Abstract
The success of Somatic cell nuclear transfer (SCNT) primarily depends on the extent of reprogramming of donor cells genome. The error of reprogramming may lead to inappropriate expression of embryonic genes at any stage of development. Under the present study the relative expression of different genes related to pluripotency (Oct-4 and Nanog), growth factors (IGF-2 and IGF-2R) and DNA methyltransferase gene (Dnmt-1) was evaluated in SCNT embryos at 8-16 cells, morula and blastocyst stages as compared to IVF group. In SCNT, significantly higher degree of relative expression was observed for Oct-4 in morula (1.41) and blastocysts (1.14) as compared to 8-16 cells (referral stage) whereas in IVF, a lower expression was observed at morula (0.82) stage. The expression of Nanog in SCNT embryos was increased significantly in morula (2.23) and decreased subsequently in blastocyst (0.56), whereas it was increased significantly from 8 to 16 cells to morula (1.62) and blastocyst (4.5) of IVF group. The IGF-2 and IGF-2R showed significantly higher expression rates in morula and blastocysts of SCNT (6.56, 5.90 and 1.11, 1.4) and IVF (8.69, 8.25 and 2.96, 3.91) embryos, respectively as compared to referral stage. The expression of Dnmt-1 was significantly higher in SCNT morula (1.29) and blastocyst (1.15) however in IVF, it was similar in 8-16 cells stage and morula but, higher in blastocyst (1.58). The dissimilar pattern of gene expression of SCNT might be a consequence of incomplete reprogramming of donor nucleus which resulted into lower blastocyst rate of SCNT as compared to IVF embryos.

Abstract
The aim of this study was to evaluate if the positive effects of inhibiting histone deacetylase enzymes on cell reprogramming and development of somatic cell nuclear transfer (SCNT) embryos is affected by the cell cycle stage of nuclear donor cells and host oocytes at the time of embryo reconstruction. SCNT embryos were produced with metaphase II (MII) or telophase II (TII) cytoplasts and nuclear donor cells that were either at the G1-0 or G2/M stages. Embryos reconstructed with the different cell cycle combinations were treated or not with the histone deacetylase inhibitor (HDACi) Scriptaid for 15 h and then cultured in vitro for 7 days. Embryos reconstructed with MII-G1-0 and TII-G2/M developed to the blastocyst stage with a higher frequency compared to the other groups, confirming the importance of cell cycle interactions on cell reprogramming and SCNT embryo development. Treatment with HDACi improved development of SCNT embryos produced with MII but not TII cytoplasts, independently of the cell cycle stage of nuclear donor cells. These findings provide evidence that the positive effect of HDACi treatment on development of SCNT embryos depends upon cell cycle interactions between the host cytoplast and the nuclear donor cells.

Abstract
Somatic cloning, also known as somatic cell nuclear transfer (SCNT), is a promising technology which has been expected to rapidly extend the population of elaborately selected breeding boars with superior production performance. Chinese Guike No. 1 pig breed is a novel swine specialized strain incorporated with the pedigree background of Duroc and Chinese Luchuan pig breeds, thus inherits an excellent production performance. The present study was conducted to establish somatic cloning procedures of adult breeding boars from the Chinese Guike No. 1 specialized strain. Ear skin fibroblasts were first isolated from a three-year-old Chinese Guike No. 1 breeding boar, and following that, used as donor cell to produce nuclear transfer embryos. Such cloned embryos showed full in vitro development and with the blastocyst formation rate of 18.4 % (37/201, three independent replicates). Finally, after transferring of 1187 nuclear transfer derived embryos to four surrogate recipients, six live piglets with normal health and development were produced. The overall cloning efficiency was 0.5 % and the clonal provenance of such SCNT derived piglets was confirmed by DNA microsatellite analysis. All of the cloned piglets were clinically healthy and had a normal weight at 1 month of age. Collectively, the first successful cloning of an adult Chinese Guike No. 1 breeding boar may lay the foundation for future improving the pig production industry.

Abstract
Guangxi Huanjiang Xiang pig is a unique miniature pig strain that is originally from Huanjiang Maonan Autonomous County of Guangxi province, China, and shows great potential in agricultural and biomedical research. Although cloning and genetic modification of this pig would enhance its application value, cloning of this strain has not yet been reported. We sought to establish appropriate cloning procedures and produce transgenic embryos in Huanjiang Xiang pigs through the following methods. We isolated fibroblasts from tails of Huanjiang Xiang pig and genetically modified them using Xfect transfection. Fibroblasts, either in non-transgenic or transgenic forms, were used as donor cells for reconstructed embryos by somatic cell nuclear transfer (SCNT), and in vitro development was monitored after the reconstruction. We found no difference in blastocyst formation rate between non-transgenic and transgenic embryos (10.8% vs. 10.3%; P ≥ 0.05). In addition, we tested whether Scriptaid, a widely used histone deacetylase inhibitor, could enhance the in vitro development of Huanjiang Xiang pig cloned embryos. Treatment with 500 nM Scriptaid for 16 h post-activation significantly increased the blastocyst formation rate (26.1% vs. 10.8% for non-transgenic nuclear transfer groups with vs. without the Scriptaid treatment and 28.5% vs. 10.3% for transgenic nuclear transfer groups with vs. without the Scriptaid treatment; P < 0.05). This study provided a basis for further generation of cloned and transgenically cloned Huanjiang Xiang pigs used in agricultural and biomedical research.

Abstract
Abnormal epigenetic reprogramming of donor nuclei after somatic cell nuclear transfer (SCNT) is thought to be the main cause of low cloning efficiencies. A growing body of evidence has demonstrated a positive role of Scriptaid, a histone deacetylase inhibitor (HDACi) that belongs to an existing class of hydroxamic acid-containing HDACis, on the development competence of cloned embryos in many species. The present study investigated the effects of Scriptaid on the development of porcine SCNT embryos in vitro and its mechanism. Treatment with 300 or 500 nM Scriptaid for 20 h after activation significantly increased the percentage of SCNT embryos that developed to the blastocyst stage and the total number of cells per blastocyst and significantly decreased the percentage of apoptotic cells in blastocysts. Scriptaid treatment significantly increased the level of histone H3 acetylated at K9 and the conversion of 5-methylcytosine into 5-hydroxymethylcytosine and significantly decreased the level of histone H3 trimethylated at K9 at the pronuclear stage. As a potential mechanism for the DNA methylation changes, our results showed that the expression of DNA methyltransferase 1 was frequently down-regulated in Scriptaid-treated embryos in comparison with untreated embryos and was inversely correlated to endogenous microRNA-152 (miR-152). Taken together, these findings illustrated a crucial functional crosstalk between miR-152 and DNMT1. Meanwhile, mRNA and protein levels of POU5F1 and CDX2 were increased in Scriptaid-treated embryos. mRNA levels of Caspase3, and Bax were significantly decreased and that of Bcl-xL was significantly increased in Scriptaid-treated embryos. In conclusion, these observations would contribute to uncover the nuclear reprogramming mechanisms underlying the effects of Scriptaid on the improvement of porcine SCNT embryos.

Abstract
It is well known that embryos cultured in a group can create a microenvironment through secretion of autocrine and paracrine factors that can support and improve the embryos' development when compared to the embryos cultured individually. In this study, we used a co-culture system for paracrine communication between different kinds of embryos. The results showed that co-culture of porcine parthenogenetic (PA) embryos significantly improved the in vitro development of cloned (nuclear transfer, NT) embryos. To reveal the possible mechanism of communication between the two groups, we isolated exosomes/microvesicles (EXs/MVs) from the PA embryos conditioned medium (PA-CM) through differential centrifugation and identified them through transmission electron microscope and immunoflourescence against exosomal/membrane marker CD9. Furthermore, these EXs/MVs were found to contain mRNA of pluripotency genes (Oct4, Sox2, Klf4, c-Myc, and Nanog), and the PKH67-labeled EXs/MVs could be internalized by the NT embryos. The current study demonstrates that cloned embryos' developmental competence can be improved through co-culturing with PA embryos and revealed, for the first time, that in vitro-produced embryos can secrete EXs/MVs as a possible communication tool within their microenvironment. Moreover, it provides a new paradigm for embryo-to-embryo communication in vitro.
