Abstract
Objective Despite the developments of in vitro fertilization (IVF) protocols, implantation failure remains a challenging problem, owing to the unbalance between the embryo, endometrium, and immune system interactions. Effective treatments are urgently required to improve successful implantation. Recently, many researchers have focused on granulocyte colony-stimulating factor (G-CSF) to regulate immune response and embryo-endometrium cross-talk. However, previous studies have reported inconsistent findings on the efficacy of G-CSF therapy on implantation failure. The objective of this review was to further explore the effects of G-CSF according to administration dosage and timing among women who experienced at least one implantation failure. Methods We systematically searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Scopus, and Web of Science for randomized controlled trials of G-CSF on implantation failure up to July 21, 2023. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated and the heterogeneity of the studies with the I2 index was analyzed. Results We identified a total of 2031 studies and finally included 10 studies in the systematic review and meta-analysis. G-CSF administration improved the clinical pregnancy rate (CPR), implantation rate (IR), biochemical pregnancy rate (BPR), and live birth rate (LBR) in women with at least one implantation failure. Subgroup analyses showed that G-CSF treatment could exert good advantages in improving CPR [OR=2.49, 95%CI (1.56, 3.98), I2 = 0%], IR [OR=2.82, 95%CI (1.29, 6.15)], BPR [OR=3.30, 95%CI (1.42, 7.67)] and LBR [OR=3.16, 95%CI (1.61, 6.22), I2 = 0%] compared with the blank control group. However, compared with placebo controls, G-CSF showed beneficial effects on CPR [OR=1.71, 95%CI (1.04, 2.84), I2 = 38%] and IR [OR=2.01, 95%CI (1.29, 3.15), I2 = 24%], but not on LBR. In addition, >150μg of G-CSF treatment increased CPR [OR=2.22, 95%CI (1.47, 3.35), I2 = 0%], IR [OR=2.67, 95%CI (1.47, 4.82), I2 = 0%] and BPR [OR=2.02, 95%CI (1.17, 3.47), I2 = 22%], while ≤150μg of G-CSF treatment improved miscarriage rate (MR) [OR=0.14, 95%CI (0.05, 0.38), I2 = 0%] and LBR [OR=2.65, 95%CI (1.56, 4.51), I2 = 0%]. Moreover, G-CSF administration on the day of embryo transfer (ET) could increase CPR [OR=2.81, 95%CI (1.37, 5.75), I2 = 0%], but not on the day of ovum pick-up (OPU) or human chorionic gonadotropin (HCG) injection. Conclusion G-CSF has a beneficial effect on pregnancy outcomes to some extent among women who experienced at least one implantation failure, and the administration dosage and timing influence the effect size.Systematic review registration: https://www.crd.york.ac.uk/prospero/, identifier CRD42023447046.

Abstract
INTRODUCTION Approximately 17.5% of couples of reproductive age have experienced infertility. Women with a poor ovarian response (POR) must undergo in vitro fertilisation (IVF) and embryo transfer to achieve pregnancy. However, studies have reported a poor response to gonadotropin stimulation in women undergoing IVF-ET. Results from animal experiments suggest that granulocyte colony-stimulating factor (G-CSF) has a curative effect by protecting ovarian function, reducing follicle loss and delaying premature ovarian failure in rats caused by chemotherapy. Clinical studies on the therapeutic effect of G-CSF are deficient; therefore, this study will investigate its ability to improve ovum quality and maturity among women with POR undergoing IVF/intracytoplasmic sperm injection (ICSI). METHODS AND ANALYSIS This clinical, multicentre, triple-blind, placebo-controlled trial will employ balanced randomisation (1:1). The planned sample size is 312 participants (156 subjects in each group). A total of 312 patients with infertility undergoing IVF/ICSI will be recruited from four public hospitals in China. The participants will be randomly divided into an experimental group (G-CSF) and a placebo group (control). All patients will be treated by using the progestin-primed ovarian stimulation superovulation protocol. The primary outcome will be D3 embryo quality. The number of ova obtained, MII ova and transferable embryos will be inclusive in the secondary outcome. ETHICS AND DISSEMINATION To our knowledge, this is the first clinical trial to investigate the effect of G-CSF treatment timing and stimulation protocol in patients with POR in China. This study will provide new information about G-CSF efficacy among patients with POR undergoing IVF/ICSI and can help improve ovum quality and maturity. Clinical trials on this subject are deficient in China; therefore, a well-designed randomised trial is needed to determine the ability of G-CSF to improve ovum quality and maturity to facilitate conception among women with POR treated with IVF/ICSI. TRIAL REGISTRATION NUMBER ChiCTR2200062412.

Abstract
BACKGROUND Endometrial injury can result in thin endometrium and subfertility. Granulocyte macrophage colony stimulating factor (GM-CSF) contributes to tissue repair, but its role in endometrial regeneration has not been investigated. METHODS To determine the effect of GM-CSF on endometrial regeneration, we established a mouse model of thin endometrium by uterine perfusion with 20 μL 90% ethanol. Thin endometrium in mice was featured by lowered endometrial thickness, decreased expression of Ki67 in glandular cells, and a reduced number of implantation sites. To explore the mechanism of GM-CSF on endometrial regeneration, endometrium was obtained from patients undergoing hysterectomy or hysteroscopy and endometrial biopsy. Effects of GM-CSF on primary cultured human endometrial glandular and stromal cells were examined by the 5-bromo-2'-deoxyuridine (BrdU) proliferation assay and transwell migration assay, followed by exploration of the potential signaling pathway. RESULTS GM-CSF intraperitoneal (i.p.) injection significantly increased endometrial thickness, expression of Ki67 in endometrial glandular cells, and the number of implantation sites. GM-CSF significantly promoted proliferation of primary human endometrial glandular cells and migration of stromal cells. GM-CSF activated p-Akt and increased expressions of p70S6K and c-Jun, which were blocked by LY294002. CONCLUSION We found that GM-CSF could improve endometrial regeneration, possibly through activating PI3K/Akt signaling pathway.

Abstract
OBJECTIVE The aim of this meta-analysis is to explore the beneficial role of granulocyte colony-stimulating factor (G-CSF) on infertile women under artificial reproduction technology treatment. METHOD Medline, Embase and ISI Web of Science databases were searched to identify relevant randomized control trials. Studies before July, 2017 were included for primary screening. Meta-analysis of the total and subgroup patients was conducted, and relative risks (RRs) and their 95% confidence intervals (95% CI) were calculated by a fixed-effect model if no heterogeneity (evaluated as I2 statistic) existed. Otherwise, a random-effects model was adopted. Subgroup analysis was performed by administrating route or clinical indication. Egger test and influence analysis were conducted to evaluate the publication bias and study power, respectively. RESULTS The final selection enrolled 10 RCTs, involving 1016 IVF-ET cycles (521 distributed to the G-CSF group and 495 to the control). Compared with control group, G-CSF administration could significantly improve clinical pregnancy rate (CPR, RR 1.89, 95% CI 1.53-2.33), while it had no beneficial effect on embryo implantation rate (IR, RR 1.84, 95% CI 0.84-4.03). The subgroup analysis by administration route showed that both uterine infusion and subcutaneous injection can produce a substantial increase in CPR, with the pooled RRs (95% CI) 1.46 (1.04-2.05) and 2.23 (1.68-2.95), respectively. Nevertheless, most of included RCTs dealt with the RIF subjects, and the pooled analysis of this data showed a higher PR and IR in G-CSF group as compared to that in the control, with the RRs (95% CI) 2.07 (1.64-2.61) and 1.52 (1.08-2.14), respectively. Egger regression test did not demonstrate any significance for the publication bias. CONCLUSION G-CSF administration has a beneficial role on the clinical outcome after embryo transfer by both routes of local infusion and systematic administration, especially for the cases with RIF. Further RCTs are needed to investigate the role of G-CSF in thin endometrium patients.

Abstract
PURPOSE Artificial oocyte activation using calcium ionophores and enhancement of embryonic developmental potential by the granulocyte-macrophage colony-stimulating factor (GM-CSF) have already been reported. In this study, we evaluated the synergistic effect of these two methods on aged human unfertilized oocytes after intracytoplasmic sperm injection (ICSI). Then, we cultured the resulting embryos to the blastocyst stage and screened them for chromosomal abnormalities, to assess the safety of this protocol. METHODS Aged human oocytes deemed unfertilized after ICSI were activated, either by briefly applying the calcium ionophore A23187 alone (group A) or by briefly applying the ionophore and then supplementing the culture medium with recombinant human GM-CSF (rhGM-CSF) (group B). Next, the development was monitored in a time-lapse incubator system, and ploidy was analyzed by array comparative genomic hybridization (aCGH), after whole embryo biopsy and whole genome amplification. Differences between oocytes and resulting embryos in both groups were evaluated statistically. RESULTS Oocytes unfertilized after ICSI can be activated with the calcium ionophore A23187 to show two pronuclei and two polar bodies. Addition of rhGM-CSF in the culture medium of A23187-activated oocytes enhances their cleaving and blastulation potential and results in more euploid blastocysts compared to the culture medium alone. CONCLUSIONS This study shows that activating post-ICSI aged human unfertilized oocytes with a combination of a calcium ionophore and a cytokine can produce good-morphology euploid blastocysts.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is required for proliferation, differentiation, and survival of cells. It is also a biomarker of human oocyte developmental competence for embryo implantation. In humans, the G-CSF concentration peaks during the ovulatory phase of the ovarian cycle. In this study, the expressions of G-CSF and its receptor were analyzed by polymerase chain reaction in granulosa cells (GCs), CL, cumulus cells (CCs), and oocytes. Cumulus-oocyte complexes were aspirated from antral follicles of 1 to 3 mm (small follicles) and 4 to 6 mm (medium follicles). Cumulus-oocyte complexes from two kinds of follicles were matured in protein-free maturation medium supplemented with various concentrations of G-CSF (0, 10, and 100 ng/mL). By real-time polymerase chain reaction, the expressions of G-CSF and its receptor were detected in GCs, CL, CCs, and oocytes. Interestingly, the G-CSF transcript levels were significantly lower in oocytes than in the other cell types, whereas the G-CSF receptor transcript levels in oocytes were similar to those in GCs. After 44 hours of IVM, no differences in the rate of nuclear maturation were detected; however, the intracellular reactive oxygen species levels in oocytes from both groups of follicles matured with 10 ng/mL of human recombinant G-CSF (hrG-CSF) groups were significantly lower (P < 0.05). After parthenogenetic activation, the cleavage rates were significantly (P < 0.05) higher in 100 ng/mL hrG-CSF-treated small (63.3%) follicles than in 0, 10 ng/mL hrG-CSF-treated small (38.6% and 49.0%, respectively) follicles and 0 ng/mL hrG-CSF-treated medium (52.1%) follicles, and the cleavage rates were significantly (P < 0.05) higher in 10 ng/mL hrG-CSF-treated medium (76.3%) follicles than in all other groups. The blastocyst formation rates were significantly (P < 0.05) higher in 100 ng/mL hrG-CSF-treated small (31.2%) follicles than in 0 and 10 ng/mL hrG-CSF small (10.4% and 15.6%, respectively) follicles, and the 10 ng/mL hrG-CSF medium (45.7%) follicle was significantly (P < 0.05) higher than in all other groups. The total cell number in blastocysts from the 10 ng/mL hrG-CSF medium (106.5) follicles was significantly (P < 0.05) increased compared to 0, 10, 100 ng/mL hrG-CSF small (55.0, 73.7 and 59.5, respectively) follicles and 0, 100 ng/mL hrG-CSF-treated medium (82.5 and 93.5, respectively) follicles. After IVF, the blastocysts stage was significantly (P < 0.05) increased in 10 ng/mL hrG-CSF-treated medium (36.4%) follicles. Fertilization efficiency was significantly high in 100 ng/mL of small (29.1%) and 10 ng/mL of medium (44.0%) follicles. We also examined the Bcl2 and ERK2 transcript levels and found that they were significantly higher in the small and medium follicle treatment groups. In conclusion, these results indicate that hrG-CSF improve the viability of porcine embryos.

Abstract
BACKGROUND The advances in the world of IVF during the last decades have been rapid and impressive and culture media play a major role in this success. Until the 1980s fertility centers made their media in house. Nowadays, there are numerous commercially available culture media that contain various components including nutrients, vitamins and growth factors. This review goes through the past, present and future of IVF culture media and explores their composition and quality assessment. METHODS A computerized search was performed in PubMed regarding IVF culture media including results from 1929 until March 2014. Information was gathered from the websites of companies who market culture media, advertising material, instructions for use and certificates of analysis. The regulation regarding IVF media mainly in the European Union (EU) but also in non-European countries was explored. RESULTS The keyword 'IVF culture media' gave 923 results in PubMed and 'embryo culture media' 12 068 results dating from 1912 until March 2014, depicting the increased scientific activity in this field. The commercialization of IVF culture media has increased the standards bringing a great variety of options into clinical practice. However, it has led to reduced transparency and comparisons of brand names that do not facilitate the scientific dialogue. Furthermore, there is some evidence suggesting that suboptimal culture conditions could cause long-term reprogramming in the embryo as the periconception period is particularly susceptible to epigenetic alterations. IVF media are now classified as class III medical devices and only CE (Conformité Européene)-marked media should be used in the EU. CONCLUSION The CE marking of IVF culture media is a significant development in the field. However, the quality and efficiency of culture media should be monitored closely. Well-designed randomized controlled trials, large epidemiological studies and full transparency should be the next steps. Reliable, standardized models assessing multiple end-points and post-implantation development should replace the mouse embryo assay. Structured long-term follow-up of children conceived by assisted reproduction technologies and traceability are of paramount importance.

Abstract
BACKGROUND The objectives of the study were to characterize the expression of the α- and β-subunits of granulocyte-macrophage colony stimulating factor (GM-CSF) receptor in bovine cumulus cells and oocytes and to determine the effect of exogenous GM-CSF on cumulus cells expansion, oocyte maturation, IGF-2 transcript expression and subsequent competence for embryonic development. METHODS Cumulus-oocyte complexes (COC) were obtained by aspirating follicles 3- to 8-mm in diameter with an 18 G needle connected to a vacuum pump at -50 mmHg. Samples of cumulus cells and oocytes were used to detect GM- CSF receptor by immunofluorescence. A dose-response experiment was performed to estimate the effect of GM-CSF on cumulus cell expansion and nuclear/cytoplasmic maturation. Also, the effect of GM-CSF on IGF-2 expression was evaluated in oocytes and cumulus cells after in vitro maturation by Q-PCR. Finally, a batch of COC was randomly assigned to in vitro maturation media consisting of: 1) synthetic oviductal fluid (SOF, n = 212); 2) synthetic oviductal fluid supplemented with 100 ng/ml of GM-CSF (SOF + GM-CSF, n = 224) or 3) tissue culture medium (TCM 199, n = 216) and then subsequently in vitro fertilized and cultured for 9 days. RESULTS Immunoreactivity for both α and β GM-CSF receptors was localized in the cytoplasm of both cumulus cells and oocytes. Oocytes in vitro matured either with 10 or 100 ng/ml of GM-CSF presented a higher (P < 0.05) cumulus cells expansion than that of the control group (0 ng/ml of GM-CSF). GM-CSF did not affect the proportion of oocytes in metaphase II, cortical granules dispersion and IGF-2 expression. COC exposed to 100 ng/ml of GM-CSF during maturation did not display significant differences in terms of embryo cleavage rate (50.4% vs. 57.5%), blastocyst development at day 7 (31.9% vs. 28.7%) and at day 9 (17.4% vs. 17.9%) compared to untreated control (SOF alone, P = 0.2). CONCLUSIONS GM-CSF enhanced cumulus cell expansion of in vitro matured bovine COC. However, GM-CSF did not increase oocyte nuclear or cytoplasmic maturation rates, IGF-2 expression or subsequent embryonic development.

Abstract
BACKGROUND Previous experiments have shown that granulocyte colony-stimulating factor (G-CSF), quantified in the follicular fluid (FF) of individual oocytes, correlates with the potential for an ongoing pregnancy of the corresponding fertilized oocytes among selected transferred embryos. Here we present a proof of concept study aimed at evaluating the impact of including FF G-CSF quantification in the embryo transfer decisions. METHODS FF G-CSF was quantified with the Luminex XMap technology in 523 individual FF samples corresponding to 116 fresh transferred embryos, 275 frozen embryos and 131 destroyed embryos from 78 patients undergoing ICSI. RESULTS Follicular G-CSF was highly predictive of subsequent implantation. The receiving operator characteristics curve methodology showed its higher discriminatory power to predict ongoing pregnancy in multivariate logistic regression analysis for FF G-CSF compared with embryo morphology [0.77 (0.69–0.83), P < 0.001 versus 0.66 (0.58–0.73), P = 0.01)]. Embryos were classified by their FF G-CSF concentration: Class I over 30 pg/ml (a highest positive predictive value for implantation), Class II from 30 to 18.4 pg/ml and Class III <18.4 pg/ml (a highest negative predictive value). Embryos derived from Class I follicles had a significantly higher implantation rate (IR) than those from Class II and III follicles (36 versus 16.6 and 6%, P < 0.001). Embryos derived from Class I follicles with an optimal morphology reached an IR of 54%. Frozen-thawed embryos transfer derived from Class I follicles had an IR of 37% significantly higher than those from Class II and III follicles, respectively, of 8 and 5% (P < 0.001). Thirty-five per cent of the frozen embryos but also 10% of the destroyed embryos were derived from G-CSF Class I follicles. Non-optimal embryos appear to have been transferred in 28% (22/78) of the women, and their pregnancy rate was significantly lower than that of women who received at least one optimal embryo (18 versus 36%, P = 0.04). CONCLUSIONS Monitoring FF G-CSF for the selection of embryos with a better potential for pregnancy might improve the effectiveness of IVF by reducing the time and cost required for obtaining a pregnancy.

Abstract
The bovine corpus luteum (CL) is a unique, transient organ with well-coordinated mechanisms by which its development, maintenance, and regression are effectively controlled. Angiogenic factors, such as vascular endothelial growth factor A and basic fibroblast growth factor, play an essential role in promoting progesterone secretion, cell proliferation, and angiogenesis. These processes are critically regulated, through both angiogenic and immune systems, by the specific immune cells, including macrophages, eosinophils, and neutrophils, that are recruited into the developing CL. The bovine luteolytic cascade appears to be similar to that of general acute inflammation in terms of time-dependent infiltration by immune cells (neutrophils, macrophages, and T lymphocytes) and drastic changes in vascular tonus and blood flow, which are regulated by luteal nitric oxide and the vasoconstrictive factors endothelin-1 and angiotensin II. Over the period of maternal recognition of pregnancy, the maternal immune system should be well controlled to accept the semiallograft fetus. The information on the presence of the developing embryo in the genital tract is suggested to be transmitted to the ovary by both the endocrine system and the circulating immune cells. In the bovine CL, the lymphatic system, but not the blood vascular system, is reconstituted during early pregnancy, and interferon tau from the embryo could trigger this novel phenomenon. Collectively, the angiogenic and vasoactive factors produced by luteal cells and the time-dependently recruited immune cells within the CL and their interactions appear to play critical roles in regulating luteal functions throughout the life span of the CL.

Abstract
The disciplines of reproduction and immunology, once quite discrete, are now closely associated, with compelling evidence to suggest that immune mechanisms play important roles in the cervix, uterus, fallopian tubes and ovary. Cells and mediators classically described as part of the immune system are found throughout the reproductive tract. Disorders of reproduction, including pre-eclampsia, unexplained infertility, endometriosis, recurrent miscarriage and disturbed fetal growth almost certainly have some of their origins in the dysfunction of immune regulation. There appears to be some evidence that immune disorders, such as rheumatoid arthritis and scleroderma, can manifest as infertility, before clinical disease becomes apparent.

Abstract
BACKGROUND Expression and selective cellular localization of granulocyte-macrophage colony-stimulating factor (GM-CSF) and its receptor in ovarian tissue imply an autocrine/paracrine role in ovarian function. Evidence indicating a functional role for GM-CSF in ovarian follicular cell function has been provided by studies with GM-CSF knockout (GM-/-) mice, which suggest that GM-CSF influences events associated with murine follicular maturation. METHODS Immature female rats were treated with GM-CSF, FSH or saline for 5 or 10 days. Ovaries were collected for histologic examination and immunostaining determination of CYP17, a theca cell marker. In addition, ovarian section slides were evaluated by immunofluorescence for CD45, an ovarian leukocyte marker. To investigate the possible mechanism of GM-CSF action on follicular development, theca-interstitial cells (T-I) were separated and cultured. Cells were treated with increasing concentrations of GM-CSF, then evaluated for CYP17 mRNA and protein expression assays. RESULTS After 10 days of treatment with GM-CSF, the number of small preantral and large preantral follicles was significantly increased compared with the control group (P < 0.05). Similarly, treatment with FSH increased the number of small preantral and large preantral follicles (P < 0.05). CD45 expression measured by immunofluorescence was not different in the three groups, indicating that the distribution of leukocytes was unchanged. In addition, CYP17 was increased in the T-I cells both in vivo and in vitro after GM-CSF treatment. CONCLUSION The present results suggest that GM-CSF may play a significant role in follicular development.

Abstract
BACKGROUND We investigated granulocyte colony-stimulating factor (G-CSF) in human reproduction. METHODS From a total sample of 93 patients, we analysed in group 1 (n = 82) the level of G-CSF and estradiol (E(2)) in serum and follicular fluid (FF) on day of follicular puncture (FP). Furthermore, in response to ovarian stimulation, G-CSF levels in serum were compared between low (n = 11), moderate (n = 53) and high (n = 18) response patients. In group 2 (n = 23) serum for G-CSF assessment was collected throughout menstrual cycle until gestation. Group 3 (n = 11) patients with endometriosis were assessed for G-CSF in serum and FF on day of FP without further differentiation. RESULTS G-CSF in FF was higher than in serum (P < 0.01). G-CSF in serum increased from low through moderate to high response (P < 0.001); pregnancy rates were 0, 24.5 and 33.5% respectively. G-CSF in serum increased throughout stimulation, reached a peak with ovulation induction (P = 0.01) and decreased until embryo transfer (P=0.001). G-CSF level only in pregnant patients (n = 11) increased from embryo transfer to implantation to gestation (P = 0.005). In endometriosis patients G-CSF in serum and FF was lower than in non-endometriosis patients (P < or = 0.03) and corresponded with low response patients. CONCLUSIONS G-CSF is involved in follicle development and may be a predictor of IVF outcome.

Abstract
Magmas is a protein that is involved in GM-CSF signaling in a myeloid cell line. Its precise role in the signal transduction process is unclear. To accurately characterize Magmas expression in a variety of cells, mouse embryos and adult murine tissues were analyzed for both mRNA and protein content. Magmas expression was detected as early as the day 6.5 embryo. The level of expression was developmentally regulated. During embryogenesis, elevated Magmas was observed in several structures, including heart, liver, notochord, choroid plexus, cervical ganglion, and nasal mucosa. Muscle, pancreas, intestinal mucosa, and testes were among the adult tissues with high Magmas expression. Most cell types, including hepatocytes and skeletal, smooth, and cardiac myocytes, also expressed the GM-CSF receptor (GMR) but the relative tissue levels of GMR were not always proportional to Magmas. The expression patterns suggest that Magmas has a role in both developing and mature tissues.

Abstract
OBJECTIVE To study the influence of an LHRH (luteinizing hormone releasing hormone) antagonist protocol (Cetrorelix) and the use of recombinant follicle-stimulating hormone (FSH) on the development of leukocytosis, compared to the use of urinary HMG (human menopausal gonadotrophin). DESIGN Prospective, randomized phase III clinical trial. SETTING Infertility day clinic, Department of Gynecology and Obstetrics. PATIENTS Thirty patients undergoing IVF/intracytoplasmic sperm injection (ICSI) treatment following controlled ovarian stimulation using a multiple dose protocol and the LHRH antagonist Cetrorelix. MAIN OUTCOME MEASURE Differences in white blood cell (WBC) count before stimulation, during the follicular phase and in the midluteal phase. RESULTS Statistically significant increase in WBC count in the HMG group from the start of stimulation to the midluteal phase. No statistically significant increase in the recFSH group, but only a trend towards higher values was observed. CONCLUSION The development of a leukocytosis in controlled ovarian stimulation does not depend on the protocol used. Urinary gonadotrophins seem to have a greater potential to increase WBC count compared to recombinant gonadotrophins.

Abstract
During the estrous cycle and early pregnancy, lymphohemopoietic cytokines and chemokines contribute to the regulation of ovarian function by orchestrating the recruitment and activation of leukocytes associated with the ovulatory follicle and corpus luteum. The purpose of this study was to investigate the physiological role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in the ovary, utilizing mice genetically deficient in GM-CSF. Our results show that the mean duration of the estrous cycle in GM-CSF-deficient (GM-/-) mice was extended by 1.5 days (mean +/- SE, 4.9 +/- 0.3 vs. 6.5 +/- 0.5 days for GM+/+ and GM-/- mice, respectively). Similar ovulation rates were observed in immature superovulated mice (31.8 +/- 7.7 vs. 28.9 +/- 6.4 oocytes per mouse) and adult naturally cycling mice (10.4 +/- 0.8 vs. 10.3 +/- 0.8 oocytes per mouse). Furthermore, comparable numbers of oocytes were released from GM+/+ and GM-/- ovaries in an in vitro perfusion model. However, ovaries in pregnant GM-/- mice were found to comprise fewer cells and synthesize less progesterone (141.6 +/- 10.3 vs. 116.5 +/- 6 nM plasma), although the duration of pseudopregnancy was unaltered by GM-CSF deficiency (11.0 +/- 0.2 vs. 11.0 +/- 0.5 days). Immunohistochemical staining of leukocytes in the ovary during the periovulatory period indicated that the size and composition of ovarian leukocyte populations were unaltered in the absence of GM-CSF. However, an effect of GM-CSF deficiency on the activation phenotype of ovarian leukocytes was indicated by a 57% increase in mean secretion of nitric oxide in in vitro-perfused GM-/- ovaries, and diminished major histocompability complex (MHC) class II (Ia) expression in ovarian macrophages and/or dendritic cells (30.5 +/- 7. 2% vs. 9.1 +/- 1.8% positive stain in GM+/+ and GM-/- ovaries, respectively). Furthermore, ovarian macrophages and neutrophils were diminished in number after parturition, with significantly decreased CD11b+ (Mac-1) staining in the stromal region of postpartum GM-/- ovaries (6.7 +/- 0.6 vs. 3.6 +/- 0.7% positive stain). In summary, GM-CSF does not appear to be essential for ovarian function but may play a role in fine-tuning the activation status and adhesive properties of ovarian myeloid leukocytes. Aberrant activation of these cells appears to compromise the luteinization process and the steroidogenic capacity of the corpus luteum during early pregnancy in GM-CSF-deficient mice.

Abstract
On the basis of the finding of alternatively spliced mRNAs, the -subunit of the receptor for GM-CSF is thought to exist in both a membrane spanning (tmGMR) and a soluble form (solGMR). However, only limited data has been available to support that the solGMR protein product exists in vivo. We hypothesized that hematopoietic cells bearing tmGMR would have the potential to also produce solGMR. To test this hypothesis we examined media conditioned by candidate cells using functional, biochemical, and immunologic means. Three human leukemic cell lines that express tmGMR (HL60, U937, THP1) were shown to secrete GM-CSF binding activity and a solGMR-specific band by Western blot, whereas a tmGMR-negative cell line (K562) did not. By the same analyses, leukapheresis products collected for autologous and allogeneic stem cell transplants and media conditioned by freshly isolated human neutrophils also contained solGMR. The solGMR protein in vivo displayed the same dissociation constant (Kd = 2-5 nmol) as that of recombinant solGMR. A human solGMR ELISA was developed that confirmed the presence of solGMR in supernatant conditioned by the tmGMR-positive leukemic cell lines, hematopoietic progenitor cells, and neutrophils. Furthermore, the ELISA demonstrated a steady state level of solGMR in normal human plasma (36 ± 17 pmol) and provided data suggesting that plasma solGMR levels can be elevated in acute myeloid leukemias.

Abstract
PROBLEM To determine the temporal and spatial expression of granulocyte macrophage-colony stimulating factor (GM-CSF) and GM-CSF alpha and beta receptor mRNA and protein in human endometrium. METHOD OF STUDY The endometrial expression of GM-CSF and GM-CSF receptor mRNA and protein was determined using competitive quantitative reverse transcription polymerase chain reaction (Q-RT-PCR), in situ hybridization, and immunohistochemistry. RESULTS Endometrium expresses GM-CSF and GM-CSF alpha receptor mRNA with maximal expression occurring during the mid-secretory phase (21.1 +/- 4.2 and 32.2 +/- 7.7 x 10(6) mRNA copies/microg total RNA) compared to the proliferative phase (1.46 +/- 0.4 and 7.5 +/- 0.5 x 10(6) copies) of the menstrual cycle, with a significant reduction (0.67 +/- 0.1 and 1.7 +/- 0.2 x 10(6) mRNA copies) during the post-menopausal period (P < 0.05). The endometrium expresses a significantly lower level of GM-CSF beta receptor mRNA (approximately 0.01 x 10(5) mRNA copies). Endometrial luminal and glandular epithelial cells are the primary site of GM-CSF mRNA and protein expression, while arteriole endothelial, stromal, and inflammatory cells are the primary site of GM-CSF alpha receptor protein. GM-CSF beta receptor protein has a similar cellular distribution as GM-CSF. CONCLUSION Temporal and spatial expression of GM-CSF and GM-CSF receptors in human endometrium during the menstrual cycle suggests that epithelial-derived GM-CSF in an autocrine/paracrine manner may influence various endometrial biological activities, local inflammatory response, and macrophage survival.

Abstract
Spermatogenesis is initiated with the divisions of the type A spermatogonial stem cells; however, the regulation of this stem cell population remains unknown. In order to obtain a better understanding of the biology of these cells, type A spermatogonia were isolated from 80-day-old pig testes by sedimentation velocity at unit gravity. The cells were cultured for up to 120 h in Dulbecco's modified Eagle's medium/Ham's F-12 medium (DMEM/F12) or a potassium-rich medium derived by the simplex optimization method (KSOM). At the end of the 120-h culture period, 30-50% of the spermatogonia were viable in KSOM, whereas in DMEM/F12 very few cells survived. Using KSOM as the culture medium, the effects of stem cell factor (SCF) and granulocyte macrophage-colony stimulating factor (GM-CSF) were studied. SCF significantly enhanced the percentage of cell survival at 100 ng/ml but not at lower concentrations. In comparison, GM-CSF promoted survival at relatively low concentrations (0.01, 0.1, and 1 ng/ml). At a higher dose (10 ng/ml), a significant reduction in percentage of cell survival was observed. The combination of SCF with GM-CSF had no significant effect on the percentage survival of type A spermatogonial cells. These data indicate that SCF and GM-CSF play a role in the regulation of survival and/or proliferation of type A spermatogonia.

Abstract
We studied the presence and numbers of macrophages in the different compartments of the human menstrual corpus luteum (CL) in relation to the proliferative activity and apoptosis in luteal cells. Macrophages were recognized by immunohistochemical demonstration of the lysosome-associated glycoprotein CD68, and proliferating cells by immunohistochemical detection of the cell cycle-related protein Ki67 and by counting mitotic cells. In general, changes in the number of macrophages were parallel to the functional activity of the CL. Macrophage numbers increased up to the end of the early luteal phase, remained relatively unchanged during the midluteal phase, and decreased at the late luteal phase. Furthermore, macrophages showed prominent morphological changes during the cycle. They showed round or elongated cytoplasm during the early and late luteal phases, and dendritic features in the midluteal phase. Proliferating cells were very abundant on Days 15-16 and showed a significant decrease thereafter. Most proliferating cells corresponded to stromal (mainly vascular) cells. However, about 5% of granulosa-lutein cells and about 15% of theca-lutein cells were proliferating during the early and midluteal phases. Regression of the CL at the late luteal phase was associated with both a decrease in the number of proliferating cells and an increase in the number of apoptotic cells, which were highly increased on Days 25-27 of the cycle. The number of macrophages was not related to cell proliferation nor to cell death during the luteal phase. The observed changes in both macrophage number and morphology suggest the existence of a bidirectional communication between macrophages and steroidogenic cells in the human CL, or regulation of both cell populations by similar mechanisms.

Abstract
To obtain clues as to whether granulocyte-macrophage colony-stimulating factor (GM-CSF) is related to ovarian physiology, the sites, the gene expression and the production of GM-CSF in the ovary during follicular development and luteinization were studied in equine CG (eCG)-primed immature mice and rats. During follicular development, the expression of GM-CSF mRNA was localized in theca-interstitial tissues, oocytes and granulosa cells of small developing follicles in mice. In the mouse ovary after ovulation, luteal tissues as well as the above components had intense signals for GM-CSF mRNA. Mast cells, which were present mainly in the ovarian medulla, also expressed mRNA for GM-CSF in rats. Immunohistochemical analyses with two different antibodies against murine GM-CSF revealed that GM-CSF-like immunoreactivity was detectable mainly in theca-interstitial, luteal tissues, oocytes and mast cells. Intense GM-CSF positive cells in theca-interstitial and luteal tissues were stained with anti-CD11b antibody in mice. Messenger RNAs for GM-CSF receptor subunits were expressed in mast cells of the medulla and in luteal tissues in rat ovary. The levels of GM-CSF released into the culture media by rat ovarian dispersed cells 1-2 days after eCG treatment were higher than those before the treatment, although no significant change in the levels of ovarian GM-CSF mRNA was detected by reverse transcription-polymerase chain reaction analysis. The secretion of GM-CSF was also increased by treatment of the cells with immune stimulators such as phorbol ester, interleukin-1 and lipopolysaccharide. These data indicate that ovarian macrophages and mast cells in addition to theca-interstitial cells, synthesize and release GM-CSF during ovarian cycles, and that ovarian GM-CSF secreting capacity is enhanced during early stages of follicular development in rodents.

Abstract
Interleukin 3 (IL-3) promotes development of hematopoietic cells through activation of the IL-3 receptor (IL-3R) complex consisting of alpha and beta subunits. The alpha subunit binds IL-3 with low affinity and forms a high-affinity receptor with the common beta subunit (beta c). The beta c subunit does not bind any cytokine by itself but is involved in the formation of high-affinity functional receptors for IL-5 and GM-CSF. As the alpha subunits provide the specificity to cytokines and beta c plays a major role in signal transduction, IL-3, GM-CSF and IL-5 exhibit similar functions when they act on the same cells. Surprisingly, no apparent hematological defect other than a reduced number of eosinophils was found in knock-out mice lacking an entire function of IL-3, GM-CSF and IL-5; this indicates a remarkable functional overlap with other cytokine systems for hematopoiesis. Binding of the cytokines to the receptor induces activation of the JAK2 tyrosine kinase that associates with beta c and triggers the signaling events. The membrane proximal region of beta c is responsible for activation of JAK2 and STAT5, as well as for induction of c-myc. The signals induced by this region are required for cell-cycle progression and DNA synthesis. Activation of the Ras pathway requires the distal region of beta c and is involved in the suppression of apoptosis. Proliferation of hematopoietic cells requires signals for both DNA synthesis and anti-apoptosis. In this review, we describe the recent findings of the function and signal transduction mediated by the IL-3R system.
