Abstract
The present study comprehensively evaluates the postnatal growth, hematology, telomere length, and semen attributes of multiple clones and re-clone derived from superior buffalo breeding bulls. To the best of our knowledge, we successfully produced multiple clones and a re-clone of an earlier cloned buffalo bull from an embryo developed from an adult bull's skin-derived cell for the first time. The cloned bulls' growth, blood hematology, plasma biochemistry, and telomere length were all shown to be normal at various stages of development. The bulls were used for semen production after being screened for testicular growth and training. Semen characteristics such as volume, concentration, and initial motility of fresh sperm as well as motility and kinetics characteristics such as straightness (STR), average lateral head displacement (ALH), and beat cross frequency (BCF) of frozen-thawed sperms of the cloned bulls were found to be similar to those of non-cloned bulls, including the donor bulls. Additionally, it was found that cloned bulls' functional sperm attributes, including acrosome intactness, mitochondrial membrane potential, and superoxide anion status, were comparable to those of non-cloned bulls. These characteristics are necessary for sperm to pass through the female reproductive system, penetrate the oocyte, and efficiently fertilize. Finally, this study adds to our understanding of the postnatal development, hematology, telomere length, and sperm characteristics of superior buffalo breeding bulls that have been cloned and re-cloned. The findings provide the groundwork for improving cloning practices, refining reproductive procedures, and optimizing the use of cloned genetic material in animal breeding and conservation.

Genetically Engineered Pigs as Efficient Salivary Gland Bioreactors for Production of Therapeutically Valuable Human Nerve Growth Factor. Cells 2022; 11:cells11152378. [PMID: 35954224 PMCID: PMC9368069 DOI: 10.3390/cells11152378] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/27/2022] [Accepted: 07/28/2022] [Indexed: 02/06/2023] Open
Abstract
Farm animal salivary glands hold great potential as efficient bioreactors for production of human therapeutic proteins. Nerve growth factor (NGF) is naturally expressed in animal salivary glands and has been approved for human clinical treatment. This study aims to employ transgenic (TG) pig salivary gland as bioreactors for efficient synthesis of human NGF (hNGF). hNGF-TG pigs were generated by cloning in combination with piggyBac transposon-mediated gene transfer. These hNGF-TG pigs specifically expressed hNGF protein in their salivary glands and secreted it at high levels into saliva. Surgical and nonsurgical approaches were developed to efficiently collect saliva from hNGF-TG pigs. hNGF protein was successfully purified from collected saliva and was verified to be biologically active. In an additional step, the double-transgenic pigs, where the endogenous porcine NGF (pNGF) gene was replaced by another copy of hNGF transgene, were created by cloning combined with CRISPR/Cas9-mediated homologous recombination. These double-transgenic pigs expressed hNGF but not pNGF, thus avoiding possible "contamination" of hNGF with pNGF protein during purification. In conclusion, TG pig salivary glands can be used as robust bioreactors for a large-scale synthesis of functional hNGF or other valuable proteins. This new animal pharming method will benefit both human health and biomedicine.

Abstract
Despite four decades of effort, robust propagation of pluripotent stem cells from livestock animals remains challenging. The requirements for self-renewal are unclear and the relationship of cultured stem cells to pluripotent cells resident in the embryo uncertain. Here, we avoided using feeder cells or serum factors to provide a defined culture microenvironment. We show that the combination of activin A, fibroblast growth factor and the Wnt inhibitor XAV939 (AFX) supports establishment and continuous expansion of pluripotent stem cell lines from porcine, ovine and bovine embryos. Germ layer differentiation was evident in teratomas and readily induced in vitro. Global transcriptome analyses highlighted commonality in transcription factor expression across the three species, while global comparison with porcine embryo stages showed proximity to bilaminar disc epiblast. Clonal genetic manipulation and gene targeting were exemplified in porcine stem cells. We further demonstrated that genetically modified AFX stem cells gave rise to cloned porcine foetuses by nuclear transfer. In summary, for major livestock mammals, pluripotent stem cells related to the formative embryonic disc are reliably established using a common and defined signalling environment. This article has an associated ‘The people behind the papers’ interview. Summary: We report the derivation of similar, stable and continuously expandable pluripotent stem cells related to embryonic disc epiblast from embryos of pig, sheep and cow.

Abstract
To develop novel medical technologies, pig disease models are invaluable especially in the final stages of translational research. Recently, we established a genetically engineered ornithine transcarbamylase-deficient (OTCD) pig strain. Here, we report its characterization and treatment responsiveness. OTCD pigs were obtained by mating an OTCD carrier female (OTC-Xc.186_190delXWT) with a wild-type male. Due to the X-linked recessive mode of inheritance, the disease phenotype emerged only in males. Medication with nitrogen-scavenging agents was based on a clinical protocol. OTCD pigs were born smaller than their wild-type and carrier littermates, showing anemia and faltering. Biochemically, high levels of urinary orotic acid and loss of OTC activity were observed. The natural life course of OTCD pigs was characterized by a decrease in arterial percentage saturation of oxygen and body temperature, as well as an increase in blood ammonia levels; the pigs died in 24.0 ± 5.0 h (mean ± SD, n = 6). The established standard medication composed with nitrogen-scavenging agents and transfusion nearly doubled the survival time to 42.4 ± 13.7 h (n = 6). Our OTCD pig model appropriately mimicked the human pathology. Along with established protocols in handling and medication, this is a first step in developing a large animal disease model that is useful for translational research into novel medical technologies, such as cell transplantation and gene therapy, as well as in relation to urea cycle disorder.

Abstract
This study was performed to improve production efficiency at the level of recipient pig and donor nuclei of transgenic cloned pigs used for xenotransplantation. To generate transgenic pigs, human endothelial protein C receptor (hEPCR) and human thrombomodulin (hTM) genes were introduced using the F2A expression vector into GalT-/-/hCD55+ porcine neonatal ear fibroblasts used as donor cells and cloned embryos were transferred to the sows and gilts. Cloned fetal kidney cells were also used as donor cells for recloning to increase production efficiency. Pregnancy and parturition rates after embryo transfer and preimplantation developmental competence were compared between cloned embryos derived from adult and fetal cells. Significantly higher parturition rates were shown in the group of sows (50.0 vs. 4.1%), natural oestrus (20.8 vs. 0%), and ovulated ovary (16.7 vs. 5.6%) compared with gilt, induced and non-ovulated, respectively (P < 0.05). When using gilts as recipients, final parturitions occurred in only the fetal cell groups and significantly higher blastocyst rates (15.1% vs. 21.3%) were seen (P < 0.05). Additionally, gene expression levels related to pluripotency were significantly higher in the fetal cell group (P < 0.05). In conclusion, sows can be recommended as recipients due to their higher efficiency in the generation of transgenic cloned pigs and cloned fetal cells also can be recommended as donor cells through correct nuclear reprogramming.

Abstract
We have previously established a concept of developing exogenic pancreas in a genetically modified pig fetus with an apancreatic trait, thereby proposing the possibility of in vivo generation of functional human organs in xenogenic large animals. In this study, we aimed to demonstrate a further proof-of-concept of the compensation for disabled organogeneses in pig, including pancreatogenesis, nephrogenesis, hepatogenesis, and vasculogenesis. These dysorganogenetic phenotypes could be efficiently induced via genome editing of the cloned pigs. Induced dysorganogenetic traits could also be compensated by allogenic blastocyst complementation, thereby proving the extended concept of organ regeneration from exogenous pluripotent cells in empty niches during various organogeneses. These results suggest that the feasibility of blastocyst complementation using genome-edited cloned embryos permits experimentation toward the in vivo organ generation in pigs from xenogenic pluripotent cells.

Establishment and identification of cell lines from type O blood Korean native pigs and their efficiency in supporting embryonic development via somatic cell nuclear transfer. J Vet Sci 2018; 19:492-499.

Abstract
Due to their similarities with humans in anatomy, physiology, and genetics miniature pigs are becoming an attractive model for biomedical research. We aim to establish and evaluate blood type O cells derived from Korean native pig (KNP), a typical miniature pig breed in Korea. Ten cell lines derived from 8 KNP piglets and one adult female KNP (kidney and ear tissues) were established. To confirm the presence of blood type O, genomic DNA, fucosyltransferase (FUT) expression, and immunofluorescence staining were examined. Additionally, fluorescence-activated cell sorting and somatic cell nuclear transfer were performed to investigate the normality of the cell lines and to evaluate their effectiveness in embryo development. We found no significant bands corresponding to specific blood group A, and no increase in FUT expression in cell lines derived from piglets No. 1, No. 4, No. 5, No. 8, and the adult female KNP; moreover, they showed normal levels of expression of α 1,3-galactosyltransferase and cytidine monophosphate-N-acetylneuraminic acid hydroxylase. There was no significant difference in embryo development between skin and kidney fibroblasts derived from the blood type O KNPs. In conclusion, we successfully established blood type O KNP cell lines, which may serve as a useful model in xenotransplantation research.

Abstract
In our previous study, we found that treatment of miniature pig somatic cell nuclear transfer (SCNT) embryos with 4 mM valproic acid (VPA), a histone deacetylase inhibitor, for 48 hours after activation enhanced blastocyst formation rate and octamer-binding transcription factor-3/4 (Oct-3/4) gene expression at the late blastocyst stage; however, the production of viable cloned pups failed, when those VPA-treated SCNT embryos were transferred to recipients. This failure suggests that the present VPA treatment is suboptimal. In the present study, we explored the optimal conditions for VPA to have beneficial effects on the development of SCNT embryos. When miniature pig SCNT embryos were treated with 8 mM VPA for 24 hours after activation, both the rates of blastocyst formation and blastocysts expressing the Oct-3/4 gene were significantly (p < 0.05) improved. A similar increase in blastocyst formation was also observed when microminipig-derived cells were used as SCNT donors. Five cloned piglets were obtained after the transfer of 152 microminipig SCNT embryos that had been treated with 8 mM VPA for 24 hours. The results indicated that a short duration of treatment with VPA improves the development of both miniature pig and microminipig SCNT embryos, possibly via an enhanced reprogramming mechanism.

Abstract
The nucleosome, the fundamental structural unit of chromatin, is a critical regulator of gene expression. The mechanisms governing changes to nucleosome occupancy and positioning during somatic cell reprogramming remain poorly understood. We established a method for generating genome-wide nucleosome maps of porcine embryonic fibroblasts (PEF), reconstructed 1-cell embryos generated by somatic cell nuclear transfer (SCNT), and fertilized zygotes (FZ) using MNase sequencing with only 1,000 cells. We found that donor PEF chromatin, especially X chromosome, became more open after transfer into porcine oocytes and nucleosome occupancy decreased in promoters but increased in the genic regions. Nucleosome arrangements around transcriptional start sites of genes with different expression levels in somatic cells tended to become transcriptionally silent in SCNT; however, some pluripotency genes adopted transcriptionally active nucleosome arrangements. FZ and SCNT had similar characteristics, unlike PEF. This study reveals the dynamics and importance of nucleosome positioning and chromatin organization early after reprogramming.

Abstract
Objective The present study investigates pre- and post-implantation developmental competence of nuclear-transferred porcine embryos derived from male and female fetal fibroblasts. Methods Male and female fetal fibroblasts were transferred to in vitro-matured enucleated oocytes and in vitro and in vivo developmental competence of reconstructed embryos was investigated. And, a total of 6,789 female fibroblast nuclear-transferred embryos were surgically transferred into 41 surrogate gilts and 4,746 male fibroblast nuclear-transferred embryos were surgically transferred into 25 surrogate gilts. Results The competence to develop into blastocysts was not significantly different between the sexes. The mean cell number of female and male cloned blastocysts obtained by in vivo culture (143.8±10.5 to 159.2±14.8) was higher than that of in vitro culture of somatic cell nuclear transfer (SCNT) groups (31.4±8.3 to 33.4±11.1). After embryo transfer, 5 pregnant gilts from each treatment delivered 15 female and 22 male piglets. The average birth weight of the cloned piglets, gestation length, and the postnatal survival rates were not significantly different (p<0.05) between sexes. Conclusion The present study found that the sex difference of the nuclear donor does not affect the developmental rate of porcine SCNT embryos. Furthermore, postnatal survivability of the cloned piglets was not affected by the sex of the donor cell.

Abstract
Since domestication, pigs have been used extensively in agriculture and kept as companion animals. More recently they have been used in biomedical research, given they share many physiological and anatomical similarities with humans. Recent technological advances in assisted reproduction, somatic cell cloning, stem cell culture, genome editing, and transgenesis now enable the creation of unique porcine models of human diseases. Here, we highlight the potential applications and advantages of using pigs, particularly minipigs, as indispensable large animal models in fundamental and clinical research, including the development of therapeutics for inherited and chronic disorders, and cancers.

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
The effects of cytoplasmic volumes on development and developmental kinetics of in vitro produced porcine embryos were investigated. During hand-made cloning (HMC), selected cytoplasts were separated into two groups according to their size in relation to the initial oocyte: ~75% or ~50%. Following two fusion steps and activation (day 0), reconstructed embryos were cultured in vitro for 6 days. Cleavage rates on day 2 as well as blastocyst rates and cell numbers on day 6 were recorded. Results showed that embryo development was no different for ~50% versus ~75% cytoplasm at first fusion. This result was used in the following experiments, where the effect of varying cytoplasm volume in second fusion to obtain a final cytoplasm volume of ~75% to ~200% was tested. The results showed that the lowest quality was obtained when the final cytoplasm volume was ~75% and the highest quality at ~200% of the original oocyte. Similar results were observed in parthenogenetic (PA) embryos activated with different cytoplasmic volumes. A common pattern for the developmental kinetics of HMC and PA embryos was observed: the smaller group tended to have a longer time for the first two cell cycles, but subsequently a shorter time to form morula and blastocyst. In conclusion, the developmental kinetics of in vitro produced embryos was affected by the cytoplasm volume of the initial oocyte, and this further accounted for the developmental ability of the reconstructed embryos.

Abstract
Understanding the performances of cloned pigs and their offspring is critical to evaluate the practical applications of somatic cell nuclear transfer. In this study, genetic polymorphism, growth performance, hematological parameters, and reproduction characteristics of cloned Landrace boars were compared with those of controls. In addition, the growth performance of clone offspring was also evaluated. A total of 479 reconstructed embryos were transferred to five recipient pigs and resulted in the delivery of 14 piglets (overall cloning of 2.9%) from two litters. Analyses of microsatellite markers and polymorphisms of the specific genes confirmed that the 14 clones were genetically identical to the nuclear donor and maintained the desirable genotypes. Growth performance of five healthy, phenotypically normal cloned boars from one litter and eight of their male offspring did not differ from age, breed, and management-matched controls. Although some significant differences were observed between cloned and control boars in hematological and serum enzymes, most of these parameters were within the normal range. Cloned boars had less (P < 0.05) normal sperm in the ejaculated boars than in control boars (71.4% vs. 77.9%, respectively), but sperm production (ejaculate volume, sperm concentration, and total sperm) did not differ between these groups. In addition, use of frozen-thawed semen from cloned boars for insemination produced results that seemed comparable to a control. In conclusion, the present study reported that somatic cell nuclear transfer is effective in reproducing preferred genetic traits and has potential applications to conserve elite bloodlines in a routine pig breeding program.

Abstract
BACKGROUND Nuclear transfer (NT) technologies offer a means for producing the genetically modified pigs necessary to develop swine models for mechanistic studies of disease processes as well as to serve as organ donors for xenotransplantation. Most previous studies have used commercial pigs as surrogates. METHOD AND RESULTS In this study, we established a cloning technique for miniature pigs by somatic cell nuclear transfer (SCNT) using Nippon Institute for Biological Science (NIBS) miniature pigs as surrogates. Moreover, utilizing this technique, we have successfully produced an α-1, 3-galactosyltransferase knockout (GalT-KO) miniature swine. Fibroblasts procured from a NIBS miniature pig fetus were injected into 1312 enucleated oocytes. The cloned embryos were transferred to 11 surrogates of which five successfully delivered 13 cloned offspring; the production efficiency was 1.0% (13/1312). In a second experiment, lung fibroblasts obtained from neonatal GalT-KO MGH miniature swine were used as donor cells and 1953 cloned embryos were transferred to 12 surrogates. Six cloned offspring were born from five surrogates, a production efficiency of 0.3% (6/1953). CONCLUSIONS These results demonstrate successful establishment of a miniature pig cloning technique by SCNT using NIBS miniature pigs as surrogates. To our knowledge, this is the first demonstration of successful production of GalT-KO miniature swine using miniature swine surrogates. This technique could help to ensure a stable supply of the cloned pigs through the use of miniature pig surrogates and could expand production in countries with limited space or in facilities with special regulations such as specific pathogen-free or good laboratory practice.

Abstract
Somatic cell nuclear transfer (SCNT) is an important method of breeding quality varieties, expanding groups, and preserving endangered species. However, the viability of SCNT embryos is poor, and the cloned rate of animal production is low in pig. This study aims to investigate the gene function and establish a disease model of Banna miniature inbred pig. SCNT with donor cells derived from fetal, newborn, and adult fibroblasts was performed, and the cloning efficiencies among the donor cells were compared. The results showed that the cleavage and blastocyst formation rates did not significantly differ between the reconstructed embryos derived from the fetal (74.3% and 27.4%) and newborn (76.4% and 21.8%) fibroblasts of the Banna miniature inbred pig (P>0.05). However, both fetal and newborn fibroblast groups showed significantly higher rates than the adult fibroblast group (61.9% and 13.0%; P<0.05). The pregnancy rates of the recipients in the fetal and newborn fibroblast groups (60% and 80%, respectively) were higher than those in the adult fibroblast group. Eight, three, and one cloned piglet were obtained from reconstructed embryos of the fetal, newborn, and adult fibroblasts, respectively. Microsatellite analyses results indicated that the genotypes of all cloning piglets were identical to their donor cells and that the genetic homozygosity of the Banna miniature inbred pig was higher than those of the recipients. Therefore, the offspring was successfully cloned using the fetal, newborn, and adult fibroblasts of Banna miniature inbred pig as donor cells.

Abstract
SummaryIn this study, the developmental ability of cloned embryos using gilt versus sow oocytes was evaluated under the hypothesis that the efficiency of nuclear transfer using gilt oocytes was lower than that of sow oocytes, but that it could be optimized. Five experiments were performed with routine production of cloned embryos with sow oocytes serving as the control. Results showed that: Experiment 1: Blastocyst rates of cloned embryos with gilt oocytes was about half compared with control. Experiment 2: An extended maturation time of 48 h used for gilt oocytes resulted in lower blastocyst rates after cloning. Experiment 3: Development of cloned embryos with gilt oocytes was improved by co-culture with sow oocytes. Experiment 4: After maturation of gilt oocytes using follicular fluid from gilt instead of sow, the oocytes were sorted into large and small oocytes, and after cloning, blastocyst rates were higher using large gilt oocytes compared with small oocytes; however, the rate remained lower compared with control. Experiment 5: Six sow recipients received a total of 503 morulae and blastocysts cloned from gilt oocytes (four recipients) and 190 cloned from sow oocytes (two recipients). All recipients became pregnant and went to term, resulting in 26 (gilt oocytes) and six (sow oocytes) piglets. In conclusion, results confirmed that nuclear transfer efficiency was higher using sow versus gilt oocytes, but the use of gilt oocytes can be optimized by sorting after ooplasm size following maturation and by maturing gilt and sow oocytes together.

Abstract
Currently, cloning efficiency in pigs is very low. Donor cell type and number of cloned embryos transferred to an individual surrogate are two major factors that affect the successful rate of somatic cell nuclear transfer (SCNT) in pigs. This study aimed to compare the influence of different donor fibroblast cell types and different transferred embryo numbers on recipients' pregnancy rate and delivery rate, the average number of total clones born, clones born alive and clones born healthy per litter, and the birth rate of healthy clones (=total number of healthy cloned piglets born /total number of transferred cloned embryos). Three types of donor fibroblasts were tested in large-scale production of cloned pigs, including fetal fibroblasts (FFBs) from four genetically similar Western swine breeds of Pietrain (P), Duroc (D), Landrace (L), and Yorkshire (Y), which are referred to as P,D,LY-FFBs, adult fibroblasts (AFBs) from the same four breeds, which are designated P,D,L,Y-AFBs, and AFBs from a Chinese pig breed of Laiwu (LW), which is referred to as LW-AFBs. Within each donor fibroblast cell type group, five transferred cloned embryo number groups were tested. In each embryo number group, 150-199, 200-249, 250-299, 300-349, or 350-450 cloned embryos were transferred to each individual recipient sow. For the entire experiment, 92,005 cloned embryos were generated from nearly 115,000 matured oocytes and transferred to 328 recipients; in total, 488 cloned piglets were produced. The results showed that the mean clones born healthy per litter resulted from transfer of embryos cloned from LW-AFBs (2.53 ± 0.34) was similar with that associated with P,D,L,Y-FFBs (2.72 ± 0.29), but was significantly higher than that resulted from P,D,L,Y-AFBs (1.47 ± 0.18). Use of LW-AFBs as donor cells for SCNT resulted in a significantly higher pregnancy rate (72.00% vs. 59.30% and 48.11%) and delivery rate (60.00% vs. 45.93% and 35.85%) for cloned embryo recipients, and a significantly higher birth rate of healthy clones (0.5009% vs. 0.3362% and 0.2433%) than that resulting from P,D,L,Y-AFBs and P,D,L,Y-FFBs. This suggests that using LW-AFBs as donor cells results in a higher cloning efficiency in pigs, compared with the other two donor fibroblast cell types. The birth rate of healthy clones was significantly improved when the number of transferred cloned embryos was increased from 150-199 to 200-450 per recipient. However, increase of the number of transferred embryos from 200-249 to 250-450 per surrogate did not change the birth rate of healthy clones. This suggests that transfer of excessive (250-450) cloned embryos to an individual surrogate is not necessary for increasing the cloning efficiency in pigs, and the relatively optimal number of reconstructed embryos transferred to individual recipient is 200-249. Furthermore, our results indicated that the numbers of total born clones, clones born alive, and clones born healthy per litter have a significantly high positive correlation with each other. The present study provides useful information for improving SCNT efficiency in pigs.

Abstract
Production of transgenic animals via somatic cell nuclear transfer (SCNT) has been adapted worldwide, but this application is somewhat limited by its relatively low efficiency. In this study, we used handmade cloning (HMC) established previously to produce transgenic pigs that express the functional nematode fat-1 gene. Codon-optimized mfat-1 was inserted into eukaryotic expression vectors, which were transferred into primary swine donor cells. Reverse transcriptase PCR (RT-PCR), gas chromatography, and chromosome analyses were performed to select donor clones capable of converting n-6 into n-3 fatty acids. Blastocysts derived from the clones that lowered the n-6/n-3 ratio to approximately 1:1 were transferred surgically into the uteri of recipients for transgenic piglets. By HMC, 37% (n=558) of reconstructed embryos developed to the blastocyst stage after 7 days of culture in vitro, with an average cell number of 81±36 (n=14). Three recipients became pregnant after 408 day-6 blastocysts were transferred into four naturally cycling females, and a total of 14 live offspring were produced. The nematode mfat-1 effectively lowered the n-6/n-3 ratio in muscle and major organs of the transgenic pig. Our results will help to establish a reliable procedure and an efficient option in the production of transgenic animals.

Abstract
In this study, we examined whether Hanganutziu-Deicher (H-D) antigens are important as an immunogenic non-α1,3-galactose (Gal) epitope in pigs with a disrupted α1,3-galactosyltransferase gene. The targeting efficiency of the AO blood genotype was achieved (2.2%) in pig fibroblast cells. A total of 1800 somatic cell nuclear transfer (SCNT) embryos were transferred to 10 recipients. One recipient developed to term and naturally delivered two piglets. The α1,3-galactosyltransferase activity in lung, liver, spleen, and testis of heterozygote α1,3-galactosyltransferase gene knockout (GalT-KO) pigs was significantly decreased, whereas brain and heart showed very low decreasing levels of α1,3-galactosyltransferase activity when compared to those of control. Enzyme-linked lectinosorbent assay showed that the heterozygote GalT-KO pig had more sialylα2,6- and sialylα2,3-linked glycan than the control. Furthermore, the heart, liver, and kidney of the heterozygote GalT-KO pig had a higher N-glycolylneuraminic acid (Neu5Gc) content than the control, whereas the lung of the heterozygote GalT-KO pig had Neu5Gc content similar to the control. Collectively, the data strongly indicated that Neu5Gc is a more critical xenoantigen to overcoming the next acute immune rejection in pig to human xenotransplantation.

Abstract
Transgenic animals are an important source of protein and nutrition for most humans and will play key roles in satisfying the increasing demand for food in an ever-increasing world population. The past decade has experienced a revolution in the development of methods that permit the introduction of specific alterations to complex genomes. This precision will enhance genome-based improvement of farm animals for food production. Precision genetics also will enhance the development of therapeutic biomaterials and models of human disease as resources for the development of advanced patient therapies.

Abstract
The perinatal mortality of cloned animals is a well-known problem. In the present retrospective study, we report on mortality of cloned transgenic or non-transgenic piglets produced as part of several investigations. Large White (LW) sows (n = 105) received hand-made cloned LW or minipig blastocysts and delivered either spontaneously or after prostaglandin induction followed by either Caesarean section or vaginal birth. The overall pregnancy rate was 62%, with 26% of pregnancies terminating before term. This resulted in 48 deliveries. The terminated pregnancies consisted of 12 abortions that occurred at 35 ± 2 days gestation and five sows that went to term without returning to heat and then by surgery showed the uterus without fetal content. The gestation length was for sows with LW piglets that delivered by Caesarean section or vaginally was 115.7 ± 0.3 and 117.6 ± 0.4 days, respectively. In sows with minipiglets, the gestation length for those delivered by Caesarean section or vaginally 114.4 ± 0.2 and 115.5 ± 0.3 days, respectively. Of the 34 sows that delivered vaginally, 28 gave birth after induction, whereas 6 farrowed spontaneously. Of the 14 sows that delivered after Caesarean section and in the five empty sows, the endometrium and placenta showed severe oedema. Piglet mortality following vaginal delivery was higher than after Caesarean section (31% v. 10%, respectively; P < 0.001). When vaginal delivery occurred spontaneously, the stillborn rate was greater than after induced delivery (56% v. 24%, respectively; P < 0.0001). Internal organ weights were recorded for seven cloned LW piglets and six normal piglets. The relative weight of the heart, liver, kidneys and small intestine was found to be reduced in the cloned piglets (P < 0.05). The present study demonstrates extensive endometrial oedema in sows pregnant with cloned and transgenic piglets, as well as in empty recipients, at term. The growth of certain organs in some of the cloned piglets was reduced and the rate of stillborn piglets was greater in cloned and transgenic piglets delivered vaginally, possibly because of oedema of the fetal-maternal interface.

Abstract
This study was carried out to examine the effect of postactivation treatment with latrunculin A (LatA), an actin polymerisation inhibitor, on in vitro and in vivo development of somatic cell nuclear transfer (SCNT) embryos derived from gene-modified Clawn miniature pig cells. After the fusion and activation, SCNT embryos were treated with or without a cytoskeletal inhibitor [LatA or 10.4 microM cytochalasin B (CB) for 2 h]. The cleavage rate was significantly higher (p < 0.05) in embryos exposed to 0.5 microM LatA than those in embryos exposed to CB and without a cytoskeletal inhibitor. Moreover, the blastocyst formation rate was significantly higher (p < 0.05) in embryos exposed to 0.5 or 1 microM LatA than those in embryos exposed to CB and without a cytoskeletal inhibitor. In addition, five fetuses were obtained from recipient uteri after transfer of embryos treated with 0.5 muM LatA. The results of this study show for the first time that postactivation treatment with LatA is effective to improve in vitro developmental capacity of gene-modified cloned miniature pig embryos and embryos treated with LatA have the ability to develop into fetuses.

Abstract
The aim of the present study was to examine the effect of various intervals between electrofusion and activation (FA interval) on the nuclear remodelling and development of somatic cell nuclear transfer (SCNT) embryos in pigs. Reconstructed oocytes were activated at 0 (simultaneous fusion and activation; SFA), 1, 2 and 3 h (delayed activation) after electrofusion; these groups were designated as DA1, DA2 and DA3, respectively. When oocyte nuclear status was examined at 0.5, 1, 2 and 3 h after electrofusion, the incidence of chromosome scattering was increased (P < 0.01) as the FA interval was extended (0.0%, 12.0%, 77.3% and 78.0%, respectively). Extending the FA interval led to an increase (P < 0.01) in the percentage of oocytes containing multiple (>or=3) pseudopronuclei (PPN) (0.0% of SFA; 5.3% of DA1; 21.7% of DA2; and 33.5% of DA3). The development of SCNT embryos to the blastocyst stage was decreased (P < 0.05) in DA2 (5.7%) and DA3 (5.0%) compared with SFA (18.1%) and DA1 (19.5%). Our results demonstrate that extending the FA interval impairs the development of SCNT pig embryos by inducing chromosome scattering and the formation of multiple PPN, which may result in increased nuclear aneuploidy.

Pregnancies and piglets from large white sow recipients after two transfer methods of cloned and transgenic embryos of different pig breeds. Theriogenology 2010; 74:1233-40. [PMID: 20688371 DOI: 10.1016/j.theriogenology.2010.05.026] [Citation(s) in RCA: 56] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2010] [Revised: 05/21/2010] [Accepted: 05/21/2010] [Indexed: 11/16/2022]
Abstract
The aim of this study was to report from a larger study with pregnancy and delivery results after transfer of cloned transgenic/non-transgenic Large White or minipig embryos to Large White sow recipients. The effect of both total numbers of transferred embryos as well as site of their deposition (uni- vs. bi-lateral) was studied. Four to five days after natural heat, 85 Large White (LW) sows received Day 5 or 6 handmade cloned embryos. Large White embryos were non-transgenic and were transferred to 36 recipients, while 49 recipients each received Minipig embryos, either non-transgenic or with 1 of 4 types of transgenes. Furthermore, the number of embryos transferred was in two categories, as 46 recipients received 40-60 embryos while 39 received 60-120 embryos. Finally, in 59 of the recipients embryos were transferred to one of the uterine horns (unicornual) while 26 other recipients had embryos transferred to both uterine horns (bicornual). The overall pregnancy rate was 55% with an abortion rate of 26% resulting in 41% deliveries with no difference between LW and Minipig embryos and no difference between transgenic and non-transgenic Minipig embryos. Transfer of 60-120 embryos resulted in more pregnancies and deliveries (62%) than <60 embryos (24%). The mean litter size was 5.1 ± 0.5 and after transfer of 60-120 embryos significantly higher (6.0 ± 0.5) than after transfer of <60 embryos (3.5 ± 0.8). Also, the bicornual transfer resulted in significantly higher delivery rate (74% vs. 44%) and mean litter size (6.1 ± 0.7 vs. 4.2 ± 0.6) than the unicornual. The mean rate of piglets/transferred embryos was 7.3 ± 0.6% while the mean rate of piglets/reconstructed embryos was 179/18,000 = 1% with no difference between breeds or number of embryos transferred. The overall perinatal mortality rate was 49%, and it was significantly lower in LW piglets (20/59 = 34%) than in Minipiglets (67/120 = 56%) (vs. 10-15% in normal piglets at the farm) and the total rate of piglets with one or more malformation was 22%, and lower in LW (12%) than in Minipiglets (28%). This study demonstrate that although the perinatal mortality was rather high, an acceptable birth rate can be achieved after transfer to LW recipients of cloned LW embryos as well as cloned, transgenic/non-transgenic Minipig embryos. Furthermore, the pregnancy rate and litter size were correlated to the number of embryos transferred and to bicornual transfer.

Abstract
The present study compared the developmental ability of miniature pig embryos cloned with fetal fibroblasts (FFs), bone marrow-derived mesenchymal stem cells (MSCs) and differentiated (osteocytes, adipocytes and chondrocytes) MSCs. MSCs were isolated from an approximately 1-month-old female miniature pig (T-type, PWG Micro-pig((R)), PWG Genetics Korea). MSCs were differentiated into osteocytes, adipocytes and chondrocytes under controlled conditions and characterized by cell surface antigen profile using specific markers. These differentiated or undifferentiated MSCs, as well as FFs of miniature pig, were transferred into enucleated oocytes of domestic pigs. Data from 10 replicates involving 1567 cloned embryos were assessed in terms of developmental rates. The in vitro development rate to the blastocyst stage of embryos cloned with undifferentiated MSCs was significantly (P<0.05) higher than that of embryos cloned with differentiated MSCs and FFs. Surgical transfer of 523 two-cell stage embryos cloned with undifferentiated MSCs into five synchronized domestic pig recipients resulted in 5 cloned miniature pig offspring (1 stillborn and 4 viable) from 2 pregnant recipients. The results imply that MSCs might be multipotent and that they can be used to produce viable cloned miniature pigs that cannot be easily reproduced with differentiated somatic cells.

Abstract
Expression of recombinant human lysosomal acid beta-glucosidase (hGCase) by a transgenic animal bioreactor, using somatic cell nuclear transfer (SCNT), would decrease the cost of producing this product. The objective was to establish an effective procedure to prepare hGCase transgenic donor cells and nuclear transfer (NT) embryos to produce hGCase protein in the Saanen dairy goat mammary gland. A mammary-specific expression vector for hGCase was constructed and transfected into HC-11 mammary epithelial cells for bioactivity analysis in vitro; mRNA transcripts and hGCase protein were correctly expressed in transfected HC-11 cells. The hGCase gene was then introduced into fetal fibroblasts (from dairy goats) to prepare competent transgenic donor cells. Transgenic fibroblast clones from a single round of transfection were reliably isolated by 96-well cell culture plates and screened with PCR amplification and chromosomal counting (66.8%). Dairy goat cloned embryos were produced from these hGCase fetal cells by SCNT, the hGCase transgene was successfully detected in these embryos, and there were similar rates (P>0.05) of fusion (83.3% vs. 77.8%), cleavage (89.1% vs. 90.9%), and development to the morula/blastocyst stages (36.4% vs. 38.9%) between NT embryos using transgenic fetal fibroblasts and non-transfected control cells. Moreover, 98 well-developed reconstructed embryos derived from transgenic cells were transferred to 16 recipients; pregnancy was confirmed at 40 d in two goats. Therefore, we achieved functional expression of hGCase in mammary gland cells and normal development to Day 40 of cloned embryos carrying the hGCase gene.

Abstract
Pigs are increasingly being recognized as good large-animal models for translational research, linking basic science to clinical applications in order to establish novel therapeutics. This article reviews the current status and future prospects of genetically modified and cloned pigs in translational studies. It also highlights pigs specially designed as disease models, for xenotransplantation or to carry cell marker genes. Finally, use of porcine somatic stem and progenitor cells in preclinical studies of cell transplantation therapy is also discussed.

Abstract
PURPOSE OF REVIEW Recent developments in the field of genetic engineering have made it possible to add, delete or exchange genes from one species to another. This technology has special relevance to the field of xenotransplantation, in which the elimination of a species-specific disparity could make the difference between success and failure of an organ transplant. This review focuses on developments in both the techniques and applications of genetically modified animals. RECENT FINDINGS Advances have been made using existing techniques for genetic modifications of swine and in the development of new, emerging technologies, including enzymatic engineering and the use of small interfering RNA. Applications of the modified animals have provided evidence that genetically modified swine have the potential to overcome both physiologic and immunologic barriers that have previously impeded this field. The use of alpha-1,3-galactosyltransferase gene-knockout animals as donors have shown marked improvements in xenograft survivals. SUMMARY Techniques for genetic engineering of swine have been directed toward avoiding naturally existing cellular and antibody responses to species-specific antigens. Organs from genetically engineered animals have enjoyed markedly improved survivals in nonhuman primates, especially in protocols directed toward the induction of tolerance, presumably by avoiding immunization to new antigens.

Abstract
The miniature pig is regarded as a better organ donor breed for xenotransplantation than other pig breeds because the size of their organs is similar to that of humans. To improve efficiency of cloned miniature pig production, we analysed the effect of breed difference between donor cells and embryo recipients on pregnancy rate and delivery rate. Cloned porcine embryos derived from domestic or miniature pig donor cells were transferred to domestic or miniature recipient pigs. Delivery rate was significantly higher when embryos reconstructed with miniature pig donor cells were transferred to miniature pig recipients as compared with that of embryos transferred to domestic pig recipients. However, pregnancy rates were similar between the two groups. The breed of donor cells, but not of embryo recipients, seems likely to affect litter size. From a 13 610 gene cDNA microarray, 1551 (11.7%) genes showed significantly different levels of expression between the fetuses of the two breeds. Vascular endothelial growth factor and c-kit ligand genes related to implantation and maintenance of pregnancy were significantly down-regulated in miniature pigs. In conclusion, the differential gene expression in fetuses interferes with proper fetal/maternal interactions, and results in late-stage pregnancy loss. Our results indicate that the miniature pig is the preferred embryo recipient breed than domestic pig for producing cloned miniature piglets.

Abstract
The National Institutes of Health (NIH) miniature pig was developed specifically for xenotransplantation and has been extensively used as a large-animal model in many other biomedical experiments. However, the cloning efficiency of this pig is very low (<0.2%), and this has been an obstacle to the promising application of these inbred swine genetics for biomedical research. It has been demonstrated that increased histone acetylation in somatic cell nuclear transfer (SCNT) embryos, by applying a histone deacetylase (HDAC) inhibitor such as trichostatin A (TSA), significantly enhances the developmental competence in several species. However, some researchers also reported that TSA treatment had various detrimental effects on the in vitro and in vivo development of the SCNT embryos. Herein, we report that treatment with 500 nM 6-(1,3-dioxo-1H, 3H-benzo[de]isoquinolin-2-yl)-hexanoic acid hydroxyamide (termed scriptaid), a novel HDAC inhibitor, significantly enhanced the development of SCNT embryos to the blastocyst stage when NIH inbred fetal fibroblast cells (FFCs) were used as donors compared with the untreated group (21% vs. 9%, P < 0.05). Scriptaid treatment resulted in eight pregnancies from 10 embryo transfers (ETs) and 14 healthy NIH miniature pigs from eight litters, while no viable piglets (only three mummies) were obtained from nine ETs in the untreated group. Thus, scriptaid dramatically increased the cloning efficiency when using inbred genetics from 0.0% to 1.3%. In contrast, scriptaid treatment decreased the blastocyst rate in in vitro fertilization embryos (from 37% to 26%, P < 0.05). In conclusion, the extremely low cloning efficiency in the NIH miniature pig may be caused by its inbred genetic background and can be improved by alteration of genomic histone acetylation patterns.

Abstract
Exposure of porcine oocytes to increased concentrations of NaCl prior to manipulation has been reported not only to increase cryotolerance after vitrification, but also to improve developmental competence after somatic cell nuclear transfer (SCNT). In the present study we compared the effects of NaCl with those of concentrated solutions of two non-permeable osmotic agents, namely sucrose and trehalose, on the cryotolerance and developmental competence of porcine oocytes. In Experiment 1, porcine in vitro-matured cumulus–oocyte complexes (COCs; n = 1200) were exposed to 588 mOsmol NaCl, sucrose or trehalose solutions for 1 h, allowed to recover for a further 1 h, vitrified, warmed and subjected to parthenogenetic activation. Both Day 2 (where Day 0 is the day of activation) cleavage and Day 7 blastocyst rates were significantly increased after NaCl, sucrose and trehalose osmotic treatments compared with untreated controls (cleavage: 46 ± 5%, 44 ± 7%, 45 ± 4% and 26 ± 6%, respectively; expanded blastocyst rate: 6 ± 1%, 6 ± 2%, 7 ± 2% and 1 ± 1%, respectively). In Experiment 2, COCs (n = 2000) were treated with 588 mOsmol NaCl, sucrose or trehalose, then used as recipients for SCNT (Day 0). Cleavage rates on Day 1 did not differ between the NaCl-, sucrose-, trehalose-treated and the untreated control groups (92 ± 3%, 95 ± 3%, 92 ± 2% and 94 ± 2%, respectively), but blastocyst rates on Day 6 were higher in all treated groups compared with control (64 ± 2%, 69 ± 5%, 65 ± 3% and 47 ± 4%, respectively). Cell numbers of Day 6 blastocysts were higher in the control and NaCl-treated groups compared with the sucrose- and trehalose-treated groups. In conclusion, treatment of porcine oocytes with osmotic stress improved developmental competence after vitrification combined with parthenogenetic activation, as well as after SCNT.

Abstract
Four methods of cell cycle synchronization of porcine preadipocytes for use as nuclear donors in somatic cell cloning were compared: serum starvation, differentiation induction, contact inhibition and roscovitine treatment. After three days of differentiation induction, the percentage of nuclear donor cells synchronized at the G0/G1 phase reached a peak value of 91.8%, which was significantly higher (P<0.05) than the percentage attained by serum starvation (84.9-89.8%), contact inhibition (78.3-83.7%) or roscovitine treatment (67.8-80.3%). Cell cycle synchronization by serum starvation, contact inhibition and roscovitine treatment all increased the percentage of apoptotic cells, while no increase was observed when the donor-cell cycle was synchronized by differentiation induction (Annexin V-positive: 15.7% to 19.3% vs. 7.7%, P<0.05; TUNEL-positive: 12.8% to 14.0% vs. 8.3%, P<0.05). Additionally, comparison of the in vitro development of nuclear transfer (NT) embryos formed from the nuclei of differentiation-induced or serum-starved preadipocytes revealed that, in both cases, a high proportion of embryos developed to the blastocyst stage (39.0 and 33.7%, respectively). In this study, NT embryos reconstructed with preadipocytes synchronized by differentiation induction were transferred to four recipient pigs, three of which gave birth to a total of 17 piglets (4.2%, 17/403). These results demonstrate that donor-cell cycle synchronization by differentiation induction enables effective production of cloned pigs. The findings also indicate that differentiation induction of multipotent cells is an excellent method of cell cycle synchronization that permits highly efficient synchronization of cells at the G0/G1 phase.

Abstract
The aim of the present study was to examine the production efficiency of cloned pigs by serial somatic cell nuclear transfer (SCNT) and to ascertain any changes in the telomere lengths of multiple generations of pigs. Using fetal fibroblasts as the starting nuclear donor cells, porcine salivary gland progenitor cells were collected from the resultant first-generation cloned pigs to successively produce second- and third-generation clones, with no significant differences in production efficiency, which ranged from 1.4% (2/140) to 3.3% (13/391) among the 3 generations. The average telomere lengths (terminal restriction fragment values) for the first, second and third generation clones were 16.3, 18.1 and 20.5 kb, respectively, and were comparable to those in age-matched controls. These findings suggest that third-generation cloned pigs can be produced by serial somatic cell cloning without compromising production efficiency and that the telomere lengths of cloned pigs from the first to third generations are normal.
