Genome-wide methylome pattern predictive network analysis reveal mesenchymal stem cell's propensity to undergo cardiovascular lineage. 3 Biotech 2022; 12:12.

Abstract
Mesenchymal stem cells (MSCs) differentiation toward cardiovascular lineage prediction using the global methylome profile will highlight its prospective utility in regenerative medicine. We examined the propensity prediction to cardiovascular lineage using 5-Aza, a well-known cardiac lineage inducer. The customized 180 K microarray was performed and further analysis of global differentially methylated regions by Ingenuity pathway analysis (IPA) in both MSCs and 5-AC-treated MSCs. The cluster enrichment tools sorted differentially enriched genes and further annotated to construct the interactive networks. Prediction analysis revealed pathways pertaining to the cardiovascular lineage found active in the native MSCs, suggesting its higher propensity to undergo cardiac, smooth muscle cell, and endothelial lineages in vitro. Interestingly, gene interaction network also proposed majorly stemness gene network NANOG and KLF6, cardiac-specific transcription factors GATA4, NKX2.5, and TBX5 were upregulated in the native MSCs. Furthermore, the expression of cardiovascular lineage specific markers such as Brachury, CD105, CD90, CD31, KDR and various forms of ACTIN (cardiac, sarcomeric, smooth muscle) were validated in native MSCs using real time PCR and immunostaining and blotting analysis. In 5-AC-treated MSCs, mosaic interactive networks were observed to persuade towards osteogenesis and cardiac lineage, indicating that 5-AC treatment resulted in nonspecific lineage induction in MSCs, while MSCs by default have a higher propensity to undergo cardiovascular lineage.

Abstract
Cardiovascular disorders (CVDs) are the leading cause of global death, widely occurs due to irreparable loss of the functional cardiomyocytes. Stem cell-based therapeutic approaches, particularly the use of Mesenchymal Stem Cells (MSCs) is an emerging strategy to regenerate myocardium and thereby improving the cardiac function after myocardial infarction (MI). Most of the current approaches often employ the use of various biological and chemical factors as cues to trigger and modulate the differentiation of MSCs into the cardiac lineage. However, the recent advanced methods of using specific epigenetic modifiers and exosomes to manipulate the epigenome and molecular pathways of MSCs to modify the cardiac gene expression yield better profiled cardiomyocyte like cells in vitro. Hitherto, the role of cardiac specific inducers triggering cardiac differentiation at the cellular and molecular level is not well understood. Therefore, the current review highlights the impact and recent trends in employing biological and chemical inducers on cardiac differentiation of MSCs. Thereby, deciphering the interactions between the cellular microenvironment and the cardiac inducers will help us to understand cardiomyogenesis of MSCs. Additionally, the review also provides an insight on skeptical roles of the cell free biological factors and extracellular scaffold assisted mode for manipulation of native and transplanted stem cells towards translational cardiac research.

Abstract
Somatic cell nuclear transfer (SCNT) is a powerful technique, although challenging, to study reprograming into the totipotent state of differentiated nuclei in mammals. This procedure was initially applied in farm animals, then rodents, and more recently in primates. Nuclear transfer of embryonic stem cells is known to be more efficient, but many types of somatic cells have now been successfully reprogramed with this procedure. Moreover, SCNT reprograming is more effective on a per cell basis than induced Pluripotent Stem Cells (iPSC) and provides interesting clues regarding the underlying processes. In this chapter, we describe the protocol of nuclear transfer in mouse that combines cell cycle synchronization of the donor cells, enucleation of metaphase II oocyte and Piezo-driven injection of a donor cell nucleus followed by activation of the reconstructed embryos and nonsurgical transfer into pseudo-pregnant mice. Moreover, this protocol includes two facultative steps to erase the epigenetic "memory" of the donor cells and improve chromatin remodeling by histones modifications targeting.

Abstract
Chromatin integrity is essential for cellular homeostasis. Polycomb group proteins modulate chromatin states and transcriptionally repress developmental genes to maintain cell identity. They also repress repetitive sequences such as major satellites and constitute an alternative state of pericentromeric constitutive heterochromatin at paternal chromosomes (pat‐PCH) in mouse pre‐implantation embryos. Remarkably, pat‐PCH contains the histone H3.3 variant, which is absent from canonical PCH at maternal chromosomes, which is marked by histone H3 lysine 9 trimethylation (H3K9me3), HP1, and ATRX proteins. Here, we show that SUMO2‐modified CBX2‐containing Polycomb Repressive Complex 1 (PRC1) recruits the H3.3‐specific chaperone DAXX to pat‐PCH, enabling H3.3 incorporation at these loci. Deficiency of Daxx or PRC1 components Ring1 and Rnf2 abrogates H3.3 incorporation, induces chromatin decompaction and breakage at PCH of exclusively paternal chromosomes, and causes their mis‐segregation. Complementation assays show that DAXX‐mediated H3.3 deposition is required for chromosome stability in early embryos. DAXX also regulates repression of PRC1 target genes during oogenesis and early embryogenesis. The study identifies a novel critical role for Polycomb in ensuring heterochromatin integrity and chromosome stability in mouse early development.

Abstract
Oocytes have a remarkable ability to reactivate silenced genes in somatic cells. However, it is not clear how the chromatin architecture of somatic cells affects this transcriptional reprogramming. Here, we investigated the relationship between the chromatin opening and transcriptional activation. We reveal changes in chromatin accessibility and their relevance to transcriptional reprogramming after transplantation of somatic nuclei into Xenopus oocytes. Genes that are silenced, but have pre-existing open transcription start sites in donor cells, are prone to be activated after nuclear transfer, suggesting that the chromatin signature of somatic nuclei influences transcriptional reprogramming. There are also activated genes associated with new open chromatin sites, and transcription factors in oocytes play an important role in transcriptional reprogramming from such genes. Finally, we show that genes resistant to reprogramming are associated with closed chromatin configurations. We conclude that chromatin accessibility is a central factor for successful transcriptional reprogramming in oocytes. ATAC-seq reveals chromatin accessibility changes during reprogramming in oocytes Genes with open promoters are preferentially activated during reprogramming Transcription factors play a role in transcriptional reprogramming in oocytes Closed chromatin is associated with reprogramming-resistant genes

Abstract
Differentiation of Wharton's Jelly-Mesenchymal Stem cells (WJ-MSCs) into cardiomyocytes (CMs) in vitro has been reported widely although contradictions remain regarding the maturation of differentiated MSCs into fully functioning CMs. Studies suggest that use of epigenetic modifiers like 5'Azacytidine (5-AC) in MSCs de-methylates DNA and results in expression of cardiac-specific genes (CSGs). However, only partial expression of the CSG set leads to incomplete differentiation of WJ-MSCs to CMs. We used the Agilent 180 K human DNA methylation microarray on WJ-MSCs, 5-AC treated WJ-MSCs and human cardiac tissue (hCT) to analyze differential DNA methylation profiles which were then validated by bisulfite sequencing PCR (BSP). BSP confirmed that only a limited number of CSGs were de-methylated by 5-AC in WJ-MSCs. It also revealed that hCT displays a methylation profile similar to promoter regions of CSG in untreated WJ-MSCs. Thus, the presence of hypo-methylated CSGs indicates that WJ-MSCs are ideal cell types for cardiomyogenic differentiation.

Abstract
Improving somatic cell nuclear transfer (SCNT) efficiency is challenging, and trichostatin A (TSA) has been implemented to improve this technique, but it does not work for porcine and monkey SCNT. Thus, a meta-analysis was done to understand the relationship between TSA and mouse SCNT. Published articles were collected using PubMed and ScienceDirect from 2000 to 2018. Total 15 studies were included that suggest TSA can improve SCNT mouse blastocyst formation and live birth. Most TSA effects studied were on histone deacetylase (HDACs), hence the impacts of TSA on the cytoplasm, specifically cancer signaling pathways, endoplasmic reticulum, and HDACs localization were investigated. It is likely that TSA benefits mouse SCNT because the nucleus is easy to remove. Using fluorescent labeling to remove nuclei and TSA incorporation, SNCT may be improved for pig and monkey studies.

Abstract
An increasing number of studies have revealed that histone deacetylase (HDAC) mediated histone deacetylation is important for mammalian oocyte development. However, nonselective HDAC inhibitors (HDACi) were applied in most studies; the precise functions of specific HDAC classes during meiosis are poorly defined. In this study, the class IIa-specific HDACi MC1568 was used to reveal a crucial role of class IIa HDACs in the regulation of histone deacetylation during porcine oocyte meiosis. Besides, the functions of HDACs and histone acetyltransferases in regulating the balance of histone acetylation/deacetylation were also confirmed during oocyte maturation. After the validation of nontoxicity of MC1568 in maturation rate, spindle morphology, and chromosome alignment, effects of MC1568 on developmental competence of porcine somatic cell nuclear transfer (SCNT) embryos were evaluated, and data indicated that treatment with 10 μM MC1568 for 12 hours following electrical activation significantly enhanced the blastocyst rate and cell numbers. Moreover, results showed that optimal MC1568 treatment increased the H4K12 acetylation level in SCNT one cells and two cells. In addition, MC1568 treatment stimulated expression of the development-related genes OCT4, CDX2, SOX2, and NANOG in SCNT blastocysts. Collectively, our investigation uncovered a critical role of class IIa HDACs in the regulation of histone deacetylation during oocyte meiosis. Furthermore, for the first time, we showed that MC1568 can improve the in vitro development of porcine SCNT embryos. These findings provide an alternative HDACi for improving animal cloning efficiency and may shed more light on nuclear reprogramming.

Abstract
Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide and also inflict major burdens on morbidity, quality of life, and societal costs. Considering that CVD preventive medications improve vascular outcomes in less than half of patients (often relative risk reductions range from 12% to 20% compared with placebo), precision medicine offers an attractive approach to refine the targeting of CVD medications to responsive individuals in a population and thus allocate resources more wisely and effectively. New tools furnished by advances in basic science and translational medicine could help achieve this goal. This approach could reach beyond the practitioners 'eyeball' assessment or venerable markers derived from the physical examination and standard laboratory evaluation. Advances in genetics have identified novel pathways and targets that operate in numerous diseases, paving the way for 'precision medicine'. Yet the inherited genome determines only part of an individual's risk profile. Indeed, standard genomic approaches do not take into account the world of regulation of gene expression by modifications of the 'epi'genome. Epigenetic modifications defined as 'heritable changes to the genome that do not involve changes in DNA sequence' have emerged as a new layer of biological regulation in CVD and could advance individualized risk assessment as well as devising and deploying tailored therapies. This review, therefore, aims to acquaint the cardiovascular community with the rapidly advancing and evolving field of epigenetics and its implications in cardiovascular precision medicine.

Abstract
The present study was undertaken to examine the effects of cytoplasmic volume on nucleus
reprogramming and developmental competence of buffalo handmade cloning (HMC) embryos. We
found that both HMC embryos derived from ~150% cytoplasm or ~225% cytoplasm resulted in a
higher blastocyst rate and total cell number of blastocyst in comparison with those from
~75% cytoplasm (25.4 ± 2.0, 27.9 ± 1.6% vs. 17.9 ± 3.1%; 150 ± 10, 169 ± 12 vs. 85 ± 6,
P<0.05). Meanwhile, the proportions of nuclear envelope breakdown
(NEBD) and premature chromosome condensation (PCC) were also increased in the embryos
derived from ~150 or ~225% enucleated cytoplasm compared to those from ~75% cytoplasm.
Moreover, HMC embryos derived from ~225% cytoplasm showed a decrease of global DNA
methylation from the 2-cell to the 4-cell stage in comparison with those of ~75% cytoplasm
(P<0.05). Furthermore, the expression of embryonic genome activation
(EGA) relative genes (eIF1A and U2AF) in HMC embryos
derived from ~225% cytoplasm at the 8-cell stages was also found to be enhanced compared
with that of the ~75% cytoplasm. Two of seven recipients were confirmed to be pregnant
following transfer of blastocysts derived from ~225% cytoplasm, and one healthy cloned
calf was delivered at the end of the gestation period, whereas no recipients were pregnant
after the transfer of blastocysts derived from ~75% cytoplasm. These results indicate that
the cytoplasmic volume of recipient oocytes affects donor nucleus reprogramming, and then
further accounted for the developmental ability of the reconstructed embryos.

Abstract
Changes to the spatial organization of specific chromatin domains such as constitutive heterochromatin have been studied extensively in somatic cells. During early embryonic development, drastic epigenetic reprogramming of both the maternal and paternal genomes, followed by chromatin remodeling at the time of embryonic genome activation (EGA), have been observed in the mouse. Very few studies have been performed in other mammalian species (human, bovine, or rabbit) and the data are far from complete. During this work, we studied the three-dimensional organization of pericentromeric regions during the preimplantation period in the rabbit using specific techniques (3D-FISH) and tools (semi-automated image analysis). We observed that the pericentromeric regions (identified with specific probes for Rsat I and Rsat II genomic sequences) changed their shapes (from pearl necklaces to clusters), their nuclear localizations (from central to peripheral), as from the 4-cell stage. This reorganization goes along with histone modification changes and reduced amount of interactions with nucleolar precursor body surface. Altogether, our results suggest that the 4-cell stage may be a crucial window for events necessary before major EGA, which occurs during the 8-cell stage in the rabbit.

Abstract
This study examines the effects of the histone deacetylation inhibitor scriptaid (SCR) on preimplantation embryo development in vitro and on imprinting gene expression. We hypothesized that SCR would increase histone acetylation levels, enhance embryonic genome activation, and regulate imprinting and X-chromosome inactivation (XCI) in in vitro produced bovine embryos. Zygotes were cultured in vitro in presence or absence of SCR added at different time points. We assessed cleavage and blastocyst rates as well as the quality of blastocysts through: (i) differential cell counts; (ii) survival after vitrification/thawing and (iii) gene expression analysis -including imprinted genes. Blastocyst yields were not different in the control and experimental groups. While no significant differences were observed between groups in total cell or trophectoderm cell numbers, SCR treatment reduced the number of inner cell mass cells and improved the survival of vitrified embryos. Further, genes involved in the mechanism of paternal imprinting (GRB10, GNAS, XIST) were downregulated in presence of SCR compared with controls. These observations suggest SCR prevents deacetylation of paternally imprinting control regions and/or their up-regulation, as these events took place in controls. Whether or not such reductions in XIST and imprinting gene expression are beneficial for post implantation development remains to be clarified.

Abstract
Incomplete epigenetic reprogramming of the genome of donor cells causes poor early and full-term developmental efficiency of somatic cell nuclear transfer (SCNT) embryos. Previous research indicate that inhibition of the histone H3 K79 methyltransferase DOT1L, using a selective pharmacological inhibitor EPZ004777 (EPZ), significantly improved reprogramming efficiency during the generation of mouse induced pluripotent stem cells. However, the roles of DOT1L in porcine nuclear transfer-mediated cellular reprogramming are not yet known. Here we showed that DOT1L inhibition via 0.5 nM EPZ treatment for 12 or 24 h significantly enhanced the blastocyst rate of SCNT embryos and dramatically reduced the level of H3K79me2 during SCNT 1-cell embryonic development. Additionally, H3K79me2 level in the EPZ-treated SCNT embryos was similar to that in in vitro fertilized embryos, suggesting that DOT1L-mediated H3K79me2 is a reprogramming barrier to early development of porcine SCNT embryos. qRT-PCR analysis further demonstrated that DOT1L inactivation did not change the expression levels of DOT1L itself but increased the expression levels of POU5F1, LIN28, SOX2, CDX2 and GATA4 associated with pluripotency and early cell differentiation. In conclusion, DOT1L inhibitor improved early developmental efficiency of porcine SCNT embryos probably via inducing the increased expression of genes important for pluripotency and lineage specification.

Abstract
Improving pollen embryogenesis. Despite the agro-economic importance of pollen embryogenesis, the mechanisms underlying this process are still poorly understood. We describe the dynamics of chromatin modifications (histones H3K4me2, H3K9ac, H3K9me2, and H3K27me3) and chromatin marks (RNA polymerase II CDC phospho-Ser5, and CENH3) during barley pollen embryogenesis. Immunolabeling results show that, in reaction to stress, immature pollen rapidly starts reorganizing several important chromatin modifications indicative of a change in cell fate. This new chromatin modification pattern was accomplished within 24 h from whereon it remained unaltered during subsequent mitotic activity. This indicates that cell fate transition, the central element of pollen embryogenesis, is completed early on during the induction process. Application of the histone deacetylase inhibitor trichostatin A stimulated pollen embryogenesis when used on pollen with a gametophytic style chromatin pattern. However, when this drug was administered to embryogenic pollen, the chromatin markers reversed toward a gametophytic profile, embryogenesis was halted and all pollen invariably died.

Abstract
Animal cloning has been achieved in many species by transplanting differentiated cell nuclei to unfertilized oocytes. However, the low efficiencies of cloning have remained an unresolved issue. Here we find that the combination of two small molecules, trichostatin A (TSA) and vitamin C (VC), under culture condition with bovine serum albumin deionized by ion-exchange resins, dramatically improves the cloning efficiency in mice and 15% of cloned embryos develop to term by means of somatic cell nuclear transfer (SCNT). The improvement was not observed by adding the non-treated, rather than deionized, bovine serum. RNA-seq analyses of SCNT embryos at the two-cell stage revealed that the treatment with TSA and VC resulted in the upregulated expression of previously identified reprogramming-resistant genes. Moreover, the expression of early-embryo-specific retroelements was upregulated by the TSA and VC treatment. The enhanced gene expression was relevant to the VC-mediated reduction of histone H3 lysine 9 methylation in SCNT embryos. Our study thus shows a simply applicable method to greatly improve mouse cloning efficiency, and furthers our understanding of how somatic nuclei acquire totipotency. Summary: The optimized culture condition with small molecules is sufficient to allow highly efficient mouse cloning by removing epigenetic barriers to reprogramming.

Effects of the histone deacetylase inhibitor 'Scriptaid' on the developmental competence of mouse embryos generated through round spermatid injection. Hum Reprod 2016; 32:76-87. [PMID: 27864358 DOI: 10.1093/humrep/dew290] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2016] [Revised: 10/18/2016] [Accepted: 11/06/2016] [Indexed: 12/20/2022] Open
Abstract
STUDY QUESTION Can the histone deacetylase inhibitor Scriptaid improve the efficiency of the development of round spermatid injection (ROSI)-fertilized embryos in a mouse model? SUMMARY ANSWER Treatment of ROSI mouse zygotes with Scriptaid increased the expression levels of several development-related genes at the blastocyst stage, resulting in more efficient in vitro development of the blastocyst and an increased birth rate of ROSI-derived embryos. WHAT IS KNOWN ALREADY The full-term development of embryos derived through ROSI is significantly lower than that following ICSI in humans and other species. STUDY DESIGN, SIZE, DURATION Oocytes, spermatozoa and round spermatids were collected from BDF1 (C57BL/6 × DBA/2) mice. For in vitro development experiments, mouse ROSI-derived zygotes were treated with Scriptaid at different concentrations (0, 125, 250, 500 and 1000 nM) and for different exposure times (0, 6, 10, 16 or 24 h). Next, blastocysts of the optimal Scriptaid-treated group and the non-treated ROSI group were separately transferred into surrogate ICR mice to compare in vivo development with the ICSI group (control). Each experiment was repeated at least three times. PARTICIPANTS/MATERIALS, SETTING, METHODS Metaphase II (MII) oocytes, spermatozoa and round spermatids were obtained from sexually mature BDF1 female or male mice. The developmental potential of embryos among the three groups (the ICSI, ROSI and optimal Scriptaid-treated ROSI groups) was assessed based on the rates of obtaining zygotes, two-cell stage embryos, four-cell stage embryos, blastocysts and full-term offspring. In addition, the expression levels of development-related genes (Oct4, Nanog, Klf4 and Sox2) were analysed using real-time PCR, and the methylation states of imprinted genes (H19 and Snrpn) in these three groups were detected using methylation-specific PCR (MS-PCR) sequencing following bisulfite treatment. MAIN RESULTS AND THE ROLE OF CHANCE The in vitro experiments revealed that treating ROSI-derived zygotes with 250 nM Scriptaid for 10 h significantly improved the blastocyst formation rate (59%) compared with the non-treated group (38%) and further increased the birth rates of ROSI-derived embryos from 21% to 40% in vivo. Moreover, in ROSI-derived embryos, the expression of the Oct4, Nanog and Sox2 genes at the blastocyst stage was decreased, but the optimal Scriptaid treatment restored expression to a level similar to their ICSI counterparts. In addition, Scriptaid treatment moderately repaired the abnormal DNA methylation pattern in the imprinting control regions (ICRs) of H19 and Snrpn. LARGE SCALE DATA N/A LIMITATIONS, REASONS FOR CAUTION: Because of the ethics regarding the use of human gametes for ROSI studies, the mouse model was used as an approach to explore the effects of Scriptaid on the developmental potential of ROSI-derived embryos. However, to determine whether these findings can be applied to humans, further investigation will be required. WIDER IMPLICATIONS OF THE FINDINGS Scriptaid treatment provides a new means of improving the efficiency and safety of clinical human ROSI. STUDY FUNDING/COMPETING INTERESTS The study was financially supported through grants from the National Key Research Program of China (No. 2016YFC1304800); the National Natural Science Foundation of China (Nos: 81170756, 81571486); the Natural Science Foundation of Shanghai (Nos: 15140901700, 15ZR1424900) and the Programme for Professor of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning.

Abstract
Developing procedures for the derivation of human pluripotent stem cells (PSCs) gave rise to novel pathways into regenerative medicine research. For many years, stem cells have attracted attention as a potentially unlimited cell source for cellular therapy in neurodegenerative disorders, cardiovascular diseases, and spinal cord injuries, for example. In these studies, adult stem cells were insufficient; therefore, many attempts were made to obtain PSCs by other means. This review discusses key issues concerning the techniques of pluripotent cell acquisition. Technical and ethical issues hindered the medical use of somatic cell nuclear transfer and embryonic stem cells. Therefore, induced PSCs (iPSCs) emerged as a powerful technique with great potential for clinical applications, patient-specific disease modelling and pharmaceutical studies. The replacement of viral vectors or the administration of analogous proteins or chemical compounds during cell reprogramming are modifications designed to reduce tumorigenesis risk and to augment the procedure efficiency. Intensified analysis of new PSC lines revealed other barriers to overcome, such as epigenetic memory, disparity between human and mouse pluripotency, and variable response to differentiation of some iPSC lines. Thus, multidimensional verification must be conducted to fulfil strict clinical-grade requirements. Nevertheless, the first clinical trials in patients with spinal cord injury and macular dystrophy were recently carried out with differentiated iPSCs, encouraging alternative strategies for potential autologous cellular therapies.

Epigenetic modification with trichostatin A does not correct specific errors of somatic cell nuclear transfer at the transcriptomic level; highlighting the non-random nature of oocyte-mediated reprogramming errors. BMC Genomics 2016; 17:16. [PMID: 26725231 PMCID: PMC4698792 DOI: 10.1186/s12864-015-2264-z] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2014] [Accepted: 12/01/2015] [Indexed: 12/27/2022] Open
Abstract
Background The limited duration and compromised efficiency of oocyte-mediated reprogramming, which occurs during the early hours following somatic cell nuclear transfer (SCNT), may significantly interfere with epigenetic reprogramming, contributing to the high incidence of ill/fatal transcriptional phenotypes and physiological anomalies occurring later during pre- and post-implantation events. A potent histone deacetylase inhibitor, trichostatin A (TSA), was used to understand the effects of assisted epigenetic modifications on transcriptional profiles of SCNT blastocysts and to identify specific or categories of genes affected. Results TSA improved the yield and quality of in vitro embryo development compared to control (CTR-NT). Significance analysis of microarray results revealed that of 37,238 targeted gene transcripts represented on the microarray slide, a relatively small number of genes were differentially expressed in CTR-NT (1592 = 4.3 %) and TSA-NT (1907 = 5.1 %) compared to IVF embryos. For both SCNT groups, the majority of downregulated and more than half of upregulated genes were common and as much as 15 % of all deregulated transcripts were located on chromosome X. Correspondence analysis clustered CTR-NT and IVF transcriptomes close together regardless of the embryo production method, whereas TSA changed SCNT transcriptome to a very clearly separated cluster. Ontological classification of deregulated genes using IPA uncovered a variety of functional categories similarly affected in both SCNT groups with a preponderance of genes required for biological processes. Examination of genes involved in different canonical pathways revealed that the WNT and FGF pathways were similarly affected in both SCNT groups. Although TSA markedly changed epigenetic reprogramming of donor cells (DNA-methylation, H3K9 acetylation), reconstituted oocytes (5mC, 5hmC), and blastocysts (DNA-methylation, H3K9 acetylation), these changes did not recapitulate parallel marked changes in chromatin remodeling, and nascent mRNA and OCT4-EGFP expression of TSA-NT vs. CRT-NT embryos. Conclusions The results obtained suggest that despite the extensive reprogramming of donor cells that occurred by the blastocyst stage, SCNT-specific errors are of a non-random nature in bovine and are not responsive to epigenetic modifications by TSA.

Abstract
Nuclear transfer (NT) is a technique used to investigate the development and reprogramming potential of a single cell. DNA methyltransferase-3-like, which has been characterized as a repressive transcriptional regulator, is expressed in naturally fertilized egg and morula/blastocyst at pre-implantation stages. In this study, we demonstrate that the use of Dnmt3l-knockout (Dnmt3l-KO) donor cells in combination with Trichostatin A treatment improved the developmental efficiency and quality of the cloned embryos. Compared with the WT group, Dnmt3l-KO donor cell-derived cloned embryos exhibited increased cell numbers as well as restricted OCT4 expression in the inner cell mass (ICM) and silencing of transposable elements at the blastocyst stage. In addition, our results indicate that zygotic Dnmt3l is dispensable for cloned embryo development at pre-implantation stages. In Dnmt3l-KO mouse embryonic fibroblasts, we observed reduced nuclear localization of HDAC1, increased levels of the active histone mark H3K27ac and decreased accumulation of the repressive histone marks H3K27me3 and H3K9me3, suggesting that Dnmt3l-KO donor cells may offer a more permissive epigenetic state that is beneficial for NT reprogramming.

Abstract
Impaired development of embryos produced by somatic cell nuclear transfer (SCNT) is mostly associated with faulty reprogramming of the somatic nucleus to a totipotent state and can be improved by treatment with epigenetic modifiers. Here we report that addition of 100 μM vitamin C (VitC) to embryo culture medium for at least 16 h post-activation significantly increases mouse blastocyst formation and, when combined with the use of latrunculin A (LatA) during micromanipulation and activation procedures, also development to term. In spite of this, no significant effects on pluripotency (OCT4 and NANOG) or nuclear reprogramming markers (H3K14 acetylation, H3K9 methylation and DNA methylation and hydroxymethylation) could be detected. The use of LatA alone significantly improved in vitro development, but not full-term development. On the other hand, the simultaneous treatment of cloned embryos with VitC and the histone deacetylase inhibitor psammaplin A (PsA), in combination with the use of LatA, resulted in cloning efficiencies equivalent to those of VitC or PsA treatments alone, and the effects on pluripotency and nuclear reprogramming markers were less evident than when only the PsA treatment was applied. These results suggest that although both epigenetic modifiers improve cloning efficiencies, possibly through different mechanisms, they do not show an additive effect when combined. Improvement of SCNT efficiency is essential for its applications in reproductive and therapeutic cloning, and identification of molecules which increase this efficiency should facilitate studies on the mechanism of nuclear reprogramming and acquisition of totipotency.

Abstract
Pretreatment of somatic cells with undifferentiated cell extracts, such as embryonic stem cells and mammalian oocytes, is an attractive alternative method for reprogramming control. The properties of induced pluripotent stem cells (iPSCs) are similar to those of embryonic stem cells; however, no studies have reported somatic cell nuclear reprogramming using iPSC extracts. Therefore, this study aimed to evaluate the effects of porcine iPSC extracts treatment on porcine ear fibroblasts and early development of porcine cloned embryos produced from porcine ear skin fibroblasts pretreated with the porcine iPSC extracts. The Chariot(TM) reagent system was used to deliver the iPSC extracts into cultured porcine ear skin fibroblasts. The iPSC extracts-treated cells (iPSC-treated cells) were cultured for 3 days and used for analyzing histone modification and somatic cell nuclear transfer. Compared to the results for nontreated cells, the trimethylation status of histone H3 lysine residue 9 (H3K9) in the iPSC-treated cells significantly decreased. The expression of Jmjd2b, the H3K9 trimethylation-specific demethylase gene, significantly increased in the iPSC-treated cells; conversely, the expression of the proapoptotic genes, Bax and p53, significantly decreased. When the iPSC-treated cells were transferred into enucleated porcine oocytes, no differences were observed in blastocyst development and total cell number in blastocysts compared with the results for control cells. However, H3K9 trimethylation of pronuclear-stage-cloned embryos significantly decreased in the iPSC-treated cells. Additionally, Bax and p53 gene expression in the blastocysts was significantly lower in iPSC-treated cells than in control cells. To our knowledge, this study is the first to show that an extracts of porcine iPSCs can affect histone modification and gene expression in porcine ear skin fibroblasts and cloned embryos.

Abstract
Nuclear transfer (NT) technique provides a powerful experimental tool to study the mechanisms of reprogramming processes and to derive NT-embryonic stem (ntES) cells from living or frozen animals. The Piezo-driven direct microinjection NT method has proved to be a valid technique to clone mice and other species. In addition, this method has been broadly used as a versatile tool for many fields of mouse micromanipulation. This chapter describes the "one step method" protocol of nuclear transfer in mouse, which combines injection of a donor cell nucleus and enucleation of MII metaphase in a single manipulation procedure. This protocol describes the isolation and collection of oocytes, treatment of donor cells, visualization of spindle-chromosomal complex, direct injection and enucleation, activation of reconstructed embryos and their in vitro culture and transfer into pseudopregnant mice.

Abstract
A common problem in research laboratories that study the mammalian embryo after nuclear transfer is the limited supply of material. For this reason, new methods are continually developed, and existing methods for cells in culture are adapted to suit this peculiar experimental model. Among them is the fluorescent immunodetection. Fluorescent immuno-detection on fixed embryos is an invaluable technique to detect and locate proteins, especially nuclear ones such as modified histones, in single embryos thanks to its specificity and its sensitivity. Moreover, with specific fixation procedures that preserve the 3D shape of the embryos, immunostaining can now be performed on whole-mount embryos. Target proteins are detected by specific binding of first antibody usually nonfluorescent, and revealed with a second antibody conjugated with a fluorochrome directed specifically against the host animal in which the first antibody was produced. The result can then be observed on a microscope equipped with fluorescent detection. Here, we describe the 3D fluorescent immunodetection of epigenetic modifications in mouse embryos. This procedure can be used on nuclear transferred embryos but also on in vivo-collected, in vitro-developed and in vitro-fertilized ones.

Abstract
It is very important for embryologists to understand how parental inherited genomes are reprogrammed after fertilisation in order to obtain good-quality embryos that will sustain further development. In mammals, it is now well established that important epigenetic modifications occur after fertilisation. Although gametes carry special epigenetic signatures, they should attain embryo-specific signatures, some of which are crucial for the production of healthy embryos. Indeed, it appears that proper establishment of different epigenetic modifications and subsequent scaffolding of the chromatin are crucial steps during the first cleavages. This ‘reprogramming’ is promoted by the intimate contact between the parental inherited genomes and the oocyte cytoplasm after fusion of the gametes. This review introduces two main epigenetic players, namely histone post-translational modifications and DNA methylation, and highlights their importance during early embryonic development.

Abstract
Telomere attrition and genomic instability are associated with organism aging. Concerns still exist regarding telomere length resetting in cloned embryos and ntES cells, and possibilities of premature aging of cloned animals achieved by somatic cell nuclear transfer (SCNT). Trichostatin A (TSA), a histone deacetylase inhibitor, effectively improves the developmental competence of cloned embryos and animals, and recently contributes to successful generation of human ntES cells by SCNT. To test the function of TSA on resetting telomere length, we analyzed telomeres in cloned blastocysts and pigs following treatment of SCNT embryos with TSA. Here, we show that telomeres of cloned pigs generated by standard SCNT methods are not effectively restored, compared with those of donor cells, however TSA significantly increases telomere lengths in cloned pigs. Telomeres elongate in cloned porcine embryos during early cleavage from one-cell to four-cell stages. Notably, TSA facilitates telomere lengthening of cloned embryos mainly at morula-blastocyst stages. Knockdown of pTert by shRNA in donor cells reduces telomerase activity in cloned blastocysts but does not abrogate telomere elongation in the TSA-treated embryos (p > 0.05). However, genes associated with recombination or telomerase-independent mechanism of alternative lengthening of telomeres (ALT) Rad50 and BLM show increased expression in TSA-treated embryos. These data suggest that TSA may promote telomere elongation of cloned porcine embryos by ALT. Together, TSA can elongate telomeres in cloned embryos and piglets, and this could be one of the mechanisms underlying improved development of cloned embryos and animals treated with TSA.

Abstract
The purpose of this study was to investigate the effects of the histone deacetylase (HDAC) inhibitor trichostatin A (TSA) on transgene expression and development of porcine transgenic cloned embryos, specifically focusing on effects derived from TSA-treated donor cells or TSA-treated reconstructed embryos. The results showed that TSA treatment on reconstructed embryos modified the acetylation status, which significantly improved the development of porcine somatic cell nuclear transfer (SCNT) embryos in vitro, but not donor cells. Furthermore, the treatment of reconstructed embryos with TSA enhanced expression of the pluripotency-related gene POU5F1 and stimulated expression of the anti-apoptotic gene BCL-2. Enhanced green fluorescent protein (EGFP) mRNA expression of every group dropped drastically from donor cells to blastocysts. Interestingly, TSA is likely to prevent a decline in EGFP expression in nuclear reprogramming of porcine SCNT embryos. However DNA hypomethylation induced by modified histone acetylation of donor cells treated with TSA was significantly more effective in increasing EGFP expression in SCNT blastocysts. In conclusion, the acetylation status of both donor cells and reconstructed embryos modified by TSA treatment increased transgene expression and improved nuclear reprogramming and the developmental potential of porcine transgenic SCNT embryos.

Abstract
Recent studies have shown that DNA damage affects embryo development and also somatic cell reprogramming into induced pluripotent stem (iPS) cells. It has been also shown that treatment with histone deacetylase inhibitors (HDACi) improves development of embryos produced by somatic cell nuclear transfer (SCNT) and enhances somatic cell reprogramming. There is evidence that increasing histone acetylation at the sites of DNA double-strand breaks (DSBs) is critical for DNA damage repair. Therefore, we hypothesized that HDACi treatment enhances cell programming and embryo development by facilitating DNA damage repair. To test this hypothesis, we first established a DNA damage model wherein exposure of nuclear donor cells to ultraviolet (UV) light prior to nuclear transfer reduced the development of SCNT embryos proportional to the length of UV exposure. Detection of phosphorylated histone H2A.x (H2AX139ph) foci confirmed that exposure of nuclear donor cells to UV light for 10 s was sufficient to increase DSBs in SCNT embryos. Treatment with HDACi during embryo culture increased development and reduced DSBs in SCNT embryos produced from UV-treated cells. Transcript abundance of genes involved in either the homologous recombination (HR) or nonhomologous end-joining (NHEJ) pathways for DSBs repair was reduced by HDACi treatment in developing embryos at day 5 after SCNT. Interestingly, expression of HR and NHEJ genes was similar between HDACi-treated and control SCNT embryos that developed to the blastocyst stage. This suggested that the increased number of embryos that could achieve the blastocyst stage in response to HDACi treatment have repaired DNA damage. These results demonstrate that DNA damage in nuclear donor cells is an important component affecting development of SCNT embryos, and that HDACi treatment after nuclear transfer enhances DSBs repair and development of SCNT embryos.

Abstract
Insufficient epigenetic reprogramming of donor nuclei is believed to be one of the most important causes of low development efficiency of mammalian somatic cell nuclear transfer (SCNT). Previous studies have shown that both the in vitro and in vivo development of mouse SCNT embryos could be increased significantly by treatment with various histone deacetylase inhibitors (HDACi), including Trichostatin A, Scriptaid, and m-carboxycinnamic acid bishydroxamide (CBHA), in which only the effect of CBHA has not yet been tested in other species. In this paper we examine the effect of CBHA treatment on the development of porcine SCNT embryos. We have discovered the optimum dosage and time for CBHA treatment: incubating SCNT embryos with 2 μmol/L CBHA for 24 h after activation could increase the blastocyst rate from 12.7% to 26.5%. Immunofluorescence results showed that the level of acetylation at histone 3 lysine 9 (AcH3K9), acetylation at histone 3 lysine 18 (AcH3K18), and acetylation at histone 4 lysine 16 (AcH4K16) was raised after CBHA treatment. Meanwhile, CBHA treatment improved the expression of development relating genes such as pou5f1, cdx2, and the imprinted genes like igf2. Despite these promising in vitro results and histone reprogramming, the full term development was not significantly increased after treatment. In conclusion, CBHA improves the in vitro development of pig SCNT embryos, increases the global histone acetylation and corrects the expression of some developmentally important genes at early stages. As in mouse SCNT, we have shown that nuclear epigenetic reprogramming in pig early SCNT embryos can be modified by CBHA treatment.

Abstract
Histone acetylation is one of the most important posttranslational modifications that contribute to transcriptional initiation and chromatin remodeling. In our previous study, we enhanced sperm chromatin remodeling within the bovine sperm injection-derived androgenentic (SpI-AG) embryos by sperm pretreatment, and thereby improved their early developmental competence. In this study, we found that blastocyst development of SpI-AG embryos could be elevated by the histone deacetylase inhibitor (HDACi). First, we optimized the efficacy of two histone deacetylase inhibitors [trichostatin A (TSA) and Scriptaid (SCR)] in a dose (0, 5, 10, 20, 50, and 100 nM for TSA; 0, 50, 100, 200, 300, and 500 nM for SCR, respectively) and time-dependent (0, 10, 15, 20, and 25 h) manner on the developmental capacity of these embryos. Furthermore, we quantitatively assessed the alterations in histone H3 and H4 overall acetylation levels and blastocyst quality of SpI-AG embryos by immunofluorescence staining. We found a significantly improved morula and blastocyst development rate of SpI-AG embryos at a mild dose of TSA (20 nM) or SCR (200 nM) for 15 h after embryo activation. Furthermore, both HDACi noticeably increased the levels of acetylated histone H3 and H4 in SpI-AG blastocyst embryos, whereas, SCR treatment improved the quality of blastocysts when compared with control group. In conclusion, HDACi is beneficial for early development of bovine SpI-AG embryos and can be used to improve the efficiency of its in vitro production.

Abstract
Abnormal epigenetic reprogramming, such as histone acetylation, might cause low efficiency of interspecies somatic cell nuclear transfer (iSCNT). This study was conducted to evaluate the effects of trichostatin A (TSA) on the developmental competence and histone acetylation of iSCNT embryos reconstructed from cat somatic cells and bovine cytoplasm. The iSCNT cat and parthenogenetic bovine embryos were treated with various concentrations of TSA (0, 25, 50, or 100 nM) for 24 h, respectively, following fusion and activation. Treatment with 50 nM TSA produced significantly higher rates of cleavage and blastocyst formation (84.3% and 4.6%, respectively) of iSCNT embryos than the rates of non-TSA-treated iSCNT embryos (63.8% and 0%, respectively). Similarly, the treatment of 50 nM TSA increased the blastocyst formation rate of parthenogenetic bovine embryos. The acetylation levels of histone H3 lysine 9 (H3K9) in the iSCNT embryos with the treatment of 50 nM TSA were similar to those of in vitro-fertilized embryos and significantly higher (p<0.05) than those of non-TSA-treated iSCNT embryos (control), irrespective of the embryonic development stage (two-cell, four-cell, and eight-cell stages). These results indicated that the treatment of 50 nM TSA postfusion was beneficial for development to the blastocyst stage of iSCNT cat embryos and correlated with the increasing levels of acetylation at H3K9.

Abstract
SummaryInterspecies somatic cell nuclear transfer (iSCNT), a powerful tool in basic scientific research, has been used widely to increase and preserve the population of endangered species. Yak (Bos grunniens) is one of these species. Development to term of interspecies cloned yak embryos has not been achieved, possibly due to abnormal epigenetic reprogramming. Previous studies have demonstrated that treatment of intraspecies cloned embryos with (NaBu) significantly improves nuclear–cytoplasmic reprogramming and viability in vitro. Therefore, in this study, we evaluated the effect of optimal NaBu concentration and exposure time on preimplantation development of yak iSCNT embryos and on the expression patterns of developmentally important genes. The results showed that 8-cell rate, blastocyst formation rate and total cell number increased significantly compared with their untreated counterparts when yak iSCNT embryos were treated with 5 nM NaBu for 12 h after activation, but that the 2-cell stage embryo rate was not significantly different. The treatment of NaBu also increased significantly the expression levels of Oct-4 and decreased the expression levels of HDAC-2, Dnmt-1 and IGF-1; the expression patterns of these genes were more similar to that of their bovine–yak in vitro fertilization (BY-IVF) counterparts. The results described above indicated that NaBu treatment improved developmental competence in vitro and ‘corrected’ the gene expression patterns of yak iSCNT embryos.

Abstract
Until now, the efficiency of animal cloning by somatic cell nuclear transfer (SCNT) has remained low. Efforts to improve cloning efficiency have demonstrated a positive role of trichostatin A (TSA), an inhibitor of deacetylases, on the development of nuclear transfer (NT) embryos in many species. Here, we report the effects of TSA on pre-implantation development of porcine NT embryos. Our results showed that treatment of reconstructed porcine embryos with 50 nmol/L TSA for 24 h after activation significantly improved the production of blastocysts (P < 0.05), while treating donor cells with the same solution resulted in increases in cleavage rates and blastomere numbers (P < 0.05). However, TSA treatment of both donor cells and SCNT embryos did not improve blastocyst production, nor did it increase blastomere numbers. Using indirect immunofluorescence, we found that TSA treatment of NT embryos could improve the reprogramming of histone acetylation at lysine 9 of histone 3 (H3K9) and affect nuclear swelling of transferred nuclei. However, no apparent effect of TSA treatment on H3K9 dimethylation (H3K9me2) was observed. These findings suggest a positive effect of TSA treatment (either treating NT embryos or donor cells) on the development of porcine NT embryos, which is achieved by improving epigenetic reprogramming.

Abstract
The first successful rabbit SCNT was achieved more than one decade ago, yet rabbits remain one of the most difficult species to clone. The present study was designed to evaluate the effects of two histone deacetylase inhibitors (HDACis), namely trichostatin A (TSA) and scriptaid (SCP), on cloning efficiency in rabbits. The in vitro development, acetylation levels of histone H4 lysine 5 (H4K5), and octamer-binding transcription factor 4 (Oct-4) expression patterns of cloned embryos were systemically examined after various HDACi treatments. Supplementation of TSA (50 nM) or SCP (250 nM) in the culture medium for 6 hours improved blastocyst development rates of cloned embryos compared with the treatment without HDACi. The combined treatment with TSA (50 nM) and SCP (250 nM) further enhanced morula (58.6%) and blastocyst (49.4%) rates in vitro. More importantly, compared with single HDACi treatments, embryos with the combined treatment had a higher level of H4K5 and an increased total cell number (203.7 ± 14.4 vs. 158.9 ± 9.0 or 162.1 ± 8.2; P < 0.05) with a better Oct-4 expression pattern in hatching blastocysts, indicating substantially improved embryo quality. This was apparently the first report regarding Oct-4 expression in cloned rabbit embryos. We inferred that most cloned rabbit embryos had an aberrant inner cell mass (ICM) structure accompanied with abnormal spatial distribution of Oct-4 signals. This study demonstrated a synergistic effect of TSA and SCP treatments on cloned rabbit embryos, which might be useful to improve cloning efficiency in rabbits.

Abstract
To investigate the embryonic genome organization upon fertilization and somatic cell nuclear transfer (SCNT), we tracked HP1β and CENP, two well-characterized protein markers of pericentric and centromeric compartments respectively, in four types of embryos produced by rabbit in vivo fertilization, rabbit parthenogenesis, rabbit-to-rabbit, and bovine-to-rabbit SCNT. In the interphase nuclei of rabbit cultured fibroblasts, centromeres and associated pericentric heterochromatin are usually isolated. Clustering into higher-order chromatin structures, such as the chromocenters seen in mouse and bovine somatic cells, could not be observed in rabbit fibroblasts. After fertilization, centromeres and associated pericentric heterochromatin are quite dispersed in rabbit embryos. The somatic-like organization is progressively established and completed only by the 8/16-cell stage, a stage that corresponds to major embryonic genome activation in this species. In SCNT embryos, pericentric heterochromatin distribution typical for rabbit and bovine somatic cells was incompletely reverted into the 1-cell embryonic form with remnants of heterochromatin clusters in 100% of bovine-to-rabbit embryos. Subsequently, the donor cell nuclear organization was rapidly re-established by the 4-cell stage. Remarkably, the incomplete remodeling of bovine-to-rabbit 1-cell embryos was associated with delayed transcriptional activation compared with rabbit-to-rabbit embryos. Together, the results confirm that pericentric heterochromatin spatio-temporal reorganization is an important step of embryonic genome reprogramming. It also appears that genome reorganization in SCNT embryos is mainly dependent on the nuclear characteristics of the donor cells, not on the recipient cytoplasm.

Abstract
We examined effects of treatment with valproic acid (0, 0.2, 1 or 2 mM, VPA), an
inhibitor of class I and IIa histone deacetylases (HDACs), of mouse somatic cell nuclear
transfer (SCNT) embryos for 24 h from 48 h (4-cell stage), 24 h (2-cell stage) or
immediately after oocyte activation on blastocyst formation rates and qualities of the
resultant blastocysts. Blastocyst formation rates (33.4–37.0%) were not improved by VPA
treatments compared with the untreated control (35.1–36.4%). However, immunofluorescence
staining revealed that Oct4 expression levels, evaluated from percentages of embryos
expressing Oct4 strongly and having more than 10 Oct4-positive cells, in blastocysts from
SCNT embryos treated with 1 mM VPA for 24 h from the 4-cell stage (VPA-4C) were highest
among all the groups and that the proportion of cells with a normal nuclear distribution
of histone H3 trimethylated at lysine 27 (H3K27me3), a marker of the state of X-chromosome
inactivation, significantly increased in the VPA-4C group (36.6%) compared with the
control group (12.4%, P<0.05). Treatments with scriptaid and sodium butyrate,
inhibitors of class I and IIa/b HDACs, for 24 h from the 4-cell stage also had beneficial
effects on SCNT blastocysts. These findings indicate that treatment with 1 mM VPA from the
4-cell stage improves the Oct4 expression and nuclear distribution of H3K27me3 in mouse
SCNT blastocysts and suggest that the inhibition of class I and IIa HDACs from the 4-cell
stage plays an important role in these effects.

Abstract
Early embryonic development in mammals is characterized by major changes in the components of the chromatin and its remodeling. The embryonic chromatin and the nuclear organization in the mouse preimplantation embryo display particular features that are dramatically different from somatic cells. These include the highly specific organization of the pericentromeric heterochromatin within the nucleus and the suggested lack of conventional heterochromatin. We postulate that the plasticity of the cells in the early embryo relies on the distinctive heterochromatin features that prevail during early embryogenesis. Here, we review some of these features and discuss recent findings on the mechanisms driving heterochromatin formation after fertilization, in particular, the emerging role of RNA as a regulator of heterochromatic loci also in mammals. Finally, we believe that there are at least three major avenues that should be addressed in the coming years: (i) Is heterochromatin a driving force in development? (ii) Does it have a role in lineage allocation? (iii) How can heterochromatin "regulate" epigenetic reprogramming?

Abstract
Background Embryonic development proceeds through finely tuned reprogramming of the parental genomes to form a totipotent embryo. Cells within this embryo will then differentiate and give rise to all the tissues of a new individual. Early embryonic development thus offers a particularly interesting system in which to analyze functional nuclear organization. When the organization of higher-order chromatin structures, such as pericentromeric heterochromatin, was first analyzed in mouse embryos, specific nuclear rearrangements were observed that correlated with embryonic genome activation at the 2-cell stage. However, most existing analyses have been conducted by visual observation of fluorescent images, in two dimensions or on z-stack sections/projections, but only rarely in three dimensions (3D). Results In the present study, we used DNA fluorescent in situ hybridization (FISH) to localize centromeric (minor satellites), pericentromeric (major satellites), and telomeric genomic sequences throughout the preimplantation period in naturally fertilized mouse embryos (from the 1-cell to blastocyst stage). Their distribution was then analyzed in 3D on confocal image stacks, focusing on the nucleolar precursor bodies and nucleoli known to evolve rapidly throughout the first developmental stages. We used computational imaging to quantify various nuclear parameters in the 3D-FISH images, to analyze the organization of compartments of interest, and to measure physical distances between these compartments. Conclusions The results highlight differences in nuclear organization between the two parental inherited genomes at the 1-cell stage, i.e. just after fertilization. We also found that the reprogramming of the embryonic genome, which starts at the 2-cell stage, undergoes other remarkable changes during preimplantation development, particularly at the 4-cell stage.

Abstract
In mammals, the embryonic genome is transcriptionally inactive after fertilization and embryonic gene expression is initiated during the preimplantation developmental period, during so-called "embryonic genome activation (EGA)". EGA is dependent on the presence of the basal transcriptional machinery components but also on the parental genome reorganization after fertilization. Indeed, during the first cell cycles, the embryonic nuclei undergo intense remodelling that participates in the regulation of embryonic development. Among the mechanisms of this remodeling, it appears that modifications of epigenetic marks are essential especially at the time of embryonic genome activation. This review will focus on DNA methylation and histone modifications such as acetylation or methylation which are important to produce healthy embryos. We will also consider nuclear higher-order structures, such as chromosomes territories and pericentric heterochromatin clusters. The relevance of these chromatin epigenetic modifications has been sustained by the work performed on cloned embryos produced through nuclear transfer of somatic donor cells. It is indeed believed that incomplete reprogramming of the somatic nucleus, in other words, the incomplete re-establishment of the embryonic epigenetic patterns and peculiar nuclear organization may be among the causes of development failure of cloned animals. This will also be discussed in this review.

Abstract
Recently, reprogramming of somatic cells from a differentiated to pluripotent state by overexpression of specific external transcription factors has been accomplished. It has been widely speculated that an undifferentiated state may make donor cells more efficient for nuclear transfer. To test this hypothesis, we derived induced pluripotent stem cells (iPS cells) from several somatic cell lines: mouse embryonic fibroblast (MEF), adult tail tip fibroblast (TTF), and brain neural stem cells (NSCs). Three dimensional (3D)-fluorescent in situ hybridization (FISH) and quantitative-FISH (Q-FISH) were then used to evaluate constitutive (pericentric and telomeric) heterochromatin organization in these iPS cells and in their parental differentiated cells. Here, we show that important nuclear remodeling and telomeres rejuvenation occur in these iPS cells regardless of their parental origin. When we used these cells as donors for nuclear transfer, we produced live-born cloned mice at much higher rates with the iPS-induced cells than with the parental cell lines. Interestingly, we noticed that developmental potential after nuclear transfer could be correlated with telomere length of the donor cells. Altogether, our findings suggest that constitutive heterochromatin organization from differentiated somatic cells can be reprogrammed to the pluripotent state by induction of iPS cells, which in turn support nuclear transfer procedure quite efficiently.

Abstract
Somatic cell nuclear transfer (SCNT) is the injection of a donor nucleus into an enucleated egg. Despite the use of this technology for many years in research, it is still quite inefficient. One of the causes for this is thought to be incorrect or incomplete genome reprogramming. Embryos produced by nuclear transfer (cloned embryos) very often present abnormal epigenetic signatures and irregular chromatin reorganization. Of these two issues, the issue of chromatin rearrangements within the nuclei after transfer is the least studied. It is known that cloned embryos often present pericentromeric heterochromatin clumps very similar to the chromocenters structures present in the donor nuclei. Therefore, it is believed that the somatic nuclear configuration of donor nuclei, especially that of the chromocenters, is not completely lost after nuclear transfer, in other words, not well reprogrammed. To further investigate pericentromeric heterochromatin reorganization after nuclear transfer, we decided to study its rearrangements in cumulus-derived clones using several related epigenetic markers such as H3S10P, H3K9me3, and the double marker H3K9me3S10P. We observed that two of these markers, H3S10P and H3K9me3S10P, are the ones found on the part of the pericentromeric heterochromatin that is remodeled correctly, resembling exactly the embryonic heterochromatin configuration of naturally fertilized embryos. Conversely, H3K9me3 and heterochromatin protein 1 beta (HP1β)-associated protein were also detected in the perinuclear clumps of heterochromatin, making obvious the maintenance of the somatic epigenetic signature within these nuclear regions. Our results demonstrate that H3S10P and H3K9me3S10P could be good candidates for evaluating heterochromatin reorganization following nuclear reprogramming.

Abstract
RATIONALE Although bone marrow endothelial progenitor cell (EPC)-based therapies improve the symptoms in patients with ischemic heart disease, their limited plasticity and decreased function in patients with existing heart disease limit the full benefit of EPC therapy for cardiac regenerative medicine. OBJECTIVE We hypothesized that reprogramming mouse or human EPCs, or both, using small molecules targeting key epigenetic repressive marks would lead to a global increase in active gene transcription, induce their cardiomyogenic potential, and enhance their inherent angiogenic potential. METHOD AND RESULTS Mouse Lin-Sca1(+)CD31(+) EPCs and human CD34(+) cells were treated with inhibitors of DNA methyltransferases (5-Azacytidine), histone deacetylases (valproic acid), and G9a histone dimethyltransferase. A 48-hour treatment led to global increase in active transcriptome, including the reactivation of pluripotency-associated and cardiomyocyte-specific mRNA expression, whereas endothelial cell-specific genes were significantly upregulated. When cultured under appropriate differentiation conditions, reprogrammed EPCs showed efficient differentiation into cardiomyocytes. Treatment with epigenetic-modifying agents show marked increase in histone acetylation on cardiomyocyte and pluripotent cell-specific gene promoters. Intramyocardial transplantation of reprogrammed mouse and human EPCs in an acute myocardial infarction mouse model showed significant improvement in ventricular functions, which was histologically supported by their de novo cardiomyocyte differentiation and increased capillary density and reduced fibrosis. Importantly, cell transplantation was safe and did not form teratomas. CONCLUSIONS Taken together, our results suggest that epigenetically reprogrammed EPCs display a safe, more plastic phenotype and improve postinfarct cardiac repair by both neocardiomyogenesis and neovascularization.

Abstract
Trichostatin A (TSA) has previously been used in somatic cell nuclear transfer (SCNT) to improve the cloning efficiency in several species, which led our team to investigate the effects of TSA on the full-term development of bovine SCNT and gaur-bovine interspecies SCNT (gaur iSCNT; gaur somatic cells as donors and bovine oocytes as recipients) embryos. Treatment with 50 nM TSA for 10 h after fusion had no positive effects on the rates of fusion, cleavage, or the development to eight-cell or morula stages in both bovine SCNT and gaur iSCNT embryos. However, TSA treatment significantly enhanced the blastocyst formation rate in bovine SCNT embryos (44 vs. 32-34% in the TSA-treated and TSA-untreated groups, respectively), but had no effects on gaur iSCNT embryos. The fresh blastocysts derived from bovine SCNT and gaur iSCNT embryos (fresh groups), as well as vitrified bovine SCNT blastocysts (vitrified group), were transferred to bovine recipients. We found that TSA treatment increased the pregnancy rates only in recipients receiving fresh bovine SCNT embryos. In recipients receiving TSA-treated bovine SCNT embryos, three cloned calves from the fresh group and twin cloned calves from the vitrified group were delivered; however, no calf was born from the TSA-untreated bovine SCNT embryos. In contrast, one gaur iSCNT calf was born from a recipient receiving blastocysts from the TSA-untreated group. In summary, TSA improved the preimplantation development and pregnancy rates of bovine SCNT embryos, but did not have any beneficial effect on gaur iSCNT embryos. However, one gaur iSCNT calf reached full-term development.

Abstract
Many tumors metabolise the majority of the glucose that they take up through glycolysis even in the presence of an adequate oxygen supply. Lactate dehydrogenase A (LDH-A) is the critical enzyme that catalyses the transformation of pyruvate to lactate. We demonstrate that LDH-A reduction can suppress the tumorigenicity of intestinal-type gastric cancer (ITGC) cells by downregulating Oct4 both in vitro and in vivo. A statistical analysis of 661 ITGC specimens showed a significant correlation between LDH-A and Oct4 expression. Moreover, patients with low LDH-A/negative Oct4 expression exhibited better overall survival than patients with other combinations. We conclude that the close correlation of LDH-A and Oct4 may offer a promising therapeutic strategy for ITGC.
