Abstract
Culture conditions regulate the process of pluripotency acquisition and self-renewal. This study aimed to analyse the influence of the in vitro environment on the induction of porcine induced pluripotent stem cell (piPSCs) differentiation into primordial germ cell-like cells (pPGCLCs). piPSC culture with different supplementation strategies (LIF, bFGF, or LIF plus bFGF) promoted heterogeneous phenotypic profiles. Continuous bFGF supplementation during piPSCs culture was beneficial to support a pluripotent state and the differentiation of piPSCs into pPGCLCs. The pPGCLCs were positive for the gene and protein expression of pluripotent and germinative markers. This study can provide a suitable in vitro model for use in translational studies and to help answer numerous remaining questions about germ cells.

Abstract
Background: Mesenchymal Stem Cells (MSCs) are present in almost all the tissues of the body and act as the backbone of the internal tissue homeostasis. Among their various characteristic features, immuno-modulatory and/ anti-inflammatory properties play an important role in therapeutics. Objective: The current topic focuses on the characterization and immuno-modulatory and/ anti-inflammatory properties of MSCs. To present and discuss the current status of MSCs immuno-modulatory properties. Methods: Available literature on MSCs properties and patents have been detailed, critically interpreted, and discussed based upon available literature. The main focus has been on their characteristic immuno-modulatory and anti-inflammatory properties though some of the basic characterization markers have also been detailed. The databases searched for the literature include PubMed, Med Line, PubMed Central, Science Direct and a few other scientific databases. Results: MSCs are present in a very limited concentration in the tissues, and as such their culture expansion becomes imperative. MSCs immuno-modulatory and anti-inflammatory roles are achieved through direct cell-cell contact and / by the release of certain factors. Such properties are controlled by micro-environment upon which currently very limited control can be exerted. Besides, further insights in the xeno-protein free culture media as against the fetal bovine serum is required. Conclusion: MSCs have been well-isolated, cultured and characterized from numerous tissues of the body. The majority of the studies have shown MSCs as immuno-compromised with immunomodulatory and / or anti-inflammatory properties except some of the latest studies that have failed to achieve the desired results and thus, demand further research. Further research is required in the area to translate the results into clinical application.

Generation of induced pluripotent stem cells from large domestic animals. Stem Cell Res Ther 2020; 11:247.

Abstract
BACKGROUND Induced pluripotent stem cells (iPSCs) have enormous potential in developmental biology studies and in cellular therapies. Although extensively studied and characterized in human and murine models, iPSCs from animals other than mice lack reproducible results. METHODS Herein, we describe the generation of robust iPSCs from equine and bovine cells through lentiviral transduction of murine or human transcription factors Oct4, Sox2, Klf4, and c-Myc and from human and murine cells using similar protocols, even when different supplementations were used. The iPSCs were analyzed regarding morphology, gene and protein expression of pluripotency factors, alkaline phosphatase detection, and spontaneous and induced differentiation. RESULTS Although embryonic-derived stem cells are yet not well characterized in domestic animals, generation of iPS cells from these species is possible through similar protocols used for mouse or human cells, enabling the use of pluripotent cells from large animals for basic or applied purposes. Herein, we also infer that bovine iPS (biPSCs) exhibit similarity to mouse iPSCs (miPSCs), whereas equine iPSs (eiPSCs) to human (hiPSCs). CONCLUSIONS The generation of reproducible protocols in different animal species will provide an informative tool for producing in vitro autologous pluripotent cells from domestic animals. These cells will create new opportunities in animal breeding through transgenic technology and will support a new era of translational medicine with large animal models.

Abstract
For over a century, 2D cell culture has been extensively used for all the different research fields. However, this in vitro system does not allow to reproduce the natural structures of the original tissue, causing several changes and, in most cases, the loss of cell-to-cell communications and cell-to-extracellular matrix interactions. Based on this, during the last years, novel 3D platforms, able to mimic the in vivo milieu, are being developed. The advantages of the use of 3D models are: the reduction of the gap between cell culture and physiological environment; imitation of the specific architecture; partially maintenance of the mechanical and biochemical cues of the original tissue. Currently, 3D systems are used in a broad range of studies, including the field of reproduction, where they have been applied to promote maturation of follicles and oocytes and embryo culture. Here, we review 2D and 3D cell culture methods, discussing advantages and limitations of these techniques. We report the fundamental mechanisms involved in cell ability to perceive and respond to mechanical cues and their role in transmitting signals to and between cells and in regulating intracellular signaling pathways. In particular, we focus on the main effectors of the Hippo pathway, Yes-associated protein (YAP) and WW domain-containing transcription regulator protein 1 (TAZ), describing their behavior and function in oocytes and embryos. Lastly, we provide an overall perspective of the most recent 3D technologies developed in the field of reproduction, describing how their use may revolutionize the understanding of cellular behavior and provide novel tools, useful in reproductive technologies and livestock production.

Abstract
Fusion of differentiated somatic cells with pluripotent stem cells can be used for cellular reprogramming, but the efficiency to obtain hybrid cells is extremely low. Here, we explored a novel cell fusion system, termed single-cell fusion, the efficiency was significantly improved verified by fusion of mouse embryonic stem cells (mESCs), comparing to traditional polyethylene glycol fusion. Then, we employed the optimized system to perform cell fusion of porcine embryonic fibroblasts (PEFs) and porcine pluripotent stem cells (pPSCs) with mESCs. The hybrid cells showed both red and green fluorescence and expressed species-specific genes of mouse and pig to evidence that the fusion was successful. The hybrid cells displayed characteristics similar with mESCs, including colony morphology, alkaline phosphatase positive and formation of embryoid body, and the expressions of core pluripotent factors OCT4, NANOG, and SOX2 of the pig were induced in the mESC/PEF hybrid cells. The results indicate PEFs and pPSCs could be reprogrammed by mESCs via the single-cell fusion. Taking advantage of the hybrid cells to investigate the signaling pathways depended on the pluripotency of pig, we suggest the transforming growth factor-β signaling pathways may play important roles. In summary, the single-cell fusion is highly efficient, and we believe in the future it will be widely used in the application and fundamental research.

Abstract
Stem cells are undifferentiated and self-renewable cells that present new possibilities for both regenerative medicine and the understanding of early mammalian development. Adult multipotent stem cells are already widely used worldwide in human and veterinary medicine, and their therapeutic signalling, particularly with respect to immunomodulation, and their trophic properties have been intensively studied. The derivation of embryonic stem cells (ESCs) from domestic species, however, has been challenging, and the poor results do not reflect the successes obtained in mouse and human experiments. More recently, the generation of induced pluripotent stem cells (iPSCs) via the forced expression of specific transcription factors has been demonstrated in domestic species and has introduced new potentials in regenerative medicine and reproductive science based upon the ability of these cells to differentiate into a variety of cells types in vitro. For example, iPSCs have been differentiated into primordial germ-like cells (PGC-like cells, PGCLs) and functional gametes in mice. The possibility of using iPSCs from domestic species for this purpose would contribute significantly to reproductive technologies, offering unprecedented opportunities to restore fertility, to preserve endangered species and to generate transgenic animals for biomedical applications. Therefore, this review aims to provide an updated overview of adult multipotent stem cells and to discuss new possibilities introduced by the generation of iPSCs in domestic animals, highlighting the possibility of generating gametes in vitro via PGCL induction.

Abstract
Properties like sustained multiplication and self-renewal, and homing and multilineage differentiation to undertake repair of the damaged tissues make stem cells the lifeline for any living system. Therefore, stem cell therapy is regarded to carry immense therapeutic potential. Though the dearth of understanding about the basic biological properties and pathways involved in therapeutic benefits currently limit the application of stem cells in humans as well as animals, there are innumerable reports that suggest clinical benefits of stem cell therapy in equine. Among various stem cell sources, currently adult mesenchymal stem cells (MSCs) are preferred for therapeutic application in horse owing to their easy availability, capacity to modulate inflammation, and promote healing. Also the cells carry very limited teratogenic risk compared to the pluripotent stem cells. Mesenchymal stem cells were earlier considered mainly for musculoskeletal tissues, but now may also be utilized in other diverse clinical problems in horse, and the results may be extrapolated even for human medicine. The current review highlights biological properties, sources, mechanisms, and potential therapeutic applications of stem cells in equine practice.

Abstract
Although the pig is considered an important model of human disease and an ideal animal for the preclinical testing of cell transplantation, the utility of this model has been hampered by a lack of genuine porcine embryonic stem cells. Here, we derived a porcine pluripotent stem cell (pPSC) line from day 5.5 blastocysts in a newly developed culture system based on MXV medium and a 5% oxygen atmosphere. The pPSCs had been passaged more than 75 times over two years, and the morphology of the colony was similar to that of human embryonic stem cells. Characterization and assessment showed that the pPSCs were alkaline phosphatase (AKP) positive, possessed normal karyotypes and expressed classic pluripotent markers, including OCT4, SOX2 and NANOG. In vitro differentiation through embryonic body formation and in vivo differentiation via teratoma formation in nude mice demonstrated that the pPSCs could differentiate into cells of the three germ layers. The pPSCs transfected with fuw-DsRed (pPSC-FDs) could be passaged with a stable expression of both DsRed and pluripotent markers. Notably, when pPSC-FDs were used as donor cells for somatic nuclear transfer, 11.52% of the reconstructed embryos developed into blastocysts, which was not significantly different from that of the reconstructed embryos derived from porcine embryonic fibroblasts. When pPSC-FDs were injected into day 4.5 blastocysts, they became involved in the in vitro embryonic development and contributed to the viscera of foetuses at day 50 of pregnancy as well as the developed placenta after the chimeric blastocysts were transferred into recipients. These findings indicated that the pPSCs were porcine pluripotent cells; that this would be a useful cell line for porcine genetic engineering and a valuable cell line for clarifying the molecular mechanism of pluripotency regulation in pigs.

Abstract
If one were to compare today's animal growth research to research from a mere 50 yr ago, one would see programs with few similarities. The evolution of this research from whole-animal through cell-based and finally molecular and genomic studies has been enhanced by the identification, isolation, and in vitro evaluation of adipose- and muscle-derived stem cells. This paper will highlight the struggles and the milestones that make this evolving area of research what it is today. The contribution of adipose and muscle stem cell research to development and growth, tissue regeneration, and final carcass composition are reviewed.

Abstract
Recent experiments demonstrated that forced expression of few critical genes drives conversion of a somatic into a pluripotent cell state. These induced pluripotent cells (iPS) were first generated from murine fibroblasts by Shinya Yamanaka's laboratory in 2006. By using retroviral vectors to express combinations of stemness genes, they identified Oct4, Sox2, Krueppel-like factor 4 and c-Myc as essential factors for reprogramming of somatic cells. Subsequent experiments applied this technology to human and rat fibroblasts, as well as other cell types and several groups showed that iPS can be generated by an even smaller number of transcription factors. The efficiency of conversion and maintenance of a pluripotent state can be supported by small molecules, such as valproic acid and specific pharmacological inhibitors. This technology is a milestone for a basic understanding of cell potency, cell fate and pathogenesis, as well as for development of cell therapies and potential applications in animal breeding.

Abstract
Porcine transgenic cloning has potential applications for improving production traits and for biomedical research purposes. To produce a transgenic clone, kidney fibroblasts from a newborn Guangxi Bama mini-pig were isolated, cultured, and then transfected with red and green fluorescent protein genes using lipofectamine for nuclear transfer. The results of the present study show that the kidney fibroblasts exhibited excellent proliferative capacity and clone-like morphology, and were adequate for generation of somatic cell nuclear transfer (SCNT)-derived embryos, which was confirmed by their cleavage activity and blastocyst formation rate of 70.3% and 7.9%, respectively. Cells transfected with red fluorescent protein genes could be passed more than 35 times. Transgenic embryos cloned with fluorescent or blind enucleation methods were not significantly different with respect to cleavage rates (92.5% vs. 86.8%, p > 0.05) and blastocyst-morula rates (26.9% vs. 34.0%, p > 0.05), but were significantly different with respect to blastocyst rates (3.0% vs. 13.2%, p < 0.05). Cleavage (75.3%, 78.5% vs. 78.0%, p > 0.05), blastocyst (14.1%, 16.1% vs. 23.1%, p > 0.05) and morula/blastocyst rates (43.5%, 47.0% vs. 57.6%, p > 0.05) were not significantly different between the groups of transgenic cloned embryos, cloned embryos, and parthenogenetic embryos. This indicates that long-time screening by G418 caused no significant damage to kidney fibroblasts. Thus, kidney fibroblasts represent a promising new source for transgenic SCNT, and this work lays the foundation for the production of genetically transformed cloned Guangxi Bama mini-pigs.

Abstract
Endogenous retroviruses (ERVs) are remnants of retroviral germ line infections and have been identified in all mammals investigated so far. Although the majority of ERVs are degenerated, some mammalian species, such as mice and pigs, carry replication-competent ERVs capable of forming infectious viral particles. In mice, ERVs are silenced by DNA methylation and histone modifications and some exogenous retroviruses were shown to be transcriptionally repressed after integration by a primer-binding site (PBS) targeting mechanism. However, epigenetic repression of porcine ERVs (PERVs) has remained largely unexplored so far. In this study, we screened the pig genome for PERVs using LTRharvest, a tool for de novo detection of ERVs, and investigated various aspects of epigenetic repression of three unrelated PERV families. We found that these PERV families are differentially up- or downregulated upon chemical inhibition of DNA methylation and histone deacetylation in cultured porcine cells. Furthermore, chromatin immunoprecipitation analysis revealed repressive histone methylation marks at PERV loci in primary porcine embryonic germ cells and immortalized embryonic kidney cells. PERV elements belonging to the PERV-γ1 family, which is the only known PERV family that has remained active up to the present, were marked by significantly higher levels of histone methylations than PERV-γ2 and PERV-β3 proviruses. Finally, we tested three PERV-associated PBS sequences for repression activity in murine and porcine cells using retroviral transduction experiments and showed that none of these PBS sequences induced immediate transcriptional silencing in the tested primary porcine cells.

Abstract
Huge amounts of work have been dedicated to the establishment of embryonic stem cell lines from farm animal species since the successful isolation of embryonic stem cells from the mouse and from the human. However, no conclusive results have been obtained so far, and validated lines have yet to be established in domestic animals. Many limiting factors have been suggested and need to be studied further to isolate truly pluripotent cell lines from livestock. In this review, we will discuss the difficulties in deriving and maintaining embryonic stem cell lines from farm animal embryos and how can this lack of success be explained. We will summarize results obtained in our laboratory regarding derivation of pluripotent cells in the pigs. Problems related to the identification of standard methods for derivation, maintenance and characterization of cell lines will also be examined. We will focus our attention on the need for appropriate stemness-related marker molecules that can be used to reliably investigate pluripotency in domestic species. Finally, we will review data presently available on functional key pluripotency-maintaining pathways in farm animals.

Abstract
Pluripotent stem cells are the focus of an extremely active field of investigation that is bringing new light on our understanding of the mechanisms that control pluripotency and differentiation. Rodent and primates are the only species where true, or bona fide, pluripotent stem cells have been derived. The attempts to derive pluripotent stem cells from domestic ungulates have been going on for more than 20 years with little progress. Cell lines from these species present a series of limitations that have precluded their use for both basic and clinically oriented studies. However, in the last 3 years, some substantial progress have been made making the currently available ungulate pluripotent stem cells closest than ever before to their human and mouse counterpart. This result has been achieved through both conceptual and technical progress that will be illustrated and discussed in this review.

Abstract
The domestic pig is an important large animal model for preclinical testing of novel cell therapies. Recently, we produced pluripotency reporter pigs in which the Oct4 promoter drives expression of the enhanced green fluorescent protein (EGFP). Here, we reprogrammed Oct4-EGFP fibroblasts employing the nonviral Sleeping Beauty transposon system to deliver the reprogramming factors Oct4, Sox2, Klf4, and cMyc. Successful reprogramming to a pluripotent state was indicated by changes in cell morphology and reactivation of the Oct4-EGFP reporter. The transposon-reprogrammed induced pluripotent stem (iPS) cells showed long-term proliferation in vitro over >40 passages, expressed transcription factors typical of embryonic stem cells, including OCT4, NANOG, SOX2, REX1, ESRRB, DPPA5, and UTF1 and surface markers of pluripotency, including SSEA-1 and TRA-1-60. In vitro differentiation resulted in derivatives of the 3 germ layers. Upon injection of putative iPS cells under the skin of immunodeficient mice, we observed teratomas in 3 of 6 cases. These results form the basis for in-depth studies toward the derivation of porcine iPS cells, which hold great promise for preclinical testing of novel cell therapies in the pig model.

Abstract
Recombinant adeno-associated virus (rAAV) vectors have been extensively used for experimental gene therapy of inherited human diseases. Several advantages, such as simple vector construction, high targeting frequency by homologous recombination, and applicability to many cell types, make rAAV an attractive approach for targeted genome editing. Combined with cloning by somatic cell nuclear transfer (SCNT), this technology has recently been successfully adapted to generate gene-targeted pigs as models for cystic fibrosis, hereditary tyrosinemia type 1, and breast cancer. This review summarizes the development of rAAV for targeted genome editing in mammalian cells and provides strategies for enhancing the rAAV-mediated targeting frequency by homologous recombination. We discuss current development and application of the rAAV vectors for targeted genome editing in porcine primary fibroblasts, which are subsequently used as donor cells for SCNT to generate cloned genetically designed pigs and provide positive perspectives for the generation of gene-targeted pigs with rAAV in the future.

Abstract
The pig represents an ideal large-animal model, intermediate between rodents and humans, for the preclinical assessment of emerging cell therapies. As no validated pig embryonic stem (pES) cell lines have been derived so far, pig induced pluripotent stem cells (piPSCs) should offer an alternative source of undifferentiated cells to advance regenerative medicine research from bench to clinical trial. We report here for the first time the derivation of piPSCs from adult fibroblast with only three transcription factors: Sox2 (sex determining region Y-box 2), Klf4 (Krüppel-like factor 4), and c-Myc (avian myelocytomatosis viral oncogene homolog). We have been able to demonstrate that exogenous Pou5f1 (POU domain class 5 transcription factor 1; abbreviated as Octamer-4: Oct4) is dispensable to achieve and maintain pluripotency in the generation of piPSCs. To the best of our knowledge, this is also the first report of somatic reprogramming in any species without the overexpression, either directly or indirectly, of Oct4. Moreover, we were able to generate piPSCs without the use of feeder cells, approaching thus xeno-free conditions. Our work paves the way for the derivation of clinical grade piPSCs for regenerative medicine.

Abstract
Pluripotent cells are unique because of their ability to differentiate into the cell lineages forming the entire organism. True pluripotent stem cells with germ line contribution have been reported for mice and rats. Human pluripotent cells share numerous features of pluripotentiality, but confirmation of their in vivo capacity for germ line contribution is impossible due to ethical and legal restrictions. Progress toward derivation of embryonic stem cells from domestic species has been made, but the derived cells were not able to produce germ line chimeras and thus are termed embryonic stem-like cells. However, domestic animals, in particular the domestic pig (Sus scrofa), are excellent large animals models, in which the clinical potential of stem cell therapies can be studied. Reprogramming technologies for somatic cells, including somatic cell nuclear transfer, cell fusion, in vitro culture in the presence of cell extracts, in vitro conversion of adult unipotent spermatogonial stem cells into germ line derived pluripotent stem cells, and transduction with reprogramming factors have been developed with the goal of obtaining pluripotent, germ line competent stem cells from domestic animals. This review summarizes the present state of the art in the derivation and maintenance of pluripotent stem cells in domestic animals.

Abstract
It has been 30 years since the first transgenic mouse was generated and 26 years since the first example of transferring the technology to livestock was published. While there was tremendous optimism in those initial years, with most convinced that genetically modified animals would play a significant role in agricultural production, that has not come to be. So at first sight one could conclude that this technology has, to a large extent, failed. On the contrary, it is believed that it has succeeded beyond our original expectations, and we are now at what is perhaps the most exciting time in the development and implementation of these technologies. The original goals, however, have drastically changed and it is now biomedical applications that are playing a central role in pushing both technical and scientific developments. The combination of advances in somatic cell nuclear transfer, the development of induced pluripotent stem cells and the completion of the sequencing of most livestock genomes ensures a bright and exciting future for this field, not only in livestock but also in companion animal species.

Abstract
Reprogramming of pig somatic cells to induced pluripotent stem cells provides a tremendous advance in the field of regenerative medicine since the pig represents an ideal large animal model for the preclinical testing of emerging cell therapies. However, the current generation of pig-induced pluripotent stem cells (piPSCs) require the use of time-consuming and laborious retroviral or lentiviral transduction approaches, in order to ectopically express the pluripotency-associated transcription factors Oct4, Sox2, Klf4 and c-Myc, in the presence of feeder cells. Here, we describe a simple method to produce piPSC with a single transfection of a CAG-driven polycistronic plasmid expressing Oct4, Sox2, Klf4, c-Myc and a green fluorescent protein (GFP) reporter gene, in gelatine-coated plates, with or without feeder cells. In our system, the derivation of piPSCs from adult pig ear fibroblasts on a gelatine coating showed a higher efficiency and rate of reprogramming when compared with three consecutive retroviral transductions of a similar polycistronic construct. Our piPSCs expressed the classical embryonic stem cell markers, exhibit a stable karyotype and formed teratomas. Moreover, we also developed a simple method to generate in vitro spontaneous beating cardiomiocyte-like cells from piPSCs. Overall, our preliminary results set the bases for the massive production of xeno-free and integration-free piPSCs and provide a powerful tool for the preclinical application of iPSC technology in a large animal setting.

Abstract
Cartilage and tendon injuries are a significant source of animal wastage and financial loss within the horse-racing industry. Moreover, both cartilage and tendon have limited intrinsic capacity for self-repair, and the functionally inferior tissue produced within a lesion may reduce performance and increase the risk of reinjury. Stem cells offer tremendous potential for accelerating and improving tissue healing, and adult mesenchymal stem cells (MSCs) are already used to treat cartilage and tendon injuries in horses. However, MSCs are scarce in the bone marrow isolates used, have limited potential for proliferation and differentiation in vitro, and do not appear to noticeably improve long-term functional repair. Embryonic stem cells (ESCs) or induced pluripotent stem (iPS) cells could overcome many of the limitations and be used to generate tissues of value for equine regenerative medicine. To date, six lines of putative ESCs have been described in the horse. All expressed stem cell-associated markers and exhibited longevity and pluripotency in vitro, but none have been proven to exhibit pluripotency in vivo. Moreover, it is becoming clear that the markers used to characterize the putative ESCs were inadequate, primarily because studies in domestic species have revealed that they are not specific to ESCs or the pluripotent inner cell mass, but also because the function of most in the maintenance of pluripotency is not known. Future derivation and validation of equine embryonic or other pluripotent stem cells would benefit greatly from a reliable panel of molecular markers specific to pluripotent cells of the developing horse embryo.
