Abstract
Cloning by somatic cell nuclear transfer (SCNT) involves the transfer of a somatic nucleus into an enucleated oocyte followed by chemical activation and embryo culture. Further, handmade cloning (HMC) is a simple and efficient SCNT method for large-scale embryo production. HMC does not require micromanipulators for oocyte enucleation and reconstruction since these steps are carried out using a sharp blade controlled by hand under a stereomicroscope. In this chapter, we review the status of HMC in the water buffalo (Bubalus bubalis) and further describe a protocol for the production of buffalo-cloned embryos by HMC and assays to estimate their quality.

Strategies to Improve the Efficiency of Somatic Cell Nuclear Transfer. Int J Mol Sci 2022; 23:ijms23041969.

Abstract
Mammalian oocytes can reprogram differentiated somatic cells into a totipotent state through somatic cell nuclear transfer (SCNT), which is known as cloning. Although many mammalian species have been successfully cloned, the majority of cloned embryos failed to develop to term, resulting in the overall cloning efficiency being still low. There are many factors contributing to the cloning success. Aberrant epigenetic reprogramming is a major cause for the developmental failure of cloned embryos and abnormalities in the cloned offspring. Numerous research groups attempted multiple strategies to technically improve each step of the SCNT procedure and rescue abnormal epigenetic reprogramming by modulating DNA methylation and histone modifications, overexpression or repression of embryonic-related genes, etc. Here, we review the recent approaches for technical SCNT improvement and ameliorating epigenetic modifications in donor cells, oocytes, and cloned embryos in order to enhance cloning efficiency.

Abstract
Abstract
Since the announcement of the birth of the first cloned mammal in 1997, Dolly the sheep, 24 animal species including laboratory, farm, and wild animals have been cloned. The technique for somatic cloning involves transfer of the donor nucleus of a somatic cell into an enucleated oocyte at the metaphase II (MII) stage for the generation of a new individual, genetically identical to the somatic cell donor. There is increasing interest in animal cloning for different purposes such as rescue of endangered animals, replication of superior farm animals, production of genetically engineered animals, creation of biomedical models, and basic research. However, the efficiency of cloning remains relatively low. High abortion, embryonic, and fetal mortality rates are frequently observed. Moreover, aberrant developmental patterns during or after birth are reported. Researchers attribute these abnormal phenotypes mainly to incomplete nuclear remodeling, resulting in incomplete reprogramming. Nevertheless, multiple factors influence the success of each step of the somatic cloning process. Various strategies have been used to improve the efficiency of nuclear transfer and most of the phenotypically normal born clones can survive, grow, and reproduce. This paper will present some technical, biological, and molecular aspects of somatic cloning, along with remarkable achievements and current improvements.

Abstract
Buffaloes are raised by small farm holders primarily as source of draft power owing to its resistance to hot climate, disease, and stress conditions. Over the years, transformation of these animals from draft to dairy was deliberately carried out through genetic improvement program leading to the development of buffalo-based enterprises. Buffalo production is now getting more attention and interest from buffalo raisers due to its socioeconomic impact as well as its contribution to propelling the livestock industry in many developing countries. Reproduction of buffaloes, however, is confronted with huge challenge and concern as being generally less efficient to reproduce compared with cattle due to both intrinsic and extrinsic factors such as poor estrus manifestation, silent heat, marked seasonal infertility, postpartum anestrus, long calving interval, delayed puberty, inherently low number of primordial follicles in their ovaries, high incidence of atresia, and apoptosis. Assisted reproductive technologies (ARTs) are major interventions for the efficient utilization of follicle reserve in buffaloes. The present review focuses on estrus and ovulation synchronization for fixed time artificial insemination, in vitro embryo production, intracytoplasmic sperm injection, cryopreservation of oocytes and embryos, somatic cell nuclear transfer, the factors affecting utilization in various ARTs, and future perspectives in buffaloes.

Abstract
Buffalo is an important farm animal species in South and South-east Asian countries. Cryopreservation allows long-term storage of somatic cells, which can be made available to research communities. This study aimed to 1) establish and cryopreserve somatic cells from elite buffaloes, and 2) share stored somatic cells and their associated data with researchers. To achieve these targets, somatic cells were established successfully from tail-skin biopsies of 17 buffaloes. The informative data such as buffalo details (breed, date of birth, sex, and age at the time of tissue biopsy collection, and production traits), the number of cryovials stored, and freezing dates were recorded in an electronic file and a printed inventory record. The established somatic cells were flat, spindle-shaped morphology, and expressed vimentin (a fibroblast-like cell type marker) and the negative expression of cytokeratin-18 (an epithelial cell type marker). Altogether, we cryopreserved 970 cryovials (0.1 million cells per vial) from two buffalo breeds, namely Murrah and Nili-Ravi (at least 45 cryovials per animal), for cryobanking. Somatic cell nuclear transfer (SCNT) experiments demonstrated the utility of cryopreserved cells to produce cloned buffaloes. Importantly, these cryopreserved somatic cells are made available to scientific communities. This study encourages the cryopreservation of somatic cells of elite farm animals for their utilization in cell-based research.

Abstract
5-Aza-2'-deoxycytidine (5-Aza-dC), an inhibitor of DNA methyltransferases, is an effective treatment for various cancers and has improved the development rate of cloned embryos. Previous studies have reported the effect of 5-Aza-dC on fibroblasts; however, the mechanism whereby 5-Aza-dC affects sika deer granulosa cells and hormone secretion is presently unknown. Here, we showed that the cell cycle after treatment with different doses of 5-Aza-dC was significantly altered. The number of cells in the S phase was significantly increased in response to a concentration of 0.1 μM 5-Aza-dC. The rate of apoptosis was increased when cells were treated with 0.1 μM and 5 μM 5-Aza-dC. We showed that the protein level of H3K9me2 was significantly decreased in response to 5-Aza-dC. The activity levels of DNA methyltransferase were reduced by a moderate dose of 5-Aza-dC. Furthermore, the secretion of E2 and P4 was influenced by different doses of 5-Aza-dC. Our study suggested that 5-Aza-dC affected hormone secretion in sika deer granulosa cells through cell development and epigenetic regulation. The findings of this study lay the foundation for further epigenetic studies in sika deer.

Abstract
The aim of the present study was to isolate somatic cells from semen, a non-invasive source of donor somatic cells, for somatic cell nuclear transfer (SCNT) experiments. The study had two parts: (1) isolation and culture of somatic cells from semen, which was stored at 4°C; and (2) investigating the SCNT competence of semen-derived somatic cells. We successfully cultured somatic cells from freshly ejaculated semen, which was stored for different times (0, 4, 12, 24, 72 and 144h after semen collection) at 4°C, using a Percoll gradient method. Up to 24h storage, 100% cell attachment rates were observed; cell attachment rates of 66% were observed for the 72 and 144h storage groups. The attached cells observed in all groups examined were proliferated (100%). Cultured cells exhibited epithelial cell morphology and culture characteristics, which was further confirmed by positive expression of cytokeratin 18, an epithelial cell-type marker. We compared the SCNT competence of semen-derived epithelial cells and skin-derived fibroblasts. The cleavage rate, blastocyst production rate, total number of cells in blastocysts and the apoptotic index of blastocysts were similar for embryos produced from semen-derived epithelial cells and skin-derived fibroblasts, indicating that semen-derived epithelial cells can serve as donors for SCNT experiments. In conclusion, we demonstrate a method to culture epithelial cells from stored semen, which can be used to produce cloned embryos of breeding bulls, including remote bulls.

Abstract
Semen contains epithelial cells that can be cultured in vitro. For somatic cell nuclear transfer applications, it is essential to know whether clone(s) produced from semen-derived epithelial cells (SedECs) are healthy and reproductively competent. In this study, the semen and fertility profile of a cloned bull (C1) that was produced from a SedEC were compared with its donor (D1) and with two cloned bulls (C2, C3) that were produced from commonly used skin-derived fibroblast cells (SkdFCs). We observed variations in some fresh semen parameters (ejaculated volume and mass motility), frozen-thawed sperm parameters (plasma membrane integrity, and computer-assisted semen analysis (CASA) indices), but values are within the normal expected range. There was no difference in sperm concentration of ejaculated semen and frozen-thawed semen parameters which include sperm motility, percentage of live and normal morphology sperm, and distance traveled through oestrus mucus. Following in vitro fertilization (IVF) experiments, zygotes from C1 had higher (P < 0.05) cleavage rates (81%) than C2, C3, and D1 (71%, 67%, and 75%, respectively); however, blastocyst development per cleaved embryo and quality of produced blastocysts did not differ. The conception rate of C1 was 46% (7/15) and C2 was 50% (8/15) following artificial insemination with frozen-thawed semen. Established pregnancies resulted in births of 7 and 6 progenies sired by C1 and C2, respectively, and all calves show no signs of phenotypical abnormalities. These results showed that semen from a cloned bull derived from SedECs is equivalent to semen from its donor bull and bulls cloned from SkdFCs.

Abstract
The current study investigated the mechanism of mini pig fetal fibroblasts in improving the epigenetic modification and preimplantation development of cloned embryos. The results showed that the increased AcH3K14 level was dose- and time-dependent. Histone hyperacetylation had no significant effect on cell morphology, cell viability, cell cycle, and relative gene (HDAC1, HAT1, DNMT3A, and BAX) expression. The treated cloned embryos had significantly higher development rates and the total nuclei number than the control (27.62 ± 6.94 % vs. 16.14 ± 10.55 %; 43.90 ± 18.39 vs. 33.06 ± 15.87; P < 0.05). The AcH3K14 level in the treated cloned blastocysts was close to that of IVF blastocysts (5.17 ± 0.93 vs. 5.45 ± 1.91, P > 0.05). The gene transcription (CDX2 and OCT4) of the treated cloned blastocysts was significantly up-regulated than the control (3.32 ± 0.51 vs. 2.05 ± 0.30; 1.21 ± 0.18 vs. 0.81 ± 0.09; P < 0.05). The improvement in the cloned embryo development and the partial correction of abnormal acetylation modification were not necessarily related to the cellular characteristics. This could be caused by histone hyperacetylation of mini pig fetal fibroblasts.

Abstract
The reproductive cloning in buffalo in India has been started using a simplified somatic cell nuclear transfer technique named handmade cloning. Since the birth of first cloned female buffalo in 2009, a number of buffalo clones have been produced in India by utilizing different types of donor cells such as ear cells, embryonic stem cells, semen somatic cells and urine somatic cells. The use of buffalo cloning on a large scale is restricted due to low pregnancy rates and poor calf survival. Considerable attempts have been made to improve the overall buffalo cloning efficiency, particularly by modifying epigenetic reprogramming of cloned embryos. Previous studies have demonstrated that chemical epigenetic modifiers such as trichostatin A and 5-aza-2’-deoxycytidine, m-carboxycinnamic acid bishydroxamide can be used to treat donor somatic cells and reconstructed fused embryos to correct the epigenetic reprogramming to enhance the overall cloning efficiency in terms of live birth rates.

Abstract
Somatic cell nuclear transfer (SCNT) technology provides an opportunity to multiply superior animals that could speed up dissemination of favorable genes into the population. In the present study, we attempted to reproduce a superior breeding bull of Murrah buffalo, the best dairy breed of buffalo, using donor cells that were established from tail-skin biopsy and seminal plasma. We studied several parameters such as cell cycle stages, histone modifications (H3K9ac and H3K27me3) and expression of developmental genes in donor cells to determine their SCNT reprogramming potentials. We successfully produced the cloned bull from an embryo that was produced from the skin-derived cell. Growth, blood hematology, plasma biochemistries, and reproductive organs of the produced cloned bull were found normal. Subsequently, the bull was employed for semen production. Semen parameters such as CASA (Computer Assisted Semen Analysis) variables and in vitro fertilizing ability of sperms of the cloned bull were found similar to non-cloned bulls, including the donor bull. At present, we have 12 live healthy progenies that were produced using artificial insemination of frozen semen of the cloned bull, which indicate that the cloned bull is fertile and can be utilized in the buffalo breeding schemes. Taken together, we demonstrate that SCNT can be used to reproduce superior buffalo bulls.

Abstract
DNA demethylation is involved in many biological processes during pre-implantation embryonic development in mammals. To date, the complicated mechanism of DNA demethylation is still not fully understood. Ten-eleven translocation family (TET3, TET1 and TET2), thymine DNA glycosylase (TDG) and DNA methyltransferase 1 (DNMT1) are considered the major protein enzymes of DNA demethylation in pre-implantation embryos. TET3, TET1, TET2, TDG, and DNMT1 contain abundant levels of intrinsically disordered protein regions (IDPRs), which contribute to increasing the functional diversity of proteins. Thus we tried to explore the complicated DNA demethylation in pre-implantation embryos from the intrinsic disorder perspective. These five biological macromolecules all have DNA demethylation-related functional domains. They can work together to fulfill DNA demethylation in pre-implantation embryos through complex protein-protein interaction networks. Intrinsic disorder analysis results showed these proteins were partial intrinsically disordered proteins. Many identifiable disorder-based DNA-binding sites, protein-binding sites and post-translational modification sites located in the intrinsically disordered regions, and DNA demethylation deficiency point mutations in the IDPRs could significantly change the local disorder propensity of these proteins. To the best of our knowledge, this work provides a new viewpoint for studying the mechanism of DNA methylation reprogramming during mammalian pre-implantation embryonic development.

Abstract
Aberrant epigenetic reprogramming is known to be a major cause of inefficient somatic cell nuclear transfer (SCNT) in pigs, and use of epigenetic modification agents, such as DNA methyltransferase inhibitors (DNMTis), is a promising approach for enhancing SCNT efficacy. Here, we attempted to find the optimal condition of zebularine (Zb), a DNMTi, treatment on porcine SCNT embryos during in vitro culture (IVC). As results, treatment with 5 nM Zb for 24 hr showed the highest rate of embryo development to blastocyst compared to other groups (p < .05). Also, the relative intensities of global DNA methylation levels of anti-5-methylcytosine in pseudo-pronuclear (PNC), 2-cell and 4-cell stages were significantly lower in the Zb-treated group (p < .05), however, changes in methylation levels of centromeric satellite repeat were noted only in PNC and blastocyst stages. In addition, significant positive alterations in the relative expression of genes related to pluripotency (OCT4 and SOX2), histone acetylation (HAT1, HDAC1, HDAC2, and HDAC3) and DNA methylation (DNMT1 and DNMT3a) were observed compared to the control (p < .05). In conclusion, we found that Zb could modify DNA methylation levels in the early stages of porcine SCNT embryos and promote their developmental competence.

Abstract
Biobanks of cryopreserved gametes and embryos of domestic animals have been utilized to spread desired genotypes and to conserve the animal germplasm of endangered breeds. In principle, somatic cells can be used for the same purposes, and for reviving of animals, the somatic cells must be suitable for animal cloning techniques, such as somatic cell nuclear transfer. In the present study, we derived and cryopreserved somatic cells from three breeds of riverine and swamp-like type buffaloes and established a somatic cell bank. In total, 350 cryovials of 14 different individual animals (25 cryovials per animal) were cryopreserved and informative data such as breed value, origin, and others were documented. Immunostaining of the established cells against vimentin and cytokeratin suggested a commitment to the fibroblast lineage. In addition, microsatellite analysis was performed and documented for unambiguous parentage verification of clones in the future. Subsequently, the cryopreserved cells were tested for their suitability as nuclear donors (n = 7) using handmade cloning, and the reconstructed embryos were cultured in vitro. The cleavage rates (95.99% ± 2.17% vs. 82.18% ± 2.50%) and blastocyst rates (37.73% ± 1.54% vs. 24.31% ± 1.78%) were higher (p < 0.05) for riverine buffalo cells than that of swamp-like buffalo cells, whereas the total cell numbers of blastocysts (258.16 ± 36.25 vs. 198.16 ± 36.25, respectively) were similar. In conclusion, we demonstrated the feasibility of biobanking of buffalo somatic cells, and that the cryopreserved cells can be used to produce cloned embryos. This study encourages the development of somatic cell biobanks of domestic livestock, including endangered breeds of buffalo, to preserve valuable genotypes for future revitalization by animal cloning techniques.

Abstract
The term animal cloning refers to an asexual mean of reproduction to produce genetically identical copies of any animal without the use of sperm. In India, the cloning of buffalo is well established and clones of the Murrah, the best dairy breed of buffalo, have been produced. The most acclaimed example is the restoration of progeny-tested breeding bull by isolating somatic cells from frozen doses of semen, which were stored for more than a decade in the semen bank. Buffalo bull cloning is considered the best available option to reproduce declared proven bulls and their semen would contribute to accomplishing the demand of ever-growing frozen semen, which is the prime requirement of conventional breeding. This article highlights the importance of buffalo bull cloning and its current status in India.

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
Epigenetic reprogramming is an indispensable process during the course of mammalian development, but aberrant in cloned embryos. The aim of this study was to examine the effect of donor cell treatment with histone deacetylase (HDAC) inhibitor m-carboxycinnamic acid bishydroxymide (CBHA) on cloned embryo development and establish its optimal concentration. Different concentrations of CBHA (2.5, 5.0, 10.0, and 20.0 μM) were used to treat buffalo adult fibroblast cells for 24 hours and effect on cell proliferation, gene expression, and histone modifications was analyzed. Based on these experiments, the best concentration was chosen to determine the effect of enhanced gene activation mark on developmental rates. Among the different concentrations, CBHA at higher concentration (20 μM) shows the sign of apoptosis and stress as indicated by proliferation rate and gene expression data. CBHA treatment significantly decreased the activity of HDACs and increased the level of gene activation mark H3K9ac and H3K4me3, but could not alter the level of H3K27ac. Based on these experiments, 5 μM CBHA was chosen for treatment of donor cells used for the production of cloned embryos. There was no significant difference in cleavage rate between the control and CBHA treatment group (98.5% ± 1.5% vs. 99.0% ± 1.0%), whereas, blastocyst rate markedly improved (46.65% ± 1.94% vs. 57.18% ± 2.68%). The level of H3K9ac and H3K27me3 did not differ significantly in cloned blastocyst produced from either control or CBHA-treated cells. Altogether, these results suggested that donor cell treatment with CBHA supports the reprogramming process and improves the cloned preimplantation development.

Abstract
The first birth of a cloned animal produced through the Handmade cloning (HMC) technique was reported more than 15 years ago in cattle. This method of somatic cell nuclear transfer (SCNT) has subsequently been evolving as a much simpler alternative to the classical micromanipulator-based SCNT. Several farm animal species such as cattle, buffalo, pigs, sheep, and goats have been successfully cloned using HMC. In buffalo, HMC technique is now well established, and several births of cloned calves have been reported by us. Several factors such as source of somatic cells, quality of recipient oocytes, cell cycle stage prior to SCNT, electrofusion and culture conditions, and epigenetic status of somatic cells, have been optimized leading to the production of good quality cloned embryos. The preservation through cloning of proven breeding bulls that have died by producing live offspring using somatic cells isolated from frozen semen as donor cells and birth of a cloned calf from urine-derived cells are impressive examples of the success of HMC in buffalo. In conclusion, HMC is a valued reproductive technique in buffalo that offers the opportunity to make multiple copies of highly valuable animals, particularly proven breeding bulls. In this review, there is a discussion of the advancement of the HMC technique in buffalo and factors responsible for the efficient production of cloned embryos.

Abstract
Ten-eleven translocation 3 (TET3) mediates active DNA demethylation of paternal genomes during mouse embryonic development. However, the mechanism of DNA demethylation in goat embryos remains unknown. In addition, aberrant DNA methylation reprogramming prevalently occurs in embryos cloned by somatic cell nuclear transfer (SCNT). In this study, we reported that TET3 is a key factor in DNA demethylation in goat pre-implantation embryos. Knockdown of Tet3 hindered DNA demethylation at the two- to four-cell stage in goat embryos and decreased Nanog expression in blastocysts. Overexpression of Tet3 in somatic cells can initiate DNA demethylation, reduce 5-methylcytosine level, increase 5-hydroxymethylcytosine level and promote the expression of key pluripotency genes. After SCNT, overexpression of Tet3 in donor cells corrected abnormal DNA hypermethylation of cloned embryos and significantly enhanced in vitro and in vivo developmental rate (P < 0.05). We conclude that overexpression of Tet3 in donor cells significantly improves goat SCNT efficiency.

Abstract
The application of cloning technology on a large scale is limited by very low offspring rate primarily due to aberrant or incomplete epigenetic reprogramming. Trichostatin A (TSA), a histone deacetylase inhibitor, and 5-aza-2'-deoxycytidine (5-aza-dC), an inhibitor of DNA methyltransferases, are widely used for altering the epigenetic status of cloned embryos. We optimized the doses of these epigenetic modifiers for production of buffalo embryos by handmade cloning and examined whether combined treatment with these epigenetic modifiers offered any advantage over treatment with the individual epigenetic modifier. Irrespective of whether donor cells or reconstructed embryos or both were treated with 50 nM TSA +7.5 nM 5-aza-dC, (1) the blastocyst rate was significantly higher (71.6 ± 3.5, 68.3 ± 2.6, and 71.8 ± 2.4, respectively, vs. 43.1 ± 3.4 for controls, p < 0.05); (2) the apoptotic index was lower (5.4 ± 1.1, 9.5 ± 1.0, and 7.4 ± 1.3, respectively, vs. 19.5 ± 2.1 for controls, p < 0.05) and was similar to that of in vitro fertilization blastocysts (6.0 ± 0.8); (3) the global level of H3K18ac was higher (p < 0.01) and that of H3K27me3 lower (p < 0.05) than in controls and was similar among all treatment groups; and (4) the expression level of epigenetic-(HDAC1, DNMT1, and DNMT3a), pluripotency-(OCT4 and NANOG), and development-related (FGF4) genes, but not that of SOX2 and CDX2, was similar among all treatment groups. These results demonstrate that similar levels of beneficial effects can be obtained following treatment of either donor cells or reconstructed embryos or both with the combination of TSA +5-aza-dC. Therefore, there is no advantage in treating both donor cells and reconstructed embryos when the combination of TSA and 5-aza-dC is used.

Abstract
Use of histone deacetylase inhibitors (HDACis) is believed to improve the developmental competence and quality of cloned embryos produced. We examined the effects of treatment of buffalo fibroblasts with valproic acid (VPA), a HDACi on these cells and on embryos produced from them by hand-made cloning. VPA treatment (1.5, 3.0, or 4.5 mM) altered (p < 0.05) the growth characteristics and relative expression level of HDAC1, DNMT1, DNMT3a, P53, and CASPASE3, and the global level of H3K9/14ac, H4K5ac, and H3K18ac but not H3K27me3 in the cells. After the use of VPA-treated donor cells for producing embryos, the cleavage and blastocyst rate, and total cell number were not significantly affected; however, the apoptotic index was lower (p < 0.05) for 3.0 or 4.5 mM VPA group than for 1.5 mM VPA group or the controls. In the cloned blastocysts, the expression level of HDAC1 was higher (p < 0.05) and CASPASE3 was lower (p < 0.05), whereas that of DNMT1, DNMT3a, and P53 and the global level of H3K9/14ac were not significantly affected after VPA treatment of donor cells. In conclusion, these results suggest that VPA treatment of donor cells adversely affects their growth characteristics, increases histone acetylation, and alters gene expression but does not improve production rate of cloned embryos.
