Abstract
In the application of reproductive science to conservation breeding, it has long been assumed that artificial insemination using frozen thawed sperm would be the default technology. This has always been problematic considering the wide range of tolerance to freeze thawing among vertebrate sperm. Furthermore, those providing leadership for genome banking should be proactive to preserve maximum genetic diversity, however, for many species there is little or no sperm motility after thawing of cryopreserved sperm. In this review article, there is the contention that a much wider range of tissues should be banked, and the range of evolving advanced reproductive and developmental technologies should be considered for conservation breeding programs, to realize the maximum opportunities of genome banking to contribute to conservation of animal species.

Abstract
Cloned mammals can be achieved through somatic cell nuclear transfer (SCNT), which involves reprogramming of differentiated somatic cells into a totipotent state. However, low cloning efficiency hampers its application severely. Cloned embryos have the same DNA as donor somatic cells. Therefore, incomplete epigenetic reprogramming accounts for low development of cloned embryos. In this review, we describe recent epigenetic barriers in SCNT embryos and strategies to correct these epigenetic defects and avoid the occurrence of abnormalities in cloned animals.

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
Animal cloning is an important technique used to produce clones from valuable farm animals, to rescue animals in risk of extinction, and for producing transgenic animals. The objective of this work was to evaluate the effects of refrigeration on bovine ear skin as a strategy to transport biological material for long periods of time to isolate viable fibroblasts. Ears from eight cows were collected after death and stored for 30 days at 5°C. On days 0, 2, 4, 7, 14, 21, and 30, skin biopsies were cultured in vitro for fibroblast isolation. The time for first fibroblast outgrowth, time to reach 100% confluence. and cell concentration before freezing were observed for each period. In addition, plasma membrane integrity, cell apoptosis, and necrosis in cells were evaluated through fluorescent colorant combination in a flow cytometer from all periods after thawing. Fibroblasts obtained after 30 days of storage, considered a critical period, were tested for embryo production using nuclear transfer (NT) with micromanipulators. All time points allowed for cell culture. The time of cell growth onset was longer in samples refrigerated for 14, 21, and 30 days. The time to reach confluence also increased with longer refrigeration periods. Cells from day 0 reached confluence in 24 ± 2 days, while day 30 cells took 31 ± 0 days. Cell concentration and viability dropped with increased storage time and freezing/thawing, respectively. It was found that a long period of sample storage results in cell damage, making cultivation more difficult and decreasing cell viability post-thawing and cell concentration. However, when cells from day 30 were used as nuclei donors in NT, a 26.05% blastocyst rate after 7 days in culture was obtained. In conclusion, refrigeration at 5°C was shown to be efficient in maintaining viable tissue for up to 30 days, and fibroblasts isolated can be used for cloned embryo production.

Abstract
Somatic cell nuclear transfer (SCNT) provides a unique opportunity to reproduce animals with superior genetics. Viable cell lines are usually established from tissues collected by biopsy from living animals in the SCNT program. In the present study, tissues were collected and preserved from a suddenly deceased champion camel. We established cell lines from these decade-old tissues and used them as nuclear donors. After 42 h of in vitro maturation, 68.00 ± 2.40% of oocytes reached the metaphase II (M II) stage while 87.31 ± 2.57% in vivo collected oocytes were matured at collection (p < 0.05). We observed a higher blastocyst formation rate when in vivo matured oocytes (43.45 ± 2.07%) were used compared to in vitro matured oocytes (21.52 ± 1.74%). The live birth rate was 6.45% vs. 16.67% for in vitro and in vivo matured oocytes, respectively. Microsatellite analysis of 13 camel loci revealed that all the SCNT-derived offspring were identical to each other and with their somatic cell donor. The present study succeeded in the resurrection of 11 healthy offspring from the decade-old vitrified tissues of a single somatic cell donor individual using both in vitro and in vivo matured oocytes.

Abstract
Abstract
The development of effective approaches for not only the in vitro maturation (IVM) of heifer/cow oocytes and their extracorporeal fertilization (IVF) but also the non-surgical collection and transfer of bovine embryos has given rise to optimizing comprehensive in vitro embryo production (IVP) technology and improving other assisted reproductive technologies (ART s), such as cattle cloning by embryo bisection, embryonic cell nuclear transfer (ECNT) and somatic cell nuclear transfer (SCNT). The primary goal of the present paper is to demonstrate the progress and achievements in the strategies utilized for embryonic cell cloning and somatic cell cloning in cattle. Moreover, the current article is focused on recognizing and identifying the suitability and reliability of bovine cloning techniques for nutritional biotechnology, agri-food and biopharmaceutical industry, biomedical and transgenic research and for the genetic rescue of endangered or extinct breeds and species of domesticated or wild-living artiodactyl mammals (even-toed ungulates) originating from the family Bovidae.

Extranuclear Inheritance of Mitochondrial Genome and Epigenetic Reprogrammability of Chromosomal Telomeres in Somatic Cell Cloning of Mammals. Int J Mol Sci 2021; 22:ijms22063099.

Abstract
The effectiveness of somatic cell nuclear transfer (SCNT) in mammals seems to be still characterized by the disappointingly low rates of cloned embryos, fetuses, and progeny generated. These rates are measured in relation to the numbers of nuclear-transferred oocytes and can vary depending on the technique applied to the reconstruction of enucleated oocytes. The SCNT efficiency is also largely affected by the capability of donor nuclei to be epigenetically reprogrammed in a cytoplasm of reconstructed oocytes. The epigenetic reprogrammability of donor nuclei in SCNT-derived embryos appears to be biased, to a great extent, by the extranuclear (cytoplasmic) inheritance of mitochondrial DNA (mtDNA) fractions originating from donor cells. A high frequency of mtDNA heteroplasmy occurrence can lead to disturbances in the intergenomic crosstalk between mitochondrial and nuclear compartments during the early embryogenesis of SCNT-derived embryos. These disturbances can give rise to incorrect and incomplete epigenetic reprogramming of donor nuclei in mammalian cloned embryos. The dwindling reprogrammability of donor nuclei in the blastomeres of SCNT-derived embryos can also be impacted by impaired epigenetic rearrangements within terminal ends of donor cell-descended chromosomes (i.e., telomeres). Therefore, dysfunctions in epigenetic reprogramming of donor nuclei can contribute to the enhanced attrition of telomeres. This accelerates the processes of epigenomic aging and replicative senescence in the cells forming various tissues and organs of cloned fetuses and progeny. For all the above-mentioned reasons, the current paper aims to overview the state of the art in not only molecular mechanisms underlying intergenomic communication between nuclear and mtDNA molecules in cloned embryos but also intrinsic determinants affecting unfaithful epigenetic reprogrammability of telomeres. The latter is related to their abrasion within somatic cell-inherited chromosomes.

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
Successful reproductive cloning depends on obtaining intact donor nuclei from viable cells, ideally isolated by tissue biopsy of a living donor. However, owners and veterinarians often freeze deceased animals, which eventually causes damage to cellular micro-organelles due to the formation of intracellular water crystals. In the present study, we have reported the production of viable cloned puppies using donor nuclei of cells obtained from frozen carcasses. Five cases of deceased and frozen canine specimens were presented to be cloned. Skin fibroblast cell lines were successfully established for four specimens. Significant longer time was needed for the cell growth from frozen tissues (4 days) to reach 80% confluency compared to fresh tissue and frozen tissues frozen for 1- or 2-days. Similarly, SA-βgal positive cells (death cells) were significantly higher in frozen cells for 2- or 4- days compared to samples from fresh or frozen (1 day) sources. The cloning efficiency (CE) and the pregnancy rates (PR) of frozen cells were lower than those obtained from fresh or living donors (CE 2.4 ± 1.8% vs. 0.6 ± 0.3%, PR 21.7 ± 16.1% vs. 7.7 ± 5.3% for fresh vs. frozen, respectively). Here we demonstrate is the possibility to produce healthy offspring from cell lines obtained from frozen tissue collected post-mortem.

Abstract
Somatic cell nuclear transfer (SCNT) is an important technique for producing cloned animals. It, however, is inefficient when there is use of SCNT for cloned animal production. Cytoplasm injection cloning technology (CICT) was developed to overcome the inefficiencies of SCNT use of this purpose. The use of CICT involves additional cytoplasm fusing with enucleated oocytes to restore the cytoplasmic volume, thus improving the in vitro developmental competence and quality of cloned embryos. In this study, there was application of CICT in cats to improve the in vitro developmental competence of cloned embryos, as well as the production of the offspring. The results of this study were that fusion rate of the cloned embryos with use of the CICT method was greater than that with SCNT (80.0 ± 4.8% compared with 67.8 ± 11.3%, respectively), and more blastocysts developed with use of CICT than SCNT (20.0 ± 2.0% compared with 13.5 ± 5.0%, respectively). The 62 cloned embryos that were produced with use of CICT were transferred into five estrous synchronized recipients, and 151 cloned embryos produced using SCNT were transferred to 13 estrous-synchronized recipients. After the embryo transfer, there was birth from surrogate mothers of one live-born kitten that resulted using SCNT compared with three live-born kittens using CICT. The number of CICT-cloned embryos born was greater than that of SCNT-cloned embryos (4.8 ± 2.3% compared with 0.7 ± 1.3%, P < 0.05). These results indicate that the CICT technique can be used to produce cloned kittens, including endangered feline species.

Assessing the tolerance to room temperature and viability of freeze-dried mice spermatozoa over long-term storage at room temperature under vacuum. Sci Rep 2018; 8:10602. [PMID: 30006561 PMCID: PMC6045625 DOI: 10.1038/s41598-018-28896-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Accepted: 07/02/2018] [Indexed: 01/22/2023] Open
Abstract
Freeze-drying has been frequently used to preserve food and microorganisms at room temperature (RT) for extended periods of time; however, its application to mammalian species is difficult. Here, we developed a method to prolong the stability of freeze-dried (FD) mice spermatozoa at RT for more than one year without using any cryoprotectant agents. Our data showed that maintaining a vacuum in ampoules is critical to ensuring the viability of FD spermatozoa, as the stability of spermatozoa DNA increased when imperfectly vacuumed ampoules were detected using a non-destructive test and eliminated. Finally a large number of healthy offspring were obtained from mice oocytes fertilized with FD spermatozoa stored at RT for more than one year. Although the birth rate from three-month stored spermatozoa was lower than that from one-day stored spermatozoa, no further reduction was observed even in one-year stored spermatozoa. Therefore, FD spermatozoa preserved in this study were highly tolerant to warm temperatures. This method of storage shows a great potential for the preservation of genetic resources of mammalian species, such as genetically-modified mouse strains, without the use of electric power.

Abstract
Long-term preservation of fish fertility is essential for the conservation of endangered fishes. However, cryopreservation techniques for fish oocytes and embryos have not yet been developed. In the present study, functional eggs and sperm were derived from whole rainbow trout that had been frozen in a freezer and stored without the aid of exogenous cryoprotectants. Type A spermatogonia retrieved from frozen-thawed whole trout remained viable after freezing duration up to 1,113 days. Long-term-frozen trout spermatogonia that were intraperitoneally transplanted into triploid salmon hatchlings migrated toward the recipient gonads, where they were incorporated, and proliferated rapidly. Although all triploid recipients that did not undergo transplantation were functionally sterile, 2 of 12 female recipients and 4 of 13 male recipients reached sexual maturity. Eggs and sperm obtained from the salmon recipients were capable of producing donor-derived trout offspring. This methodology is thus a convenient emergency tool for the preservation of endangered fishes.

Abstract
Interspecies somatic cell nuclear transfer (iSCNT) could benefit recovery programs of critically endangered species but must be weighed with the risks of failure. To weigh the risks and benefits, a decision-making process that evaluates progress is needed. Experiments that evaluate the efficiency and efficacy of blastocyst, fetal, and post-parturition development are necessary to determine the success or failure or species-specific iSCNT programs. Here, we use the black-footed ferret (Mustela nigripes) as a case study for evaluating this emerging biomedical technology as a tool for genetic restoration. The black-footed ferret has depleted genetic variation yet genome resource banks contain genetic material of individuals not currently represented in the extant lineage. Thus, genetic restoration of the species is in theory possible and could help reduce the persistent erosion of genetic diversity from drift. Extensive genetic, genomic, and reproductive science tools have previously been developed in black-footed ferrets and would aid in the process of developing an iSCNT protocol for this species. Nonetheless, developing reproductive cloning will require years of experiments and a coordinated effort among recovery partners. The information gained from a well-planned research effort with the goal of genetic restoration via reproductive cloning could establish a 21st century model for evaluating and implementing conservation breeding that would be applicable to other genetically impoverished species.

Abstract
Nuclear transfer is a complex multistep procedure that includes oocyte maturation, cell cycle synchronization of donor
cells, enucleation, cell fusion, oocyte activation and embryo culture. Therefore, many factors are believed to contribute to
the success of embryo development following nuclear transfer. Numerous attempts to improve cloning efficiency have been
conducted since the birth of the first sheep by somatic cell nuclear transfer. However, the efficiency of somatic cell
cloning has remained low, and applications have been limited. In this review, we discuss some of the factors that affect the
developmental ability of somatic cell nuclear transfer embryos in cattle.

Abstract
Successful cloning of animals using somatic cell nuclear transfer requires undamaged nuclear DNA from desired donor cell types. In vitro culture of cells is one way of ensuring nuclear integrity. The goal of this study was to evaluate the limits of postmortem cell survival/culture in refrigerated goat ear skin tissues which could be used for long-term storage and cloning of animals in future. To achieve this, 60 explants from 6 different goats were cultured after 0, 3, 6, 9, 13, 16, 20, 23, 27, 30, 33, 37, and 41 d postmortem and observed under inverted microscope for outgrowth of fibroblast-like cells, after 10-12 d of culture. Explants from all time points including 19% from 41-dpm tissues exhibited outgrowth. However, the percentage of outgrowth positive explants, as well as culture confluence, reduced with increasing postmortem time interval. Cell cultures established from primary outgrowth of 41-dpm tissues when compared for their growth profile with similarly obtained 0-dpm cultures revealed similar growth curve and cell morphology. Cytogenetic analysis of 41-dpm tissue-derived cell populations revealed a normal female karyotype with 60 XX homologous chromosomes indicating genetic stability of the cell population. In conclusion, these results show that refrigerated skin tissue remains alive for more than a month and that the cells derived from such tissues are normal and can be cryopreserved for long-term storage and future cloning of animals with desired genetics.

Abstract
The objective of this study was to determine whether or not reproductive performance in cattle produced by somatic cell nuclear transfer (SCNT) is significantly different from that of their genetic donors. To address this question, we directed two longitudinal studies using different embryo production procedures: (1) superovulation followed by artificial insemination (AI) and embryo collection and (2) ultrasound-guided ovum pick-up followed by in vitro fertilization (OPU-IVF). Collectively, these two studies represent the largest data set available for any species on the reproductive performance of female clones and their genetic donors as measured by their embryo production outcomes in commercial embryo production program. The large-scale study described herein was conducted over a six-year period of time and provides a unique comparison of 96 clones to the 40 corresponding genetic donors. To our knowledge, this is the first longitudinal study on the reproductive performance of cattle clones using OPU-IVF. With nearly 2,000 reproductive procedures performed and more than 9,200 transferable embryos produced, our observations show that the reproductive performance of cattle produced by SCNT is not different compared to their genetic donors for the production of transferable embryos after either AI followed by embryo collection (P = 0.77) or OPU-IVF (P = 0.97). These data are in agreement with previous reports showing that the reproductive capabilities of cloned cattle are equal to that of conventionally produced cattle. In conclusion, results of this longitudinal study once again demonstrate that cloning technology, in combination with superovulation, AI and embryo collection or OPU-IVF, provides a valuable tool for faster dissemination of superior maternal genetics.

Abstract
Animal tissues frozen without cryoprotection are thought to be inappropriate for use as a donor for somatic cell nuclear transfer (SCNT) studies. Cells in tissues that have been frozen without a cryoprotectant are commonly thought to be dead or to have lost genomic integrity. However, in this study we show that the frozen auricular cartilage tissues of anatolian buffalo contain a considerable number of viable healthy cells. The cells in auricular cartilage tissues are resistant to cryo-injury at -80°C. Primary cell cultures were established from defrosted ear tissues which were frozen without cryoprotectant. The growth and functional characteristics of primary cell cultures are characterized according to cell growth curve, cell cycle analysis, karyotype and GAG synthesis. The results indicate that frozen cartilage tissues could be valuable materials for the conservation of species and SCNT technology.

Abstract
Bovine somatic cell nuclear transfer (SCNT) embryos can develop to the blastocyst stage at a rate similar to that of embryos produced by in vitro fertilization. However, the full-term developmental rate of SCNT embryos is very low, owing to the high embryonic and fetal losses after embryo transfer. In addition, increased birth weight and postnatal mortality are observed at high rates in cloned calves. The low efficiency of SCNT is probably attributed to incomplete reprogramming of the donor nucleus and most of the developmental problems of clones are thought to be caused by epigenetic defects. Applications of SCNT will depend on improvement in the efficiency of production of healthy cloned calves. In this review, we discuss problems and recent progress in bovine SCNT.

Abstract
Animal cloning using somatic cell nuclear transfer technology has renewed the interest in postmortem tissue storage, since these tissues can be used to reintroduce the lost genes back into the breeding pool in animal agriculture, preserve the genetic diversity, and revive the endangered species. However, for successful cloning of animals, integrity of nuclear DNA is essential. Cell viability and their potential to in vitro culture ensure nuclear integrity. The aim of this study was to determine the limits of postmortem time interval within which live cells can be recovered from goat skin tissues. To test the postmortem tissue storage limits, we cultured 2-3 mm(2) skin pieces (n = 70) from the ears of three breeds of goats (n = 7) after 0, 2, 4, and 6 days of postmortem storage at 24°C. After 10 days of culture, outgrowth of fibroblast-like cells (>50 cells) around the explants was scored. All the explants irrespective of breed displayed outgrowth of cells on the dish containing fresh tissues (i.e., day 0 of storage). However, the number of explants exhibiting outgrowth reduced with increasing time interval. Only 53.85 % explants displayed outgrowth after 2 days of tissue storage. The number of explants displaying outgrowth was much smaller after 4 (16.67 %) and 6 days (13.3 %) of storage. In general, the number of outgrowing cells per explant, on a given day, also decreased with increasing postmortem storage time interval. To test the differences between cell cultures, we established secondary cultures from one of the goats exhibiting outgrowth of cells after 6 days of tissue storage and compared them to similar cells from fresh tissues. Comparison of both the cell lines revealed similar cell morphology and growth curves and had doubling times of 23.04 and 22.56 h, respectively. These results suggest that live cells can be recovered from goat (and perhaps other animal) tissues stored at room temperature even after 6 days of their death with comparable growth profiles and, thus, can be used for tissue banking for preservation of superior genetics, genetic diversity, and cloning of animals.

Blastocysts cloned from the Putian Black pig ear tissues frozen without cryoprotectant at -80 and -196 degrees Celsius for 3 yrs. Theriogenology 2012; 78:1166-70. [PMID: 22626772 DOI: 10.1016/j.theriogenology.2012.03.038] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2011] [Revised: 03/24/2012] [Accepted: 03/25/2012] [Indexed: 10/28/2022]
Abstract
The Putian Black pig, as one of elite cultivars of endemic species in China, has been on the verge of extinction and urgently needs protection. Somatic cell nuclear transfer (SCNT) and noncryoprotected frozen tissue technology have successfully resurrected several mammalian species. Therefore, this study explored the primary feasibility of conserving this breed using a combination of both technologies. Skin tissues obtained from the ears of adult Putian Black boars were frozen without cryoprotectant at -20, -80, or -196 °C and stored for 3 yrs. Primary cell culture, passage and subculture were performed on frozen samples after being rapidly thawed at 39 °C and on fresh pig ear tissues (control). Cloned embryos were reconstructed using fibroblasts (from frozen and fresh tissues) with enucleated oocytes. Live cell lines were obtained from tissues frozen at -80 and at -196 °C and appeared to have normal proliferative activity after passage; furthermore, they directed cloned embryos to develop to the blastocyst stage after nuclear transfer. We concluded that the population of Putian Black pig might be increased in the future by transferring cloned blastocysts into synchronized recipient pigs.

Abstract
Technologies for vitally labeling cells with fluorescent dyes have advanced remarkably. However, to excite fluorescent dyes currently requires powerful illumination, which can cause phototoxic damage to the cells and increases the cost of microscopy. We have developed a filter system to excite fluorescent dyes using a conventional transmission microscope equipped with a halogen lamp. This method allows us to observe previously invisible cell organelles, such as the metaphase spindle of oocytes, without causing phototoxicity. Cells remain healthy even after intensive manipulation under fluorescence observation, such as during bovine, porcine and mouse somatic cell cloning using nuclear transfer. This method does not require expensive epifluorescence equipment and so could help to reduce the science gap between developed and developing countries.

Abstract
Many observations have been made on cloned embryos and on adult clones by somatic cell nuclear transfer (SCNT), but it is still unclear whether the progeny of cloned animals is presenting normal epigenetic status. Here, in order to accumulate the information for evaluating the normality of cloned cattle, we analyzed the DNA methylation status on satellite I region in blastocysts obtained from cloned cattle. Embryos were produced by artificial insemination (AI) to non-cloned or cloned dams using semen from non-cloned or cloned sires. After 7 days of AI, embryos at blastocyst stage were collected by uterine flushing. The DNA methylation levels in embryos obtained by using semen and/or oocytes from cloned cattle were similar to those in in vivo embryos from non-cloned cattle. In contrast, the DNA methylation levels in SCNT embryos were significantly higher (P < 0.01) than those in in vivo embryos from non-cloned and cloned cattle, approximately similar to those in somatic cells used as donor cells. Thus, this study provides useful information that epigenetic status may be normal in the progeny of cloned cattle, suggesting the normality of germline cells in cloned cattle.

Abstract
Live animals have been produced recently from animal tissues preserved for decades at frozen temperatures with or without cryoprotectants. However, the tissues in these studies were cryopreserved within few hours of animal death to obtain culturable live cells as nuclear donors. How long the tissues can be left unfrozen after animal death, without losing the viability and potential to in vitro culture with comparable morphology and proliferative rate as the fresh tissues, is not completely understood. To understand this phenomenon, ear skin samples from individual sheep (n=3) were procured from slaughter plant and stored at 4 °C. After various intervals (2, 8, 24, 32, 48, and 56 h after slaughter), 2-3 mm(2) pieces (n=10) of skin samples were cultured for 12 d on two dishes (60 mm) for each sheep. Outgrowth of fibroblast-like cells was observed as early as day 4 of culture and was visible on dishes of all time points including 56 h by day 10. The number of outgrowing cells decreased with increasing time interval between animal slaughter and culture initiation. Secondary cultures were successfully established for all the time points. All cultures proliferated well and were apparently normal. Passage 2 cultures of 2 h and 56 h interval for one of the three sheep were compared for their growth pattern and proliferation rates. The population doubling time of 2 h and 56 h intervals was 33.12 and 34.8 h, respectively, and both the lines exhibited similar cell morphology and an "S"-shaped growth curve. These results suggest that skin tissues of sheep and perhaps other animal species with superior traits are effectively preserved at cellular level at least for 56 h at normal refrigerating conditions, without need of complicated cryopreservatives/cryotanks that are usually not available at small farms.

Abstract
Animals with a targeted disruption of genes can be produced by somatic cell nuclear transfer (SCNT). However, difficulties in clonal selection of somatic cells with a targeted mutation often result in heterogeneous nuclear donor cells, including gene-targeted and non-targeted cells, and impose a risk of producing undesired wildtype cloned animals after SCNT. In addition, the efficiency of cloning by SCNT has remained extremely low. Most cloned embryos die in utero, and the few that develop to term show a high incidence of postnatal death and abnormalities. In the present study, resurrection of an alpha-1,3-galactosyltransferase (αGT) gene-targeted miniature pig by recloning using postmortem ear skin fibroblasts was attempted. Three cloned piglets were produced from the first round of SCNT, including one stillborn and two who died immediately after birth due to respiratory distress syndrome and cardiac dysfunction. Among the three piglets, two were confirmed to be αGT gene-targeted. Fibroblasts derived from postmortem ear skin biopsies were used as nuclear donor cells for the second round of SCNT, and a piglet was produced. As expected, PCR and Southern analyses confirmed that the piglet produced from recloning was αGT gene-targeted. Currently, the piglet is fourteen months of age, and no overt health problems have been observed. Results from the present study demonstrate that loss of an invaluable animal, such as a gene-targeted miniature pig, may be rescued by recloning, with assurance of the desired genetic modification.

Abstract
It has now been 13 years since the first cloned mammal Dolly the sheep was generated from somatic cells using nuclear transfer (SCNT). Since then, this technique has been considered an important tool not only for animal reproduction but also for regenerative medicine. However, the success rate is still very low and the mechanisms involved in genomic reprogramming are not yet clear. Moreover, the NT technique requires donated fresh oocyte, which raises ethical problems for production of human cloned embryo. For this reason, the use of induced pluripotent stem cells for genomic reprogramming and for regenerative medicine is currently a hot topic in this field. However, we believe that the NT approach remains the only valid way for the study of reproduction and basic biology. For example, only the NT approach can reveal dynamic and global modifications in the epigenome without using genetic modification, and it can generate offspring from a single cell or even a frozen dead body. Thanks to much hard work by many groups, cloning success rates are increasing slightly year by year, and NT cloning is now becoming a more applicable method. This review describes how to improve the efficiency of cloning, the establishment of clone-derived embryonic stem cells and further applications.

Abstract
Somatic cell nuclear transfer has many potential applications in the fields of basic and applied sciences. However, it has a disadvantage that can never be overcome technically-the inflexibility of the sex of the offspring. Here, we report an accidental birth of a female mouse following nuclear transfer using an immature Sertoli cell. We produced a batch of 27 clones in a nuclear transfer experiment using Sertoli cells collected from neonatal male mice. Among them, one pup was female. This "male-derived female" clone grew into a normal adult and produced offspring by natural mating with a littermate. Chromosomal analysis revealed that the female clone had a 39,X karyotype, indicating that the Y chromosome had been deleted in the donor cell or at some early step during nuclear transfer. This finding suggests the possibility of resuming sexual reproduction after a single male is cloned, which should be especially useful for reviving extinct or endangered species.

Abstract
Here, we report the recovery of cell nuclei from 14,000-15,000 years old mammoth tissues and the injection of those nuclei into mouse enucleated matured oocytes by somatic cell nuclear transfer (SCNT). From both skin and muscle tissues, cell nucleus-like structures were successfully recovered. Those nuclei were then injected into enucleated oocytes and more than half of the oocytes were able to survive. Injected nuclei were not taken apart and remained its nuclear structure. Those oocytes did not show disappearance of nuclear membrane or premature chromosome condensation (PCC) at 1 hour after injection and did not form pronuclear-like structures at 7 hours after injection. As half of the oocytes injected with nuclei derived from frozen-thawed mouse bone marrow cells were able to form pronuclear-like structures, it might be possible to promote the cell cycle of nuclei from ancient animal tissues by suitable pre-treatment in SCNT. This is the first report of SCNT with nuclei derived from mammoth tissues.
