Abstract
Spermatogonial stem cells (SSC) are promising resources for genetic preservation and restoration of male germ cells in humans and animals. However, no studies have used SSC as donor nuclei in pig somatic cell nuclear transfer (SCNT). This study investigated the potential for use of porcine SSC as a nuclei donor for SCNT and developmental competence of SSC-derived cloned embryos. In addition, demecolcine was investigated to determine whether it could prevent rupture of SSC during SCNT. When the potential of SSC to support embryonic development after SCNT was compared with that of foetal fibroblasts (FF), SSC-derived SCNT embryos showed a higher (p < .05) developmental competence to the blastocyst stage (47.8%) than FF-derived embryos (25.6%). However, when SSC were used as donor nuclei in the SCNT process, cell fusion rates were lower (p < .05) than when FF were used (61.9% vs. 75.8%). Treatment of SSC with demecolcine significantly (p < .05) decreased rupture of SSC during the SCNT procedure (7.5% vs. 18.8%) and increased fusion of cell-oocyte couplets compared with no treatment (74.6% vs. 61.6%). In addition, SSC-derived SCNT embryos showed higher blastocyst formation (48.4%) than FF-derived embryos without (28.4%) and with demecolcine treatment (17.4%), even after demecolcine treatment. Our results demonstrate that porcine SSC are a desirable donor cell type for production of SCNT pig embryos and that demecolcine increases production efficiency of cloned embryos by inhibiting rupture of nuclei donor SSC during SCNT.

Abstract
In this study, a modified method of handmade cloning (m-HMC), which had been originally developed in sheep, was used for somatic cell nuclear transfer (SCNT) in the dromedary camel. The unique feature of m-HMC over current SCNT methods lies in the use of a simple device (a finely drawn micropipette made of Pasteur pipette) for chemically-assisted enucleation of oocytes under a stereomicroscope with improved efficiency and ease of operation. Using this system, the throughput of cloned embryo reconstitution was increased over 2-fold compared to the control SCNT method (c-NT). Stepwise measurement of reactive oxygen species (ROS) revealed that method, steps, and duration of SCNT all influenced oxidative activity of oocytes, but their impact were not similar. Specifically, UV-assisted oocyte enucleation was identified as the major source of ROS production, which explained significantly higher total ROS of reconstituted embryos in c-NT compared to m-HMC. Fusion efficiency (95.3±3.3 vs. 75.4±7.6%) and total efficiency of blastocyst development (22.5±3.0 vs. 14.1±4.3%) were significantly higher in m-HMC compared to c-NT, respectively, and blastocysts of transferable quality were obtained in similar rates (41.9±8.2 vs. 48.0±15.2%, respectively). Significance differences were observed in total cell number (155.3±13.6 vs. 123.6±19.5) and trophectoderm (145±9.5 vs. 114.3±15.2), but not inner cell mass (10.3±4.1 vs. 9.3±5.3) counts between blastocysts developed in c-NT compared to m-HMC, respectively. However, expression of key developmental genes (POU5F1, KLF4, SOX2, MYC, and CDX2) was comparable between blastocysts of both groups. The introduced m-HMC method might be a viable approach for efficient production of dromedary camel clones for research and commercial utilization.

Abstract
The efficiencies in producing cloned ruminant embryos and subsequent production of offspring are still low. The study was conducted to produce cloned goat and cattle embryos using inter- and intraspecies SCNT techniques. This study involved 3 different types of donor karyoplast using goat and cattle oocyte as a recipient cytoplast to produce cloned goat and cattle embryos. The results showed that fetal fibroblast cell (FFC) in interspecies SCNT gave significantly higher 2-cell (64.40 vs. 38.43%), 4-cell (54.24 vs. 24.60%), 8-cell (36.82 vs. 14.54%) and morula (22.10 vs. 7.90%) cloned goat embryos than ear fibroblast cell (EFC). As for intraspecies SCNT using cumulus cell (CC) as a donor karyoplast to produce cloned cattle and goat embryos, the values for cleavage rates were not significantly different which were; 53.57 vs. 57.17%, 33.17 vs. 46.40%, 22.15 vs. 27.30% and 11.90 vs. 15.59%, respectively for all embryo stages. Our results showed that cloned goat and cattle embryos could be produced using different types of donor karyoplast in intra- and interspecies SCNT. However, for goat-cattle interspecies SCNT, FFC was more efficient to produce cloned goat embryos compared to EFC.

Abstract
An optimum cell culture medium is used to generate fibroblast cells for cell banking. Here, we describe a method for obtaining higher number of pure fibroblast cells in much shorter duration from skin tissue explants. Two pronged strategy was used, first two different culture media were selected, one for preferential generation of fibroblast cells in primary culture (Human fibroblast specific media- HifibroXL) and another for their faster multiplication in secondary culture (DMEM + Ham's F12). Secondly, tissue explants were cultured not only once but up to six times increasing the generation of primary cells per se. This method initially standardized with buffalo (Bubalus bubalis) skin tissue explants works efficiently with camel (Camelus bactrianus) and horse (Equs caballus). Modified cell culture method increases the efficiency of establishing fibroblast cell banks by reducing the cost both in terms of consumables and human effort. It is well suited for today's fast-paced conservation laboratories.

Abstract
Abstract
Somatic cell nuclear transfer (SCNT) is currently the most efficient and precise method to generate genetically tailored pig models for both agricultural and biomedical research. However, its efficiency is crucially dependent on the source of nuclear donor cells. In this study, we compared the cloning efficiency by using three lines of donor cells that are derived from fetal, newborn and adult fibroblasts of Chinese indigenous Meishan pig. We showed that cleavage rate and blastocyst formation rate of the reconstructed embryos were not significantly different between the fetal (80.7% and 15.6%) and newborn ear skin (77.5% and 12.3%) fibroblast groups (p>0.05), but in both groups these indices were significantly higher than that found in the adult ear skin (70.5% and 8.8%; p<0.05). Reconstructed embryos derived from fetal, newborn, and adult ear skin fibroblasts were transferred to four surrogates, respectively. For the fetal, newborn, and adult ear skin fibroblasts, the number of pregnancies were two (50.0%), two (50.0%), and one (25.0%), respectively, and the number of deliveries were two (50.0%), one (25.0%), and zero (0.0%), respectively. Seven and two cloned piglets were obtained from the fetal and newborn ear skin fibroblasts respectively, while no piglets were obtained from the adult ear skin fibroblasts. Two cloned piglets from the newborn ear skin fibroblasts died shortly after birth because of neonatal asphyxia caused by dystocia. The birth weights of the piglets derived from the fetal and newborn ear skin fibroblasts were 1230.5 and 1310.0g, respectively, which were statistically insignificant (p>0.05), but both were significantly higher than that of the control groups (p<0.05). Microsatellite analyses demonstrated that the genotypes of all cloned piglets were identical to their donor cells. Therefore, cloned pigs were successfully produced using two sources of donor cells isolated from the fetal and newborn ear skin fibroblasts of Meishan piglet, and indicating a better cloning efficiency than that obtained from adult fibroblasts. We concluded that the nuclear donor cell lines have significant impact on the developmental competence of cloned embryos as well as on the cloning efficiency of Meishan pig.

Abstract
Important factors contributing to the well-known high mortality of piglets produced by SCNT are gross malformations of vital organs. The aim of the present retrospective study was to describe malformations found in cloned piglets, transgenic or not, dying or culled before weaning on Day 28. Large White (LW) embryos were transferred to 78 LW recipients, while 72 recipients received Göttingen embryos (67 transgenic and five not transgenic) and 56 received Yucatan embryos (43 transgenic and 13 not transgenic). Overall pregnancy rate was 76%, and there were more abortions in recipients with minipig embryos than in those with LW embryos (26% and 24% vs. 6%). Piglets (n = 815) were born from 128 sows with 6.5 ± 0.4 full-born piglets per litter. The overall rate of stillborn piglets was 21% of all born with the number of stillborn piglets ranging from one to nine in a litter. The mortality of the surviving piglets during the first month was 48%. Thus, altogether 58% of the full-born piglets died before weaning. In 87 of the 128 litters (68%), one to 12 of the piglets showed major or minor malformations. Malformations were found in 232 piglets (29.5% of all born). A single malformation was registered in 152 piglets, but several piglets showed two (n = 58) or more (n = 23) malformations (7.4% and 2.8% of all born, respectively). A significantly higher malformation rate was found in transgenic Göttingen and Yucatan piglets (32% and 46% of all born, respectively) than in nontransgenic LW (17%). There was a gender difference in the transgenic minipigs because male piglets had a higher rate of malformations (49.1%) than females (29.7%). The most common defects in the cloned piglets were in the digestive (12.2%), circulatory (9.4%), reproductive (11.3%), and musculoskeletal (9.1%) systems. Malformations of the musculoskeletal system were most frequent in Göttingen (16.3% vs. approximately 5.5% in the two other breeds), whereas abnormal cardiopulmonary systems were most frequent in Yucatan piglets (26.9% vs. 2.1% in LW and 5.3% in Göttingen). In conclusion, these results show that pig cloning results in a considerable loss of piglets and that many of these can be related to various malformations that all are also seen in noncloned piglets. Because approximately half of the cloned piglets still survive, even with eventual unknown minor malformations, use of pigs as models for human diseases is still realistic. However, continued efforts are needed to further reduce the level of malformations.

Abstract
The effect of technical steps of somatic cell nuclear transfer (SCNT) on different aspects of cloned embryo development was investigated in sheep.In vitro-matured oocytes were enucleated in the presence or absence of zona and reconstituted by three different SCNT techniques: conventional zona-intact (ZI-NT), standard zona-free (ZF-NT) and intracytoplasmic nuclear injection (ICI-NT). Stepwise alterations in nuclear remodeling events and in mRNA abundances, throughput and efficiency of cloned embryo development and cell allocation of the resulted blastocysts were assessed. Early signs of nuclear remodeling were observed as soon as 2 h post-reconstitution (hpr) for fusion-based methods of nuclear transfer (ZI-NT and ZF-NT) but were not observable until 4 hpr with the ICI-NT method. The relative mRNA abundances ofHSP90AA1(HSP90),NPM2andATPasegenes were not affected by i) presence or absence of zona, ii) oocyte enucleation method and iii) nuclear transfer method. After reconstitution, however, the relative mRNA contents ofPOU5F1(OCT4) with the ZI-NT and ZF-NT methods and ofPAPOLA(PAP) with ZF-NT were significantly lower than those for the ICI-NT method. Zona removal doubled the throughput of cloned blastocyst development for the ZF-NT technique compared with ZI-NT and ICI-NT. Cleavage rate was not affected by the SCNT protocol, whereas blastocyst yield rate in ICI-NT technique (17.0±1.0%) was significantly (P<0.05; ANOVA) higher than in ZF-NT (7.1±1.5%) but not in the ZI-NT group (11.2±3.3%). Despite the similarities in total cell number, SCNT protocol changed the distribution of cells in the blastocysts, as ZF-NT-cloned blastocysts had significantly smaller inner cell mass than ZI-NT. These results indicate that technical aspects of cloning may result in the variety of cloning phenotypes.

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
The fate of foreign mitochondrial DNA (mtDNA) following somatic cell nuclear transfer (SCNT) is still controversial. In this study, we examined the transmission of the heteroplasmic mtDNA of gaur donor cells and recipient bovine oocytes to an offspring and aborted and mummified fetuses at various levels during the development of gaur-bovine interspecies SCNT (iSCNT) embryos. High levels of the donor cell mtDNA were found in various tissue samples but they did not have any beneficial effect to the survival of iSCNT offspring. However, the factors on mtDNA inheritance are unique for each iSCNT experiment and depend on the recipient oocyte and donor cell used, which might play an important role in the efficiency of iSCNT.

Abstract
Increased possibility of universality of ooplasmic reprogramming factors resulted in a parallel increased interest to use interspecies somatic cell nuclear transfer (iSCNT) to address basic questions of developmental biology and to improve the feasibility of cell therapy. In this study, the interactions between human somatic cells and ovine oocytes were investigated. Nuclear remodeling events were first observed 3 h post-iSCNT as nuclear swelling, chromosome condensation, and spindle formation. A time-dependent decrease in maturation promoting activity of inactivated reconstructs coincided with increased aberrations in chromosome and spindle organization of the newly developed embryos. The sequence and duration of nuclear remodeling events were irrespective of donor cell type used. Although the majority of the reconstituted embryos arrested before embryonic genome activation (8-16-cell) stage, less than 5% of them could progress beyond transcription-requiring developmental stage and formed blastocyst-like structures with distinct inner cell mass and trophectoderm at days 7 and 8 post-SCNT. Importantly, real-time assessment of three developmentally important genes (Oct4, Sox2, and Nanog) indicated their upregulation in iSCNT blastocysts. Blastocyst-derived outgrowths had alkaline phosphatase activity that was lost upon passage. Collectively, this study introduced ovine oocyte as a credible cytoplast for remodeling and reprogramming of human somatic cells back to the embryonic stage and provided a platform for further studies to unravel possible differences exist between reprogramming ability of oocytes of different mammalian species.

Abstract
PURPOSE To investigate the effect of epigenetic modification on pattern, time and capacity of transcription activation of POU5F1, the key marker of pluripotency, in cloned bovine embryos. METHODS Bovine fibroblasts were stably transfected with POU5F1 promoter-driven enhanced green fluorescent protein (EGFP). This provided a visible marker to investigate the effect of post-activation treatment of cloned bovine embryos with trichostatin A (TSA) on time and capacity of POU5F1 expression and its subsequent effect on in vitro development of cloned bovine embryos. RESULTS Irrespective of TSA treatment, POU5F1 expression was not detected until 8-16 cell stage, but was detected in both inner cell mass and trophectoderm at the blastocyst stage. TSA treatment significantly increased POU5F1 expression, and the yield and quality of cloned embryo development compared to control. CONCLUSION The POU5F1 expression of cloned embryos is strictly controlled by the stage of embryo development and may not be altered by TSA-mediated changes occur in DNA-methylation and histone-acetylation of the genome.

Abstract
5-Aza-2'-deoxycytidine (AzC), trichostatin A (TSA), and its natural mimetic, sodium butyrate (NaB), are antineoplastic drugs that can modify the epigenetic status of donor cells prior to somatic cell nuclear transfer (SCNT). In this study, we used fibroblast cells treated with these drugs to investigate the direct and indirect effects of induced changes in DNA methylation and acetylation of the lysine 9 residue of histone H3 (H3K9). Additionally, we assayed cellular characteristics (cell growth, cell proliferation, cell cycle progression, and apoptosis) and SCNT efficiency in response to these drugs as well as monitoring these effects 24 h after removing the drugs. We observed the following: (1) AzC, TSA, and NaB all showed dose-dependent effects on different cellular characteristics; (2) TSA and NaB induced H3K9 hyperacetylation accompanied by DNA hypermethylation, whereas AzC induced DNA hypomethylation with no effect on H3K9 hyperacetylation; (3) TSA and NaB improved cloning efficiency, whereas AzC reduced it; and (4) unlike AzC, the effects of TSA and NaB on cellular characteristics and SCNT efficiency were reversed following drug removal. Our results indicate that somatic cells treated with TSA and NaB show better survival and recovery rates following the removal of these drugs. Moreover, H3K9 hyperacetylation (induced with TSA and NaB), but not DNA hypomethylation (induced with AzC), favors cloning efficiency.

Abstract
In this study, fibroblast cells were stably transfected with mouse POU5F1 promoter-driven enhanced green fluorescent protein (EGFP) to investigate the effect of S-adenosylhomocysteine (SAH), the reversible non-toxic inhibitor of DNA-methyltransferases (DNMTs), at different intervals post-fusion on in vitro development of cloned bovine embryos. Treatment with SAH for 12 hr resulted in 54.6 ± 7.7% blastocyst production, which was significantly greater than in vitro fertilized embryos (IVF: 37.2 ± 2.7%), cloned embryos treated with SAH for 72 hr (31.0 ± 7.6%), and control cloned embryos (34.6 ± 3.6%). The fluorescence intensities of the EGFP-POU5F1 reporter gene at all intervals of SAH treatment, except of 72 hr, were significantly higher than control somatic cell nuclear transfers (SCNT) embryos. The intensity of DNA-methylation in cloned embryos treated with SAH for 48 hr was similar to that of IVF embryos, and was significantly lower than the other SCNT groups. The levels of H3K9 acetylation in all SCNT groups were significantly lower than IVF embryos. Real-time PCR analysis of gene expression revealed significantly higher expression of POU5F1 in cloned versus IVF blastocysts. Neither embryo production method (SCNT vs. IVF) nor the SAH treatment interval affected expression of the BCL2 gene. Cloned embryos at all intervals of SAH treatment, except for 24 hr, had significantly increased VEGF transcript compared to IVF and control SCNT embryos. It was suggested that the time interval of DNMT inhibition may have important consequences on different in vitro features of bovine SCNT, and the improving effects of DNMT inhibition on developmental competency of cloned embryos are restricted to a specific period of time preceding de novo methylation.
