Abstract
Mammals are routinely cloned by introducing somatic nuclei into enucleated oocytes. Cloning contributes to propagating desired animals, to germplasm conservation efforts, among other applications. A challenge to more broader use of this technology is the relatively low cloning efficiency, which inversely correlates with donor cell differentiation status. Emerging evidence suggests that adult multipotent stem cells improve cloning efficiency, while the greater potential of embryonic stem cells for cloning remains restricted to the mouse. The derivation of pluripotent or totipotent stem cells from livestock and wild species and their association with modulators of epigenetic marks in donor cells should increase cloning efficiency.

Abstract
Somatic cell nuclear transfer (SCNT) is a method with unique ability to reprogram the epigenome of a fully differentiated cell. However, its efficiency remains extremely low. In this work, we assessed and combined two simple strategies to improve the SCNT efficiency in the bovine. These are the use of less-differentiated donor cells to facilitate nuclear reprogramming and the embryo aggregation (EA) strategy that is thought to compensate for aberrant epigenome reprogramming. We carefully assessed the optimal time of EA by using in vitro-fertilized (IVF) embryos and evaluated whether the use of adipose-derived mesenchymal stem cells (ASCs) as donor for SCNT together with EA improves the blastocyst rates and quality. Based on our results, we determined that the EA improves the preimplantation embryo development per well of IVF and SCNT embryos. We also demonstrated that day 0 (D0) is the optimal aggregation time that leads to a single blastocyst with uniform distribution of the original blastomeres. This was confirmed in bovine IVF embryos and then, the optimal condition was translated to SCNT embryos. Notably, the relative expression of the trophectoderm (TE) marker KRT18 was significantly different between aggregated and nonaggregated ASC-derived embryos. In the bovine, no effect of the donor cell is observed on the developmental rate, or the embryo quality. Therefore, no synergistic effect of the use of both strategies is observed. Our results suggest that EA at D0 is a simple and accessible strategy that improves the blastocyst rate per well in bovine SCNT and IVF embryos and influence the expression of a TE-related marker. The aggregation of two ASC-derived embryos seems to positively affect the embryo quality, which may improve the postimplantation development.

Abstract
As an important histone acetylase, the transcriptional coactivator P300/CBP affects target gene expression and plays a role in the maintenance of stem cell characteristics and differentiation potential. In this study, we explored the action of a highly effective selective histone acetylase inhibitor, C646, on goat adipose-derived stem cells (gADSCs), and investigated the impact of histone acetylation on the growth characteristics and the differentiation potential of ADSCs. We found that C646 blocked the cell proliferation, arrested the cell cycle, and triggered apoptosis. Notably, immunocytochemistry and western blot analyses showed that the acetylation level of histone H3K9 was increased. Moreover, although real-time quantitative PCR and western blot confirmed that P300 expression was inhibited under these conditions, the expression level of two other histone acetylases, TIP60 and PCAF, was significantly increased. Furthermore, C646 clearly promoted the differentiation of gADSCs into adipocytes and had an impact on their differentiation into neuronal cells. This study provides new insights into the epigenetic regulation of stem cell differentiation and may represent an experimental basis for the comprehension of stem cell characteristics and function. Furthermore, it is of great relevance for the application of adult stem cells to somatic cell cloning, which may improve the efficiency of large livestock cloning and foster the production of transgenic animals.

Abstract
The stem cells, owing to their special characteristics like self-renewal, multiplication, homing, immunomodulation, anti-inflammatory, and dedifferentiation are considered to carry an "all-in-one-solution" for diverse clinical problems. However, the limited understanding of cellular physiology currently limits their definitive therapeutic use. Among various stem cell types, currently mesenchymal stem cells are extensively studied for dog clinical applications owing to their readily available sources, easy harvesting, and ability to differentiate both into mesodermal, as well as extramesodermal tissues. The isolated, culture expanded, and characterized cells have been applied both at preclinical as well as clinical settings in dogs with variable but mostly positive results. The results, though positive, are currently inconclusive and demands further intensive research on the properties and their dependence on the applications. Further, numerous clinical conditions of dog resemble to that of human counterparts and thus, if proved rewarding in the former may act as basis of therapy for the latter. The current review throws some light on dog mesenchymal stem cell properties and their potential therapeutic applications.

Abstract
Animal cloning has gained popularity as a method to produce genetically identical animals or superior animals for research or industrial uses. However, the long-standing question of whether a cloned animal undergoes an accelerated aging process is yet to be answered. As a step towards answering this question, we compared longevity and health of Snuppy, the world’s first cloned dog, and its somatic cell donor, Tai, a male Afghan hound. Briefly, both Snuppy and Tai were generally healthy until both developed cancer to which they succumbed at the ages of 10 and 12 years, respectively. The longevity of both the donor and the cloned dog was close to the median lifespan of Afghan hounds which is reported to be 11.9 years. Here, we report creation of 4 clones using adipose-derived mesenchymal stem cells from Snuppy as donor cells. Clinical and molecular follow-up of these reclones over their lives will provide us with a unique opportunity to study the health and longevity of cloned animals compared with their cell donors.

Abstract
OBJECTIVES Recent studies have reported the existence of stem cells in ovarian tissue that show enhanced proliferative and differentiation potential compared to other adult tissues. Based on this evidence, we hypothesized that ovarian tissue contained mesenchymal-like stem cells (MSC) that could be isolated using a novel rapid plastic adhesion technique. MATERIALS AND METHODS We established MSC lines derived from ovarian and adipose tissue based on their ability to rapidly adhere to plastic culture dishes in the first 3 hours after plating and studied their potentiality in terms of molecular markers and differentiation capacity. RESULTS Morphological and kinetic properties of in vitro cultured ovarian MSC were similar to adipose-derived MSC, and both reached senescence after similar passage numbers. Ovarian-derived MSC expressed mesenchymal (CD90 and CD44) but not haematopoietic markers (CD34 and CD45), indicating similarity to adipose-derived MSC. Moreover, ovarian-derived MSC expressed NANOG, TERT, SOX2, OCT4 and showed extensive capacity to differentiate not only into adipogenic, osteogenic and chondrogenic tissue but also towards neurogenic and endodermal lineages and even precursors of primordial germ cells. CONCLUSION These results show for the first time the derivation of ovarian cells with the molecular properties of MSC as well as wide differentiation potential. Canine ovarian tissue is accessible, expandable, multipotent and has high plasticity, holding promise for applications in regenerative medicine.

Abstract
Data analysis in somatic cell nuclear transfer (SCNT) research is usually limited to several hundreds or thousands of reconstructed embryos. Here, we report mass results obtained with an established and consistent porcine SCNT system (handmade cloning [HMC]). During the experimental period, 228,230 reconstructed embryos and 82,969 blastocysts were produced. After being transferred into 656 recipients, 1070 piglets were obtained. First, the effects of different types of donor cells, including fetal fibroblasts (FFs), adult fibroblasts (AFs), adult preadipocytes (APs), and adult blood mesenchymal (BM) cells, were investigated on the further in vitro and in vivo development. Compared to adult donor cells (AFs, APs, BM cells, respectively), FF cells resulted in a lower blastocyst/reconstructed embryo rate (30.38% vs. 37.94%, 34.65%, and 34.87%, respectively), but a higher overall efficiency on the number of piglets born alive per total blastocysts transferred (1.50% vs. 0.86%, 1.03%, and 0.91%, respectively) and a lower rate of developmental abnormalities (10.87% vs. 56.57%, 24.39%, and 51.85%, respectively). Second, recloning was performed with cloned adult fibroblasts (CAFs) and cloned fetal fibroblasts (CFFs). When CAFs were used as the nuclear donor, fewer developmental abnormalities and higher overall efficiency were observed compared to AFs (56.57% vs. 28.13% and 0.86% vs. 1.59%, respectively). However, CFFs had an opposite effect on these parameters when compared with CAFs (94.12% vs. 10.87% and 0.31% vs. 1.50%, respectively). Third, effects of genetic modification on the efficiency of SCNT were investigated with transgenic fetal fibroblasts (TFFs) and gene knockout fetal fibroblasts (KOFFs). Genetic modification of FFs increased developmental abnormalities (38.96% and 25.24% vs. 10.87% for KOFFs, TFFs, and FFs, respectively). KOFFs resulted in lower overall efficiency compared to TFFs and FFs (0.68% vs. 1.62% and 1.50%, respectively). In conclusion, this is the first report of large-scale analysis of porcine cell nuclear transfer that provides important data for potential industrialization of HMC technology.

Abstract
Ectopic liver and gallbladder are rare anomalies usually not accompanied by any symptoms and are found during surgical exploration or autopsy. We aimed to find a cause of this anomaly using somatic cell nuclear transfer (SCNT) technology, which can produce genetically identical organisms. A cloned beagle having ectopic organs was produced and died on the day of birth. Major and ectopic organs were fixed and underwent histologic analysis. SCNT was performed using cells derived from the dead puppy to produce reclones. Normality of internal organs in the original donor dog and recloned dogs was evaluated by computed tomography. While a liver without the gallbladder was located in the abdominal cavity of the cloned dog, a well-defined, reddish brown mass with a small sac was also positioned outside of the thoracic cavity. Histologically, they presented as normal liver and gallbladder. Five reclones were produced, and computed tomography results revealed that the original donor dog and reclones had normal liver and gallbladder structure and location. This is the first report of both ectopic liver and gallbladder in an organism and investigation on the etiology of these abnormalities. Normal organ structure and position in the original donor dog and reclones suggests that the ectopic liver and gallbladder is a possible nonheritable anomaly.

Abstract
The limited success of somatic cell nuclear transfer (SCNT) is largely attributed to defects in epigenetic reprogramming of the donor genome. Donor cell types with distinct potential competence may offer different epigenetic flexibility for subsequent genome reprogramming in SCNT. Stem cells possibly enable their genomes to be more readily reprogrammed than differentiated cells. To improve the efficiency of cloning, porcine mesenchymal stem cells (pMSCs) were isolated and well identified by 6-channel flow cytometry and differentiation assays and were used as donors in SCNT. Compared with porcine embryonic fibroblasts (pEFs), our results showed that pMSCs markedly enhanced cloned embryo development in terms of cleavage and blastocyst formation (p < 0.05). To enhance the epigenetic flexibility of pMSCs, classical reprogramming factors (RFs) were transfected by electroporation, and we achieved optimization with ectopic expression of RFs in pMSCs. Our results suggest that the epigenetic status of donor cells has an improvement on genome reprogramming, and multipotent pMSCs favoured subsequent embryonic development.

Adenovirus-mediated expression of human sodium-iodide symporter gene permits in vivo tracking of adipose tissue-derived stem cells in a canine myocardial infarction model. Nucl Med Biol 2015; 42:621-9. [PMID: 25899941 DOI: 10.1016/j.nucmedbio.2015.03.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Revised: 02/02/2015] [Accepted: 03/16/2015] [Indexed: 11/23/2022]
Abstract
INTRODUCTION In vivo tracking of the transplanted stem cells is important in pre-clinical research of stem cell therapy for myocardial infarction. We examined the feasibility of adenovirus-mediated sodium iodide symporter (NIS) gene to cell tracking imaging of transplanted stem cells in a canine infarcted myocardium by clinical single photon emission computed tomography (SPECT). METHODS Beagle dogs were injected intramyocardially with NIS-expressing adenovirus-transfected canine stem cells (Ad-hNIS-canine ADSCs) a week after myocardial infarction (MI) development. (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) and (99m)Tc-pertechnetate ((99m)TcO4(-)) SPECT imaging were performed for assessment of infarcted myocardium and viable stem cell tracking. Transthoracic echocardiography was performed to monitor any functional cardiac changes. RESULTS Left ventricular ejection fraction (LVEF) was decreased after LAD ligation. There was no significant difference in EF between the groups with the stem cell or saline injection. (125)I uptake was higher in Ad-hNIS-canine ADSCs than in non-transfected ADSCs. Cell proliferation and differentiation were not affected by hNIS-carrying adenovirus transfection. (99m)Tc-MIBI myocardial SPECT imaging showed decreased radiotracer uptake in the infarcted apex and mid-anterolateral regions. Ad-hNIS-canine ADSCs were identified as a region of focally increased (99m)TcO4(-) uptake at the lateral wall and around the apex of the left ventricle, peaked at 2 days and was observed until day 9. CONCLUSIONS Combination of adenovirus-mediated NIS gene transfection and clinical nuclear imaging modalities enables to trace the fate of transplanted stem cells in infarcted myocardium for translational in vivo cell tracking study for prolonged duration.

Abstract
Mesenchymal stem cells, considered one of the most promising cell types for therapeutic applications due to their capacity to secrete regenerative bioactive molecules, are present in all tissues. Stem cells derived from the adipose tissue have been increasingly used for cell therapy in humans and animals, both as freshly isolated, stromal vascular fraction (SVF) cells, or as cultivated adipose-derived stem cells (ASCs). ASCs have been characterized in different animal species for proliferation, differentiation potential, immunophenotype, gene expression, and potential for tissue engineering. Whereas canine and equine ASCs are well studied, feline cells are still poorly known. Many companies around the world offer ASC therapy for dogs, cats, and horses, although in most countries these activities are not yet controlled by regulatory agencies. This is the first study to review the characterization and clinical use of SVF and ASCs in spontaneously occurring diseases in veterinary patients. Although a relatively large number of studies investigating ASC therapy in induced lesions are available in the literature, a surprisingly small number of reports describe ASC therapy for naturally affected dogs, cats, and horses. A total of seven studies were found with dogs, only two studies in cats, and four in horses. Taken as a whole, the results do not allow a conclusion on the effect of this therapy, due to the generally small number of patients included, diversity of cell populations used, and lack of adequate controls. Further controlled studies are clearly needed to establish the real potential of ASC in veterinary medicine.

Abstract
In several laboratory animals and humans, adipose tissue-derived mesenchymal stem cells (ASC) are of considerable interest because they are easy to harvest and can generate a huge proliferation of cells from a small quantity of fat. In this study, we investigated: (i) the expression patterns of reprogramming-related genes in porcine ASC; and (ii) whether ASC can be a suitable donor cell type for generating cloned pigs. For these experiments, ASC, adult skin fibroblasts (AF) and fetal fibroblasts (FF) were derived from a 4-year-old female miniature pig. The ASC expressed cell-surface markers characteristic of stem cells, and underwent in vitro differentiation when exposed to specific differentiation-inducing conditions. Expression of DNA methyltransferase (DNMT)1 in ASC was similar to that in AF, but the highest expression of the DNMT3B gene was observed in ASC. The expression of OCT4 was significantly higher in FF and ASC than in AF (P < 0.05), and SOX2 showed significantly higher expression in ASC than in the other two cell types (P < 0.05). After somatic cell nuclear transfer (SCNT), the development rate of cloned embryos derived from ASC was comparable to the development of those derived using FF. Total cell numbers of blastocysts derived using ASC and FF were significantly higher than in embryos made with AF. The results demonstrated that ASC used for SCNT have a potential comparable to those of AF and FF in terms of embryo in vitro development and blastocyst formation.

Abstract
It has been suggested that co-transferring parthenogenetic embryos could improve the pregnancy success rate with cloned embryos in mammals. As an alternative to co-transferring parthenotes, in dogs we employed recipient females that possessed in vivo-fertilised embryos as a result of mating to determine whether mated bitches could be suitable recipients for cloned embryos. The effect of using mated recipients on implantation and pregnancy rates of canine somatic cell nuclear transfer embryos was also determined. Cloned embryos were transferred into the oviducts of naturally synchronous females that had mated with male dogs before ovulation. The pregnancy rate appeared to be similar between mated recipients (50%) and non-mated recipients (28.57%; P>0.05). However, the delivery rate of cloned pups was significantly higher in mated recipients than non-mated recipients (10.53 vs 2.38%; P<0.05). A decrease in progesterone levels in the mated recipients before the due date induced natural delivery. However, cloned pups in non-mated recipients were delivered by Caesarean section because the fall in progesterone concentration in these females did not occur until the due date. The present study demonstrated for the first time that mated female dogs can be used as recipients for cloned embryos.

Abstract
Mesenchymal stromal cells (MSCs) are multipotent, plastic, adherent cells able to differentiate into osteoblasts, chondroblasts and adipocytes. MSCs can be isolated from many different body compartments of adult and fetal individuals. The most commonly studied MSCs are isolated from humans, mice and rats. However, studies are also being conducted with the use of MSCs that originate from different model organisms, such as cats, dogs, guinea pigs, ducks, chickens, buffalo, cattle, sheep, goats, horses, rabbits and pigs. MSCs derived from unconventional model organisms all present classic fibroblast-like morphology, the expression of MSC-associated cell surface markers such as CD44, CD73, CD90 and CD105 and the absence of CD34 and CD45. Moreover, these MSCs have the ability to differentiate into osteoblasts, chondroblasts and adipocytes. The MSCs isolated from unconventional model organisms are being studied for their potential to heal different tissue defects and injuries and for the development of scaffold compositions that improve the proliferation and differentiation of MSCs for tissue engineering.

Abstract
Somatic cell nuclear transfer (SCNT) is now an established procedure used in cloning of several species. SCNT in dogs involves multiple steps including the removal of the nuclear material, injection of a donor cell, fusion, activation of the reconstructed oocytes and finally transfer to a synchronized female recipient. There are therefore many factors that contribute to cloning efficiency. By performing a retrospective analysis of 2005-2012 published papers regarding dog cloning, we define the optimum procedure and summarize the specific feature for dog cloning.

Abstract
Over many decades assisted reproductive technologies, including artificial insemination, embryo transfer, in vitro production (IVP) of embryos, cloning by somatic cell nuclear transfer (SCNT), and stem cell culture, have been developed with the aim of refining breeding strategies for improved production and health in animal husbandry. More recently, biomedical applications of these technologies, in particular, SCNT and stem cell culture, have been pursued in domestic mammals in order to create models for human disease and therapy. The following review focuses on presenting important aspects of pre-implantation development in cattle, pigs, horses, and dogs. Biological aspects and impact of assisted reproductive technologies including IVP, SCNT, and culture of pluripotent stem cells are also addressed.

Abstract
Previous studies have demonstrated that skin stem cells expressing the pluripotency marker stage-specific embryonic antigen 3 (SSEA3) are easier to reprogram into induced pluripotent stem cells (iPSCs) than skin fibroblasts. Furthermore, it is widely speculated that the undifferentiated state may make stem cells more efficient donor cells for somatic cell nuclear transfer (SCNT). In this study, we isolated SSEA3(+) cells from goat skin fibroblast cells (SFCs) using fluorescence-activated cell sorting (FACS) and examined expression of pluripotency markers and in vitro development of cloned embryos following SCNT. Results showed that cell clusters from SSEA3(+) cells were consistently positive for alkaline phosphatase staining and pluripotency markers, Nanog, Oct4, Sox2, and SSEA3. The cleavage rate of cloned embryos derived from SSEA3(+) cells did not differ compared with SFCs (70.5±0.8% and 68.4±2.1%, respectively), but was significantly higher compared with SSEA3(-) cells (64.9±1.6%, p<0.05). The blastocyst rate was significantly increased in the SSEA3(+) cell group compared with the SFC and SSEA3(-) cell groups (30.3±1.2% vs. 21.2±0.9 and 19.0±1.0%, respectively, p<0.05). The quality of cloned blastocysts from SSEA3(+) cells was higher compared with SFCs and SSEA3(-) cells, based on total cell number and number of apoptotic cells per blastocyst. These findings suggest that using SSEA3(+) cells as donors for SCNT is beneficial for enhancing in vitro development and quality of cloned goat embryos.

Abstract
OBJECTIVES This study compared rate of cell proliferation, viability, cell size, expression patterns of genes related to pluripotency and epigenetic modification between canine foetal fibroblasts (cFF) and canine adipose tissue-derived mesenchymal stem cells (cAd-MSC). MATERIALS AND METHODS Proliferation pattern, cell viability as well as cell size at each passage of cFF and cAd-MSC were measured when cultures reached confluence. In addition, real-time PCR was performed to investigate expression of Dnmt1, HDAC1, OCT4, SOX2, BAX, BCL2 genes with reference to β-actin gene expression as an endogenous control in both cell lines. RESULTS cFF and cAd-MSC differed in number of generations, but not in doubling times, at all passages. Mean cell size of cAd-MSC was significantly smaller than that of cFF. Cell viability was significantly lower in cFFs and apoptotic level was significantly lower in cAd-MSC compared to passage-matched cFF. In the expression of genes related to pluripotency and epigenetic modification, level of HDAC1 in cAd-MSC was significantly higher than in cFF, but expression of Dnmt1 did not differ between the two groups. OCT4 and SOX2 were significantly more highly expressed in cAd-MSC compared to cFF. CONCLUSIONS cAd-MSC have higher stem-cell potential than cFF in terms of proliferation patterns, epigenetic modification and pluripotency, thus cAd-MSC could be more appropriate than cFF as donors of nuclei in somatic cell nuclear transfer for transgenesis.

Abstract
Recent studies have shown that amniotic membrane tissue is a rich source of stem cells in humans. In clinical applications, the amniotic membrane tissue had therapeutic effects on wound healing and corneal surface reconstruction. Here, we successfully isolated and identified multipotent stem cells (MSCs) from canine amniotic membrane tissue. We cultured the canine amniotic membrane-derived multipotent stem cells (cAM-MSCs) in low glucose DMEM medium. cAM-MSCs have a fibroblast-like shape and adhere to tissue culture plastic. We characterized the immunophenotype of cAM-MSCs by flow cytometry and measured cell proliferation by the cumulative population doubling level (CPDL). We performed differentiation studies for the detection of trilineage multipotent ability, under the appropriate culture conditions. Taken together, our results show that cAM-MSCs could be a rich source of stem cells in dogs. Furthermore, cAM-MSCs may be useful as a cell therapy application for veterinary regenerative medicine.

Abstract
Mature oocytes can be parthenogenetically activated by a variety of methods and the resulting embryos are valuable for studies of the respective roles of paternal and maternal genomes in early mammalian development. In the present study, we report the first successful development of parthenogenetic canine embryos to the post-implantation stage. Nine out of ten embryo transfer recipients became pregnant and successful in utero development of canine parthenotes was confirmed. For further evaluation of these parthenotes, their fetal development was compared with artificially inseminated controls and differentially expressed genes (DEGs) were compared using ACP RT-PCR, histological analysis and immunohistochemistry. We found formation of the limb-bud and no obvious differences in histological appearance of the canine parthenote recovered before degeneration occurred; however canine parthenotes were developmentally delayed with different cell cycle regulating-, mitochondria-related and apoptosis-related gene expression patterns compared with controls. In conclusion, our protocols were suitable for activating canine oocytes artificially and supported early fetal development. We demonstrated that the developmental abnormalities in canine parthenotes may result from defective regulation of apoptosis and aberrant gene expression patterns, and provided evidence that canine parthenotes can be a useful tool for screening and for comparative studies of imprinted genes.

Abstract
Mesenchymal stem cells (MSCs) have potential for use in regenerative therapeutics, since they are capable of multi-lineage differentiation. In this study, primary canine MSCs (cMSCs) were isolated from bone marrow aspirates and characterised using marker expression and morphology. cMSCs expressed CD44 and STRO-1, but not CD34 or CD45. Morphologically, cMSCs were similar to previously described MSCs and were capable of chondrocyte differentiation towards articular type cartilage, characterised by increased collagen type II vs. collagen type I expression and expression of Sox-9. cMSCs demonstrated no significant alterations in marker profiles and failed to differentiate into cardiomyocytes in response to a cardiac differentiation protocol or when co-cultured with canine cardiac stem cells. The study indicated that cMSCs can be derived readily from bone marrow and are capable of differentiation into articular cartilage, but appear to have limited ability to differentiate into cardiomyocytes using current protocols.

Abstract
The past decade has witnessed an explosion in research into adipose tissue stem cells (ASCs), facilitated by their ease of isolation from white adipose tissue (WAT) and fueled by their therapeutic potential. Recent developments have extended ASC multipotency to include endodermal and ectodermal cell types, as well as the generation of induced pluripotent stem cells. This expanding multipotency has been paralleled by burgeoning translational applications, ranging from tissue engineering to anti-cancer therapy, that are currently subject to clinical trials. However, this promise is tempered by potential pitfalls, such as tumorigenicity, and is further undermined by lingering uncertainties regarding the precise identity of ASCs. Confronting these issues will be essential if we are to bypass the pitfalls and develop the promises of ASCs.
