Abstract
The present study aimed to facilitate widespread application of a previously described manual method of somatic cell nuclear transfer (SCNT) by investigating the effects of demecolcine (a microtubule-depolymerizing chemical), cytochalasin-B (a microfilament-depolymerizing chemical: 2.5μg/ml for 15min) and MG-132 (a proteasome inhibitor chemical) on the (i) incidence of cytoplasmic protrusion of MII chromosomes, (ii) improvement of manual oocyte enucleation, and (iii) in vitro and in vivo developmental competence of SCNT embryos in the goat. Following in vitro maturation, around 65% of goat oocytes contained a characteristic cytoplasmic protrusion of MII-chromosomes. Treatment with demecolcine (0.4μg/ml for 30min) significantly increased this rate to 92.2±4.5%. Treatment with MG-132 (2μM for 30min) could not improve this rate when used alone (61.4±11.5%), but when combined with demecolcine (86.4±8.1%). Treatment with cytochalasin-B completely suppressed this rate whenever used, either alone (7.7±5.1%) or in combination with demecolcine (3.9±1.3%). In a direct comparison, there was no significant difference in quantity and quality of embryos propagated by the manual vs. micromanipulation-based methods of SCNT (cleavage: 85.3±4.5 vs. 89.5±8.9%, blastocyst: 19.5±4.3 vs. 24.3±4.4%, grade 1 and 2 blastocyst: 33.8±7.1 vs. 29.5±6.3%, total cell count: 125±11.1 vs. 122±10.5, respectively). Furthermore, development to live kids at term was not significant between the two SCNT methods. From both technical and economical points of view, the overall in vitro and in vivo efficiency of this manual method of SCNT proved it a simple, fast and efficient alternative for large scale production of cloned goats.

Abstract
Assisted reproductive techniques (ARTs) may perturb the pre-/peri-conception microenvironments, which subsequently threaten the health of offspring. This study aimed to investigate the effects of superovulation, vitrification, in vitro culture, and embryo transfer on the expression of epigenetic modulators, imprinted genes, and pluripotency markers in expanded blastocysts and Day-9.5 (D9.5) concepti. Results revealed that 53.4% (8/15) and 86.7% (13/15) of genes in the fetus and placenta, respectively, have similar patterns of transcription in all D9.5 concepti, despite the perturbed mRNA expression observed at the blastocyst stage for each embryo-production technique. These observations indicate a counterbalancing of the abnormal expression pattern analyzed at the blastocyst stage during post-implantation development, particularly when the uterus of a naturally synchronized foster mother is employed. Superovulation resulted in the most abnormal expression patterns compared to other treatment groups, although these same blastocysts were able to develop in a synchronized uterus. Thus, superovulation creates a hormonal environment that negatively affected gene expression and impairs fetal growth more adversely during post-implantation development than other ART protocols, such as in vitro culture, vitrification, or embryo transfer-although each did contribute negatively to the implantation and development process. Together, these results may have implications for treating infertility in humans.

Abstract
To unravel the differential contributions of nuclear-DNA and cytoplasm to the poor 'competence' of oocytes after cryopreservation, reciprocal exchange of metaphase II-spindle chromosomal complex (karyoplast) between vitrified and fresh oocytes was carried out in an ovine animal model. Karyoplast exchange per se was accomplished with high efficiency and in-vitro development of oocytes reconstituted with fresh-karyoplast and vitrified-cytoplast (FK/VC) showed no improvement over VK/VC and control-vitrification oocytes. Blastocyst development of oocytes that were reconstituted with vitrified-karyoplast and fresh-cytoplast (VK/FC) approached that of fresh-controls, however, and was significantly higher than FK/VC, VK/VC, and control-vitrification (all P ≤ 0.05). These results point toward 'cytoplasmic insufficiencies' as the main cause of poor 'competence' of matured oocytes after vitrification.

Abstract
In this study, the effect of the steps involved in zona-free somatic cell nuclear transfer (SCNT) on oocyte transcripts was investigated in sheep. To establish the reliable combined electrical-chemical activation for zona-free oocytes, oocytes were first exposed to an electrical pulse and then treated with 18 chemical activation regimens designed through modifying duration and concentration of ionomycin and 6-dimethyl aminopurine (6-DMAP), which is routinely used for SCNT. Electrofusion-mediated nuclear transfer significantly reduced transcript abundances of CCNB1, POU5F1, NPM2, GMMN, and CX43 compared to intact oocytes. Maximum parthenogenetic blastocyst development was obtained when oocytes were submitted to electric pulse and then to (1) 5 μM ionomycin for 5 or 2.5 min, both followed by 2 h of incubation with 6-DMAP (41.7±1.1, and 42.4±1.4%, respectively), (2) 5 μM ionomycin for 1 min+6-DMAP for 4 h (43.1±1.4%), and (3) 2.5 μM ionomycin for 1 min+6-DMAP for 2 h (42.4±1.4%), with significant differences compared to all the other groups. Statistical assessment of interactions between duration and concentration of ionomycin and duration of 6-DMAP exposure revealed that (1) concentration of ionomycin may be a more important factor than its duration, (2) both a long exposure period and a low concentration of ionomycin had marked decreasing effects on parthenogenetic development of zona-free oocytes, and (3) high duration of exposure to 6-DMAP can reduce parthenogenetic development. Despite an activation preference of parthenogenetic oocytes, a significantly higher rate of cloned blastocyst development was observed when reconstructed oocytes were activated with 5 μM ionomycin for 5 min rather than 2.5 μM ionomycin for 1 min (8.8±2.5 vs. 1.25±2.2%). These results suggested that SCNT steps have determining effects on oocyte transcripts and activation preferences of the reconstituted oocytes compared to intact counterparts. In this sense, reconstituted oocytes may need a higher concentration of ionomycin for a longer period than intact oocytes.

Abstract
In vitro embryo production and embryo vitrification of genetically superior cows that culled inevitably due to health problems can accelerate genetic progress. This study was carried out to investigate whether maternal age and health status effects of high genetic merit cows affect cryosurvival and developmental competence of IVP embryos. In this sense, the effects of ageing and four common culling causes of dairy cows [repeat breeding (RPB), udder problems (UPM), chronic endometritis (CRE), and lameness (LAM)] on in vitro embryo development, and in vivo developmental competence after embryo vitrification were evaluated. The mean number of oocytes obtained per cow did not vary significantly between donors indifferent groups. Cleavage rates in RPB (86.0+/-4.2%), SEN (81.3+/-2.5%) and CRE (77.6+/-6.3%) cows which were comparable to control (95.9+/-1.5%) but were significantly higher than the related rate of UPM donors (50.6+/-2.6%). Importantly, there was no significant difference between the blastocyst rates of different groups. Mean overall survival rate was not different between the groups and was not affected by the blastocyst production rate. There was no significant difference between pregnancy rates of different groups. The results of the present study indicated that in cattle, neither ageing, nor these four diseases affect ovarian potential in terms of the yield and quality of in vitro embryo development.

Abstract
The potential applications of a simplified method of somatic cell nuclear transfer (SCNT) that is improved in both efficiency and throughput is considerable. Technically, a major step of SCNT is to produce large pools of enucleated oocytes (cytoplasts) efficiently, a process that requires considerable micromanipulation skill and expensive equipment. Here, we have developed an efficient and high-throughput method of manual oocyte enucleation using a simple device, a pulled Pasteur pipette, that can be connected to standard zona-free method of embryo reconstitution. Common Pasteur pipettes were pulled on a flame to produce finely drawn pipettes with inner diameters approximately less than half the oocyte diameter (∼50-60 μm), and slightly larger than cytoplasmic protrusion (∼20-30 μm) that was induced after demecolcine treatment of MII-stage oocytes. Oocyte manipulation was performed under a stereomicroscope by either bisecting the oocyte into two approximately equal demioocytes (blind manual enucleation), or by positioning the oocytes so that the cytoplasmic extrusion that contains the MII chromosome mass is removed with the minimum amount of cytoplasm (oriented manual enucleation). The survival rate of the manually enucleated oocytes was 81.4-91.5%, comparable to standard zona-free method of oocyte enucleation (>95%). A total of 80-120 oocytes could be enucleated in 10 min, which was considerably higher than standard zona-free enucleation method. In vitro development rates of cloned embryos derived from manually enucleated cytoplasts with varying cytoplasmic volumes (50%, 95%, and 100%) was comparable, and embryonic developmental rates of the two latter groups were at least as good as standard zona-free method. The manual method of oocyte enucleation described here can be learned and mastered for simple, fast, and cheap production of cloned embryos with comparable efficiency to other available methods.

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

Abstract
In vitro growth of preantral follicles has the potential to produce considerable numbers of competent oocytes for use in medicine, agriculture, and even wildlife conservation. The critical regulatory role of growth factors and hormones in the development of preantral follicles has been established. This study investigated the effect of glial-derived neurotropic factor (GDNF) and kit ligand (KL) on the in vitro development of ovine preantral follicles. Results indicated that both GDNF and KL significantly improved activation of primordial follicles, similar to co-addition of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF), which are commonly used for in vitro follicular development. Importantly, GDNF had a more profound effect on follicle health, development, and differentiation compared with KL alone. Furthermore, the combination of GDNF and KL in the presence of EGF and bFGF had a positive, synergic effect on health, development, and differentiation of preantral follicles, as determined by histological and hormonal assessments. The results of this study may provide a foundation for further studies that will unravel the molecular mechanisms of follicular development to further improve the current status of in vitro preantral follicle culture.

Abstract
In order to investigate whether the kinetics and stage of embryo development affect cryosurvival of in vitro produced bovine embryos, cleaved embryos were categorized in six groups based on their developmental kinetics regarding the stage of embryonic block in bovine (8-16 cell stage): I and II--early (day 2) and late (day 3) 5-8 cell, III and IV--early (day 3) and late (day 4) 8-16 cell, and V and VI--early (day 4) and late (day 5) morula. The cryosurvival and developmental competence of these embryos were compared with each other and also with the corresponding control groups. The potential of 5-8 cell stage embryos to survive vitrification and further develop towards blastocyst stage was significantly lower than vitrified and un-vitrified 8-16 cell and morula stage embryos. These results suggest that, the survival rate and potential of embryos to develop towards blastocyst stage might be affected by the kinetic of the embryo development. Moreover, the results of this study indicated that the optimal stages of early embryo vitrification are post-embryonic block.

Abstract
Substitution of egg yolk with soybean lecithin may reduce hygienic risks in extenders. Though a few studies have been performed on the effect of soybean lecithin in bull, to date evaluation of ram semen in vitro fertility after cryopreservation with use of soybean lecithin has not been studied. This study assessed the effect of 1% or 2% (wt/vol) soybean lecithin (L1 or L2) or 15% or 20% (vol/vol) egg yolk (E15 or E20) supplemented with 5% or 7% glycerol (G5 or G7) in a Tris-based medium for cryopreservation of ram (Oviss arries) semen. Although no significant difference was observed in pattern of capacitation, the best results in terms of sperm motility, viability postthaw, and cleavage rates were observed with L1G7 (51.9+/-4.8%, 48.1+/-3.5%, and 79.6+/-3.9%, respectively) and E20G7 (51.8+/-2.9%, 46.7+/-4.0%, and 72.9+/-6.4%, respectively). Our results also showed that 1% lecithin and 20% egg yolk was superior to 2% lecithin and 15% egg yolk. In terms of cleavage rate, 7% glycerol was superior to 5% glycerol. No significant difference was obtained between groups in terms of blastocysts rate per cleaved embryo. Therefore, we concluded that the optimal concentration of lecithin and egg yolk is 1% and 20%, respectively, along with 7% glycerol. In addition, our results suggest that lecithin can be used as a substitute for egg yolk.

Abstract
Sperm-mediated oocyte activation is a complex procedure, both in steps and duration, not yet been completely mimicked during in vitro studies, e.g., parthenogenesis or somatic cell nuclear transfer. Furthermore, parthenogenetic studies have been recognized as a suitable model for studying activation efficiency for nuclear transfer cloning. This study, therefore, was conducted to develop an optimized artificial activation method, based on bovine cloning. In vitro matured bovine oocytes were initially exposed to electrical pulse, used for cell fusion during cloning, and then treated with 15 temporal sequential combinations of 3 chemical activators [calcium ionophore (CI), strontium (SR) and ethanol (ET)], followed by exposure to a protein kinase inhibitor or used for in vitro fertilization as control group. Treated and naturally fertilized oocytes were further cultured for up to 8 days. Embryo development was scored daily and blastocyst cell counting was carried out using differential staining at day 8 of culture. Among 15 temporal sequential combinations of three chemical activators, the best cleavage rates were associated with double (SR-CI, 84.4%), triple (CI-SR-ET, 79.4%) and single (CI, 73.7%) compounds, respectively, which were not significantly different with each other and with in vitro fertilized (IVF) (85.5%). The highest blastocyst rates were gained with ET-SR (24.5%), SR-CI-ET (20.4%) and CI (24.5%) accordingly which were not significantly different with each other but significantly lower than IVF (47%). Embryo cell counting further confirmed reasonably better quality of blastocysts produced using double, triple and single compounds. Although most of the sequential artificial activation compounds induced high cleavage rate, close to IVF, but this did not assure comparable further embryo development to the blastocyst stage. Nevertheless, the results suggest exposure of in vitro matured bovine oocytes to electrical pulse, followed by exposure to CI-6-dimethylaminopurine (6-DMAP) or ET-SR-6-DMAP could be regarded as the optimal artificial activation protocol for in vitro development of parthenogenic bovine oocytes or as a step for activation protocol in cloning procedure.
