Abstract
Mouse testicular tissue is composed of seminiferous tubules and interstitial tissue. Mammalian spermatogenesis is divided into three stages: spermatocytogenesis (mitotic divisions) in which spermatogonial stem cells (SSCs) turn into spermatocytes, followed by two consecutive meiotic divisions in which spermatocytes form spermatids. Spermatids differentiate into spermatozoa during spermiogenesis. Various factors affect the process of spermatogenesis and the organization of cells in the testis. Any disorder in different stages of spermatogenesis will have negative effects on male fertility. The aim of the current study was to compare the in vitro and in vivo spermatogenesis processes before and after transplantation to azoospermic mice using ultrastructural techniques. In this study, mice were irradiated with single doses of 14 Gy 60Co radiation. SSCs isolated from neonatal mice were cultured in vitro for 1 week and were injected into the seminiferous tubule recipient's mice. Testicular cells of neonatal mice were cultured in the four groups on extracellular matrix-based 3D printing scaffolds. The transplanted testes (8 weeks after transplantation) and cultured testicular cells in vitro (after 3 weeks) were then processed for transmission electron microscopy studies. Our study's findings revealed that the morphology and ultrastructure of testicular cells after transplantation and in vitro culture are similar to those of in vivo spermatogenesis, indicating that spermatogenic cell nature is unaltered in vitro.

Abstract
Pluripotent stem cells (PSCs) are widely recognized as one of the most promising types of stem cells for applications in regenerative medicine, tissue engineering, disease modeling, and drug screening. This is due to their unique ability to differentiate into cells from all three germ layers and their capacity for indefinite self-renewal. Initially, PSCs were cultured using animal feeder cells, but these systems presented several limitations, particularly in terms of Good Manufacturing Practices (GMP) regulations. As a result, feeder-free systems were introduced as a safer alternative. However, the precise mechanisms by which feeder cells support pluripotency are not fully understood. More importantly, it has been observed that some aspects of the need for feeder cells like the optimal density and cell type can vary depending on conditions such as the developmental stage of the PSCs, phases of the culture protocol, the method used in culture for induction of pluripotency, and intrinsic variability of PSCs. Thus, gaining a better understanding of the divergent roles and necessity of feeder cells in various conditions would lead to the development of condition-specific defined feeder-free systems that resolve the failure of current feeder-free systems in some conditions. Therefore, this review aims to explore considerable feeder-related issues that can lead to the development of condition-specific feeder-free systems.

Abstract
For patients who had testicular tissue cryopreserved before receiving gonadotoxic therapies, transplantation of testicular tissues and cells has been recommended as a potential therapeutic option. There are no studies that indicate the generation of sperm after human immature testicular tissue (ITT) or spermatogonial stem cells (SSCs) transplantation. The use of releasing scaffolds and localized drug delivery systems as well as the optimizing transplantation site can play an effective role in increasing the efficiency and improving the quality of testicular tissue and cell transplantation in animal models. Current research is focused on optimizing ITT and cell transplantation, the use of releasing scaffolds, and the selection of the right transplantation site that might restore sperm production or male infertility treatment. By searching the PubMed and Google Scholar databases, original and review papers were collected. Search terms were relevant for SSCs and tissue transplantation. In this review, we'll focus on the potential advantages of using scaffolds and choosing the right transplantation site to improve transplantation outcomes.

Abstract
<strong>Objective: </strong>Epigenetic and genetic changes have important roles in stem cell achievements. Accordingly, the aim of this<br />study is the evaluation of the epigenetic and genetic alterations of different culture systems, considering their efficacy in<br />propagating human spermatogonial stem cells isolated by magnetic-activated cell sorting (MACS).<br /><strong>Materials and Methods:</strong> In this experimental study, obstructive azoospermia (OA) patient-derived spermatogonial cells were divided into two groups. The MACS enriched and non-enriched spermatogonial stem cells (SSCs) were cultured in the control and treated groups; co-culture of SSCs with Sertoli cells of men with OA, co-culture of SSCs with healthy Sertoli cells of fertile men, the culture of SSCs on PLA nanofiber and culture of testicular cell suspension. Gene-specific methylation by MSP, expression of pluripotency (NANOG, C-MYC and OCT-4), and germ cells specific genes (Integrin α6, Integrin β1, PLZF) evaluated. Cultured SSCs from the optimized group were transplanted into the recipient azoospermic mouse.<br /><strong>Results:</strong> The use of MACS for the purification of human stem cells was effective at about 69% with the culture of the testicular suspension, being the best culture system. Upon purification, the germ-specific gene expression was significantly higher in testicular cell suspension and treated groups (P≤0.05). During the culture time, gene-specific methylation patterns of the examined genes did not show any changes. Our data from transplantation indicated the homing of the donor-derived cells and the presence of human functional sperm.<br /><strong>Conclusion:</strong> Our in vivo and in vitro results confirmed that culture of testicular cell suspension and selection of<br />spermatogonial cells could be effective ways for purification and enrichment of the functional human spermatogonial cells. The epigenetic patterns showed that the specific methylation of the evaluated genes at this stage remained constant with no alteration throughout the entire culture systems over time.

Abstract
Abstract
Study question
Does re-vitrification affect on methylation level of H19/IGF2 DMR differentially methylated region(DMR) in human in vitro-produced blastocysts?
Summary answer
The results of this study showed that re-vitrification had no significant effect on the methylation level of H19 / IGF2 DMR region in human blastocysts.
What is known already
Nowadays, re-vitrification seems to be a successful and useful method to prevent the discarding of extra embryos. Several reports have indicated that the embryo manipulations during ART may result in epigenetic errors. This has been attributed to the concurrency of the ART manipulations and epigenetic events after fertilization. The effect of embryo re-vitrification on epigenetic changes has not been studied so far. The aim of this study is to evaluate the effect of embryo re-vitrification on methylation level of H19/IGF2 differentially methylated region (DMR) in donated human blastocysts.
Study design, size, duration
The effect of re-vitrification on methylation level of H19/IGF2 DMR was evaluated in 9 ICSI-derived human embryos individually and the expressions of H19 and IGF2 were assessed in 15 embryos individually. Embryos were donated from fertile couples referring for family balancing program. Donated embryos were cultured to blastocyst stage and high quality blastocyst (AA-AB) assigned to three groups: fresh, vitrified and re-vitrification. Scoring of blastocysts were according to Gardner et al. (2012) grading system.
Participants/materials, setting, methods
Collected blastocysts were vitrified on Cryotech carriers, with the method described by Kuwayama. After warming of blastocysts and 4-5 hours culturing of them, expression of H19 and IGF2 genes in blastocysts evaluated with Real time PCR and methylation levels of H19/IGF2 DMR in blastocysts were analyzed by Bisulfite Sequencing PCR (BSP) technique. 10 clones were sequenced per replicate. Methylation status of lymphocyte was used as control to verify the credibility of our analysis system.
Main results and the role of chance
The results showed that the overall percentage of methylated CpGs of H19/IGF2 DMR in the control, vitrification, re-vitrification groups and lymphocyte were 42.71, 40.90, 39.23% and 49.30 %. respectively. There was no significant difference in methylation level of H19/IGF2 DMR between the groups. H19 and IGF2 expression did not show a significant difference in vitrified group compared to the control and in re-vitrified group compared to vitrified.
Limitations, reasons for caution
- Small number of samples examined due to difficult access to human blastocysts donated by fertile couples.
- Evaluation of high-quality embryos donated by healthy fertile couples while embryos of infertile couples may respond differently.
Wider implications of the findings
According to the obtained results, embryo re-vitrification did not have a significant change on the methylation level of H19/IGF2 DMR and expression of H19 and IGF2 genes. However, that further studies on the effect of re-vitrification on epigenetic errors in low-quality embryos and the embryos of infertile couples are needed.

Abstract
Objective Sperm cryopreservation results in damage to membrane integrity, sperm viability, sperm motility, and DNA structure. We aimed to evaluate the effect of plasma rich in growth factors (PRGF) on sperm parameters during the freeze-thaw process. Materials and Methods In the first phase of this prospective study, after sperm preparation, 10 normozoospermic specimens were cryopreserved by rapid freezing with different concentrations of PRGF including 0, 1, 5, and 10% to find the optimum dose. Sperm motility and viability were assessed in this phase. In the second phase of the study, based on the results of first phase, 25 normal sperm samples were frozen with 1% PRGF. All sperm parameters including motility, viability, acrosome reaction, and DNA integrity were assessed before freezing and after thawing. Results The rates of progressive and total sperm motility and viability were significantly higher in 1% PRGF compared to control, 5%, and 10% PRGF in the first phase (P<0.05). Supplementation of freezing medium with 1% PRGF could significantly improve all sperm parameters including sperm motility, viability, normal morphology, acrosome integrity, chromatin structure, chromatin integrity, DNA denaturation, and DNA fragmentation in comparison with the control group. Conclusion It appears that the supplementation of freezing medium with 1% PRGF could protect human sperm parameters during cryopreservation.

Abstract
Objective It was in the early 20th century when the quest for in vitro spermatogenesis started. In vitro spermatogenesis is critical for male cancer patients undergoing gonadotoxic treatment. Dynamic culture system creates in vivo-like conditions. In this study, it was intended to evaluate the progression of spermatogenesis after testicular tissue culture in mini-perfusion bioreactor. Materials and Methods In this experimental study, 12 six-day postpartum neonatal mouse testes were removed and fragmented, placed on an agarose gel in parallel to bioreactor culture, and incubated for 8 weeks. Histological, molecular and immunohistochemical evaluations were carried out after 8 weeks. Results Histological analysis suggested successful maintenance of spermatogenesis in tissues grown in the bioreactor but not on agarose gel, possibly because the central region did not receive sufficient oxygen and nutrients, which led to necrotic or degenerative changes. Molecular analysis indicated that Plzf, Tekt1 and Tnp1 were expressed and that their expression did not differ significantly between the bioreactor and agarose gel. Immunohistochemical evaluation of testis fragments showed that PLZF, SCP3 and ACRBP proteins were expressed in spermatogonial cells, spermatocytes and spermatozoa. PLZF expression after 8 weeks was significantly lower (P<0.05) in tissues incubated on agarose gel than in the bioreactor, but there was no significant difference between SCP3 and ACRBP expression among the bioreactor and agarose gel culture systems. Conclusion This three-dimensional (3D) dynamic culture system can provide somewhat similar conditions to the physiological environment of the testis. Our findings suggest that the perfusion bioreactor supports induction of spermatogenesis for generation of haploid cells. Further studies will be needed to address the fertility of the sperm generated in the bioreactor system..

Abstract
Background Preimplantation genetic diagnosis (PGD) has been developed to detect genetic disorders before pregnancy which is usually done on blastomeres biopsied from 8-cell stage embryos obtained from in vitro fertilization method (IVF). Here we report molecular PGD results for diagnosing of beta thalassemia (beta-thal) which are usually accompanied with evaluating chromosomal aneuploidies, HLA typing and sex selection. Methods In this study, haplotype analysis was performed using short tandem repeats (STRs) in a multiplex nested PCR and the causative mutation was detected by Sanger sequencing. Results We have performed PGDs on 350 blastomeres from 55 carrier couples; 142 blastomeres for beta-thal only, 75 for beta-thal and HLA typing, 76 for beta-thal in combination with sex selection, and 57 for beta-thal and aneuploidy screening. 150 blastomeres were transferable, 15 pregnancies were happened, and 11 babies born. We used 6 markers for beta-thal, 36 for aneuploidy screening, 32 for sex selection, and 35 for HLA typing. To our knowledge combining all these markers together and the number of STR markers are much more than any other studies which have ever done. Conclusions PGD is a powerful diagnostic tool for carrier couples who desire to have a healthy child and wish to avoid medical abortion.

Abstract
In newly improved MACS-Up method, magnetic field has been applied to separate non-apoptotic spermatozoa directly from the neat semen. The spermatozoa during passing through a viscous layer, located on the neat semen, contacted with progesterone and induced for the capacitation. Then, a clean population of non-apoptotic, and capacitated spermatozoa were selected in the pure culture media. Selected spermatozoa may be useful for use in ART. The 80 semen samples from normozoospermic individuals were divided separately into 4 attempts. Semen analysis, SCSA (sperm chromatin structure assay), FLICA (fluorescein-labelled inhibitors of caspase) methods, immunoassay of phosphorylation of tyrosine residues of sperm proteins, nuclear DNA integrity, caspase 3 activity and sperm capacitation rate were all performed for evaluation of sperm parameters respectively. To examine all aspects, the MACS-Up method compared with DGC (density gradient centrifuging) and MACS-DGC methods separately. This method can isolate non-apoptotic spermatozoa directly from the neat semen, which has similar performance compared to the MACS-DGC method. Movement and passing spermatozoa through the viscous layer, and contact with progesterone, significantly induced spermatozoa for capacitation compared with the control group. Also, the MACS-Up in comparison with routine DGC method could select spermatozoa with significantly higher total and progressive motility, DNA integrity, induced sperm population for capacitation and normal morphology. MACS-Up can be developed as an effective, short-time, and ease of performing method and used practically to select functional spermatozoa as novel sperm selection procedure. However, for clinical use of MACS-Up, all clinical aspects of this method should be considered and evaluated.

Abstract
Objectives In testis, the extracellular matrix (ECM) in addition to the supportive role for cells in the seminiferous epithelium, is also essential for the accurate functioning of these cells. Thus, using a decellularized testicular ECM (DTECM), as a scaffold for three-dimensional (3D) culture of testicular cells can mimic native ECM for studying in vitro spermatogenesis. Materials and Methods The rat testis was decellularized via perfusion of 0.5% sodium dodecyl sulfate (SDS) for 48 hr, followed by 1% Triton X-100 for 6 hr, and then 1% DNase I for 1 hr. The efficiency of decellularization was evaluated by histology, immunohistochemistry (IHC), scanning electron microscopy (SEM), and MTT test. The prepared scaffolds were recellularized with testicular cells and cultured and assessed with hematoxylin-eosin (H&E) staining after two weeks. Results Based on the H&E image, no trace of cell components could be observed in DTECM. IHC images demonstrated collagen types I and IV, laminin, and fibronectin were preserved. Masson's trichrome and alcian blue staining revealed that collagen and glycosaminoglycans (GAGs) were retained, and the SEM image indicated that 3D testicular architecture remained after the decellularization process. Based on the results of the MTT test, DTECM was cytocompatible, and H&E images represented that DTECM supports testicular cell arrangements in seminiferous tubule-like structures (STLSs) and organoid-like structures (OLSs). Conclusion The results showed that the applied protocol successfully decellularized the testis tissue of the rat. Therefore, these scaffolds may provide an appropriate vehicle for in vitro reconstruction of the seminiferous tubule.

Abstract
Embryo cryopreservation is a widely used technique in infertility management and today is an essential part of assisted reproductive technology (ART). In some cases, re-vitrification can be applied to good quality supernumerary warmed embryos that have not been transferred in the present cycle. However, there is no study about re-vitrification impact on microRNA and gene expression in human embryos. The purpose of this study is to evaluate miR-16, miR-let7a and target genes expression in in vitro produced human blastocysts following re-vitrification.Day3 embryos obtained from ICSI cycles of fertile couples referring for family balancing program were biopsied and cultured individually. On the fourth day (post-ICSI) male ones (choices of their parents) were transferred and the females (good quality embryos) were donated for research. Donated embryos were cultured to blastocyst stage and assigned to three groups: fresh, vitrified and re-vitrification. Embryos were vitrified on Cryotech carriers. Then blastocysts of three groups were individually assessed for expression of miR-16, miR-let7a and target genes.The results showed that re-vitrification of human blastocysts did not affect the ability to re-expand in culture. In addition, significant decrease was observed in miR-16 and miR-let7a expression in re-vitrified group compared to fresh (p < 0.05). A significant upregulation of the target genes ITGβ3 and BCL-2 in re-vitrified and vitrified embryos was observed compared to the fresh group (p < 0.05). The expression of BAX as a pro-apoptotic gene showed a significant decrease in re-vitrification group comparing with the fresh one (P < 0.05).The results of this research indicated that re-vitrification of embryos changes the expression of miR-16, miR-let-7a and their target genes. These alterations include increased expression of BCl-2 and ITGβ3 genes which play important roles in embryo survival and implantation, respectively. Clinical proof of these effects requires further research.

Abstract
Aquaporins play a crucial in transportation of water and solutes across cell membranes but their roles in male fertility are controversial. This study aimed to determine association of the expression level of aquaporin-3 (AQP3) and caspase-3 (CASP3) activity with sperm motility in asthenozoospermic individuals. Thirty-five asthenozoospermic and 35 normozoospermic individuals, participated in this study. Sperm chromatin structure assay (SCSA) for estimating of the DNA-damaged spermatozoa and Fluorescein-labelled inhibitors of caspases for assessment of active CASP3 were used by flow cytometry. Gene and protein expressions of AQP3 and CASP3 were assessed by real-time PCR and flow cytometry respectively. The AQP3 gene expression level in asthenozoospermic individuals was significantly lower than that of normozoospermic group whereas it was higher for the CASP3 gene expression (p < .01). The SCSA data in asthenozoospermic was significantly higher than that of normozoospermic group (p < .01). There was a negative and significant correlation between attenuated AQP3 protein level with activated CASP3 and SCSA in the asthenozoospermic group. We showed that the attenuated AQP3 level may contribute to low sperm motility via reducing glycerol for energy production in sperm tails of asthenozoospermia. Increasing CASP3 activity could indirectly show the status of active apoptosis in individuals with asthenozoospermia.

Abstract
OBJECTIVES The mechanical index has long been one of the main criteria used to assess the safety limits for therapeutic medical applications. However, the safety of the mechanical index parameter is considered to be unknown in male fertility, which has a very significant role in vitro conditions. In this study, the effect of cavitation interactions due to mechanical index regions was evaluated on spermatogonial stem cells. METHODS The acoustic pressure and mechanical index equations at the low intensities and the intended frequency were modeled and solved. The mechanical index average of 40 kHz frequency was selected as subthreshold, 0.70, and above the cavitation threshold. Neonatal spermatogonial stem cells were cultured. Spermatogonial stem cells are stimulated by low-level ultrasound for 5 days and colonization and viability evaluated on the seventh day. RESULTS Based on modeling, the mechanical index average was chosen as 0.40, 0.51, 0.75, and 0.89. The mechanical index of 0.40 and 0.89 resulted in a number of colonies of 93 ± 4 and 32 ± 4, respectively. An increase in colony diameter could be observed for a 0.40 mechanical index during all days of the culture that in the culture on the seventh day had the largest average colony diameter of 174.05 ± 1.22 μm in comparison with other groups (p < 0.05). The cell viability was not significantly different among the groups. CONCLUSION The results suggest that a low-intensity ultrasound of 40 kHz with a 0.40 mechanical index can be effective in increasing the proliferation and colonization of spermatogonia in stem cells during culture.

Abstract
Background: Spermatogenesis is a programmed route of germ cell proliferation and differentiation that could produce abundant numbers of spermatozoa. The antioxidants play a vital role in decreasing ROS production in cells, therefore plants extract administration with antioxidant property can prevent of cell damage. In the present study, antioxidant effects of Calligonum extract on proliferation and colonization rate of spermatogonial cells was assessed. Materials and Methods: After isolation and culture of spermatogonial stem cells (SSCs) from neonatal mice (4-5 day old) and identification by PLZF and Oct4 markers, the therapeutic effect of Calligonum comosum extract was measured on the cells treated with H2O2. Induced oxidative stress cells were treated with 10 μg/ml extract for 3 weeks. ROS levels were assessed by flow cytometry, proliferation by cell count and TAC by FRAP assay. Also, the apoptosis rate was measured with P53 and Bax genes by real time PCR method. Results: After three weeks of treatment, the Calligonum group showed significantly lower ROS level relative to the H2O2 group. Antioxidants levels were in Calligonum group significantly higher than the H2O2 group (P≤0.05). There was a strong inverse relationship between the two groups. Proliferation and colonization rate were in Calligonum + H2O2 group significantly higher than H2O2 group alone (P≤0.05). Finally, the results of the study indicated that P53 and Bax expression decreased in Calligonum + H2O2 group compared to H2O2 group. Conclusion: The results of present study expressed that Calligonum as a plant with antioxidant effect could reduce the level ofROS, and increase proliferation and colonization rate and TAC. In other hand, 30 μM doses of H2O2increased oxidative stress and apoptosiswhile decreased proliferation of SSCs.

Abstract
Background Biological scaffolds are derived by the decellularization of tissues or organs. Various biological scaffolds, such as scaffolds for the liver, lung, esophagus, dermis, and human testicles, have been produced. Their application in tissue engineering has created the need for cryopreservation processes to store these scaffolds. Objective The aim was to compare the two methods for prolong storage testicular scaffolds. Materials and Methods In this experimental study, 20 male NMRI mice (8 wk) were sacrificed and their testes were removed and treated with 0.5% sodium dodecyl sulfate followed by Triton X-100 0.5%. The efficiency of decellularization was determined by histology and DNA quantification. Testicular scaffolds were stored in phosphate-buffered saline solution at 4°C or cryopreserved by programmed slow freezing followed by storage in liquid nitrogen. Masson's trichrome staining, Alcian blue staining and immunohistochemistry, collagen assay, and glycosaminoglycan assay were done prior to and after six months of storage under each condition. Results Hematoxylin-eosin staining showed no remnant cells after the completion of decellularization. DNA content analysis indicated that approximately 98% of the DNA was removed from the tissue (p = 0.02). Histological evaluation confirmed the preservation of extracellular matrix components in the fresh and frozen-thawed scaffolds. Extracellular matrix components were decreased by 4°C-stored scaffolds. Cytotoxicity tests with mouse embryonic fibroblast showed that the scaffolds were biocompatible and did not have a harmful effect on the proliferation of mouse embryonic fibroblast cells. Conclusion Our results demonstrated the superiority of the slow freezing method for prolong storage of testicular scaffolds.

Abstract
OBJECTIVE Spermatogonial stem cells (SSCs) are able to form embryonic stem-like cells (ES-like cells) and embryonic bodies (EBs). Low-intensity ultrasound stimulation (LIUS) has positive effects on the growth and differentiation of the different cells. In this study, we tried to investigate the effects of LIUS on SSC differentiation to ES-like cells. MATERIALS AND METHODS SSCs were isolated from neonatal mice and their identification was confirmed by tracking of PLZF, Oct-4, and C-Kit proteins. The SSCs and Sertoli cells were co-cultured in DMEM/F12 supplemented with 15% FBS and LIF. SSCs stimulated by LIUS with 200mW/CM2 intensity. Characterization of obtained ES-like cells was confirmed with Sox2, Oct-4, and SSEA-1 immunofluorescence staining. Also, real-time PCR was performed to analyse the expression of c-Myc and Nanog genes in ES-Like Cells and Stra8, Piwil2 and Plzf genes in SSCs after 21 days of the in vitro culture. RESULTS Our results showed c-Kit, PLZF and Oct-4 proteins were expressed positively in SSCs and Sox2, Oct-4, SSEA-1 in the ES-like cells by immunocytochemistry. The results of flow cytometry showed a significant increase in expression of c-Myc and Nanog in ES-like cells compared to SSCs (p<.05), whereas the Stra8, Piwil2, and Plzf became down-regulated during 21 days of culture. ES-like markers cell SSEA-1, Sox2 and Oct-4 were increased in the LIUS group compared to the control group (p<.05). CONCLUSION The results indicated that ES-like cells with pluripotency characteristics were derived from SSCs.

Abstract
PURPOSE Generating functional gametes for patients with male infertility is of great interest. We investigated different cultural systems for proliferation of SSCs derived from obstructive azoospermic patients. MATERIALS AND METHODS Testicular cells were obtained from men with obstructive azoospermia. After enzymatic digestion process, cells were assigned to various groups: culture of SSCs in the dish without cover (control group), co-culture of SSCs with infertile Sertoli cells (I), co-culture of SSCs with fertile Sertoli cells (II), culture of SSCs on nanofiber (covered with laminin) (III), culture of testicular cell suspension (IV). Then cells were cultured and colony formation, gene-specific methylation (by MSP), quantitative genes expression of pluripotency (Nanog, C-Myc, Oct-4) and specific germ cell (Integrin α6, Integrin β1, PLZF) genes were evaluated in five different culture systems. RESULTS Our findings indicate a significant increase in the number and diameter of colonies in IV group in compare to control group and other groups. Expression of germ specific genes in IV group were significantly increased (P ≤ 0.05) and levels of expression of pluripotency genes were significantly decreased in this group (P ≤ 0.05) compared with other groups. Gene-specific pattern of methylation of examined genes showed no changes in culture systems during the culture era. CONCLUSION A microenvironment capable of controlling the proliferation of cell colonies can be restored by testicular cell suspension.

Abstract
OBJECTIVE The aim of this study was to provide a non-invasive imaging method to evaluate the physical and mechanical parameters as a novelty method during skin photoaging. METHODS In order to evaluate the process of skin damage, 25 mice (C57BL6) were exposed to UVB radiation (0.03 mW/cm2 ), 5 times a week for 5 weeks. The thickness of the epidermal and dermal layers was measured weekly from the ultrasound images (40 MHz). The elastic parameters of the skin were estimated from the processing of the sequential ultrasound images with the motion detection algorithm during the injury generation process. RESULTS The thickening, Young modulus, and shear modulus of the dermal and epidermal layers during the UVB damage process significantly increased during the 5-week study period (P < .05). In addition, the percentage of changes in the thickness of the epidermal layer (0.22 ± 0.01 mm in day 0 to 0.37 ± 0.02 mm in day 35) and dermal layer (0.57 ± 0.05 mm in day 0 to 0.90 ± 0.08 mm in day 35) increased by 68% and 57%, respectively. Furthermore, Young modulus (154.41 ± 8.8 kPa) was 11 times more than that of non-irradiated skin (14.90 ± 2.2 kPa) and the shear modulus (2.33 ± 0.04 kPa) was 2.2 times more than non-irradiated skin (1.06 ± 0.04 kPa). CONCLUSION With processing the sequential ultrasound images and extracting the thickening, the elasticity of the skin layers can detect skin lesions by UVB radiation.

Abstract
PURPOSE Recreational use of illicit drugs is one of the main factors affecting male fertility. However, the mechanisms of heroin smoke-associated damage to mature spermatozoa are still completely unknown. The aim of this study was to concomitantly examine the levels of protamine-2 gene and protein concentrations, the amount of miRNA-122 in seminal plasma and semen analysis findings in heroin-addicted men. MATERIALS AND METHODS In a case control study, twenty-four fertile men that lacked any recreational drug abuse were considered as the healthy group, and 24 addicted men who used only heroin for at least four months were selected as the addicted group. Semen samples were gathered by masturbation after 2 - 5 days of sexual abstinence. Following the preparation of a semen analysis by computer-assisted sperm analysis according to WHO (2010), the level of protamine-2 gene expression in sperm and miRNA-122 in seminal plasma was measured using real-time sqPCR. Also, protamine-2 protein concentrations were quantified by nuclear protein extraction, SDS-Page and western blotting. RESULTS Among the studied variables, body mass index (27.75±0.88 vs. 22.30±0.36, p=0.001), seminal pH (7.79±0.06 vs. 7.58±0.06, p=0.003), white blood cell count in semen (1.69±0.41 vs. 8.61±1.73, p=0.001), motility (65.51±2.57 vs. 41.96±3.58, p=0.001) and survival rate (87.41±1.00 vs. 71.50±4.59, p=0.002) of sperm cells was significantly different between the healthy and addicted groups. In addition, the levels of protamine-2 gene and protein expression in the addicted group (0.05±0.02 and 0.10±0.02, respectively) were significantly lower than the healthy group (3.59±0.94 and 0.27±0.06, respectively) (p=0.002 and p=0.017, respectively). Seminal miRNA-122 levels in addicted men (3.51±0.73) were statistically higher than in healthy men (1.52±0.54) (p=0.034). However, there were some significant relationship between the studied parameters and addiction (p<0.05). CONCLUSION This is one study on human infertility that evaluates the effects of heroin on protamine deficiency and seminal small RNAs expression levels. Heroin abuse may lead to male infertility by causing leukocytospermia, asthenozoospermia, protamine deficiency, and seminal plasma miRNA profile alteration.

Abstract
Background The study aimed to evaluate the impact of Calligonum extract and US radiation on sperm parameters of cryopreserved human semen samples. Materials and Methods In this experimental study, twenty-five semen specimens were obtained from healthy semen donors and incubated in human tubal fluid (HTF) medium supplemented with 10% human serum albumin (HSA) for 45 minutes. Samples were treated with Calligonum extract (10 μg/ml) alone (CGM group) and US radiation (LIPUSexposed group) alone or a combination of both treatments (CGM+LIPUS). The US group received US stimulation (in both continuous and pulsed wave modes) at a frequency of 1 MHZ and intensity of 200 mW/cm2 for 200 seconds. Sperm morphology was assessed by Diff-Quik staining. The DNA fragmentation was evaluated the Halo sperm kit. Sperm parameters was analyzed by a computer-assisted semen analysis system. Reactive oxygen species (ROS) was assessed by flow cytometry. Results The results showed that the treatment with Calligonum extract significantly (P<0.05) increased the progressive motility of spermatozoa in the CGM group as compared with the control group. The application of low-intensity US significantly (P<0.05) decreased the motility and viability of spermatozoa in the US group when compared with the control group. Our findings also indicated that the use of both low-intensity US in continuous mode and Calligonum extract slightly increased progressive motility; however, such an increase was not statistically significant. The rate of DNA fragmentation was considerably higher (P<0.05) in control and LIPUS-exposed groups than the other groups. Conclusion Treatment of spermatozoa with Calligonum extract slightly improved the sperm parameters due to its antioxidant activity, on the other hand, according to our results, US radiation did not improve sperm parameters which may be due to interference with the motility of sperm, as well as its physical effects on spermatozoa.

Abstract
INTRODUCTION The effect of fullerene nanoemulsion on skin wrinkle repair in an animal model was evaluated using ultrasonic images processing. METHODS Wrinkles were created in C57BL6 mice during 35 days of UVB radiation. Then, to investigate the therapeutic effect of fullerene nanoemulsions, mice were divided into three groups of control, UVB radiation, and treatment with fullerene nanoemulsion. Stable fullerene nanoemulsions were prepared using shear equalization. The therapeutic effect of fullerene nanoemulsion was investigated by extracting the skin thickness and mechanical parameters. Histology studies were performed to confirm the reliability of the treatment. RESULTS A significant decrease was observed in the thickness of the epidermis and dermis layers (43% and 36%), Young modulus (27%), and the shear modulus (20%) of the skin on day 28 of the fullerene nanoemulsion treatment. Skin stiffness obtained by tensiometry on day 28 of the treatment showed a 48% reduction in the treatment group compared with the control group. Histological results confirmed the effect of fullerene nanoemulsions on wrinkle repair. CONCLUSION The healing effect of fullerene nanoemulsion in wrinkle repair was confirmed. To study the skin repair, parameters including Young modulus, the shear modulus, and skin layer thickness can be calculated using ultrasonic images processing.

Abstract
OBJECTIVE The introduction of alternative systems in vivo is very important for cancer patients who are treated with gonadotoxic treatment. In this study, we examine the progression of the spermatogenesis process after human spermatogonial stem cell (SSCs) transplantation in vivo and in tissue culture conditions. MATERIALS AND METHODS Human SSCs were obtained from a Testicular Sperm Extractions (TESE) sample, and characterization of these cells was confirmed by detecting the promyelocytic leukemia zinc finger (PLZF) protein. These cells, after being labeled with Di-alkyl Indocarbocyanine (DiI), were transplanted to adult azoospermia mouse testes treated with Busulfan 40mg/kg. The host testicular tissue culture was then considered a test group and in vivo transplant a control group. After 8 weeks, immunohistochemical, morphometric and molecular studies were performed. RESULTS The results of morphometric studies indicated that the mean number of spermatogonia, spermatocytes, and spermatids in the test groups was significantly lower than in the control group (P<0.05) and most of the cells responded positively to DiI tracing. Immunohistochemical study in both groups revealed expression of PLZF, Synaptonemal complex protein 3 (SCP3) and Acrosin Binding Protein (ACRBP) proteins in spermatogonial cells, spermatocyte and spermatozoa, respectively. Also, PLZF, Transition Protein 1 (TP1) and Tektin-1 (Tekt1) human-specific genes had a significant difference in the between test groups and control groups (P<0.05) in molecular studies. CONCLUSION These results suggest that the conditions of testicular tissue culture after transplantation of SSCs can support spermatogenesis resumption, as well as in an in vivo condition.

Abstract
This study proposes a microfluidic device capable of separating monocytes from a type of cancer cell that is called T-cell acute lymphoblastic leukemia (RPMI-8402) in a continuous flow using negative and positive dielectrophoretic forces. The use of both the hydrodynamic and dielectrophoretic forces allows the separation of RPMI-8402 from monocytes based on differences in their intrinsic electrical properties and sizes. The specific crossover frequencies of monocytes and RPMI-8402 cells have been obtained experimentally. The optimum ranges of electrode pitch-to-channel height ratio at the cross sections with different electrode widths have been generally calculated by numerical simulations of the gradients of the electric field intensities and calculation their effective values (root-mean-square). In the device, the cell sorting has been conducted empirically, and then, the separation performance has been evaluated by analyzing the images before and after dielectrophoretic forces applied to the cells. In this work, the design of a chip with 77 μm gold-titanium electrode pitch was investigated to achieve high purity of monocytes of 95.2%. The proposed device can be used with relatively low applied voltages, as low as 16.5 V (peak to peak). Thus, the design can be used in biomedical diagnosis and chemical analysis applications as a lab-on-chip platform. Also, it can be used for the separation of biological cells such as bacteria, RNA, DNA, and blood cells.

Abstract
Objective We present a four-branch model of the dielectrophoresis (DEP) method that takes into consideration the
inherent properties of particles, including size, electrical conductivity, and permittivity coefficient. By using this model,
bioparticles can be continuously separated by the application of only a one-stage separation process.
Materials and Methods In this numerical study, we based the separation process on the differences in the particle
sizes. We used the various negative DEP forces on the particles caused by the electrodes to separate them with a high
efficiency. The particle separator could separate blood cells because of their different sizes.
Results Blood cells greater than 12 μm were guided to a special branch, which improved separation efficiency because
it prevented the deposition of particles in other branches. The designed device had the capability to separate blood cells
with diameters of 2.0 μm, 6.2 μm, 10.0 μm, and greater than 12.0 μm. The applied voltage to the electrodes was 50 V
with a frequency of 100 kHz.
Conclusion The proposed device is a simple, efficient DEP-based continuous cell separator. This capability makes it
ideal for use in various biomedical applications, including cell therapy and cell separation, and results in a throughput
increment of microfluidics devices.

Abstract
Background The aim of this study was to investigate two enkephalin-degrading enzymes, aminopeptidase N (APN/
CD13) and endopeptidase (NEP/CD10), gene and protein expression levels in sperm samples of fertile and heroin-
addicted men, and the correlation between their expressions and semen quality. Materials and Methods In this case-controlled study, semen was collected from 24 normozoospermic healthy
(as a control group) and 24 heroin-addicted men donors (as case or addiction group). Sperm cells isolated by Cook
Medical gradient (40-80%) and followed up by swim-up techniques were used for real-time quantitative polymer-
ase chain reaction (qPCR) and flow cytometry techniques to assess APN/CD13 and NEP/CD10 genes and proteins
subsequently. Semen parameters were analyzed by computer-assisted sperm analysis. Results The findings revealed that there were significant differences in sperm total motility (41.07 ± 3.63 vs. 63.03
± 3.31 %, P=0.0001), progressive motility (35.21 ± 2.64 vs. 20.93 ± 3.22%, P=0.001) and viability (69.9 ± 4.69 vs.
86.81 ± 1.26 %, P=0.002) in the addicted group vs. control ones. APN and NEP gene expression levels in the addicted
group decreased compared with the control ones (1.00 ± 0.67 vs. 0.36 ± 0.13, P= 0.008 and 1.07 ± 0.11 vs. 0.52 ± 0.12
0.002, respectively). Flow cytometry analysis showed that the average percent of APN/CD13 in heroin consumers
significantly decreased compared with the healthy ones, while NEP/CD10 rate between two groups was similar. We
also observed that duration of drug dependence is correlated with sperm viability (r=-0.627, P=0.016) and motility
(r=-0.410, P=0.05), NEP (r=-0.434, P= 0.049), and APN (r=-0.641, P=0.002) gene expression levels. Conclusion We conclude that semen quality and enkephalin-degrading enzymes were altered in heroin-addicted men.

Abstract
Different antioxidants have been introduced to reduce oxidative stress during the cryopreservation. The main goal of this study was to evaluate the effects of canthaxanthin on human sperm parameters during the freeze-thaw process. This study was performed on 25 normozoospermic semen samples dividing into five groups including 0, 0.1, 1, 10, and 25 µM of canthaxanthin. The prepared spermatozoa were cryopreserved by rapid freezing technique. Sperm motility, viability (eosin-nigrosin), morphology (Papanicolaou), acrosome reaction (double staining), DNA denaturation (acridine orange), chromatin packaging (aniline blue and toluidine blue), and DNA fragmentation (sperm chromatin dispersion test) were evaluated before freezing and after thawing. All sperm parameters after thawing significantly were decreased compared to before freezing. Twenty-five micromolar canthaxanthin could significantly improve the progressive and total motility, viability, normal morphology, chromatin packaging, acrosome integrity and DNA denaturation and fragmentation. Ten micromolar canthaxanthin significantly improved total motility, viability, normal morphology, chromatin packaging, acrosome integrity and DNA denaturation and fragmentation. Whereas, in 1 µM group, there were significant differences only in improvement of acrosome integrity, chromatin packaging (toluidine blue) and DNA denaturation and fragmentation. But, in 0.1 µM group, there were no significant differences in any of measured parameters. It seems that canthaxanthin ameliorates detrimental effects of cryopreservation on human sperm parameters.

Abstract
Objective Applications of biological scaffolds for regenerative medicine are increasing. Such scaffolds improve cell
attachment, migration, proliferation and differentiation. In the current study decellularised mouse whole testis was used
as a natural 3 dimensional (3D) scaffold for culturing spermatogonial stem cells.
Materials and Methods In this experimental study, adult mouse whole testes were decellularised using sodium
dodecyl sulfate (SDS) and Triton X-100. The efficiency of decellularisation was determined by histology and DNA
quantification. Masson’s trichrome staining, alcian blue staining, and immunohistochemistry (IHC) were done for
validation of extracellular matrix (ECM) proteins. These scaffolds were recellularised through injection of mouse
spermatogonial stem cells in to rete testis. Then, they were cultured for eight weeks. Recellularised scaffolds were
assessed by histology, real-time polymerase chain reaction (PCR) and IHC.
Results Haematoxylin-eosin (H&E) staining showed that the cells were successfully removed by SDS and Triton
X-100. DNA content analysis indicated that 98% of the DNA was removed from the testis. This confirmed that our
decellularisation protocol was efficient. Masson’s trichrome and alcian blue staining respectively showed that
glycosaminoglycans (GAGs) and collagen are preserved in the scaffolds. IHC analysis confirmed the preservation of
fibronectin, collagen IV, and laminin. MTT assay indicated that the scaffolds were cell-compatible. Histological evaluation
of recellularised scaffolds showed that injected cells were settled on the basement membrane of the seminiferous
tubule. Analyses of gene expression using real-time PCR indicated that expression of the Plzf gene was unchanged
over the time while expression of Sycp3 gene was increased significantly (P=0.003) after eight weeks in culture,
suggesting that the spermatogonial stem cells started meiosis. IHC confirmed that PLZF-positive cells (spermatogonial
stem cells) and SYCP3-positive cells (spermatocytes) were present in seminiferous tubules.
Conclusion Spermatogonial stem cells could proliferate and differentiated in to spermatocytes after being injected in the
decellularised testicular scaffolds.

Abstract
Bone defects remain a significant health issue and a major cause of morbidity in elderly patients. Composites based on collagen/calcium phosphate have been widely used for bone repair in clinical applications, owing to their comparability to bone extracellular matrix. This study aimed to evaluate the effects of a scaffold of collagen/calcium phosphate (COL/β-TCP) on bone formation to assess its potential use as a bone substitute to repair bone defects. Bilateral full-thickness critically sized calvarial defects (8 mm in diameter) were created in New Zealand white rabbits and treated with COL/β-TCP or COL scaffolds. One defect was also left unfilled as a control. Bone regeneration was assessed through histological evaluation using hematoxylin and eosin and Masson's trichrome staining after 4 and 8 weeks. Alizarin Red staining was also utilized to observe the mineralization process. Our findings indicated that COL/β-TCP implantation could better enhance bone regeneration than COL and exhibited both new bone growth and scaffold material degradation.

Abstract
In vitro derivation of germ cells from different stem cell sources has been challenging in the treatment of male infertility. MicroRNAs (miRNAs) have an essential role in gene expression at post-transcriptional level. The aim of this research was to find more about miRNA-17 and miRNA-146 expression during differentiation of spermatogonial stem cell like cells (SSC like cells) from mouse bone marrow mesenchymal stem cells (BMSCs) through bone morphogenic protein 4 (BMP4) and retinoic acid (RA) induction. BMSCs were treated with BMP4 to produce primordial germ cell like cells (PGC like cells). The cells were differentiated into SSC like cells by an inducer cocktail including RA, leukemia inhibitory factor (LIF) and basic fibroblast growth factor (bFGF). The PGC like cells and SSC like cells were evaluated for pluripotency (Nanog, Oct-4) and germ cell specific gene (Piwil2, Plzf, Dazl, and Stra8) expression, protein expression (Plzf, Stra8), and miRNA-17 and miRNA-146 mRNA expression. Our results showed that BMP4 leads to Dazl upregulation and Nanog downregulation expression in PGC like cells. RA upregulated Stra8 and Piwil2, and downregulated Nanog and Oct-4. MiRNA-17 and miRNA-146 expression decreased significantly in SSC like cells after RA treatment. This research indicated the aberrant miRNA-17 and miRNA-146 expression in SSC like cells in comparison with SSCs. Downregulation of the two miRNAs using RA in the stimulated undifferentiated state could probably be one of the key factors of SSC like cell arrest.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Calligonum comosum is a desert plant that is applied in traditional folkloric medicine for the treatment of abnormally heavy or prolonged menstruation and menstrual cramps. Moreover, it has been suggested for the treatment of infertility-causing conditions. Its bioactive chemical constituents inhibit multiple processes, such as angiogenesis, inflammation and invasive tissue growth, which may be beneficial in the therapy of endometriosis. AIM OF THE STUDY We investigated the effects of Calligonum comosum on the development of endometriotic lesions. MATERIALS AND METHODS We evaluated the anti-angiogenic activity of Calligonum comosum ethyl acetate fraction (CCEAF) in different in vitro angiogenesis assays. Moreover, we surgically induced endometriotic lesions in BALB/c mice, which received 50 mg/kg Calligonum comosum total extract (CCTE) or vehicle (control) over 4 weeks. The growth, cyst formation, vascularization and immune cell infiltration of the lesions were assessed with high-resolution ultrasound imaging, caliper measurements, histology and immunohistochemistry. RESULTS CCEAF doses of up to 10 μg/mL did not impair the viability of human dermal microvascular endothelial cells (HDMEC), but dose-dependently suppressed their migration, tube formation and sprouting, indicating a substantial anti-angiogenic effect of CCEAF. Furthermore, CCTE significantly inhibited the growth and cyst formation of developing murine endometriotic lesions when compared to vehicle-treated controls. This was associated with a reduced vascularization, cell proliferation and immune cell infiltration. CONCLUSIONS Our findings show that Calligonum comosum targets multiple, fundamental processes in the pathogenesis of endometriosis, which may be beneficial for the treatment of this common gynecological disorder.

Abstract
PURPOSE To investigate the effects of heroin on sperm parameters, histone-to-protamine transition ratios in mature sperm, and serum reproductive hormone levels in active heroin users. MATERIALS AND METHODS Semen and blood samples were collected from 25 men who used only heroin for at least 12 months and the same number healthy men who did not use any drugs and did not suffer from infertility problems. Computer-based analysis, Aniline blue staining, and hormonal assessment were performed to provide valuable new information on the relationship between addiction and semen profile and serum reproductive hor-mone levels. RESULTS Our finding showed that semen pH (7.8 vs. 7.75), sperm motility (42.93 ± 3.89% vs. 68.9 ± 2.68%), and viability (73.27 ± 3.85% vs. 86.48 ± 1.05%), and sperm histone replacement abnormalities (32.33 ± 10.89% vs. 5.56 ± 0.85%) were significant differences in addicted group vs. non-exposed ones (P ? .05). In addition, serum sex hormone levels were not significantly differed between groups. There was a correlation between the amount of daily heroin consumption and LH level. We also observed that duration of drug dependence is correlated with sperm abnormalities. CONCLUSION We concluded that heroin consumption affect sperm maturities such as histone-to-protamine ratio and impair semen profile in general and particularly sperm morphology and motility. Heroin may be considered as one of the idiopathic male infertility reason.

Abstract
This study aimed to induce spermatogenesis in azoospermic testis through induced pluripotent stem cells (iPSCs) derived spermatogonial stem cell-like cells (SSCLCs) after iPSCs in vivo and in vitro transplantation and three-dimensional organ culture. DiI-labelled mouse iPSCs were transplanted to azoospermic testis mouse model (pretreated by busulfan 40 mg/kg). This study was designed based on two experimental groups. In experimental group 1(in vivo) labelled iPSCs were transplanted to azoospermic host testis. In experimental group 2 (in vitro) after cell transplantation, fragments of host testes were set as 3D organ culture and testis without cells transplantation served as the control group by the same method. The samples were evaluated by tracing DiI, cell homing, immunohistochemistry, and quantitative RT PCR assays. 2 weeks after iPSCs transplantation, the molecular assessment showed that Plzf, Thy1, Vasa and Gfra1 expression were increased significantly (p ≤ .05) in host testis and labelled iPSCs co-localized by the Plzf and Thy1 markers expression in the base of seminiferous tubules. These findings suggest the ability of iPSCs to achieve homing in the testis niche and indicate the critical inductive role of microenvironment signals in the differentiation of iPSCs to spermatogonial stem cell-like cells.

Abstract
Background Sperm production is one of the most complex biological processes in the body. In vitro production of sperm is one of the most important goals of researches in the field of male infertility treatment, which is very important in male cancer patients treated with gonadotoxic methods and drugs. In this study, we examine the progression of spermatogenesis after transplantation of spermatogonial stem cells under conditions of testicular tissue culture. Results Testicular tissue samples from azoospermic patients were obtained and then these were freeze–thawed. Spermatogonial stem cells were isolated by two enzymatic digestion steps and the identification of these cells was confirmed by detecting the PLZF protein. These cells, after being labeled with DiI, were transplanted in azoospermia adult mice model. The host testes were placed on agarose gel as tissue culture system. After 8 weeks, histomorphometric, immunohistochemical and molecular studies were performed. The results of histomorphometric studies showed that the mean number of spermatogonial cells, spermatocytes and spermatids in the experimental group was significantly more than the control group (without transplantation) (P < 0.05) and most of the cells responded positively to the detection of DiI. Immunohistochemical studies in host testes fragments in the experimental group express the PLZF, SCP3 and ACRBP proteins in spermatogonial cells, spermatocyte and spermatozoa, respectively, which confirmed the human nature of these cells. Also, in molecular studies of PLZF, Tekt1 and TP1, the results indicated that the genes were positive in the test group, while not in the control group. Conclusion These results suggest that the slow freezing of SSCs can support the induction of spermatogenesis to produce haploid cells under the 3-dimensional testicular tissue culture.

Abstract
BACKGROUND Polycystic ovary syndrome (PCO) is one of the most common reasons for infertility. Calligonum as a plant possess some of the important antioxidants that can decrease oxidative stress. OBJECTIVE The effects of treatment with Calligonum as an antioxidant on ovary tissue of a PCO mouse model. MATERIALS AND METHODS Thirty female NMRI mice were divided into three groups (n=10/each): control, PCO, and Calligonum. We induced PCO model with single dose of Estradiol valerate (40 mg/kg). Then Calligonum (20 mg/kg) was intraperitoneally injected weekly for two months. The level of oxidative stress and total antioxidant capacity was assessed in the ovarian tissue by flow cytometry and fluorescence recovery after photobleaching, respectively, and the histological study was conducted by the morphometric method and embryo development with in vitro fertilization. RESULTS The obtained results showed that estradiol valerate was able to increase oxidative stress within the ovary and causes ovarian cysts after two months. The cyst formation was decreased in Calligonum group compared to PCO group (p=0.001). The percentage of pre-antral and antral follicles significantly decreased in Calligonum group compared to PCO group (p=0.001). The oxidative stress decreased in Calligonum group significantly compared to PCO group (p=0.001). Calligonum can significantly increase the total antioxidant capacity of ovarian tissue (p=0.001) as well as the percentage of in vitro fertilization compared to the PCO group. CONCLUSION Calligonum could decrease ovary cyst in PCO model, and improve in vitro fertilization rate. Also, Calligonum extract as an antioxidant could decrease oxidative stress in PCO model.

Abstract
BACKGROUND Spermatogonial stem cells (SSCs) are unique in mammals because they can transmit genetic information from generation to generation and it is of significant importance. In testes, Sertoli cells, peritubular myoid cells, Leydig cells and other interstitial cells contribute to the spermatogonial stem cell "niche". So, creation of niche in an in vitro condition that mimics the in vivo environment is essential to maintain functional characteristic of SSCs. OBJECTIVE In this review, we describe the impact of nanofiber scaffolds on the culture of SSCs derived from human-to-mouse. RESULTS Nanofiber Matrices mimic the architecture and size scale of the natural extracellular matrix (ECM). The scaffold provides more three-dimensional (3D), biomimicking and topographical signals to the cells and results in a more physiologically relevant cellular phenotype. Several investigators use different nanofiber scaffold-like carbon nanotubes (CNTs) scaffold, poly-L-lactic acid (PLLA) nanofiber scaffold, 3D soft agar culture system, human serum albumin (HSA)/tri calcium phosphate nanoparticles (TCPNPs) and electrospun polyamide nanofiber for proliferation and maintenance of self-renewal activity of the SSCs. CONCLUSION Application of nanofiber scaffolds for in vitro culture of the SSCs may produce spermatogonial stem cells that can be used in regenerative medicine, tissue engineering, assisted reproductive technology and in the treatment of infertility in pre-pubertal cancer patients.

Abstract
Objective In vitro transplantation (IVT) of spermatogonial stem cells (SSCs) is one of the most recent methods in
transplantation in recent decades. In this study, IVT and SSCs homing on seminiferous tubules of host testis in organ culture
have been studied.
Materials and Methods In this experimental study, human SSCs were isolated and their identities were confirmed by tracking
their promyelocytic leukemia zinc finger (PLZF) protein. These cells were transplanted to adult azoospermia mouse testes
using two methods, namely, IVT and in vivo transplantation as transplantation groups, and testes without transplantation of
cells were assigned in the control group. Then histomorphometric, immunohistochemical and molecular studies were done
after 2 weeks.
Results After two weeks, histomorphometric studies revealed that the number of subsided spermatogonial cells (SCs)
and the percentage of tubules with subsided SCs in IVT and in vivo groups were significantly more than those in the
control group (P<0.05). Immunohistochemical studies in the transplantation groups confirmed that the PLZF protein
was expressed in the cells subsided on the seminiferous tubule. Quantitative reverse-transcription polymerase chain
reaction (qRT-PCR) demonstrated that the PLZF gene expression was only positive in the transplantation groups, but
it was not significantly different between the IVT group and the in vivo group (P>0.05).
Conclusion Testicular tissue culture conditions after SSC transplantation can help these cells subside on the seminiferous
tubule basement membrane.

Abstract
BACKGROUND Establishment of a standardized animal endometriosis model is necessary for evaluation of new drug effects and for explaining different ethological aspects of this disease. For this purpose, we need a model which has more similarity to human endometriosis. OBJECTIVE Our objective was to establish an autologous endometriosis mouse model based on endogenous estrogen level and analyze the influence of estrus cycle on the maintenance of endometriotic lesions. MATERIALS AND METHODS In this experimental study, endometriotic lesions were induced in 52 female NMRI mice by suturing uterine tissue samples to the abdominal wall. The transplantation was either performed at proestrus/estrus or at metestrus/diestrus cycles. Urine-soaked beddings from males and also male vasectomized mice were transferred to the cages to synchronize and maintenance of estrus cycle in female mice. The mice were sacrificed after different transplantation periods (2, 4, 6 or 8 wk). The lesions size, macroscopic growth, model success rate, histological and immune-histochemical analyses were assessed at the end. RESULTS From a total of 200 tissue samples sutured into the peritoneal cavity, 83 endometriotic lesions were confirmed by histopathology (41.5%). Model success rate for proestrus/estrus mice was 60.7% vs. 79.2% for metestrus/diestrus mice. The endometriotic lesions had similar growth in both groups. Number of caspase-3, Ki67-positive cells and CD31-positive micro vessels were also similar in endometriotic lesions of two groups. CONCLUSION If we maintain the endogenous estrogen levels in mice, we can induce endometriosis mouse model in both proestrus/estrus and metestrus/diestrus cycle without any significant difference.

Abstract
BACKGROUND Spermatogonial stem cells are the foundation of spermatogenesis and male fertility. So, their maintenance and culture are very important. OBJECTIVE In this study, we assessed protective effects of the Calligonum on in vitro viability and apoptotic and antiapoptotic genes expression of spermatogonial stem cells. MATERIALS AND METHODS After 24 hr of culture, the spermatogonial stem cells were treated with 30 μM dose of H2O2 and then 10 μg/ml the Calligonum extract was added for 3 wks. Viability was assessed by Trypan blue, apoptosis using PI-Annexin and finally Bax, Bcl-2 and P53 genes expression by Real-Time Polymerase chain reaction. RESULTS After 3 wk of treatment, viability in the Calligonum extract+H2O2 group was significantly higher than H2O2 group alone (p=0.001). In the Calligonum extract+H2O2 group, apoptosis, as well as expression of apoptotic genes (Bax and P53), was significantly lower than the group treated with H2O2 alone. CONCLUSION The results of this study showed that 30 μM H2O2 increased apoptosis but decreased viability in spermatogonial stem cells. Calligonum has antioxidant properties that can reduce apoptosis, Bax and P53 expression and increase the viability and Bcl-2 expression.

Abstract
Background: In vitro spermatogenesis has a long research history beginning in the early 20th century. This organ culture method was therefore abandoned, and alternative cell culture methods were chosen by many researchers. Here, whether Tnp1, Tekt1, and Plzf, which play a crucial role in spermatogenesis, can be expressed during testis organ culture was assessed. Methods: Testes of 10 mouse pups were first removed, and the testis tissue was then separated into smaller pieces of seminiferous tubules. The size of the pieces was arbitrary; approximately 1 mg in weight or 1 mm3 in size when compacted. Afterwards, the testis tissue fragments (1–3) were transferred to the hexahedrons, incubated in a culture incubator and cultured for 12 weeks. Histological assessment and molecular evaluation were carried out at the end of the study. Results: The results showed that the expression of Tekt1 as a mitotic gene in mouse pups decreased significantly (p ≤ 0.05) in comparison to adult mouse testis. Meanwhile, the expression of Tnp1 as a meiotic gene increased significantly (p ≤ 0.05) as compared to neonate mouse testis at the beginning of the culture. The expression of Plzf showed no significant difference during the 12 weeks of culture (p ≥ 0.05). Based on histological study, different types of spermatocytes and post-meiotic stages of germ cells could not be detected. Conclusion: This kind of three-dimensional culture can induce expression of post-meiotic gene, Tnp1, but only at the molecular level and not beyond meiosis.

Abstract
BACKGROUND Sheep industry has taken steps toward transforming itself into a more efficient and competitive field. There are many varieties of sheep breeds in the world that each of them serves a useful purpose in the economies of different civilizations. Ghezel sheep is one of the Iranian important breeds that are raised for meat, milk and wool. Field of spermatogonial cell technologies provides tools for genetic improvement of sheep herd and multiple opportunities for research. Spermatogonial cells are the only stem cells capable of transmitting genetic information to future generations. METHODS This study was designed to extend the technique of isolation and in vitro proliferation of spermatogonial cells in Ghezel sheep. RESULTS Isolated cells were characterized further by using specific markers for type A spermatogonia, including PLZF. Also, sertoli cells were characterized by vimentin which is a specific marker for sertoli cells. After 10 days of co-culture, viability rates of the cells was above 94.7%, but after the freezing process the viability rates were 74 percent. CONCLUSION In this study, a standard method for isolation and in vitro proliferation of spermatogonial stem cells in Ghezel sheep was developed.

Abstract
Objective low intensity ultrasound (continues and pulsed) is a form of energy. Spermatogonial stem cells (SSCs) are
at the base of male fertility. This study investigated the effects of low intensity ultrasound stimulation (LIUS) and low
intensity pulsed ultrasound stimulation (LIUPS) on the expression of germ cell-specific and pluripotency genes in SSCs
in vitro.
Materials and Methods In this experimental study, isolated SSCs from neonatal male mice were cultured in Dulbecco’s
Modified Eagle’s Medium (DMEM) with 10% fetal bovine serum (FBS). In addition, to confirm identification of SSCs,
PLZF protein was detected positively in SSCs derived colonies. SSCs were stimulated by LIUS and LIUPS for 5 days,
followed by assessment of expression of integrin-α6 (Itga6) and β1 (Itgβ1), as two germ cell-specific genes, and Oct-
4, as a pluripotency gene, on day 21st by quantitive reverse transcriptase-polymerase chain reaction (qRT-PCR). To
investigate the proliferation rate and colonization of SSCs in different groups, counting whole number of the cells and
colonies as well as analysis of the respective diameters were performed on days 7th, 14th and 21st. Data was analyzed
by ANOVA test.
Results LIUS and LIUPS treatment of mouse SSCs increased expression of Itga6 and Itgβ1 genes in the experimental
groups, compared to the control group (P<0.05), whereas there was no significant difference between the groups,
regarding the expression of Oct-4 gene. These treatments maintained survival rate, while they increased proliferation
rate and colonization of SSCs during the first week of culture. However, within the second week, proliferation rate and
colonization were decreased in the experimental groups.
Conclusion These results suggested that LIUS and LIUPS treatment had good effect on SSCs proliferation and colonization,
based on the gene-specific marker expression during 21 days culture in vitro.

Abstract
Objective Re-vitrification of embryos immediately after thawing or after a culture period could be used to preserve
the extra embryos after embryo transfer. This study aims to clarify the effect of re-vitrification on Bax and Bcl-2 gene
expressions of compact and early blastocyst stage embryos.
Materials and Methods This experimental study was performed on mouse embryos. We collected 8-cell stage
embryos (n=400) from female mature mice, 60-62 hoursafter injection of human chorionic gonadotropin (hCG). The
embryos were divided into 5 groups: fresh (n=80), vitrified at the 8-cell stage (n=80), vitrified at the blastocyst stage
(n=80), vitrified at the 8-cell stage, and re-vitrified at the compact (n=80) and early blastocyst stages (n=80). Embryos
were vitrified by cryolock. We analyzed the developmental rates of the vitrified-warmed embryos with the chi-square
test. Quantitative polymerase chain reaction (qPCR) data were analyzed with SPSS version 16 using one-way analysis
of variance (ANOVA) followed by Tukey’s post hoc test. P<0.05 were considered statistically significant.
Results The expanded blastocyst formation rate showed a significant difference in re-vitrified embryos compared
with fresh embryos (P<0.05). However, this result was similar between the two re-vitrified groups. Our data showed
a significant difference in expression of the Bax and Bcl-2 genes between re-vitrified and fresh embryos (P<0.05).
Expressions of the Bax and Bcl-2 genes showed no significant difference between the two re-vitrified groups.
Conclusion Based on our study, re-vitrification could affect developmental rate and expressions of the Bax and Bcl2 genes.

Abstract
We developed collagen (COL) and collagen/beta tricalcium phosphate (COL/β-TCP) scaffolds with a β-TCP/collagen weight ratio of 4 by freeze-drying. Mouse bone marrow-derived mesenchymal stem cells (BMMSCs) were cultured on these scaffolds for 14 days. Samples were characterized by physicochemical analyses and their biological properties such as cell viability and alkaline phosphatase (ALP) activity was, also, examined. Additionally, the vascularization potential of the prepared scaffolds was tested subcutaneously in Wistar rats. We observed a microporous structure with large porosity (∼95-98%) and appropriate pore size (120-200 µm). The COL/β-TCP scaffolds had a much higher compressive modulus (970 ± 1.20 KPa) than pure COL (0.8 ± 1.82 KPa). In vitro model of apatite formation was established by immersing the composite scaffold in simulated body fluid for 7 days. An ALP assay revealed that porous COL/β-TCP can effectively activate the differentiation of BMMSCs into osteoblasts. The composite scaffolds also promoted vascularization with good integration with the surrounding tissue. Thus, introduction of β-TCP powder into the porous collagen matrix effectively improved the mechanical and biological properties of the collagen scaffolds, making them potential bone substitutes for enhanced bone regeneration in orthopedic and dental applications. © 2017 Wiley Periodicals, Inc.
