Abstract
INTRODUCTION Suitable cryopreservation procedures of pre-pubertal testicular tissue associated with efficient culture conditions are crucial in the fields of fertility preservation and restoration. In vitro spermatogenesis remains a challenging technical procedure to undergo a complete spermatogenesis.The number of haploid cells and more specifically the spermatic yield produced in vitro in mice is still extremely low compared to age-matched in vivo controls and this procedure has never yet been successfully transferred to humans. METHODS To evaluate the impact of in vitro culture and freezing procedure, pre-pubertal testicular mice testes were directly cultured until day 4 (D4), D16 and D30 or cryopreserved by controlled slow freezing then cultured until D30. Testes composed of a panel of 6.5 dpp (days postpartum), 10.5 dpp, 22.5 dpp, and 36.5 dpp mice were used as in vivo controls. Testicular tissues were assessed by histological (HES) and immunofluorescence (stimulated by retinoic acid gene 8, STRA8) analyses. Moreover, a detailed transcriptome evaluation study has been carried out to study the gene expression patterns throughout the first in vitro spermatogenic wave. RESULTS Transcriptomic analyses reveal that cultured tissues expression profiles are almost comparable between D16 and D30; highlighting an abnormal kinetic throughout the second half of the first spermatogenesis during in vitro cultures. In addition, testicular explants have shown dysregulation of their transcriptomic profile compared to controls with genes related to inflammation response, insulin-like growth factor and genes involved in steroidogenesis. DISCUSSION The present work first shows that cryopreservation had very little impact on gene expression in testicular tissue, either directly after thawing or after 30 days in culture. Transcriptomic analysis of testis tissue samples is highly informative due to the large number of expressed genes and identified isoforms. This study provides a very valuable basis for future studies concerning in vitro spermatogenesis in mice.

Abstract
INTRODUCTION Cryopreservation of immature-testicular-tissue (ITT) prior to gonadotoxic treatment, while experimental, is the only recommended option for fertility preservation in prepubertal boys. The handling and manipulation of ITT prior to banking could influence the functionality, genetic and epigenetic integrity of cells. OBJECTIVES To investigate the impact of length of hypothermic holding of mouse ITT on the relative mRNA expression of the DNA methyltransferases (DNMTs) and global DNA methylation, post 14-days of organotypic culture. METHODS ITT from 6-day old mice were handled at hypothermic temperature (4 °C) for 6 and 24 h prior to 14-days organotypic culture. Relative mRNA expression of Dnmt1, Dnmt3a, and Dnmt3b along with global DNA methylation was measured from the cultured ITT. RESULTS No significant variation in the expression of Dnmt1, Dnmt3a, and Dnmt3b was observed in relation to varying holding time periods used. Further, global DNA methylation was comparable between 0, 6 and 24 h holding groups. CONCLUSIONS Short-term holding of ITT at 4 °C does not affect the DNA methylation process post organotypic culture. While fully acknowledging the limitations of this approach in the mouse model, the results we presented in this report will be of significant interest to the field.

Abstract
BACKGROUND Testicular tissue freezing is proposed for fertility preservation to (pre)pubertal boys with cancer before highly gonadotoxic treatment. Studies accurately comparing human (pre)pubertal testicular tissue quality before freezing and after thawing are exceptional. No study has reported this approach in a systematic manner and routine care. OBJECTIVES To assess the impact of a control slow freezing protocol on testicular tissue architecture and integrity of (pre)pubertal boys after thawing. MATERIALS AND METHODS (Pre)pubertal boys (n = 87) with cancer from 8 Reproductive Biology Laboratories of the French CECOS network benefited from testicular tissue freezing before hematopoietic stem cell transplantation. Seminiferous tubule cryodamage was determined histologically by scoring morphological alterations and by quantifying intratubular spermatogonia and the expression of DNA replication and repair marker in frozen-thawed testicular fragments. RESULTS A significant increase in nuclear and epithelial score alterations was observed after thawing (p < 0.0001). The global lesional score remained lower than 1.5 and comparable to fresh testicular tissue. The number of intratubular spermatogonia and the expression of DNA replication and repair marker in spermatogonia and Sertoli cells did not vary significantly after thawing. These data showed the good preservation of the seminiferous tubule integrity and architecture after thawing, as previously reported in our studies performed in prepubertal mice and rats. DISCUSSION The current study reports, for the first time, the development of a semi-quantitative analysis of cryodamage in human (pre)pubertal testicular tissue, using a rapid and useful tool that can be proposed in routine care to develop an internal and external quality control for testicular tissue freezing. This tool can also be used when changing one or several parameters of the freezing-thawing procedure. CONCLUSION Control slow freezing protocol without seeding maintains the seminiferous tubule architecture and integrity, the concentration of spermatogonia and the expression of DNA replication and repair marker in spermatogonia and Sertoli cells after thawing.

Abstract
Immunohistochemical analysis is a routine procedure for clinical and research studies in male fertility. However, most of the interpretations remain subjective and time-consuming, with inherent intra- and inter-observer variability. Given the prognostic and research implications of testicular assessment, a more objective and less time-consuming method is required. In the current study, we used in vitro matured pre-pubertal murine testes as a model. The main objective was to develop an affordable automated digital immunohistochemistry image analysis tool for an unbiased and quantitative assessment of testicular tissue sections. Testicular explants were fixed, cut, and stained for specific germ cell markers. The classical manual counting procedure was evaluated. Background and noise were reduced on brightfield images. Photomicrographs were stitched (Background_Elimination_Stitching) to create high-quality images. Two procedures were evaluated (IHC_Tool and Stained_Nuclear_Area); then a procedure (Necrotic_Area_Elimination) allowing withdrawal of the necrotic area observed after culture was assessed. Finally, the number of stained nuclei in the unaltered tissue area was extracted. The automated IHC_Tool procedure with images saved as TIFF at a ×200 magnification allowed the most rigorous cell quantification. IHC_Tool developed for testicular sample analysis can be used for various types of tissues. We foresee that this method will minimize inter-observer variations across laboratories and will be helpful for clinical trials and translational initiatives.

Abstract
Cryopreservation of testicular cells and tissues is useful for the preservation and restoration of fertility in pre-pubertal males expecting gonadotoxic treatment for cancer and genetic diseases causing impaired spermatogenesis. A number of freezing and vitrification protocols have thus been tried and variable results have been reported in terms of cell viability spermatogenesis progression and the production of fertile spermatozoa. A few studies have also reported the production of live offspring from cryopreserved testicular stem cells and tissues in rodents but their replication in large animals and human have been lacking. Advancement in in vitro spermatogenesis system has improved the possibility of producing fertile spermatozoa from the cryopreserved testis and has reduced the dependency on transplantation. This review provides an update on various cryopreservation strategies for fertility preservation in males expecting gonadotoxic treatment. It also discusses various methods of assessing and ameliorating cryoinjuries. Newer developments on in vitro spermatogenesis and testicular tissue engineering for in vitro sperm production from cryopreserved SSCs and testicular tissue are also discussed.

Abstract
Several lines of evidence strongly suggest that retinoic acid (RA) and stem cell factor (SCF)/c-Kit signal transduction pathways are involved in the differentiation of spermatogonial stem cells (SSCs). This study was aimed to investigate the effect of RA and SCF on in vitro differentiation of SSCs via evaluation of the mRNA expression of meiosis-specific genes in cultured testicular tissues. Testicular tissue samples were obtained from bilaterally vasectomized rats and also healthy adult rats and then were cultured for 25, 30, and 35 days on different conditions. The cultured testicular pieces were sectioned and stained with PAS to histological analysis. The total RNA was extracted from cultured testicular samples, and the expression of ACR, PRTM1, SYCP3, STRA8, c-KIT, PIWIL2, and OCT4 genes at mRNA level was quantified using real-time polymerase chain reaction (qPCR) procedure. After 1-month surgery, bilateral testicular weight showed a significant decrease in vasectomized adult rats compared with healthy adult rats (P < 0.05). Reduction in the diameter of the seminiferous tubules and depletion of advanced germinal elements in vasectomized rats compared with healthy adult rats were also observed. Our findings also demonstrated that the mRNA expression level of PRTM1, STRA8, c-KIT, PIWIL2, and OCT4 genes in cultured testicular tissues significantly up-regulated in experimental group II compared with the control group (P < 0.001). Our findings lead us to conclude that SCF improves in vitro differentiation of SSCs in the OA rats, at least partially, by transcriptionally upregulating PRTM1, STRA8, c-KIT, PIWIL2, and OCT4 genes.

Abstract
Testicular tissue freezing before gonadotoxic treatments allows the preservation of fertility for children suffering from cancer. Recently, the testis organ culture method was presented as a relevant method to restore the fertility of these patients. However, the yield of spermatozoa production is low in the mouse model and no gamete has been obtained in vitro in the rat model. Here, we assess different cryopreservation protocols and culture conditions to improve the efficiency of in vitro maturation of rat prepubertal testes. Testes from male rats aged 5 or 8 days post-partum were cultured onto agarose gels of different percentages. After determining the best culture conditions, different cryopreservation protocols were assessed. Finally, testicular tissues were cultured with media of various compositions and analyzed at different time points. Our results show that the cryopreservation protocols allow the preservation of tissue architecture, cell proliferation, with no or moderate increase of cell death. In vitro spermatogenesis did not proceed beyond the pachytene spermatocyte stage. Only 2 of the 6 tested media allowed the survival of differentiated germ cells over the 45-day culture period. In conclusion, this study highlights the necessity to further improve the organ culture method before applying it into the clinics.

Abstract
BACKGROUND Oncological procedures have irreversible side effects on germ cells for childhood cancer survival boys. In vitro culture of prepubertal testicular tissue has been proposed to restore fertility; however, recent data on animal models showed that meiotic and post-meiotic progression was impaired. OBJECTIVES As potential key inducers of the mitosis-meiosis switch, type 2 cannabinoid receptor (CB2 ) has been proposed to play a central role in the meiotic entry of male germ cells. Herein, the in vitro first spermatogenesis wave in mice was used to understand the impact of CB2 activation on the differentiation of spermatogonia until elongated spermatids. MATERIALS AND METHODS A first set of cultured testicular explants of 6.5 days post-partum (dpp) mice was performed to assess the impact of a range of JWH133 supplementation (10 nm, 100 nm, 1 µm, 10 µm). Then, the progressive development of germ cells at key timepoints of spermatogenesis was evaluated throughout (i) in vitro culture (day 2 [D2], D3, D6, D10, D18, and D30) coupled with (ii) in vivo counterparts (8.5, 9.5, 12.5, 16.5, 24.5, and 36.5 dpp). RESULTS CB2 was detected at the plasma membrane of cells, and a successful completion of spermatogenesis was obtained in vitro. One day after the activation of CB2 by 1 μm of the agonist JWH133, percentage of zygotene spermatocyte I increased. CONCLUSION After 30 days of culture, (i) an enrichment of haploid germ cells detected by flow cytometry, (ii) a reduced necrotic area, and (iii) an increase in the density of post-meiotic germ cells were observed. We showed that the activation of CB2 improves in vitro entry into meiosis and differentiation of spermatogonia, mimicking physiological meiotic transition.

Abstract
BACKGROUND In prepubertal boys with cancer, fertility preservation relies on testicular tissue freezing before treatment. In vitro maturation of frozen/thawed tissues could be one of the procedures envisaged to restore the fertility of cured patients. It is necessary to ascertain in the mouse model that in vitro-generated spermatozoa are able to ensure embryo development, without altering the epigenetic processes occurring during the pre-implantation period. OBJECTIVES The aims of the present study were to investigate the fertilizing ability of in vitro-produced spermatozoa and explore several epigenetic marks at different stages of embryo development. MATERIALS AND METHODS Fresh or controlled slow-frozen (CSF)/thawed testicular tissues from 6 to 7 days post-partum (dpp) mice were cultured for 30 days. Intracytoplasmic sperm injection (ICSI) experiments were performed using in vitro-produced spermatozoa. Testicular spermatozoa from 36 to 37 dpp mice were used as in vivo controls. DNA methylation/hydroxymethylation and histone post-translational modifications (H3K4me3, H3K27me3 and H3K9ac) were analysed by immunofluorescence from the zygote to the blastocyst stages. RESULTS The spermatozoa generated in cultures of fresh or CSF testicular tissues were able to initiate embryonic development. The freezing of prepubertal testicular tissues limits the production of spermatozoa in vitro and the fertilization rate after ICSI. Similar levels of H3K4me3, H3K27me3 and H3K9ac were found in ICSI embryos derived from in vitro- and in vivo-produced spermatozoa. DNA methylation levels were increased in 4-cell embryos and morula obtained by ICSI with in vitro-produced spermatozoa. DISCUSSION AND CONCLUSION Our study shows for the first time that the use of in vitro-produced spermatozoa alters DNA methylation/demethylation dynamics but has little impact on H3K4me3, H3K27me3 and H3K9ac levels in mouse early embryos. Further work will have to be performed to determine whether the use of these gametes is not deleterious for embryo development before considering a human application.

Abstract
Freezing-thawing procedures and in vitro culture conditions are considered as a source of stress associated with increased reactive oxygen species (ROS) generation, leading to a damaged cell aerobic metabolism and consequently to oxidative stress. In the present study, we sought to investigate whether vitamin E (Vit E) or reduced glutathione (GSH) enhances sperm production by decreasing ROS accumulation during in vitro maturation of prepubertal mice testes. Testes of prepubertal mice were cryopreserved using a freezing medium supplemented or not supplemented with Vit E and were cultured after thawing. In presence of Rol alone in culture medium, frozen-thawed (F-T) testicular tissues exhibited a higher ROS accumulation than fresh tissue during in vitro culture. However, Vit E supplementation in freezing, thawing, and culture media significantly decreased cytoplasmic ROS accumulation in F-T testicular tissue during in vitro maturation when compared with F-T testicular tissue cultured in the presence of Rol alone, whereas GSH supplementation in culture medium significantly increased ROS accumulation associated with cytolysis and tissue disintegration. Vit E but not GSH promoted a better in vitro sperm production and was a suitable ROS scavenger and effective molecule to improve the yield of in vitro spermatogenesis from F-T prepubertal mice testes. The prevention of oxidative stress in the cytoplasmic compartment should be regarded as a potential strategy for improving testicular tissue viability and functionality during the freeze-thaw procedure and in vitro maturation.

Abstract
RESEARCH QUESTION Do cryopreservation and in-vitro culture procedures affect the expression of DNA methyltransferases (DNMT) and histone-modifying enzymes, as well as the establishment of DNA methylation and histone post-translational modifications (PTM) in germ cells in prepubertal mouse testicular tissue? DESIGN This study investigated the expression of epigenetic modification enzymes, DNA methylation and histone PTM, and the spermatogenic progression after in-vitro maturation of fresh or cryopreserved mouse prepubertal testicular tissue. Fresh or cryopreserved testicular fragments from 6-7 days post-partum mice were cultured for 30 days in the presence of retinol with or without FSH. RESULTS The in-vitro maturation of fresh or cryopreserved tissue allowed the differentiation of spermatogonia into spermatozoa. Differences in the levels of transcripts encoding epigenetic modification enzymes (Dnmt1, Dnmt3a, Jarid1b, Src1, Sirt1, Hdac1) were found between 30-day tissue cultures and age-matched in-vivo controls. DNMT1/DNMT3a expression and the presence of 5-methylcytosine (5mC) were detected in spermatogonia and leptotene/zygotene spermatocytes in cultures. The relative 5mC fluorescence intensity was similar in spermatozoa produced in cultures of cryopreserved tissues or in vivo. H3K4me3, H3K9ac and H4K8ac were present in all germ cell types but differences in the proportion of germ cells containing these epigenetic marks were found after cultures. CONCLUSIONS Despite differences with the in-vivo situation, DNA methylation and histone methylation and acetylation occur in the mouse germline in in-vitro matured fresh or cryopreserved mouse prepubertal testicular tissue, and the expression of the enzymes catalysing these epigenetic modifications are maintained in vitro.

Abstract
STUDY QUESTION Can the spatio-temporal formation of an intact blood-testis barrier (BTB), which is essential for the progression of spermatogenesis, be reproduced in cultures of fresh or frozen/thawed prepubertal mouse testes? SUMMARY ANSWER Organotypic cultures allow the establishment and maintenance of major BTB components and the formation of a functional BTB in mouse testicular tissues. WHAT IS KNOWN ALREADY In vitro maturation of prepubertal testicular tissues is a promising approach to restore fertility in adult survivors of childhood cancer. Although gametes can be successfully obtained from prepubertal mouse testes in organotypic cultures, the spermatogenic yield remains low compared to in vivo controls. STUDY DESIGN, SIZE, DURATION Mouse testicular tissues were frozen using controlled slow freezing (CSF) or solid surface vitrification (SSV) procedures. A total of 158 testes (fresh n = 58, CSF n = 58 or SSV n = 42) from 6 to 7 days postpartum (dpp) mice were cultured at 34°C in basal medium (α-MEM, 10% KnockOut Serum Replacement, 5 μg/ml gentamicin) at a gas-liquid interphase (under 20% O2), with or without 10-6 M retinol, for 9, 16 and 30 days. In addition, 32 testes from 6-7, 15-16, 22-23 and 36-37 dpp mice were used as in vivo controls. PARTICIPANTS/MATERIALS, SETTING, METHODS The mRNA levels of BTB genes (Claudin 3, Claudin 11, Zonula occludens 1 and Connexin-43), germ cell-specific genes (Sal-like protein 4, Kit oncogene, Stimulated by retinoic acid gene 8, Synaptonemal complex protein 3, Transition protein 1 and Protamine 2), markers of Sertoli cell immaturity/maturity (anti-Mullerian hormone, androgen receptor, cyclin-dependent kinase inhibitor 1b) and the androgen-regulated gene Reproductive homeobox 5 (Rhox5) were measured by quantitative RT-PCR (RT-qPCR). The localization of BTB proteins in seminiferous tubules was studied by immunohistochemistry and spermatogenic progression was evaluated histologically. The integrity of the BTB was assessed using a biotin tracer. MAIN RESULTS AND THE ROLE OF CHANCE Modest differences in Claudin 11 (Cldn11), Zonula occludens 1 (Zo-1), Connexin-43 (Cx43) transcript levels and in the localization of the corresponding proteins were found between in vitro cultures of fresh or frozen/thawed testes and in vivo controls (P < 0.05). However, a 32-77-fold decrease in Claudin 3 (Cldn3) mRNA levels and a lack of CLDN3 immunolabelling in 36-44% of seminiferous tubules were observed in 30-day organotypic cultures (P < 0.05). Although Sertoli cell maturation and the completion of a full spermatogenic cycle were achieved after 30 days of culture, meiotic and postmeiotic progression was altered in cultured testicular tissues (P < 0.05). Moreover, an increased BTB permeability and a decreased expression of Rhox5 were observed at the end of the culture period in comparison with in vivo controls (P < 0.05). Completion of spermatogenesis occurred in vitro in seminiferous tubules with an intact BTB, and in those expressing or lacking CLDN3. LARGE SCALE DATA None. LIMITATIONS, REASONS FOR CAUTION Further studies will be needed to determine whether the expression of other BTB components is altered and to decipher the reason for lower Cldn3 and Rhox5 mRNA levels in organotypic cultures. WIDER IMPLICATIONS OF THE FINDINGS This work contributes to a better understanding of the molecular mechanisms occurring in in vitro matured prepubertal testes. The organotypic culture system will have to be developed further and optimized for human tissue, before potential clinical applications can be envisaged.

Abstract
STUDY QUESTION Does vitamin A (retinol, Rol) prevent round spermatid nuclear damage and increase the production of motile sperm during in vitro maturation of vitrified pre-pubertal mouse testicular tissue? SUMMARY ANSWER The supplementation of an in vitro culture of ~0.75 mm3 testicular explants from pre-pubertal mice with Rol enhances spermatogenesis progression during the first spermatogenic wave. WHAT IS KNOWN ALREADY The production of functional spermatozoa in vitro has only been achieved in the mouse model and remains a rare event. Establishing an efficient culture medium for vitrified pre-pubertal testicular tissue is now a crucial step to improve the spermatic yield obtained in vitro. The role of Rol in promoting the differentiation of spermatogonia and their entry into meiosis is well established; however, it has been postulated that Rol is also required to support their full development into elongated spermatids. STUDY DESIGN, SIZE, DURATION A total of 60 testes from 6.5 days post-partum (dpp) mice were vitrified/warmed, cut into fragments and cultured for 30 days: 20 testes were used for light microscopy and histological analyses, 20 testes for DNA fragmentation assessment in round spermatids and 20 testes for induced sperm motility assessment. Overall, 16 testes of 6.5 dpp were used as in vitro fresh tissue controls and 12 testes of 36.5 dpp mice as in vivo controls. Testes were vitrified with the optimal solid surface vitrification procedure and cultured with an in vitro organ culture system until Day 30 (D30). Histological analysis, cell death, degenerating round spermatids, DNA fragmentation in round spermatids and induced sperm motility were assessed. Testosterone levels were measured in media throughout the culture by radioimmunoassay. MAIN RESULTS AND THE ROLE OF CHANCE At D30, better tissue development together with higher differentiation of spermatogonial stem cells, and higher global cell division ability were observed for vitrified/warmed testicular fragments of ~0.75 mm3 with a culture medium supplemented with Rol compared to controls. During in vitro culture of vitrified pre-pubertal testicular tissue, Rol enhanced and maintained the entry of spermatogonia into meiosis and promoted a higher spermatic yield. Furthermore, decreased round spermatid nuclear alterations and DNA damage combined with induced sperm motility comparable to in vivo highlight the crucial role of Rol in the progression of spermatogenesis during the first wave. LIMITATIONS, REASONS FOR CAUTION Despite our promising results, the culture media will have to be further improved and adapted within the context of a human application. WIDER IMPLICATIONS OF THE FINDINGS The results have potential implications for the handling of human pre-pubertal testicular tissues cryopreserved for fertility preservation. However, because some alterations in round spermatids persist after in vitro culture with Rol, the procedure needs to be optimized before human application, bearing in mind that the murine and human spermatogenic processes differ in many respects. LARGE SCALE DATA None. STUDY FUNDING AND COMPETING INTERESTS This study was supported by a Ph.D. grant from the Normandy University and a financial support from 'la Ligue nationale contre le cancer' (both awarded to L.D.), funding from Rouen University Hospital, Institute for Research and Innovation in Biomedicine (IRIB) and Agence de la Biomédecine.

Abstract
BACKGROUND Germ cell depletion caused by chemical or physical toxicity, disease or genetic predisposition can occur at any age. Although semen cryopreservation is the first reflex for preserving male fertility, this cannot help out prepubertal boys. Yet, these boys do have spermatogonial stem cells (SSCs) that able to produce sperm at the start of puberty, which allows them to safeguard their fertility through testicular tissue (TT) cryopreservation. SSC transplantation (SSCT), TT grafting and recent advances in in vitro spermatogenesis have opened new possibilities to restore fertility in humans. However, these techniques are still at a research stage and their efficiency depends on the amount of SSCs available for fertility restoration. Therefore, maintaining the number of SSCs is a critical step in human fertility preservation. Standardizing a successful cryopreservation method for TT and testicular cell suspensions (TCSs) is most important before any clinical application of fertility restoration could be successful. OBJECTIVE AND RATIONALE This review gives an overview of existing cryopreservation protocols used in different animal models and humans. Cell recovery, cell viability, tissue integrity and functional assays are taken into account. Additionally, biosafety and current perspectives in male fertility preservation are discussed. SEARCH METHODS An extensive PubMED and MEDline database search was conducted. Relevant studies linked to the topic were identified by the search terms: cryopreservation, male fertility preservation, (immature)testicular tissue, testicular cell suspension, spermatogonial stem cell, gonadotoxicity, radiotherapy and chemotherapy. OUTCOMES The feasibility of fertility restoration techniques using frozen-thawed TT and TCS has been proven in animal models. Efficient protocols for cryopreserving human TT exist and are currently applied in the clinic. For TCSs, the highest post-thaw viability reported after vitrification is 55.6 ± 23.8%. Yet, functional proof of fertility restoration in the human is lacking. In addition, few to no data are available on the safety aspects inherent to offspring generation with gametes derived from frozen-thawed TT or TCSs. Moreover, clarification is needed on whether it is better to cryopreserve TT or TCS. WIDER IMPLICATIONS Fertility restoration techniques are very promising and expected to be implemented in the clinic in the near future. However, inter-center variability needs to be overcome and the gametes produced for reproduction purposes need to be subjected to safety studies. With the perspective of a future clinical application, there is a dire need to optimize and standardize cryopreservation and safety testing before using frozen-thawed TT of TCSs for fertility restoration.

Abstract
STUDY QUESTION Do the organ culture conditions, previously defined for in vitro murine male germ cell differentiation, also result in differentiation of rat spermatogonia into post-meiotic germ cells exhibiting specific markers for haploid germ cells? SUMMARY ANSWER We demonstrated the differentiation of rat spermatogonia into post-meiotic cells in vitro, with emphasis on exhibiting, protein markers described for round spermatids. WHAT IS KNOWN ALREADY Full spermatogenesis in vitro from immature germ cells using an organ culture technique in mice was first reported 5 years ago. However, no studies reporting the differentiation of rat spermatogonia into post-meiotic germ cells exhibiting the characteristic protein expression profile or into functional sperm have been reported. STUDY DESIGN, SAMPLES/MATERIALS, METHODS Organ culture of testicular fragments of 5 days postpartum (dpp) neonatal rats was performed for up to 52 days. Evaluation of microscopic morphology, testosterone levels, mRNA and protein expression as measured by RT-qPCR and immunostaining were conducted to monitor germ cell differentiation in vitro. Potential effects of melatonin, Glutamax® medium, retinoic acid and the presence of epidydimal fat tissue on the spermatogenic process were evaluated. A minimum of three biological replicates were performed for all experiments presented in this study. One-way ANOVA, ANOVA on ranks and student's t-test were applied to perform the statistical analysis. MAIN RESULTS AND THE ROLE OF CHANCE Male germ cells, present in testicular tissue pieces grown from 5 dpp rats, exhibited positive protein expression for Acrosin and Crem (cAMP (cyclic adenosine mono phosphate) response element modulator) after 52 days of culture in vitro. Intra-testicular testosterone production could be observed after 3 days of culture, while when epididymal fat tissue was added, spontaneous contractility of cultured seminiferous tubules could be observed after 21 days. However, no supportive effect of the supplementation with any factor or the co-culturing with epididymal fat tissue on germ cell differentiation in vitro or testosterone production was observed. LIMITATIONS, REASONS FOR CAUTION The human testis is very different in physiology from the rat testis, further investigations are still needed to optimize the organ culture system for future use in humans. WIDER IMPLICATIONS OF THE FINDINGS The successful differentiation of undifferentiated spermatogonia using the testis explant culture system might be employed in future to produce sperm from human spermatogonia as a clinical tool for fertility preservation in boys and men suffering infertility.
