Abstract
Horse cloning by somatic cell nuclear transfer (SCNT) is an attractive scientific and commercial endeavor. Moreover, SCNT allows generating genetically identical animals from elite, aged, castrated, or deceased equine donors. Several variations in the horse SCNT method have been described, which may be useful for specific applications. This chapter describes a detailed protocol for horse cloning, thus including SCNT protocols using zona pellucida (ZP)-enclosed or ZP-free oocytes for enucleation. These SCNT protocols are under routine use for commercial equine cloning.

Abstract
Assisted reproduction techniques (ARTs) have become widespread in the equine breeding industry. In particular, the combination of oocyte recovery from live mares followed by IVM and intracytoplasmic sperm injection (ICSI) has increased markedly among the ARTs used with valuable or low-fertility animals. There is currently no consensus among research groups regarding the optimal oocyte maturation period to produce high-quality embryos. In this study, we report the maturation dynamics of equine oocytes at different time points, from 20 to 40h (Experiment 1). In addition, in Experiment 2, equine ICSI blastocysts were produced from oocytes that exhibited early (up to 24h) or late (28-30h) extrusion of the first polar body (PB). Blastocyst rates and diameter were recorded and embryo quality was assessed by analysing the number of apoptotic cells and Yes-associated protein 1 (YAP1) expression. By 20h of IVM, 42% of oocytes were mature, and the remaining oocytes matured within the next 17h of IVM. Although no differences were found in cell apoptosis or the number of YAP1-positive cells between groups exhibiting early and late PB extrusion, embryos from the early group (Group I) exhibited an improved total cell number and blastocyst rate compared to embryos from the late group (Group II) (18.60% vs 10.17% respectively).

Abstract
Introduction Cell plasticity is crucial in cloning to allow an efficient nuclear reprogramming and healthy offspring. Hence, cells with high plasticity, such as multipotent mesenchymal stem cells (MSCs), may be a promising alternative for horse cloning. In this study, we evaluated the use of bone marrow-MSCs (BM-MSCs) as nuclear donors in horse cloning, and we compared the in vitro and in vivo embryo development with respect to fibroblasts. Materials and methods Zona-free nuclear transfer was performed using BM-MSCs (MSC group, n=3432) or adult fibroblasts (AF group, n=4527). Embryos produced by artificial insemination (AI) recovered by uterine flushing and transferred to recipient mares were used as controls (AI group). Results Blastocyst development was higher in the MSC group than in the AF group (18.1% vs 10.9%, respectively; p<0.05). However, pregnancy rates and delivery rates were similar in both cloning groups, although they were lower than in the AI group (pregnancy rates: 17.7% [41/232] for MSC, 12.5% [37/297] for AF and 80.7% [71/88] for AI; delivery rates: 56.8% [21/37], 41.5% [17/41] and 90.1% [64/71], respectively). Remarkably, the gestation length of the AF group was significantly longer than the control (361.7±10.9 vs 333.9±8.7 days), in contrast to the MSC group (340.6±8.89 days). Of the total deliveries, 95.2% (20/21) of the MSC-foals were viable, compared to 52.9% (9/17) of the AF-foals (p<0.05). In addition, the AF-foals had more physiological abnormalities at birth than the MSC-foals; 90.5% (19/21) of the MSC-delivered foals were completely normal and healthy, compared to 35.3% (6/17) in the AF group. The abnormalities included flexural or angular limb deformities, umbilical cord enlargement, placental alterations and signs of syndrome of neonatal maladjustment, which were treated in most cases. Conclusion In summary, we obtained 29 viable cloned foals and found that MSCs are suitable donor cells in horse cloning. Even more, these cells could be more efficiently reprogrammed compared to fibroblasts.

In Vitro and In Vivo Development of Horse Cloned Embryos Generated with iPSCs, Mesenchymal Stromal Cells and Fetal or Adult Fibroblasts as Nuclear Donors. PLoS One 2016; 11:e0164049.

Abstract
The demand for equine cloning as a tool to preserve high genetic value is growing worldwide; however, nuclear transfer efficiency is still very low. To address this issue, we first evaluated the effects of time from cell fusion to activation (<1h, n = 1261; 1-2h, n = 1773; 2-3h, n = 1647) on in vitro and in vivo development of equine embryos generated by cloning. Then, we evaluated the effects of using different nuclear donor cell types in two successive experiments: I) induced pluripotent stem cells (iPSCs) vs. adult fibroblasts (AF) fused to ooplasts injected with the pluripotency-inducing genes OCT4, SOX2, MYC and KLF4, vs. AF alone as controls; II) umbilical cord-derived mesenchymal stromal cells (UC-MSCs) vs. fetal fibroblasts derived from an unborn cloned foetus (FF) vs. AF from the original individual. In the first experiment, both blastocyst production and pregnancy rates were higher in the 2-3h group (11.5% and 9.5%, respectively), respect to <1h (5.2% and 2%, respectively) and 1-2h (5.6% and 4.7%, respectively) groups (P<0.05). However, percentages of born foals/pregnancies were similar when intervals of 2-3h (35.2%) or 1-2h (35.7%) were used. In contrast to AF, the iPSCs did not generate any blastocyst-stage embryos. Moreover, injection of oocytes with the pluripotency-inducing genes did not improve blastocyst production nor pregnancy rates respect to AF controls. Finally, higher blastocyst production was obtained using UC-MSC (15.6%) than using FF (8.9%) or AF (9.3%), (P<0.05). Despite pregnancy rates were similar for these 3 groups (17.6%, 18.2% and 22%, respectively), viable foals (two) were obtained only by using FF. In summary, optimum blastocyst production rates can be obtained using a 2-3h interval between cell fusion and activation as well as using UC-MSCs as nuclear donors. Moreover, FF line can improve the efficiency of an inefficient AF line. Overall, 24 healthy foals were obtained from a total of 29 born foals.

Abstract
Somatic cell nuclear transfer (SCNT) requires large numbers of matured oocytes. In vitro-matured (IVM) oocytes have been used in SCNT in many animals. We investigated the use of IVM oocytes in Rex rabbit SCNT using Rex rabbit ovaries obtained from a local abattoir. The meiotic ability of oocytes isolated from follicles of different diameters was studied. Rex rabbit SCNT was optimized for denucleation, activation, and donor cell synchronization. Rex rabbit oocytes grew to the largest diameter (110 μm) when the follicle diameter was 1.0 mm. Oocytes isolated from <0.5-mm follicles lacked the ability to resume meiosis. More than 90% of these oocytes remained in the germinal vesicle (GV) stage after in vitro culture (IVC) for 18 h. Oocytes isolated from >0.7-mm follicles acquired maturation ability. More than 90% of these oocytes matured after IVC for 18 h. The developmental potential of oocytes isolated from >1-mm follicles was greater than that of oocytes isolated from 0.7- to 1.0-mm follicles. The highest activation rates for IVM Rex rabbit oocytes were seen after treatment with 2.5 μM ionomycin for 5 min followed by 2 mM 6-dimethylaminopurine (6-DMAP) and 5 μg/mL cycloheximide (CHX) for 1 h. Ionomycin induced the chromatin of IVM oocytes to protrude from the oocyte surface, promoting denucleation. Fetal fibroblast cells (FFCs) and cumulus cells (CCs) were more suitable for Rex rabbit SCNT than skin fibroblast cells (SFCs) (blastocyst rate was 35.6 ± 2.2% and 38.0 ± 6.0% vs. 19.7 ± 3.1%). The best fusion condition was a 2DC interval for 1 sec, 1.6 kV/cm voltages, and 40 μsec duration in 0.28 M mannitol. In conclusion, the in vitro maturation of Rex rabbit oocytes and SCNT procedures were studied systematically and optimized in this study.

Abstract
There are few reports on the birth of foals resulting from equine adult somatic cell nuclear transfer (NT). On evaluation of reports of 28 live-born adult somatic-cell NT (clone) foals, 3 died within 2 weeks of birth of complications. Approximately 50 % of all reported cloned foals had complications, some requiring aggressive supportive care. The most common abnormalities reported were neonatal maladjustment syndrome, enlarged umbilical remnant, and angular deformity of the forelimbs, similar to problems described in cloned cattle. In contrast, large offspring syndrome and gross abnormalities of the fetal membranes which are described in cloned cattle are not reported in cloned foals. Reports of the health of foals produced by nuclear transfer suggest that NT foals should be treated aggressively as at-risk foals until all parameters are normal.
