. Altogether the expression of 57 genes was detected in AFCs: 16 genes (OCT4, CD49f, CD106, CD146, CD45, CD54, IL10, IL1B, TNF, VEGF, VWF, HDAC1, MITF, RUNX2, PPARG, and PCAF) were upregulated and 20 genes (FGF2, CASP3, CD105, CD13, CD340, CD73, CD90, KDR, PDGFRB, BDNF, COL1A1, IL6, MMP2, NES, NUDT6, BMP6, SMURF2, BMP4, GDF5, and JAG1) were downregulated in AFCs when compared with BM-MSCs. The genes which were upregulated in AFCs were mostly related to MSCs and connected with ovarian function, and differed from those in fibroblasts. The cultured AFCs with predominating granulosa cells were successfully in vitro differentiated into adipogenic-, osteogenic-, and pancreatic-like cells. The upregulation of some MSC-specific genes and in vitro differentiation into other types of cells indicated a subpopulation of AFCs with specific stemness, which was not similar to those of BM-MSCs or fibroblasts.

Abstract
PURPOSE To develop an optimal method of isolation and purification of human granulosa cells from ovarian follicular fluid. METHODS Follicular fluid was collected from patients undergoing oocyte retrieval. A series of isolation and purification techniques was performed, involving density gradient centrifugation and use of different antibody-bead complexes. RESULTS The highest percent yield of live purified granulosa cells came from density gradient centrifugation using sucrose polymer followed by positive selection of granulosa cells using primary antibody to MISRII and secondary antibody coupled to iron oxide beads. CONCLUSIONS A novel protocol for granulosa cell purification has been developed yielding samples that are largely free of nondesirable cells. This protocol provides a purification solution, especially for patient samples that have significant RBC contamination.

Abstract
Communication between various ovarian cell types is a prerequisite for folliculogenesis and ovulation. In antral follicles granulosa cells divide into two distinct populations of mural and cumulus granulosa cells (CGC), enveloping the antrum and surrounding the oocyte, respectively. Both cell types, with the mural compartment in excess, contribute to the floating granulosa cell (FGC) population in the follicular fluid. The aim of this study was to compare the transcriptomes of FGC and CGC in stimulated antral follicles obtained from 19 women undergoing IVF-ICSI procedure. FGC were obtained from follicular fluid during the follicle puncture procedure and CGC were acquired after oocyte denudation for micromanipulation. Gene expression analysis was conducted using the genome-wide Affymetrix transcriptome array. The expression profile of the two granulosa cell populations varied significantly. Out of 28 869 analysed transcripts 4480 were differentially expressed (q-value < 10(-4)) and 489 showed > or =2-fold difference in the expression level with 222 genes up-regulated in FGC and 267 in CGC. The transcriptome of FGC showed higher expression of genes involved in immune response, hematological system function and organismal injury, although CGC had genes involved in protein degradation and nervous system function up-regulated. Cell-to-cell signalling and interaction pathways were noted in both cell populations. Furthermore, numerous novel transcripts that have not been previously described in follicular physiology were identified. In conclusion, our results provide a solid basis for future studies in follicular biology that will help to identify molecular markers for oocyte and embryo viability in IVF.

Abstract
The major functions of granulosa cells (GCs) include the production of steroids, as well as a myriad of growth factors to interact with the oocyte during its development within the ovarian follicle. Also FSH stimulates GCs to convert androgens (coming from the thecal cells) to estradiol by aromatase. However, after ovulation the GCs produce progesterone that may maintain a potential pregnancy. Experiments with human GCs are mainly focused on the purification of GCs from ovarian follicular fluid followed by FACS analysis or short-term cultivation. The aim of our study was to cultivate GCs for a long period, to characterize their morphology and phenotype. Moreover, we have cultivated GCs under gonadotropin stimulation in order to simulate different pathological mechanisms during folliculogenesis (e.g. ovarian hyperstimulation syndrome). GCs were harvested from women undergoing in vitro fertilization. Complex oocyte-cumulus oophorus was dissociated by hyaluronidase. The best condition for transport of GCs was optimized as short transport in follicular fluid at 37 degrees C. GCs expansion medium consisted of DMEM/F12, 2% FCS, ascorbic acid, dexamethasone, L-glutamine, gentamycine, penicillin, streptomycin and growth factors (EGF, bFGF). GCs transported in follicular fluid and cultivated in 2% FCS containing DMEM/F12 medium supplemented with follicular fluid presented increased adhesion, proliferation, viability and decreased doubling time. Cell viability was 92% and mean cell doubling time was 52 hrs. We have optimized transport and cultivation protocols for long-term cultivation of GCs.

Abstract
Nitric oxide (NO) in bovine ovary has been characterized as one of the controllers of granulosa cells' (GC) steroidogenesis and apoptosis. One of the pathways used by NO to have these effects is cGMP. The objectives of the present study were to verify the effect of sodium nitroprusside (SNP), a NO donor, on steroidogenesis, cell viability (mitochondrial activity) and GC cell cycle distribution and if this effect occurs by the NO-cGMP signaling pathway with the addition of SNP with or without 1H-[1,2,3] oxadiaziolo[4,3a]quinoxaline-1-one (ODQ), a selective soluble guanylate cyclase inhibitor. The antral GC from 3 to 5mm diameter cattle follicles was cultured without treatment (control), with ODQ (10(-4)M) and 10(-5), 10(-3) and 10(-1)M SNP with or without ODQ for 24h. Nitrate/nitrite (NO(3)(-)/N0(2)(-)) concentrations were evaluated by Griess method, progesterone (P(4)) and 17beta-estradiol (E(2)) concentrations by chemiluminescence, viability and cell cycle stage by MTT method (3-[4,5-dimethylthiazol-2yl]-2,3 dipheniltetrazolium bromide) and flow cytometry, respectively. Nitrate/nitrite concentration in culture medium increased (P<0.05) in a dose-dependent manner according to SNP concentration added to the culture medium. The GC cultured without treatment, with ODQ and with 10(-5)M SNP in the presence or absence of ODQ developed into cell aggregates and did not vary in cell viability (P>0.05), while GC cultured with 10(-3) and 10(-1)M SNP with or without ODQ presented disorganized GC aggregates or did not develop into cell aggregates and also had substantially decreased cell viability (mitochondrial activity inhibition) and steroids synthesis (P<0.05), and effects were not reversed with us of ODQ. Most GC cultured without treatment (control) or with ODQ, 10(-5) and 10(-3)M SNP with or without ODQ were in the G0/G1 (80-75%) stage and in a lesser proportion (20-25%) in the S+G2/M stage of the cell cycle, while the 10(-1)M SNP treatment resulted in GC in G1 phase arrest. The treatment with 10(-5)M SNP increased (P<0.05) E(2) synthesis and inhibited (P<0.05) progesterone synthesis. The addition of ODQ reversed (P<0.05) the stimulatory effect of 10(-5)M SNP treatment on E(2), but not on P(4) synthesis (P>0.05). These results demonstrated that E(2) synthesis by antral GC from small follicles is modulated by lesser NO concentrations via the cGMP pathway, but not P(4) while steroids inhibition cGMP pathway independent, mitochondrial damage and the interference on cell cycle progression caused by greater NO concentration can lead to cell death.

Abstract
BACKGROUND Cells isolated from the periovulatory ovarian follicle are often used as a model of ovarian steroidogenesis and corpus luteum formation. The follicular fluid-derived cell (FFDC) population is, however, heterogeneous and in addition to granulosa-lutein cells, non-steroidogenic cells are also present. These non-steroidogenic cells, especially the immune cells, may have important biological functions in this model. Here, we describe a method to isolate FFDC, characterize the phenotype of the immune cells and deplete immune cells from FFDC. METHODS AND RESULTS Follicular fluid aspirated transvaginally during IVF was clarified by centrifugation and enzymatic dispersion, labelled for leukocyte-specific markers and analysed by flow cytometry. Leukocytes constituted 22% of FFDC and expressed macrophage/dendritic cell, monocyte and lymphocyte markers. Leukocytes were depleted with anti-CD45-conjugated immunobeads, resulting in an FFDC population with <1.9% leukocytes. Leukocyte-containing FFDC secreted more interleukin-8 in culture than leukocyte-depleted FFDC. CONCLUSION Leukocyte-depleted FFDC may serve as a useful model to study the interaction of immune cells and luteinizing cells during corpus luteum formation.

Abstract
Human follicular fluid can provide a source of human granulosa cells for scientific study. However, removing potentially contaminating cells, such as white and red blood cells, is important for molecular and in vitro studies. We have developed a purification technique for human granulosa cells based on the selection of cellular aggregates. Human granulosa cells from 21 IVF patients were collected. A 50% Percoll gradient was used to remove red blood cells, and granulosa cell aggregates were collected, washed and processed for histology, electron microscopy, flow cytometry analysis, cell culture and RNA extraction. Granulosa cell aggregates were found to be homogeneous and free of white blood cells after histological and electron microscopic analysis. White blood cell contamination, measured by flow cytometry, was found to be between 2 and 4%. Polymerase chain reaction analysis revealed expression of known human granulosa cell genes and a white blood cell marker. Human granulosa cells grown in vitro showed flattened fibroblast-like morphology with lipid droplets consistent with previous reports. Cultured cells expressed the FSH receptor. Selection of human granulosa cell aggregates following centrifugation through a Percoll gradient provides an efficient method of selecting granulosa cells, suitable for both molecular and in vitro studies.

Abstract
PURPOSE To validate an expedited method for the removal of erythrocytes when preparing IVF granulosa-luteal cells for culture. METHODS Granulosa cells were enriched for culturing from follicular aspirates by density gradient centrifugation and by hypo-osmotic lysis treatments. RESULTS Cells prepared by either method showed the same cell viability and produced progesterone in similar quantities. CONCLUSIONS Using hypo-osmotic lysis to remove erythrocytes does not impair granulosa cell viability or steroidogenesis. It avoids multiple density gradient centrifugations and washings, and yields IVF granulosa cells ready for culture efficiently.

Abstract
BACKGROUND Follicular aspirates represent a snapshot in time of conditions within the follicle at oocyte retrieval in women undergoing in vitro fertilization and embryo transfer. This clinical material has been much investigated and yet its cellular composition remains unclear. In this study we investigated the origin and profile of leukocytes found within follicular aspirates. METHODS We performed morphological and immunohistochemical analyses of follicular aspirates and peripheral blood obtained concurrently at oocyte retrieval. RESULTS There was no correlation between erythrocyte and leukocyte numbers in follicular aspirates. The profile of leukocyte subtypes within follicular aspirates was variable and differed significantly from the peripheral circulation in a significant proportion of the analysed samples. A subset of follicular aspirates displayed a marked increase in monocytes/macrophages and an apparent concomitant reduction in polymorphonuclear leukocytes compared with peripheral blood. CONCLUSIONS Leukocytes within follicular aspirates cannot be accounted for solely as a result of blood vessel damage during oocyte retrieval. The variation in leukocyte subtypes observed in some follicular aspirates may reflect a coordinated infiltration of these cells, characteristic of progressive inflammatory responses in other systems. The possibility that leukocyte variation is indicative of follicular maturation deserves further investigation due to its potential relevance in optimizing oocyte selection.

Abstract
The nerve growth factor-induced clone B (NGFI-B) family of transcription factors are orphan members of the steroid hormone receptor superfamily. The NGFI-B expression was recently shown in the rat ovarian tissue and appears to be regulated by gonadotrophins. The purpose of our study was to investigate the role of the three members of this family [NGFI-B, Nur-related factor 1 (NURR1) and neuron derived orphan receptor 1 (NOR-1)] in the transcription of genes that encode key steroidogenic enzymes and examine expression in the human ovary. Real-time RT-PCR was used to quantify mRNA expression levels of the NGFI-B family members in human ovarian follicles, corpora lutea and in human granulosa cells after FSH, phorbol ester (TPA) and forskolin treatment. NGFI-B was expressed at higher levels than both NURR1 and NOR-1 in both ovarian follicles and corpora lutea. In human granulosa tumour (HGT) cells, the NGFI-B expression increased after TPA, and to a lesser extent, after forskolin treatment. Treatment of primary cultures of human granulosa cells with forskolin and FSH rapidly increased the NGFI-B mRNA levels followed by an increase in 3beta-hydroxysteroid dehydrogenase type 2 (HSD3B2). Transcription of HSD3B2 was studied by transfecting NGFI-B and steroidogenic factor 1 (SF1) expression vectors with reporter constructs prepared with human steroidogenic acute regulatory protein, cholesterol side-chain cleavage, and HSD3B2 genes. NGFI-B increased the transcription of HSD3B2 in HGT cells which is significantly more than SF1. Mutation or deletion of the NGFI-B response element in the HSD3B2 promoter significantly reduced the NGFI-B-mediated transcription of HSD3B2. Therefore, our data suggest that the NGFI-B may play a significant role in up-regulation of HSD3B2 that leads to the increase in progesterone production that is seen in granulosa cells at ovulation.

Abstract
Sex hormone-binding globulin (SHBG) was classically thought to be a plasma steroid-carrying protein of hepatic origin, but recently, locally produced, membrane-bound SHBG has been shown to influence cell functions in several steroid-responsive tissues. In the ovary, SHBG is known to be present in the follicular fluid, but information about a possible intracellular presence of SHBG in this organ is still very scarce. In this study the presence of SHBG was assessed by immunohistochemistry in human granulosa-lutein cells (GLC) collected by follicle puncture for in vitro fertilization. SHBG was detected in the cytoplasm of GLC before and after in vitro culture for up to 96 h. The presence of full-length SHBG messenger RNA was demonstrated in GLC by reverse transcription-polymerase chain reaction (RT-PCR) in both cultured and uncultured cells. These results demonstrate a local synthesis of SHBG in GLC and raise the question of the physiological significance of these findings in follicular physiology.

Abstract
Prospective and retrospective clinical trials suggest a decreased oocyte and embryo quality in women with endometriosis. Based on these observations, the authors described an altered intrafollicular milieu in endometriosis, which explains the bad quality oocytes and the resulting embryos with lower capacity to implant. Whether these changes affect the oocytes or are the consequence of genomic alterations manifested by biochemical and chromosomal differences in healthy women is an unresolved issue. If the effects of endometriosis on follicular development are nongenomic in origin, modulation of the process of folliculogenesis may be sufficient to treat the disease and cure infertility associated with endometriosis. A genomic defect needs specific genetic therapy, which currently is not available.

Abstract
PURPOSE To investigate the secretion of progesterone (P4) and corticosteroid binding globulin (CBG) by granulosa luteal cells (GC) as well as the mRNA levels of CBG and 3beta hydroxisteroid dehydrogenase (3beta HSD), in women with and without endometriosis in vivo and in vitro. METHODS Prospective study in a private, university-affiliated assisted reproduction unit, including women with severe endometriosis (n = 14) or without the disease (n = 20) undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer. GC were obtained from each follicle aspirated, pooled for each patient, and follicular and blood contaminating leukocytes depleted through immunomagnetic purification. Secreted P4 and CBG, and mRNA for both 3beta HSD and CBG were determined in vivo and in vitro using RIA and reverse transcription followed by competitive polymerase chain reaction (cRT-PCR). RESULTS The pattern of expression of 3beta HSD and CBG mRNAs in vivo and in vitro was similar in both groups. Also, GC from patients with endometriosis produced equal amounts of P4 and CBG than controls without the disease, either in freshly isolated cells or in 24-h cultures. CONCLUSIONS The GC function in terms of 3beta HSD and CBG mRNA expression and P4/CBG secretion does not seem to be altered in patients with endometriosis in comparison with those without this condition.

Abstract
The role of red and white blood cells in the regulation of porcine theca cell function is poorly understood. Interactions between these cell types and a potential mediator of any interaction, PDGF, were investigated using a serum-free culture system. Theca cells were collected from 6-9mm antral follicles and plated at 50x10(3) viable cells/well. In the first experiment, macrophages were removed and theca cells+/-macrophages were cultured with a range of PDGF doses (0.1, 1, and 10ng/ml)+/-IGF-1. In the second experiment, red blood cells were removed with lysing buffer. In both experiments the effect of treatment on steroidogenesis and viable cell number was examined. Macrophage removal decreased oestradiol production but increased androstenedione output irrespective of the presence of IGF-1 (oestradiol+/-IGF-1, P<0.001; androstenedione P=0.02 without IGF-1, P<0.001 with IGF-1). PDGF increased oestradiol synthesis by whole and macrophage-free theca cell preparations but only in the presence of IGF-1 (P<0.001). In contrast, androstenedione production was unaffected by PDGF dose in the presence of IGF-1 (P=0.67). Without IGF-1, 10ng/ml PDGF tended to decrease androstenedione levels (P=0.06). Macrophage removal increased viable cell number at 144h (P<0.001+/-IGF-1) as did PDGF (P<0.001+/-IGF-1). In the absence of IGF-1, there was a PDGF x cell type interaction (P=0.02). Macrophage-free cultures with 10ng/ml PDGF had twice as many viable cells as whole preparations with no PDGF. In the second experiment, red blood cell removal did not affect steroidogenesis or the number of viable cells present at 144h when cells were cultured with IGF-1. The data show that theca cell/macrophages interactions do occur, and influence both steroidogenesis and viable cell number during culture. The macrophage product(s) enhanced oestradiol synthesis but reduced androstenedione production and the number of viable cells. As all these interactions were not mimicked by PDGF, PDGF cannot be the only factor mediating the theca/macrophage interaction. When cultured under optimised conditions the presence of red blood cells was not detrimental to theca cell steroidogenesis or the number of viable cells.

Abstract
PURPOSE Our objective was to explain a relationship between concentrations of tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) in follicular fluid, oocyte quality, and outcomes of in vitro fertilization--embryo transfer (IVF-ET). METHODS The concentrations of TNF-alpha and NO were measured in 115 follicular fluid samples collected from 43 patients undergoing IVF-ET program, due to tubal obstruction, some with endometriosis (8 patients) or hydrosalpinx (5 patients). A correlation of these factors concentrations and the oocyte quality, the oocyte maturity, and infertility-associated diseases was analyzed. RESULTS No correlation was found between concentrations of NO and TNF-alpha in follicular fluid. NO concentrations in follicular fluids were significantly higher in patients with endometriosis (P < 0.001) or hydrosalpinx (P < 0.01) compared to the patients with just tubal obstruction. Follicular NO concentration differences according to oocyte maturity and oocyte quality were not found. In contrast, TNF-alpha concentrations in follicular fluids were significantly higher in poor quality oocytes (P < 0.05) but were not associated with infertility-associated diseases, such as hydrosalphinx or endometriosis,and the oocyte maturity. No significant differences in follicular levels of NO and TNF-alpha as well as IVF-ET parameters of pregnant and nonpregnant groups were revealed. CONCLUSIONS There is no significant correlation between the concentrations of NO and TNF-alpha in follicular fluid. NO levels in follicular fluid are altered in infertility-associated diseases. However, TNF-alpha levels but not NO levels influence oocyte quality. These results suggest that the production of NO and TNF-alpha in follicular fluid may be regulated via different pathways and can be tempered with infertility-associated diseases, thereby influencing oocyte quality locally.

Abstract
PROBLEM Expression of tumor necrosis factor-alpha (TNF) and interleukins 1 alpha and 1 beta (IL-1) have been reported in ovaries of several species and humans and are implicated in ovarian follicular development and atresia, ovulation, steroidogenesis, and corpus luteum function (including formation, development, and regression). The principal abnormal processes affected by these cytokines are ovarian cancer and reduction of ovarian function during sepsis. METHODS A literature review. RESULTS Numerous studies indicate that TNF and IL-1 inhibit gonadotropin-stimulated steroidogenesis of undifferentiated ovarian cells due to inhibition of adenylyl cyclase and post-cAMP sites. In differentiated ovarian cells, these cytokines either stimulate progesterone synthesis or have little to no effect on steroidogenesis. Both cytokines participate in ovulation and levels of these cytokines increase during the preovulatory period. Endotoxin inhibits gonadotropin-stimulated ovarian steroidogenesis and follicular development and these effects are mediated, in part, by TNF and by direct effects of endotoxin on ovarian cells. IN newly formed corpora lutea, progesterone secretion is inhibited by TNF and IL-1, although each has proliferative effects. TNF also has been implicated in regression of corpora lutea because TNF stimulates prostaglandin synthesis and luteal TNF increases after initiation of the decline in progesterone secretion. TNF and IL-1 are secreted by some ovarian cancer cells and stimulate growth of these cells. CONCLUSIONS Thus, TNF and IL-1 are multifunctional factors affecting various ovarian processes.

Abstract
OBJECTIVE The purpose of this study was to determine whether interferon gamma affects luteinized human granulosa cell progesterone, estrone, and estradiol production in the presence and absence of associated white blood cells by either cytotoxic or antiproliferative mechanisms. STUDY DESIGN Luteinized granulosa cells were isolated by Percoll centrifugation from women during in vitro fertilization cycles. Some cell suspensions were further treated with anti-CD45 magnetic immunobeads to remove associated white blood cells. Granulosa cells with and without white blood cells were cultured in the presence of interferon gamma (0.5 to 50 ng/ml) for 48 hours. Medium was changed at 24-hour intervals, and spent medium was assayed for progesterone, estrone, and estradiol. In separate experiments granulosa cell viability was assessed with the tetrazolium salt reduction assay. RESULTS Interferon gamma significantly inhibited granulosa cell progesterone production in both basal and human chorionic gonadotropin-stimulated cells cocultured with white blood cells in a concentration-dependent manner, whereas cells cultured free of white blood cells demonstrated less inhibition. In the absence of interferon gamma a more profound increase in granulosa cell progesterone synthesis was found in human chorionic gonadotropin-stimulated cultures without associated white blood cells. Interferon gamma inhibited granulosa cell estrone and estradiol production in basal cultures containing white blood cells in both a time- and concentration-dependent manner. Estrone production was not affected by interferon gamma in human chorionic gonadotropin-stimulated granulosa cell cultures containing white blood cells, whereas estradiol secretion was decreased at 48 hours with 50 ng/ml interferon gamma. Both estrone and estradiol synthesis were inhibited by 50 ng/ml interferon gamma in granulosa cell cultures free of white blood cells. In cultures free of interferon gamma, granulosa cell estrone and estradiol secretion was not affected by human chorionic gonadotropin stimulation compared with basal controls regardless of the presence or absence of white blood cells. All concentrations of interferon gamma used had no effect on granulosa cell viability at any time point tested. CONCLUSIONS Our data suggest that interferon gamma affects granulosa cell steroid production both independently and in synergy with associated white blood cells and further supports the hypothesis that interferon gamma may be an important intraovarian regulator of ovarian steroid production during the luteal phase.

Abstract
To evaluate the roles of interleukin-1 (IL-1) in regulation of ovarian prostaglandin (PG) synthesis, we examined the effects of IL-1 beta on PGE2, PGE2 alpha, 6-keto-PGF 1 alpha and thromboxane (TX) B2 synthesis in cultures of human ovarian granulosa cells. Granulosa cells were obtained from hyperstimulated follicles in patients undergoing oocyte retrieval for in vitro fertilization-embryo transfer (IVF-ET). IL-1 beta increased immunoreactive concentrations of PGE2 and PGF2 alpha in culture medium in time- and dose-dependent manners. Concentration of PGE2 was significantly higher after 24 h incubation with 5 or more units/ml of IL-1 beta, when compared to the control value obtained without IL-1 beta (P < 0.05). Concentration of PGF2 alpha was significantly higher after 8 h incubation with more than 2 units/ml of IL-1 beta (P < 0.05). The increase in PGE2 was observed even in the presence of human chorionic gonadotropin (hCG), and blocked by indomethacin, an inhibitor of cyclooxygenase. During a 10 day incubation period, stimulatory effects of IL-1 beta on PG synthesis were observed only on the first 2 days incubations. Concentrations of 6-keto-PGF 1 alpha and TXB2 were below our measurement limits. This study demonstrated that IL-1 beta stimulates PG synthesis in human ovarian granulosa cells in vitro. IL-1 seems to play an important role in regulating ovarian functions.

Abstract
OBJECTIVES To determine whether HLA-DR expression in the human ovary is controlled by endocrine or immune mediators, we examined the effects of several lectins, lymphokines, and hormones on granulosa cells in vitro. STUDY DESIGN HLA-DR antigens were detected by indirect immunofluorescence on granulosa cells obtained at oocyte retrieval for in vitro fertilization. RESULTS When cultured with concanavalin A, pokeweed mitogen, phytohemagglutinin, interleukin-1, or interleukin-2, granulosa cells failed to express HLA-DR antigens. Both interferon alfa and interferon beta induced only a modest expression of HLA-DR molecules (4.1% +/- 0.9% and 2.5% +/- 0.8%, respectively) in comparison with the marked increase in HLA-DR expression (25.2% +/- 2.8%), when granulosa cells were exposed to interferon gamma. The gonadotropins follicle-stimulating hormone and human chorionic gonadotropin alone were unable to induce HLA-DR antigens, but acted synergistically with interferon gamma to enhance expression in a dose-dependent manner. The addition of 0.1 and 10 IU/ml of follicle-stimulating hormone with 10,000 IU/ml of interferon gamma significantly increased expression by 11.5% +/- 2.5% and 15.5% +/- 2.7%, respectively, over that of interferon gamma alone. Similarly, 1 and 10 IU/ml of human chorionic gonadotropin produced a 7.8% +/- 2.0% and 12.4% +/- 2.2% increase in HLA-DR expression over baseline. CONCLUSION These studies demonstrate that factors from both the immune and endocrine systems can interact to control HLA-DR expression in the ovary.

Abstract
OBJECTIVES To investigate the possibility of local interleukin-1 (IL-1) and IL-1 inhibitor production by human granulosa and cumulus cells and to assess their direct effects on the steroidogenesis of these cells in vitro. DESIGN Prospective study. PARTICIPANTS Normal ovulatory women undergoing ovulation induction for in vitro fertilization. INTERVENTION Pretreatment of patients with gonadotropin-releasing hormone analogue, human menopausal gonadotropin, and human chorionic gonadotropin (hCG). MAIN OUTCOME MEASURES Retrieval and isolation of granulosa luteal cells and follicular fluid (FF). Granulosa luteal cells and cumulus cells cultured and analyzed by fluorescent activated cell sorter. Follicular fluid separated and bioassayed for IL-1 and IL-1 inhibitory activity. Steroid measurement performed. Interleukin-1 inhibitor purified. Interleukin-1 and IL-1 inhibitor bioassay performed. Statistical analysis made and interpreted. RESULTS Interleukin-1, but not IL-1 specific inhibitory activity, was found in granulosa and cumulus cell cultures and also in FF, only after its purification on a high-pressure liquid chromatography column. Under nonstimulated conditions, neither IL-1 nor IL-1 inhibitor had any effect on basal progesterone (P) or estradiol (E2) secretion. However, IL-1 inhibitor demonstrated significant (P < 0.01) inhibition of hCG-stimulated P secretion (from 200 to 110 ng/10,000 cells per 24 hours). In addition, IL-1 demonstrated a significant (P < 0.05) and dose-dependent inhibition of hCG-stimulated E2 production (from 6,832 +/- 460 to 4,237 +/- 141 pg/10,000 cells per 24 hours). CONCLUSIONS Interleukin-1 may exert a significant local autocrine regulatory role in the human ovary.
