Abstract
Sus scrofa domesticus (pig) has served as a superb large mammalian model for biomedical studies because of its comparable physiology and organ size to humans. The derivation of transgene-free porcine induced pluripotent stem cells (PiPSCs) will, therefore, benefit the development of porcine-specific models for regenerative biology and its medical applications. In the past, this effort has been hampered by a lack of understanding of the signaling milieu that stabilizes the porcine pluripotent state in vitro. Here, we report that transgene-free PiPSCs can be efficiently derived from porcine fibroblasts by episomal vectors along with microRNA-302/367 using optimized protocols tailored for this species. PiPSCs can be differentiated into derivatives representing the primary germ layers in vitro and can form teratomas in immunocompromised mice. Furthermore, the transgene-free PiPSCs preserve intrinsic species-specific developmental timing in culture, known as developmental allochrony. This is demonstrated by establishing a porcine in vitro segmentation clock model that, for the first time, displays a specific periodicity at ∼3.7 h, a timescale recapitulating in vivo porcine somitogenesis. We conclude that the transgene-free PiPSCs can serve as a powerful tool for modeling development and disease and developing transplantation strategies. We also anticipate that they will provide insights into conserved and unique features on the regulations of mammalian pluripotency and developmental timing mechanisms.

Abstract
The number of endangered avian-related species increase in Japan recently. The application of new technologies, such as induced pluripotent stem cells (iPSCs), may contribute to the recovery of the decreasing numbers of endangered animals and conservation of genetic resources. We established novel iPSCs from three endangered avian species (Okinawa rail, Japanese ptarmigan, and Blakiston’s fish owl) with seven reprogramming factors (M3O, Sox2, Klf4, c-Myc, Nanog, Lin28, and Klf2). The iPSCs are pluripotency markers and express pluripotency-related genes and differentiated into three germ layers in vivo and in vitro. These three endangered avian iPSCs displayed different cellular characteristics even though the same reprogramming factors use. Japanese ptarmigan-derived iPSCs have different biological characteristics from those observed in other avian-derived iPSCs. Japanese ptarmigan iPSCs contributed to chimeras part in chicken embryos. To the best of our knowledge, our findings provide the first evidence of the potential value of iPSCs as a resource for endangered avian species conservation. iPSCs from three endangered avian species (including Okinawa rail, Japanese ptarmigan, and Blakiston’s fish owl) are developed and characterized as a potential resource for their conservation.

Abstract
Miniature pigs are an ideal animal model for translational research to evaluate stem cell therapies and regenerative applications. While the derivation of induced pluripotent stem cells (iPSCs) from miniature pigs has been demonstrated, there is still a lack of a reliable method to generate and maintain miniature pig iPSCs. In this study, we derived iPSCs from fibroblasts of Wisconsin miniature swine (WMS), Yucatan miniature swine (YMS), and Göttingen minipigs (GM) using our culture medium. By comparing cells of the different pig breeds, we found that YMS fibroblasts were more efficiently reprogrammed into iPSCs, forming colonies with well-defined borders, than WMS and GM fibroblasts. We also demonstrated that YMS iPSC lines with a normal pig karyotype gave rise to cells of the three germ layers in vitro and in vivo. Mesenchymal stromal cells expressing phenotypic characteristics were derived from established iPSC lines as an example of potential applications. In addition, we found that the expression level of the switch/sucrose nonfermentable component BAF60A regulated by STAT3 signaling determined the efficiency of pig iPSC generation. The findings of this study provide insight into the underlying mechanism controlling the reprogramming efficiency of miniature pig cells to develop a viable strategy to enhance the generation of iPSCs for biomedical research.

Exogenous LIN28 Is Required for the Maintenance of Self-Renewal and Pluripotency in Presumptive Porcine-Induced Pluripotent Stem Cells. Front Cell Dev Biol 2021; 9:709286.

Abstract
Porcine species have been used in preclinical transplantation models for assessing the efficiency and safety of transplants before their application in human trials. Porcine-induced pluripotent stem cells (piPSCs) are traditionally established using four transcription factors (4TF): OCT4, SOX2, KLF4, and C-MYC. However, the inefficiencies in the reprogramming of piPSCs and the maintenance of their self-renewal and pluripotency remain challenges to be resolved. LIN28 was demonstrated to play a vital role in the induction of pluripotency in humans. To investigate whether this factor is similarly required by piPSCs, the effects of adding LIN28 to the 4TF induction method (5F approach) on the efficiency of piPSC reprogramming and maintenance of self-renewal and pluripotency were examined. Using a retroviral vector, porcine fetal fibroblasts were transfected with human OCT4, SOX2, KLF4, and C-MYC with or without LIN28. The colony morphology and chromosomal stability of these piPSC lines were examined and their pluripotency properties were characterized by investigating both their expression of pluripotency-associated genes and proteins and in vitro and in vivo differentiation capabilities. Alkaline phosphatase assay revealed the reprogramming efficiencies to be 0.33 and 0.17% for the 4TF and 5TF approaches, respectively, but the maintenance of self-renewal and pluripotency until passage 40 was 6.67 and 100%, respectively. Most of the 4TF-piPSC colonies were flat in shape, showed weak positivity for alkaline phosphatase, and expressed a significantly high level of SSEA-4 protein, except for one cell line (VSMUi001-A) whose properties were similar to those of the 5TF-piPSCs; that is, tightly packed and dome-like in shape, markedly positive for alkaline phosphatase, and expressing endogenous pluripotency genes (pOCT4, pSOX2, pNANOG, and pLIN28), significantly high levels of pluripotent proteins (OCT4, SOX2, NANOG, LIN28, and SSEA-1), and a significantly low level of SSEA-4 protein. VSMUi001-A and all 5F-piPSC lines formed embryoid bodies, underwent spontaneous cardiogenic differentiation with cardiac beating, expressed cardiomyocyte markers, and developed teratomas. In conclusion, in addition to the 4TF, LIN28 is required for the effective induction of piPSCs and the maintenance of their long-term self-renewal and pluripotency toward the development of all germ layers. These piPSCs have the potential applicability for veterinary science.

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
We previously reported the successful establishment of multiple immortalized cell lines that preserved the original nature of the primary cells via co-expression of R24C mutant cyclin-dependent kinase 4 (CDK4R24C), Cyclin D1, and telomerase reverse transcriptase (TERT). However, as these genes are kind of oncogenes, tools to control their expression levels are favorable. In this study, we describe a new polycistronic lentiviral vector expressing proliferation factors, CDK4R24C and Cyclin D1 along with enhanced green fluorescence protein (EGFP) under the control of doxycycline (Dox)-dependent transactivator (rtTA) and tetracycline response element (TRE). By introducing the Dox-inducible lentiviral vector into human airway epithelial cells, we established a novel human airway epithelial cell line harboring polycistronic Dox-inducible CDK4R24C and Cyclin D1, referred to as Tet-on K4D cells. We showed that the cell growth of Tet-on K4D cells could be controlled by Dox. Furthermore, expression of K4D genes and rtTA gene can be independently monitored by fluorescent imaging. Cultured airway epithelial cells are useful as a tool for studying the pathogenesis of lung disorders. Altogether, our established human airway epithelial cells could be used for a variety of studies such as lung pathology and biology underlying the differentiation process to form the complex pseudostratified multicellular layers.

Abstract
Past researches have shown that pluripotency maintenance of naive and primed-state pluripotent stem cells (PSCs) depends on different signaling pathways, and naive-state PSCs possess the ability to produce chimeras when they are introduced into a blastocyst. Considering porcine is an attractive model for preclinical studies, many researches about pig induced pluripotent stem cells (piPSCs) have been reported. Some cytokines and small molecule compounds could transform primed piPSCs into naive state. However, there are no suitable culture conditions for generation of naive-state piPSCs with high efficiency; other small molecule compounds need further exploration. In this study, we investigated whether p38 MAPK and JNK signal pathway inhibitor SB203580 and SP600125 could be of benefit for acquiring naive-state piPSCs. By comparing reprogramming efficiencies under conditions of different donor cells and culture environment, we found that porcine bone marrow mesenchymal stem cells (PBMSCs) have higher efficiency on piPSC induction, and the culture condition of CHIR99021+PD0325901(2i)+Lif+bFGF is more suitable for subculturing of piPSCs. Our results also indicate that SB203580 and SP600125 could promote reprogramming of PBMSCs into naive-like state piPSCs. These results provide guidance for choosing donor cells, culture conditions, and research of different state iPSCs during the process of reprogramming pig somatic cells.

Abstract
The development of the induced pluripotent stem cells (iPSCs) technology has revolutionized the world on the establishment of pluripotent stem cells (PSCs) across a great variety of animal species. Generation of iPSCs from domesticated animals would provide unrestricted cell resources for the study of embryonic development and cell differentiation of these species, for screening and establishing desired traits for sustainable agricultural production, and as veterinary and preclinical therapeutic tools for animal and human diseases. Induced PSCs from domesticated animals thus harbor enormous scientific, economical, and societal values. Although much progress has been made toward the generation of PSCs from these species, major obstacles remain precluding the exclamation of the establishment of bona fide iPSCs. The most prominent of them remain the inability of these cells to silence exogenous reprogramming factors, the obvious reliance on exogenous factors for their self-renewal, and the restricted development potential in vivo. In this review, we summarize the history and current progress in domestic farm animal iPSC generation, with a focus on swine, ruminants (cattle, ovine, and caprine), horses, and avian species (quails and chickens). We also discuss the problems associated with the farm animal iPSCs and potential future directions toward the complete reprogramming of somatic cells from farm animals.

Abstract
Induced pluripotent stem cells (iPSCs) are undifferentiated stem cells characterized by the ability to differentiate into any cell type in the body. iPSCs are a relatively new and rapidly developing technology in many fields of biology, including developmental anatomy and physiology, pathology, and toxicology. These cells have great potential in research as they are self-renewing and pluripotent with minimal ethical concerns. Protocols for their production have been developed for many domestic animal species, which have since been used to further our knowledge in the progression and treatment of diseases. This research is valuable both for veterinary medicine as well as for the prospect of translation to human medicine. Safety, cost, and feasibility are potential barriers for this technology that must be considered before widespread clinical adoption. This review will analyze the literature pertaining to iPSCs derived from various domestic species with a focus on iPSC production and characterization, applications for tissue and disease research, and applications for disease treatment.

Abstract
We investigated whether sequential reprogramming via porcine induced pluripotent stem cells (piPSCs) or exposure to oocyte cytoplasm following nuclear transfer could generate nuclear transfer-derived ESCs (piPSCs-ntESCs). Nuclear transfer embryos were reconstructed with piPSCs possessing a ZsGreen fluorescent marker for expression of exogenous Nanog and Lin28. Reconstructed oocytes developed to morphologically normal 8-cell/morulae (35/93, 37.6%) and blastocysts (12/93, 12.9%). Although most green fluorescent protein-positive blastocysts showed efficient outgrowth (8/10, 80%), none formed primary colonies and all cultures degenerated. Conversely, 15% of fluorescent positive 8-cell/morula stage embryos showed outgrowth (6/40), with three forming primary colonies (7.5%). All three were expanded and maintained as piPSC-ntESC lines. These cell lines expressed stem cell marker genes and proteins. Despite inactivation of one X chromosome, all piPSC-ntESC lines formed teratomas comprising derivatives from all three embryonic germ layers. Strong SSEA1, 3, and 4 expression was detected at the 8-cell/morula stage in embryos reconstructed from both piPSCs and porcine embryonic fibroblasts (PEFs). SSEA3 was notably absent from IVF controls at pre-implantation embryo stages. Finally, we attempted to establish ntESCs from 8-cell/morulae reconstructed with PEFs using the same culture conditions as those for piPSC-ntESC derivation. Although eight primary colonies arose from 107 embryos (7.5%), they all degenerated after the first passage culture. Early and sustained expression of key reprogramming regulatory factors may be critical for pluripotent stem cell derivation to derive piPSC-ntESCs from 8-cell/morula stages, while the expression of SSEAs may be involved in the initial stem cell colony formation phases.

Abstract
Androgenetic alopecia (AGA) is the most common type of hair loss, and is mainly caused by the biological effects of testosterone on dermal papilla cells (DPCs). In vitro culturing of DPCs might be a useful tool for the screening of target molecule of AGA. However, primary DPCs cannot continuously proliferate owing to cellular senescence and cell culture stress. In this study, we introduced mutant cyclin-dependent kinase 4 (CDK4), Cyclin D1, and telomerase reverse transcriptase (TERT) into DPCs. We confirmed protein expression of CDK4 and Cyclin D1, and enzymatic activity of TERT. Furthermore, we found the established cell line was free from cellular senescence. We also introduced the androgen receptor gene using a recombinant retrovirus, to compensate the transcriptional suppressed endogenous androgen receptor in the process of cell proliferation. Furthermore, we detected the efficient nuclear translocation of androgen receptor into the nucleus after the treatment of dihydrotestosterone, indicating the functionality of our introduced receptor. Our established cell line is a useful tool to identify the downstream signaling pathway, which activated by the testosterone.

Abstract
The lysine demethylases KDM5B and KDM5C are highly, but transiently, expressed in porcine embryos around the genome activation stage. Attenuation of KDM5B and KDM5C mRNA hampered embryo development to the blastocyst stage in fertilized, parthenogenetically activated and nuclear transfer embryos. While KDM5B attenuation increased H3K4me2-3 levels on D3 embryos and H3K4me1-2-3 on D5 embryos, KDM5C attenuation increased H3K9me1 on D3 embryos, and H3K9me1 and H3K4me1 on D5 embryos. The relative mRNA abundance of EIF1AX and EIF2A on D3 embryos, and the proportion of D4 embryos presenting a fluorescent signal for uridine incorporation were severely reduced in both KDM5B- and KDM5C-attenuated compared to control embryos, which indicate a delay in the initiation of the embryo transcriptional activity. Moreover, KDM5B and KDM5C attenuation affected DNA damage response and increased DNA double-strand breaks (DSBs), and decreased development of UV-irradiated embryos. Findings from this study revealed that both KDM5B and KDM5C are important regulators of early development in porcine embryos as their attenuation altered H3K4 and H3K9 methylation patterns, perturbed embryo genome activation, and decreased DNA damage repair capacity.

A cytokine screen using CRISPR-Cas9 knock-in reporter pig iPS cells reveals that Activin A regulates NANOG. Stem Cell Res Ther 2020; 11:67. [PMID: 32070424 PMCID: PMC7029561 DOI: 10.1186/s13287-020-1588-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 01/09/2020] [Accepted: 02/05/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND NANOG functions as the gateway for the generation of pluripotent stem cells (PSCs) in mice and humans. NANOG is a transcription factor highly expressed in pig pre-implantation embryos, indicating that it is a conserved pluripotency-associated factor. However, pig NANOG reporter PSCs have yet to be established, and the regulation of pluripotency by NANOG is not fully understood in this animal. METHODS In this study, pig NANOG tdTomato knock-in reporter positive PC-iPS cells were established using CRISPR/Cas9. The resulting cell line was treated with several cytokines and their corresponding inhibitors to identify pathways that regulate NANOG expression. The pathways examined were LIF (leukemia inhibitory factor)/IL6 (interleukin 6)-STAT3, FGF (fibroblast growth factor)/ERK, IGF1 (insulin-like growth factor 1)/PIP3 (phosphoinositide 3-kinase)-AKT, Activin A/SMAD, and BMP4 (bone morphogenetic proteins)/SMAD. RESULTS Our experiments showed that the Activin A/SMAD pathway is directly associated with activation of NANOG expression in the pig, as is also the case in mice and humans. Activin A directly regulates the expression of pig NANOG via SMAD2/3; inhibition of this pathway by SB431542 resulted in inhibition of NANOG expression. CONCLUSIONS Our results show that Activin A plays an important regulatory role in NANOG-mediated pluripotency in pig iPS cells. Activin A treatment may be therefore an effective method for de novo derivation of authentic embryonic stem cells (ESCs) from pig pre-implantation embryos.

Abstract
Induced pluripotent stem cell (iPSC) technology offers a practically infinite and ethically acceptable source to obtain a variety of somatic cells. Coupled with the biotechnologies of cell therapy or tissue engineering, iPSC technology will enormously contribute to human regenerative medicine. Before clinical application, such human iPSC (hiPSC)-based therapies should be assessed using large animal models that more closely match biological or biomechanical properties of human patients. Therefore, it is critical to generate large animal iPSCs, obtain their iPSC-derived somatic cells, and preclinically evaluate their therapeutic efficacy and safety in large animals. During the past decade, the establishment of iPSC lines of a series of large animal species has been documented, and the acquisition and preclinical evaluation of iPSC-derived somatic cells has also been reported. Despite this progress, significant obstacles, such as obtaining or preserving the bona fide pluripotency of large animal iPSCs, have been encountered. Simultaneously, studies of large animal iPSCs have been overlooked in comparison with those of mouse and hiPSCs, and this field deserves more attention and support due to its important preclinical relevance. Herein, this review will focus on the large animal models of pigs, dogs, horses, and sheep/goats, and summarize current progress, challenges, and potential future directions of research on large animal iPSCs.

Abstract
Background Pigs have emerged as one of the most popular large animal models in biomedical research, which in many cases is considered as a superior choice over rodent models. In addition, transplantation studies using pig pluripotent stem (PS) cell derivatives may serve as a testbed for safety and efficacy prior to human trials. Recently, it has been shown that mouse and human PS cells cultured in LCDM (recombinant human LIF, CHIR 99021, (S)-(+)-dimethindene maleate, minocycline hydrochloride) medium exhibited extended developmental potential (designated as extended pluripotent stem cells, or EPS cells), which could generate both embryonic and extraembryonic tissues in chimeric mouse conceptus. Whether stable pig induced pluripotent stem (iPS) cells can be generated in LCDM medium and their chimeric competency remains unknown. Methods iPS cells were generated by infecting pig pericytes (PC) and embryonic fibroblasts (PEFs) with a retroviral vector encoding Oct4, Sox2, Klf4, and cMyc reprogramming factors and subsequently cultured in a modified LCDM medium. The pluripotency of PC-iPS and PEF-iPS cells was characterized by examining the expression of pluripotency-related transcription factors and surface markers, transcriptome analysis, and in vitro and in vivo differentiation capabilities. Chimeric contribution of PC-iPS cells to mouse and pig conceptus was also evaluated with fluorescence microscopy, flow cytometry, and PCR analysis. Results In this study, using a modified version of the LCDM medium, we successfully generated iPS cells from both PCs and PEFs. Both PC-iPS and PEF-iPS cells maintained the stable “dome-shaped” morphology and genome stability after long-term culture. The immunocytochemistry analyses revealed that both PC-iPS and PEF-iPS cells expressed OCT4, SOX2, and SALL4, but only PC-iPS cells expressed NANOG and TRA-1-81 (faint). PC-iPS and PEF-iPS cells could be differentiated into cell derivatives of all three primary germ layers in vitro. The transcriptome analysis showed that PEF-iPS and PC-iPS cells clustered with pig ICM, Heatmap and volcano plot showed that there were 1475 differentially expressed genes (DEGs) between PC-iPS and PEF-iPS cells (adjusted p value < 0.1), and the numbers of upregulated genes and downregulated genes in PC-iPS cells were 755 and 720, respectively. Upregulated genes were enriched with GO terms including regulation of stem cell differentiation, proliferation, development, and maintenance. And KEGG pathway enrichment in upregulated genes revealed Wnt, Jak-STAT, TGF-β, P53, and MAPK stem cell signaling pathways. Fluorescence microscopy and genomic PCR analyses using pig mtDNA-specific and GFP primers showed that the PC-iPS cell derivatives could be detected in both mouse and pig pre-implantation blastocysts and post-implantation conceptuses. Quantitative analysis via flow cytometry revealed that the chimeric contribution of pig PC-iPS cells in mouse conceptus was up to 0.04%. Conclusions Our findings demonstrate that stable iPS cells could be generated in LCDM medium, which could give rise to both embryonic and extraembryonic cells in vivo. However, the efficiency and level of chimeric contribution of pig LCDM-iPS cells were found low.

Abstract
Understanding essential signaling network requirements and making appropriate adjustments in culture conditions are crucial if porcine pluripotent stem cells (PSC) are to achieve their full potential. Here, we first used two protein factors (LIF and FGF2) and kinase inhibitor combinations in attempts to convert primed type lentiviral-reprogrammed porcine induced PSC (Lv-piPSC) into naïve-like state and developed a medium called FL6i. In addition to FGF2 and LIF, this medium contained inhibitors of MAPK14, MAPK8, TGFB1, MAP2K1, GSK3A and BMP. Crucially, the usual TGFB1 and BMP4 protein components of many stem cell media were replaced in FL6i with inhibitors of TGFB1 and BMP. With this medium, Lv-piPSC were readily transformed from their original primed state into cells that formed colonies with typical features of naïve-state stem cells. The FL6i medium also assisted generation of naïve-type piPSC lines from porcine embryonic fibroblasts with non-integrating episomal plasmids (Epi-piPSC). These lines, despite retaining variable amounts of vector DNA, expressed higher endogenous pPOU5F1 and pSOX2 than Lv-piPSC. They have been cultured without obvious morphological change for >45 passages and retained pluripotent phenotypes in terms of upregulation of genes associated with pluripotency, low expression of genes linked to emergence of somatic cell lineages, and ability to generate well differentiated teratomas in immune-compromised mice. FL6i conditions, therefore, appear to support elevated pluripotent phenotypes. However, FL6i was less able to support the generation of embryonic stem cells from porcine blastocysts. Although colonies with dome-shaped morphologies were evident and the cells had some gene expression features linked to pluripotency, the phenotypes were ultimately not stable. Pathway analysis derived from RNAseq data performed on the various cell lines generated in this study suggest the benefits of employing the FL6i medium on porcine cells reside in its ability to minimize TGFB1 and BMP signaling, which would otherwise de-stabilize the stem cell state.

Abstract
Pigs are important, both for agriculture and as animal models for human diseases. However, due to the lack of embryonic stem cells, the possibility of genetic modification is quite limited. To overcome this limitation, induced pluripotent stem (iPS) cells have been derived from pigs. Despite the public availability of a large number of expression datasets from mice, rats, and primates-derived iPS cells, the expression profile of pig-derived iPS cells is quite limited. Furthermore, there is no dataset focused on the profiling of pig-derived iPS cell with six reprogramming factors (Oct3/4, Sox2, Klf4, c-Myc, Lin28, and Nanog). Here, we used Illumina RNA sequencing platform to characterize the mRNA expression of four-factor derived and six-factor derived pig iPS cells. We observed that the expression levels of whole genes in our established six factors derived iPS cells and parent fibroblast, and compared with that of iPS cells with four factors in public database. These data are valuable in understanding species difference in the reprogramming process of stem cells, and could help identify the key regulating genes involved in the process.

Abstract
Although immortalized cultured cells are useful for various functional assays or transcriptome analysis, highly efficient and reproducible immortalization methods have not been developed in avian-derived cells. We introduced the simian virus 40 T antigen (SV40T) and human papillomavirus (HPV)-E6E7 to chick and Okinawa rail (endangered species)derived fibroblast. As a result, neither the SV40T nor E6E7 genes could induce avian cell immortality. Accordingly, we attempted to use a recently developed immortalization method, which involved the coexpression of mutant cyclin-dependent kinase 4 (CDK4), Cyclin D, and TERT (K4DT method) in these avian cells. Although the K4DT method could not efficiently induce the efficient immortalization in mass cell population, cellular division until the senescence was significantly extended by K4DT, we succeeded to obtain the immortalized avian cells (chick K4DT: one clone, Okinawa rail K4DT: three clones, Okinawa rail K4DT + telomerase RNA component: one clone) with K4DT expression. We conclude that K4DT expression is used to extend the cell division and immortalization of avian-derived cells.

Preserving self-renewal of porcine pluripotent stem cells in serum-free 3i culture condition and independent of LIF and b-FGF cytokines. Cell Death Discov 2018.

Abstract
Derivation of bona fide porcine pluripotent stem cells is still a critical issue because porcine embryonic stem cells (ESCs) are not available yet, and most of the culture conditions to maintain porcine induced pluripotent stem cells (piPSCs) are based on conditions for mouse and human iPS cells. In this study, we generated a doxycycline-inducible porcine iPS cell line (DOX-iPSCs) and used it to screen the optimal culture condition to sustain the self-renewal of piPSCs. We found that LIF and b-FGF were required for porcine cell reprogramming, but were not essential cytokines for maintaining the self-renewal and pluripotency of piPSCs. A serum-free 3i medium, which includes three inhibitors CHIR99021, SB431542, and PD0325901, three cytokines BMP4, SCF, and IL-6, and human platelet lysates (PL), was made through serious selections. In 3i condition, the doxycycline-inducible iPSCs could be passaged for a long term without the addition of doxycycline, and the flattened morphology of intermediate state piPSCs could convert to the naïve-like morphology with the increase in endogenous pluripotent gene expressions. Additionally, pPSC cell line isolated from 5.5 days blastocysts could be sustained in 3i medium and the expression of endogenous pluripotent genes OCT4, ESRRB, and STELLA was significantly increased. Our finding directed a new reprogramming strategy by using 3i condition to maintain and convert primed piPSCs into naïve-like pluripotent state. A combination of traditional LIF/b-FGF conditions and 3i condition may help us to find out an appropriate reprogramming approach to generate the naïve state of porcine iPSCs.

Abstract
ERas is a new gene recently found in mouse embryonic stem (ES) cells and localized on the X chromosome. It plays a role in mouse ES cell survival and is constitutively active without any mutations. It was also found to be responsible for the maintenance of quiescence of the hepatic stellate cells (HSCs), liver-resident mesenchymal stem cells, the activation of which results in liver fibrosis. This gene was not present in human ES cells. ERas was found to be activated in a significant population of human gastric cancer, where ERAS may play a crucial role in gastric cancer cell survival and metastases to liver via down-regulation of E-cadherin. ERas gene has been found to be expressed both in ES cells and adult tissues of cynomolgus monkey. Cynomolgus ERAS did not promote cell proliferation or induce tumor formation. ERAS was also detected in normal and neoplastic urothelium of the urinary bladder in cattle, where bovine ERAS formed a constitutive complex with platelet derived growth factor β receptor (PDGFβR) resulting in the activation of AKT signaling. Here, molecular and morphological findings of ERAS in the full term placenta of pregnant cows have been investigated for the first time. ERAS was studied by reverse transcriptase PCR (RT-PCR). Alignment of the sequence detects a 100% identity with all transcript variant bovine ERas mRNAs, present in the GenBank database (http://www.ncbi.nlm.nih.gov). Furthermore, ERAS was detected by Western blot and investigated by real time PCR that revealed an amount of ERAS more than ERAS found in normal bovine urothelium but less than ERAS present in the liver. Immunohistochemical examination revealed the presence of ERAS protein both at the level of plasma membrane and in cytoplasm of epithelial cells lining caruncular crypts and in trophoblasts of villi. An evident ERAS immunoreactivity was also seen throughout the chorionic and uterine gland epithelium. Although this is not a functional study and further investigations will be warranted, it is conceivable that ERAS may have pleiotropic effects in the placenta, some of which, like normal urothelial cells, might lead to activation of AKT pathway. We speculate that ERAS may play a key role in cellular processes such as cell differentiation and movement. Accordingly, we believe it may be an important factor involved in trophoblast invasiveness via AKT signaling pathway. Therefore, ERas gene is a functional gene which contributes to homeostasis of bovine placenta.

Abstract
Induced pluripotent stem (iPS) cell technology lead terminally differentiated cells into the pluripotent stem cells through the expression of defined reprogramming factors. Although, iPS cells have been established in a number of mammalian species, including mouse, human, and monkey, studies on iPS cells in avian species are still very limited. To establish chick iPS cells, six factors were used within the poly-cistronic reprogramming vector (PB-R6F), containing M3O (MyoD derived transactivation domain fused with Oct3/4), Sox2, Klf4, c-Myc, Lin28, and Nanog. The PB-R6F derived iPS cells were alkaline-phosphatase and SSEA-1 positive, which are markers of pluripotency. Elevated levels of endogenous Oct3/4 and Nanog genes were detected in the established iPS cells, suggesting the activation of the FGF signaling pathway is critical for the pluripotent status. Histological analysis of teratoma revealed that the established chick iPS cells have differentiation ability into three-germ-layer derived tissues. This is the first report of establishment of avian derived iPS cells with a single poly-cistronic transposon based expression system. The establishment of avian derived iPS cells could contribute to the genetic conservation and modification of avian species.

Abstract
The cellular conditions required to establish induced pluripotent stem cells (iPSCs), such as the number of reprogramming factors and/or promoter selection, differ among species. The establishment of iPSCs derived from cells of
previously unstudied species therefore requires the extensive optimization of programming conditions, including promoter selection and the optimal number of reprogramming factors, through a trial-and-error approach. While the four
Yamanaka factors Oct3/4, Sox2, Klf4, and c-Myc are sufficient for iPSC establishment in mice, we reported previously that six reprogramming factors were necessary for the creation of iPSCs from primary prairie vole-derived cells.
Further to this study, we now show detailed data describing the optimization protocol we developed in order to obtain iPSCs from immortalized prairie vole-derived fibroblasts. Immortalized cells can be very useful tools in the
optimization of cellular reprogramming conditions, as cellular senescence is known to dramatically decrease the efficiency of iPSC establishment. The immortalized prairie vole cells used in this optimization were designated K4DT
cells as they contained mutant forms of CDK4, cyclin D, and telomerase reverse transcriptase (TERT). We show that iPSCs derived from these immortalized cells exhibit the transcriptional silencing of exogenous reprogramming factors
while maintaining pluripotent cell morphology. There were no observed differences between the iPSCs derived from primary and immortalized prairie vole fibroblasts. Our data suggest that cells that are immortalized with mutant
CDK4, cyclin D, and TERT provide a useful tool for the determination of the optimal conditions for iPSC establishment.
