Abstract
Piracanjuba (Brycon orbignyanus) is an endangered fish species from the Neotropical region. The establishment of a cryobank using spermatogonial stem cells (SSCs) and subsequent production of a germline chimera is thus a promising strategy for such species. In the present work, procedures for the isolation and cryopreservation of piracanjuba SSCs and subsequent transplantation into sterile recipients were established. The piracanjuba SSCs were obtained by Percoll density gradient centrifugation and differential plating. SSC fractions were evaluated by relative ddx4 expression, alkaline phosphatase activity, and light microscopy. SSC cryopreservation was performed using five cryoprotectants at three different concentrations. The mix of the cells from the 20% and 30% Percoll density gradients showed 58.35 ± 0.03% purity of SSCs. The purity of SSCs increased to 66.00 ± 0.01% after differential plating. The relative ddx4 expression was 3.5 times higher in cells from the Percoll density gradient centrifugation than in the gonad and cells after differential plating. Propanediol (1 M) was the most effective cryoprotector evaluated (P = 1.000), showing 90.75 ± 1.85% cell viability. Freshly isolated and cryopreserved cells from the Percoll density gradient centrifugation were transplanted into a sterile male adult triploid hybrid with germ cell-less gonads. SSCs were observed in the germinal epithelium of the testes of recipients 20 days after transplantation. The results are promising for obtaining functional germline chimeras in Neotropical fish. Consequently, although the number of males used for the experiment was borderline, the procedures established here can be applied in future actions for the conservation and reconstitution of the piracanjuba in case of extinction.

Abstract
Cryopreservation of germ cells would facilitate the availability of cells at any time allowing the selection of donors and maintaining quality control for further applications such as transplantation and germline recovery. In the present study, we analyzed the efficiency of four cryopreservation protocols applied either to isolated cell suspensions or to testes fragments from Senegalese sole. In testes fragments, the quality of cryopreserved germ cells was analyzed in vitro in terms of cell recovery, integrity and viability, DNA integrity (fragmentation and apoptosis), and lipid peroxidation (malondialdehyde levels). Transplantation of cryopreserved germ cells was performed to check the capacity of cells to in vivo incorporate into the gonadal primordium of Senegalese sole early larval stages (6 days after hatching (dah), pelagic live), during metamorphosis (10 dah) and at post-metamorphic stages (16 dah and 20 dah, benthonic life). Protocols incorporating dimethyl sulfoxide (DMSO) as a cryoprotectant showed higher number of recovered spermatogonia, especially in samples cryopreserved with L-15 + DMSO (0.39 ± 0.18 × 106 cells). Lipid peroxidation and DNA fragmentation were also significantly lower in this treatment compared with other treatments. An important increase in oxidation (MDA levels) was detected in samples containing glycerol as a cryoprotectant, reflected also in terms of DNA damage. Transplantation of L-15 + DMSO cryopreserved germ cells into larvae during early metamorphosis (10 dah, 5.2 mm) showed higher incorporation of cells (27.30 ± 5.27%) than other larval stages (lower than 11%). Cryopreservation of germ cells using testes fragments frozen with L-15 + DMSO was demonstrated to be a useful technique to store Senegalese sole germline.

Culture of spermatogonial stem cells and use of surrogate sires as a breeding technology to propagate superior genetics in livestock production: A systematic review. Vet World 2021; 14:3235-3248. [PMID: 35153418 PMCID: PMC8829400 DOI: 10.14202/vetworld.2021.3235-3248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 11/15/2021] [Indexed: 11/16/2022] Open
Abstract
Background and Aim: Spermatogonial stem cells (SSCs) have previously been isolated from animals’ testes, cultured in vitro, and successfully transplanted into compatible recipients. The SSC unique characteristic has potential for exploitation as a reproductive tool and this can be achieved through SSC intratesticular transplantation to surrogate sires. Here, we aimed at comprehensively analyzing published data on in vitro maintenance of SSC isolated from the testes of livestock animals and their applications. Materials and Methods: The literature search was performed in PubMed, Science Direct, and Google Scholar electronic databases. Data screening was conducted using Rayyan Intelligent Systematic Review software (https://www.rayyan.ai/). Duplicate papers were excluded from the study. Abstracts were read and relevant full papers were reviewed for data extraction. Results: From a total of 4786 full papers screened, data were extracted from 93 relevant papers. Of these, eight papers reported on long-term culture conditions (>1 month) for SSC in different livestock species, 22 papers on short-term cultures (5-15 days), 10 papers on transfection protocols, 18 papers on transplantation using different methods of preparation of livestock recipients, and five papers on donor-derived spermatogenesis. Conclusion: Optimization of SSC long-term culture systems has renewed the possibilities of utilization of these cells in gene-editing technologies to develop transgenic animals. Further, the development of genetically deficient recipients in the endogenous germline layer lends to a future possibility for the utilization of germ cell transplantation in livestock systems.

Survivable potential of germ cells after trehalose cryopreservation of bovine testicular tissues. Cryobiology 2021; 101:105-114.

Abstract
Germplasm preservation of livestock or endangered animals and expansion of germline stem cells are important. The purpose of this study is to investigate whether supplementation of trehalose to the freezing medium (FM) reduces tissular damage and improves the quality of testicular cells in the cryopreserved bovine testicular tissues. We herein established an optimized protocol for the cryopreservation of bovine testicular tissues, and the isolation as well as culture of bovine germ cells containing spermatogonial stem cells (SSCs) from these tissues. The results showed that FM containing 10% dimethyl sulfoxide (Me2SO/DMSO), 10% knockout serum replacement (KSR) and 20% trehalose (FM5) combined with the uncontrolled slow freezing (USF) procedures has the optimized cryoprotective effect on bovine testicular tissues. The FM5 + USF protocol reduced the cell apoptosis, maintained high cell viability, supported the structural integrity and seminiferous epithelial cohesion similar to that in the fresh tissues. Viable germ cells containing SSCs were effectively isolated from these tissues and they maintained germline marker expressions in the co-testicular cells and co-mouse embryonic fibroblasts (MEF) feeder culture systems respectively, during the short-term culture. Additionally, upregulated transcriptions of spermatogenic differentiation marker C-KIT and meiotic marker SYCP3 were detected in these cells after retinoic acid-induced differentiation. Together, FM5 + USF is suitable for the cryopreservation of bovine testicular tissues, with benefits of reducing the apoptosis, maintaining the cell viability, supporting the testicular structure integrity, and sustaining the survival and differentiation potential of bovine germ cells containing SSCs.

Abstract
Testicular cell suspension (TCS) can be cryopreserved for male germ-line preservation and fertility restoration. We aimed to validate a cryopreservation protocol for TCS of domestic cat to be applied in endangered felids species. Testis tissue from adult domestic cats was enzymatically dissociated and spermatogenic cells were enriched. The resulting TCS was diluted in 7.5% or 15% Me2SO based medium. Slow and fast freezing methods were tested. We examined the effects of freezing approaches using two combinations of fluorescent dyes: Calcein-AM with Propidium iodide (C/PI) and SYBR14 with Propidium iodide (S/PI). Ploidy analysis of domestic cat fresh TCS revealed that the majority of testicular cells were haploid cells. Based on microscopic observation, two size populations (12.3 ± 2.3 μm and 20.5 ± 4 μm in diameter) were identified and presumed to be mainly spermatids and spermatocytes, respectively. Both evaluation methods proved higher viability of aggregated cells before and after cryopreservation compared with single cells, and superiority of low concentration of Me2SO (7.5%) in association with slow freezing to preserve viability of testicular cells. However, S/PI resulted in a more precise evaluation compared with the C/PI method. The combination of 7.5% Me2SO-based medium with slow freezing yielded post thaw viability of S/PI labeled aggregated (49.8 ± 20%) and single cells (31.5 ± 8.1%). Comparable results were achieved using testes of a Cheetah and an Asiatic golden cat. In conclusion, TCS from domestic cat can be successfully cryopreserved and has the potential to support fertility restoration of endangered felids species.

Abstract
The object of this study was to investigate if testis germ cell transplantation (TGCT) into a heterologous recipient would result in donor-origin spermatogenesis in the dromedary camel. First, we investigated a workable protocol for TGCT in camels, including donor cell isolation, enrichment by density gradient centrifugation (Percoll and Bovicoll), rete testis injection and microsatellite detection of donor and recipient genotypes. Second, the effects of three doses of Dolichos biflorus agglutinin (DBA), a glycoprotein that specifically binds to gonocytes or Type A spermatogonia, on testis germ cell depletion were investigated by direct injection into the rete testis of a male camel. Seven recipients were prepared with DBA treatment, two males were castrated at 4 weeks for depletion assessment and the remaining five received donor cells 4-6 weeks after treatment. On average, ~17 million cells were isolated per gram of testis tissue, with 19.5±1.9% DBA-positive (DBA+) cells. Percoll centrifugation yielded a 1.5-fold increase in DBA+ cells while Bovicoll centrifugation produced a 2.5-fold increase from the input cells of 18.6±2.1% DBA+ cells. Semen was collected from the recipients 13-20 weeks after transfer and the presence of donor DNA in the samples was determined using microsatellite markers. In two of the five recipients, all semen samples were shown to be positive for donor-derived cells. These results demonstrate for the first time that: (1) heterologous testicular germ cell transplantation in camels is feasible and the recipients are able to produce spermatozoa of donor origin and (2) DBA can be used effectively to deplete endogenous stem cells.

Abstract
We are entering an exciting epoch in livestock biotechnology during which the fundamental approaches (such as transgenesis, spermatozoa cryopreservation and artificial insemination) will be enhanced based on the modern understanding of the biology of spermatogonial stem cells (SSCs) combined with the outstanding recent advances in genomic editing technologies and in vitro cell culture systems. The general aim of this review is to outline comprehensively the promising applications of SSC manipulation that could in the nearest future find practical application in livestock breeding. Here, we will focus on 1) the basics of mammalian SSC biology; 2) the approaches for SSC isolation and purification; 3) the available in vitro systems for the stable expansion of isolated SSCs; 4) a discussion of how the manipulation of SSCs can accelerate livestock transgenesis; 5) a thorough overview of the techniques of SSC transplantation in livestock species (including the preparation of recipients for SSC transplantation, the ultrasonographic-guided SSC transplantation technique in large farm animals, and the perspectives to improve further the SSC transplantation efficiency), and finally, 6) why SSC transplantation is valuable to extend the techniques of spermatozoa cryopreservation and/or artificial insemination. For situations where no reliable data have yet been obtained for a particular livestock species, we will rely on the data obtained from studies conducted in rodents because the knowledge gained from rodent research is translatable to livestock species to a great extent. On the other hand, we will draw special attention to situations where such translation is not possible.

Abstract
Over the past 3 decades, and similar to the horse industry, fresh embryo transfer has been widely practiced on large commercial scales in different camelid species, especially the dromedary camel and alpaca. However, the inability to cryopreserve embryos significantly reduces its broader application, and as such limits the capacity to utilize elite genetic resources internationally. In addition, cryopreservation of the semen of camelids is also difficult, suggesting an extreme sensitivity of the germplasm to cooling and freezing. As a result, genetic resources of camelids must continue to be maintained as living collections of animals. Due to concerns over disease outbreaks such as that of the highly pathogenic Middle East Respiratory Syndrome in the Middle East and Asia, there is an urgent need to establish an effective gene banking system for camelid species, especially the camel. The current review compares and summarizes recent progress in the field of camelid embryo cryopreservation, identifying four possible reasons for the slow development of an effective protocol and describing eight future directions to improve the current protocols. At the same time, the results of a recent dromedary camel embryo transfer study which produced a high morphologic integrity and survival rate of Open Pulled Straw-vitrified embryos are also discussed.

Abstract
The conservation of sturgeons is of critical importance, and optimization of long-term storage is crucial to cell survival. This study aimed to examine the viability rates of several variations of sturgeon testicular cells storage at -80 °C for purpose of a short-term storage in a deep freezer or shipment on dried ice. Testes extracted from three immature fish were cut into small pieces, immersed in a cryomedium composed of phosphate buffered saline with 0.5% bovine serum albumin, 50 mM glucose, and 1.5 M ethylene glycol as a cryoprotectant, chilled from 10 to -80 °C at a cooling rate of 1 °C per min, and stored under varying conditions. Our results revealed a significant effect of storage conditions on the number of living and dead cells (p > 0.05). Samples that were stored for 7 days at -80 °C showed a considerable decline in terms of cell viability compared to samples stored for 2 days storage at -80 °C or in LN. This result indicated that testicular cells can be stored at -80 °C and/or on dry ice, for 2 days with minimum loss of viability.

The distribution of cryoprotectant (10% glycerol) and ice along the frozen plastic straw (the most useful container for freezing mammalian semen, oocytes and embryos) was studied by Raman scattering technique. Raman spectroscopy being a contactless, non-invasive tool was applied for the straws filled with the cryoprotectant solution and frozen by controlled rate programs commonly used for mammalian embryos freezing. Analysis of Raman spectra measured at different points along the straw reveals a non-uniform distribution of the cryoprotectant. The ratio between non-crystalline solution and ice was found to be increased by several times at the bottom side of the solution column frozen by the standard freezing program. The increase of the cryoprotectant fraction occurs in the area where embryos or oocytes are normally placed during their freezing. Possible effects of the cooling rate and the ice nucleation temperature on the cryoprotectant fraction at the bottom side of the solution column were considered. Our findings highlight that the ice fraction around cryopreserved embryos or oocytes can differ significantly from the averaged one in the frozen plastic straws.

Abstract
Propagation of bovine spermatogonial stem cells (SSCs) from the cryopreserved testicular tissue is essential for the application of SSCs-related techniques. To explore the appropriate conditions for in vitro culture of bovine spermatogonia (containing putative SSCs), Sertoli cell monolayer and serum concentration were set as two main control factors. Morphological examination showed that the intactness and structure of adult bovine testicular tissue were well maintained after cryopreservation. The enriched bovine spermatogonia were large round CD9 and promyelocytic leukemia zinc finger protein (PLZF) positive cells, with high nucleocytoplasmic ratios and multiple types including single, paired-, aligned-cells or grape cluster-like colonies in vitro. In Sertoli cell co-culture system, bovine spermatogonia attached quickly and proliferated obviously faster than those in the system without Sertoli cells. Serum-free media was no good for the attachment and proliferation of bovine spermatogonia. When 2.5%, 5% and 10% fetal bovine serum (FBS) was employed in the media, spermatogonia attached easily and divided quickly to form paired-, chained-cells or grape cluster-like colonies with comparable percentages in all groups. However, the contaminated somatic cells proliferated robustly in groups containing 5% and 10% FBS. Together, bovine spermatognia isolated from cryopreserved adult testis tissue express CD9 and PLZF, can survive and proliferate conspicuously in Sertoli cell co-culture system, and low serum provides an optimal condition for the survival and proliferation of bovine spermatogonia because of avoiding the rapid growth of testis somatic cells.

Abstract
Spermatogonial stem cells (SSCs) have the ability to self-renew and offer a pathway for genetic engineering of the male germ line. Cryopreservation of SSCs has potential value for the treatment of male infertility, spermatogonial transplantation, and so on. In order to investigate the cryopreservation effects of different cryoprotectants on murine SSCs, 0.2 M of low-density lipoproteins (LDL), trehalose and soybean lecithin were added to the cryoprotective medium, respectively, and the murine SSCs were frozen at -80°C or -196°C. The results indicated that the optimal recovery rates of murine SSCs in the cryoprotective medium supplemented with LDL, trehalose and soybean lecithin were 92.53, 76.35 and 75.48% at -80°C, respectively. Compared with freezing at -196°C, the optimum temperature for improvement of recovery rates of frozen murine SSCs, cryopreservation in three different cryoprotectants at -80°C, were 17.11, 6.68 and 10.44% respectively. The recovery rates of murine SSCs in the cryoprotective medium supplemented with 0.2 M LDL were significantly higher than that of other cryoprotectants (P < 0.05). Moreover, the recovery rates were demonstrated to be greater at -80°C compared with at -196°C (P < 0.05). In conclusion, 0.2 M of LDL could significantly protect murine SSCs at -80°C. In the freezing-thawing process, LDL is responsible for the cryopreservation of murine SSCs because it can form a protective film at the surface of membranes. However, more research is needed to evaluate and understand the precise role of LDL during the freezing-thawing of SSCs.

Abstract
A major benefit of advanced reproduction technologies (ART) in animal breeding is the ability to produce more progeny per individual parent. This is particularly useful with animals of high genetic merit. Testis germ cell transplantation (TGCT) is emerging as a novel reproductive technology with application in animal breeding systems, including the potential for use as an alternative to artificial insemination (AI), an alternative to transgenesis, part of an approach to reducing generation intervals, or an approach toward development of interspecies hybrids. There is one major difference in TGCT between rodents and some other species associated with immunotolerance in heterologous transplantation. In particular, livestock and aquatic species do not require an immunesuppression procedure to allow donor cell survival in recipient testis. Testicular stem cells from a genetically elite individual transplanted into others can develop and produce a surrogate male-an animal that produces the functional sperm of the original individual. Spermatozoa produced from testis stem cells are the only cells in the body of males that can transmit genetic information to the offspring. The isolation and genetic manipulation of testis stem cells prior to transplantation has been shown to create transgenic animals. However, the current success rate of the transplantation procedure in livestock and aquatic species is low, with a corresponding small proportion of donor spermatozoa in the recipient's semen. The propagation of donor cells in culture and preparation of recipient animals are the two main factors that limit the commercial application of this technique. The current paper reviews and compares recent progress and examines the difficulties of TGCT in both livestock and aquatic species, thereby providing new insights into the application of TGCT in food producing animals.

Abstract
INTRODUCTION A 3D-nanofiber scaffold acts in a similar way to the extracellular matrix (ECM)/basement membrane that enhances the proliferation and self-renewal of stem cells. The goal of the present study was to investigate the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on frozen-thawed neonate mouse spermatogonial stem cells (SSCs) and testis tissues. METHODS The isolated spermatogonial cells were divided into six culture groups: (1) fresh spermatogonial cells, (2) fresh spermatogonial cells seeded onto PLLA, (3) frozen-thawed spermatogonial cells, (4) frozen-thawed spermatogonial cells seeded onto PLLA, (5) spermatogonial cells obtained from frozen-thawed testis tissue, and (6) spermatogonial cells obtained from frozen-thawed testis tissue seeded onto PLLA. Spermatogonial cells and testis fragments were cryopreserved and cultured for 3 weeks. Cluster assay was performed during the culture. The presence of spermatogonial cells in the culture was determined by a reverse transcriptase polymerase chain reaction for spermatogonial markers (Oct4, GFRα-1, PLZF, Mvh(VASA), Itgα6, and Itgβ1), as well as the ultrastructural study of cell clusters and SSCs transplantation to a recipient azoospermic mouse. The significance of the data was analyzed using the repeated measures and analysis of variance. RESULTS The findings indicated that the spermatogonial cells seeded on PLLA significantly increased in vitro spermatogonial cell cluster formations in comparison with the control groups (culture of SSCs not seeded on PLLA) (P≤0.001). The viability rate for the frozen cells after thawing was 63.00% ± 3.56%. This number decreased significantly (40.00% ± 0.82%) in spermatogonial cells obtained from the frozen-thawed testis tissue. Both groups, however, showed in vitro cluster formation. Although the expression of spermatogonial markers was maintained after 3 weeks of culture, there was a significant downregulation for some spermatogonial genes in the experimental groups compared with those of the control groups. Furthermore, transplantation assay and transmission electron microscopy studies suggested the presence of SSCs among the cultured cells. CONCLUSION Although PLLA can increase the in vitro cluster formation of neonate fresh and frozen-thawed spermatogonial cells, it may also cause them to differentiate during cultivation. The study therefore has implications for SSCs proliferation and germ cell differentiation in vitro.

Abstract
Proliferation of spermatogonial stem cells (SSCs) in vitro system is very important. It can enhance SSCs numbers for success of transplantation and treatment of infertility in cancer patients. In this study, testicular cells that obtained from azoospermia patients (n=8) by enzymatic digestion were cryopreserved at the beginning and after 2 weeks of culture. Then, frozen-thawed SSCs were co-cultured on fresh Sertoli cells (experimental group 1), and frozen-thawed Sertoli cells (experimental group 2) for another 3 weeks. In control group, fresh SSCs were co-cultured on fresh Sertoli cells. Viability rate after enzymatic digestion was 93.4%±5.0. Frozen-thawed testicular cells after 2 weeks of culture had a significantly (P<0.05) higher percentage of living cells compared to frozen-thawed testicular cells at the beginning of culture (59.2±7.05 and 46.3±8.40 respectively). The number of colonies in the experimental group 1 was significantly higher than experimental group 2 (19.6±2.8 and 8.33±1.5, respectively, P<0.05). The diameter of the colonies in the experimental group 1 was significantly higher than control and experimental group 2 (P<0.05) after 3 weeks of culture (269.7±52.1, 204.34±24.1 and 112.52±23.5 μm, respectively). Cryopreservation technique will raise the possibility of banking SSCs for men who have a cancer-related illness and waiting for radiotherapy and/or chemotherapy.

Abstract
The objective of the current study was to identify an optimal time period for donor cell transplantation after irradiation in sheep. The testes of recipient rams were treated with a single dose of 15 Gray (Gy) irradiation followed by germ cell transplantation either 3 or 6 weeks later. Transplantation of donor cells at 6 weeks after irradiation resulted in production of donor sperm by all five recipient rams compared with 4 of 11 rams transplanted at 3 weeks. Rams transplanted 3 weeks post-irradiation appeared to show reduced libido and fertility. Two rams produced sperm with low motility (< 20%) and two other rams were azoospermic. More than 1 year after cell transfer, there were heavy infiltrates of CD45-positive cells and more fibrous tissue in 9 of 14 recipient testes (seven rams) that received cells 3 weeks after irradiation. Taken together, these results suggest that the interval between irradiation of recipients and germ cell transplantation affects the success rate of the procedure, with a 6-week interval preferable. The elevated inflammatory/immune reaction may be responsible, at least in part, for the reduced fertility and low libido observed in the rams that received cells 3 weeks post-irradiation.
