Abstract
Transgenic (Tg) animal technology is one of the growing areas in biology. Various Tg technologies, each with its own advantages and disadvantages, are available for generating Tg animals. These include zygote microinjection, electroporation, viral infection, embryonic stem cell or spermatogonial stem cell-mediated production of Tg animals, sperm-mediated gene transfer (SMGT), and testis-mediated gene transfer (TMGT). However, there are currently no comprehensive studies comparing SMGT and TMGT methods, selecting appropriate gene delivery carriers (such as nanoparticles and liposomes), and determining the optimal route for gene delivery (SMGT and TMGT) for producing Tg animal. Here we aim to provide a comprehensive assessment comparing SMGT and TMGT methods, and to introduce the best carriers and gene transfer methods to sperm and testis to generate Tg animals in different species. From 2010 to 2022, 47 studies on SMGT and 25 studies on TMGT have been conducted. Mice and rats were the most commonly used species in SMGT and TMGT. Regarding the SMGT approach, nanoparticles, streptolysin-O, and virus packaging were found to be the best gene transfer methods for generating Tg mice. In the TMGT method, the best gene transfer methods for generating Tg mice and rats were virus packaging, dimethyl sulfoxide, electroporation, and liposome. Our study has shown that the efficiency of producing Tg animals varies depending on the species, gene carrier, and method of gene transfer.

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.

Abstract
Porcine spermatogonia stem cells (pSSCs) are the only type of somatic stem cell that can pass genetic information to the successive generations. Little is known about pSSCs vitality in vitro, and due to their increasing importance in stem cell research, here, we optimized a protocol to culture pSSCs and explored their potential fate in vitro. Utilizing a feeder-free culture system with a 2D peptide-coating and small chemical molecules (including CHIR99021, Repsox, Vatamin C, Folic Acid, and CD Lipid Concentrate), we were able to prolong the culture time of pSSCs by at least three months compared to previous methods. Moreover, we found that pSSCs could proliferate and self-renew in the seminiferous tubules of infertile mice. However, they could not perform meiosis. Our study shows that this feeder-free culture system optimizes cell culture and may facilitate advanced research on SSC biology and genetic manipulation of germ cells.

Abstract
PURPOSE Spermatogonial stem cells (SSCs) are the source for the mature male gamete. SSC technology in humans is mainly focusing on preserving fertility in cancer patients. Whereas in livestock, it is used for mining the factors associated with male fertility. The review discusses the present status of SSC biology, methodologies developed for in vitro culture, and challenges ahead in establishing SSC technology for the propagation of superior germplasm with special reference to livestock. METHOD Published literatures from PubMed and Google Scholar on topics of SSCs isolation, purification, characterization, short and long-term culture of SSCs, stemness maintenance, epigenetic modifications of SSCs, growth factors, and SSC cryopreservation and transplantation were used for the study. RESULT The fine-tuning of SSC isolation and culture conditions with special reference to feeder cells, growth factors, and additives need to be refined for livestock. An insight into the molecular mechanisms involved in maintaining stemness and proliferation of SSCs could facilitate the dissemination of superior germplasm through transplantation and transgenesis. The epigenetic influence on the composition and expression of the biomolecules during in vitro differentiation of cultured cells is essential for sustaining fertility. The development of surrogate males through gene-editing will be historic achievement for the foothold of the SSCs technology. CONCLUSION Detailed studies on the species-specific factors regulating the stemness and differentiation of the SSCs are required for the development of a long-term culture system and in vitro spermatogenesis in livestock. Epigenetic changes in the SSCs during in vitro culture have to be elucidated for the successful application of SSCs for improving the productivity of the animals.

EZH2 expression and its role in spermatogonial stem cell self-renewal in goats. Theriogenology 2020; 155:222-231. [PMID: 32731005 DOI: 10.1016/j.theriogenology.2020.06.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 06/07/2020] [Accepted: 06/13/2020] [Indexed: 01/01/2023]
Abstract
Enhancer of zeste homolog 2 (EZH2) is a histone H3 lysine 27 (H3K27) methyltransferase that plays vital roles in mouse spermatogenesis. However, the expression pattern and role of EZH2 in goat spermatogonial stem cells (SSCs) is unknown. In the present study, we investigated EZH2 expression in the testis of postpubertal goats and its effect on the biological characteristics of goat SSCs. We found that EZH2 mRNA (P < 0.01) and protein (P < 0.05) expression was increased in the testes of postpubertal goats compared to that of prepubertal goats. Moreover, EZH2 was more highly expressed in goat SSCs than in Leydig cells (P < 0.01) and Sertoli cells (P < 0.01) as determined by qPCR, Western blot, and immunofluorescence. Compared to a negative control (NC), cell proliferation (P < 0.01) and viability (P < 0.01) were decreased in SSCs in which EZH2 was knocked down, and the G2/M phase of the cell cycle was blocked (P < 0.01), as determined by Edu staining, CCK-8 assay, and flow cytometry analysis. Additionally, the expression of CASP3, CASP9, and BAX was significantly increased (P < 0.01) while BCL2 expression was decreased (P < 0.01) in EZH2 knockdown SSCs. Notably, the expression of GDNF, a SSCs marker gene, and DAZL, a spermatogenesis-related gene, were significantly decreased (P < 0.01) while GFRA1 expression was significantly up-regulated (P < 0.01) in EZH2 knockdown SSCs. Our data suggest that EZH2 plays a pivotal role in the self-renewal of goat SSCs, and knockdown of EZH2 might impair spermatogenesis in goats.

Abstract
Sheep and goats are valuable livestock species that have been raised for their production of meat, milk, fiber, and other by-products. Due to their suitable size, short gestation period, and abundant secretion of milk, sheep and goats have become important model animals in agricultural, pharmaceutical, and biomedical research. Genome engineering has been widely applied to sheep and goat research. Pronuclear injection and somatic cell nuclear transfer represent the two primary procedures for the generation of genetically modified sheep and goats. Further assisted tools have emerged to enhance the efficiency of genetic modification and to simplify the generation of genetically modified founders. These tools include sperm-mediated gene transfer, viral vectors, RNA interference, recombinases, transposons, and endonucleases. Of these tools, the four classes of site-specific endonucleases (meganucleases, ZFNs, TALENs, and CRISPRs) have attracted wide attention due to their DNA double-strand break-inducing role, which enable desired DNA modifications based on the stimulation of native cellular DNA repair mechanisms. Currently, CRISPR systems dominate the field of genome editing. Gene-edited sheep and goats, generated using these tools, provide valuable models for investigations on gene functions, improving animal breeding, producing pharmaceuticals in milk, improving animal disease resistance, recapitulating human diseases, and providing hosts for the growth of human organs. In addition, more promising derivative tools of CRISPR systems have emerged such as base editors which enable the induction of single-base alterations without any requirements for homology-directed repair or DNA donor. These precise editors are helpful for revealing desirable phenotypes and correcting genetic diseases controlled by single bases. This review highlights the advances of genome engineering in sheep and goats over the past four decades with particular emphasis on the application of CRISPR/Cas9 systems.

Abstract
The reconstruction of critically sized bone defects remains a serious clinical problem because of poor angiogenesis within tissue-engineered scaffolds during repair, which gives rise to a lack of sufficient blood supply and causes necrosis of the new tissues. Rapid vascularization is a vital prerequisite for new tissue survival and integration with existing host tissue. The de novo generation of vasculature in scaffolds is one of the most important steps in making bone regeneration more efficient, allowing repairing tissue to grow into a scaffold. To tackle this problem, the genetic modification of a biomaterial scaffold is used to accelerate angiogenesis and osteogenesis. However, visualizing and tracking in vivo blood vessel formation in real-time and in three-dimensional (3D) scaffolds or new bone tissue is still an obstacle for bone tissue engineering. Multiphoton microscopy (MPM) is a novel bio-imaging modality that can acquire volumetric data from biological structures in a high-resolution and minimally-invasive manner. The objective of this study was to visualize angiogenesis with multiphoton microscopy in vivo in a genetically modified 3D-PLGA/nHAp scaffold for calvarial critical bone defect repair. PLGA/nHAp scaffolds were functionalized for the sustained delivery of a growth factor pdgf-b gene carrying lentiviral vectors (LV-pdgfb) in order to facilitate angiogenesis and to enhance bone regeneration. In a scaffold-implanted calvarial critical bone defect mouse model, the blood vessel areas (BVAs) in PHp scaffolds were significantly higher than in PH scaffolds. Additionally, the expression of pdgf-b and angiogenesis-related genes, vWF and VEGFR2, increased correspondingly. MicroCT analysis indicated that the new bone formation in the PHp group dramatically improved compared to the other groups. To our knowledge, this is the first time multiphoton microscopy was used in bone tissue-engineering to investigate angiogenesis in a 3D bio-degradable scaffold in vivo and in real-time.

Abstract
Cryopreservation of spermatogonial stem cells is considered as a useful procedure for preserving fertility in children with testis cancer. SSCs were isolated from testes mice, and then antioxidant was added to the freezing medium. The Bax expression level in antioxidant groups was significantly (P ≤ 0.05) lower than the control group and a significant rise of Bcl2 expression was detected in the antioxidant groups. ROS production with antioxidant was significantly lower compared with the control group. Cryopreservation with the addition of the antioxidants can help increase the number of SSCs and improve the quality and viability of these cells after cryopreservation.
