"Which Factors Affect Pregnancy Until Calving and Pregnancy Loss in Buffalo Recipients of in vitro Produced Embryos?". Front Vet Sci 2020; 7:577775. [PMID: 33344525 PMCID: PMC7738327 DOI: 10.3389/fvets.2020.577775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 10/10/2020] [Indexed: 11/13/2022] Open
Abstract
In vitro embryo production and embryo transfer (ET) in buffaloes has been developed for decades. However, most studies are focused on the donor or laboratory improvements, and there is a lack of reports regarding the recipients. Therefore, our aim was to investigate factors associated to pregnancy (P/ET), pregnancy loss (PL), and calving rates in buffalo recipients. The studied factors were season, recipient parity, the synchronization protocol, the CL diameter, asynchrony between the embryo and the recipient, the day of the recipient estrous cycle, the embryo (fresh vs. vitrified), the day of embryo development, and the embryo stage. These retrospective data, from a program of in vitro produced embryos, were analyzed by logistic regression, and the odds ratio was also estimated. Two factors were related to P/ET and the calving rate: (1) progesterone associated to estradiol plus eCG protocol for fixed time ET tended to affect positively P/ET on day 30 (41.9 vs. 36.1%, respectively; P = 0.07; AOR = 1.28) and P/ET on day 60 (37.8 vs. 36.1%, respectively; P = 0.09; AOR = 1.08) compared to the Ovsynch protocol; and (2) the CL diameter (≥14.5 mm) at transfer increased P/ET on day 30 (47.4 vs. 32.5%; P < 0.01; AOR = 1.87) and on day 60 (45.3 vs. 27.7%; P < 0.01; AOR = 2.16), and also the calving rate (37.9 vs. 21.7%; P < 0.01; AOR = 2.20). PL was greater when ET was done in the nonbreeding season compared to the breeding season (PL 30-60: 12.8 vs. 0.0%, P = 0.01; AOR > 999.99; PL 60-calving: 26.8 vs. 3.6%, P = 0.03; AOR = 9.90; and PL 30-calving: 36.2 vs. 3.6%, P = 0.01; AOR = 15.30). In conclusion, the data of our study indicated that the synchronization protocol, the CL diameter, and ET during the breeding season impacted the reproductive efficiency of buffalo recipients.

Importance of lipid metabolism on oocyte maturation and early embryo development: Can we apply what we know to buffalo? Anim Reprod Sci 2019; 211:106220. [PMID: 31785645 DOI: 10.1016/j.anireprosci.2019.106220] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 10/08/2019] [Accepted: 10/23/2019] [Indexed: 12/19/2022]
Abstract
The knowledge about the biological events that regulate lipid metabolism in oocytes and embryos in buffalo is scarce. Lipogenesis, lipolysis, transport and oxidation of fatty acids (FAs) occur in gametes and embryonic cells of all mammalian species, as an intrinsic component of energy metabolism. In oocytes and cumulus cells, degradation of lipids is responsible for the production of ATP that is essential for the metabolic processes that lead to oocyte maturation in in vivo and in vitro culture conditions. Similarly, throughout embryo development, blastomeres have the capacity to use exogenous and/or endogenous lipid reserves to serve as an energy source necessary for early embryonic development. In addition, supplementation of culture media with L-carnitine to promote lipid metabolism during in vitro oocyte maturation and early embryonic development leads to an improved embryo quality. The limited scientific evidence available in buffalo indicates there is relatively greater oocyte lipid content as compared with many other species that undergoes a dynamic distribution during folliculogenesis and follicle maturation and that has a positive effect on oocyte maturation and embryo development when there is L-carnitine supplementation of the media. Advances in the understanding of the biological peculiarities of lipid metabolism, and the consequences of its alteration on the quality of buffalo gametes and embryos, therefore, are necessary to design specific culture media and laboratory procedures as a strategy to increase in vitro-derived embryo production rates.

Evaluation of factors involved in the failure of ovum capture in superovulated buffaloes. Theriogenology 2018; 122:102-108. [PMID: 30245332 DOI: 10.1016/j.theriogenology.2018.09.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2018] [Revised: 09/04/2018] [Accepted: 09/10/2018] [Indexed: 02/06/2023]
Abstract
The aim of this work was to evaluate factors affecting ovum capture in superovulated buffaloes, by comparing the morphological features of pre-ovulatory follicles and oocytes, the intrafollicular and plasmatic steroid profile, as well as the expression of genes involved in cumulus expansion and steroid cascade in granulosa cells (GCs) and that of genes involved in contraction-relaxation of the oviduct between superovulated and synchronized buffaloes. Italian Mediterranean Buffalo cows were either synchronized by Ovsynch (n = 25) and superovulated (n = 10) with conventional FSH protocol and sacrificed 18 h after last GnRH. Antral follicular count, recovery rate and oocyte quality were recorded, and plasma and follicular fluid were collected for steroid profile determination. In addition, in 10 animals (5/group), GCs were collected to analyse the mRNA expression of gonadotropin receptors (LHR and FSHR) and genes involved in steroid synthesis, as the cytochrome P450 family 19 (CYP19A1) and the steroidogenic acute regulatory protein (STAR). Moreover, oviducts were collected to evaluate the mRNA expression of estrogen receptor 1 (ER1) and the progesterone receptor (PGR), the vascular endothelial growth factor (VEGF) and the VEGF receptors, i.e. the kinase insert domain receptor (FLK1) and the fms related tyrosine kinase 1 (FLT1). No differences were recorded in steroids plasma concentration between synchronized and superovulated animals whereas intrafollicular E2 and P4 concentrations decreased in superovulated group (63.2 ± 10.6 vs 30.3 ± 5.9 ng/mL of E2 and 130.1 ± 19.8 vs 71.6 ± 8.5 ng/mL of P4, respectively in synchronized and superovulated animals; P < 0.05). Interestingly, both the recovery rate (85.7% vs 56.6%, respectively in synchronized and in superovulated animals; P < 0.05) and the percentage of oocytes exhibiting proper cumulus expansion (75% vs 28.1%, respectively in synchronized and in superovulated animals; P < 0.01) decreased in superovulated animals. In addition, the expression of FSHR and CYP19A1 increased while the expression of STAR in GCs decreased (P < 0.05). Finally, in superovulated buffaloes a decreased expression of PGR, ER1, VEGF and its receptor FLK1 in the oviduct was observed. The results suggest that the exogenous FSH treatment impairs steroidogenesis, affecting both the oviduct and the ovarian function, accounting for the failure of ovum capture in superovulated buffaloes.

Abstract
The aim of this research was to estimate the variability between buffalo as oocyte donors. In Experiment 1, reproductive variables were retrospectively analyzed in buffalo (n=40) that underwent repeated ovum pick up (OPU), over 16 puncture sessions (PS). The follicular recruitment among individuals and the relationship between follicular population and oocyte production were evaluated. In Experiment 2, eight buffalo underwent OPU for 28 PS and the oocytes were processed separately to correlate follicular and oocyte population at the first PS to blastocyst (BL) production. In Experiment 1, the average number of total follicles (TFL), small follicles (SFL), cumulus-oocyte complexes (COC) and Grade A+B COC recorded in each 4-PS period had great repeatability (r=0.52, 0.54, 0.60 and 0.57, respectively). The average number of Grade A+B COC recovered during the subsequent 15 PS was positively correlated with the first PS number of TFL (r=0.60; P<0.001), SFL (r=0.68; P<0.001), COC (r=0.48; P<0.01) and Grade A+B COC (r=0.40; P<0.05). In Experiment 2, a large variability among animals was observed in blastocyst yields. When animals were grouped according to the BL yield, the greatest BL yield group had a greater (P<0.05) number of TFL (8.3 ± 0.9 compared with 5.6 ± 0.7) and SFL (7.3 ± 0.3 compared with 3.8 ± 0.7) at the first PS than the lesser BL yield group. The average number of BL produced over the subsequent sessions was correlated with the number of TFL (r=0.80; P<0.05) and COC (r=0.76; P<0.05) observed at the first PS. These results demonstrated a donor influence on the oocyte and BL production, suggesting a preliminary screening to select the donors with greater potential.

Abstract
The objective of this study was to evaluate the effect of bovine somatotropin (bST) on ovarian follicular population in buffalo heifers and its influence on oocyte quality, recovery rates and in vitro embryo production. We tested the hypothesis that bST treatment in buffalo females submitted to an ovum pick-up (OPU) program would improve the number of follicles recruited, oocyte quality and in vitro embryo production. A total of 10 heifers were assigned into two treatment groups: group bST (n=5; receiving 500 mg of bST in regular intervals) and control group (n=5; without additional treatment). Both groups were subjected to OPU sessions twice a week (every 3 or 4 days), for a total of 10 sessions per female, although due to procedural problems, only the first five OPU sessions produced embryos. The number of follicles and the diameters were recorded at all OPU sessions. The harvested oocytes were counted and classified according to their quality as either A, B, C, D or E, with A and B considered good quality. Cleavage and blastocyst production rates were evaluated 2 and 7 days after in vitro fertilization, respectively. The bST treatment increased the total number of antral follicles (>3mm in diameter; 12.2 compared with 8.7; p<0.05) and of small antral follicles (<5mm; 9.1 compared with 6.5; p<0.05) per OPU session. The bST also tended to increase the number of oocytes recovered per session (5.2 compared with 4.1; p=0.07), and enhanced the percentage of good quality oocytes (48.8% compared with 40.6%; p=0.07). bST showed no effect on cleavage and blastocyst production rates (p>0.05). The significant effects of performing repeated OPU sessions were decreasing the follicular population (p<0.001) as well as the number of follicles aspirated (p<0.001), and oocytes recovered (p<0.02). In conclusion, bST treatment improves the follicular population, demonstrating its possible application in buffalo donors submitted to OPU programs.

Abstract
The aim of this study was to evaluate the efficiency of the solid surface vitrification (SSV) and the cryoloop vitrification (CLV) methods to cryopreserve in vitro matured buffalo oocytes. Another objective of the work was to investigate whether the presence of cumulus cells affects the efficiency of oocyte vitrification in this species. In the SSV method, oocytes were vitrified in a solution of 35% ethylene glycol, 5% polyvinyl-pyrrolidone and 0.4% trehalose and they were warmed in a 0.3M trehalose solution. In the CLV method, oocytes were vitrified in 16.5% ethylene glycol and 16.5% dimethyl sulfoxide and warmed in decreasing concentrations of sucrose. The oocytes that survived vitrification were fertilized and cultured in vitro up to the blastocyst stage. Although high survival rates were recorded in all groups, when the oocytes were vitrified by the CLV method in the absence of cumulus cells, the survival rate was significantly (P<0.05) lower. However, the CLV gave a significantly higher cleavage rate compared to the SSV with the denuded oocytes (45% versus 26%, respectively; P<0.05), whereas no differences were found between methods with the cumulus-enclosed oocytes (14% versus 15%, respectively). Blastocysts were produced for the first time from in vitro matured oocytes that were vitrified-warmed in buffalo. Nevertheless, vitrification significantly decreased blastocyst yield, regardless of both the method employed and the presence or absence of cumulus cells.

Abstract
The purpose of this study was to evaluate whether enriching the oocyte in vitro maturation medium with cystine, in the presence of cysteamine, would improve the in vitro embryo production efficiency in buffalo by further increasing the GSH reservoir created by the oocyte during maturation. Cumulus-oocytes complexes were matured in vitro in TCM 199 + 10% FCS, 0.5 microg/ml FSH, 5 microg/ml LH and 1 microg/ml 17beta-estradiol in the absence or presence of cysteamine (50 microM), with or without 0.3mM cystine. In Experiment 1, glutathione content was measured by high-performance liquid chromatography and fluorimetric analysis in representative samples of oocytes matured in the four different experimental conditions. In Experiment 2, oocytes were fixed and stained to assess nuclear maturation and normal pronuclear development following IVM and IVF respectively. In Experiment 3, mature oocytes were in vitro fertilized and cultured to assess development to blastocysts. In all supplemented groups the intracytoplasmic GSH concentration was significantly higher than the control, with the highest GSH levels in oocytes matured in the presence of both thiol compounds (3.6, 4.7, 5.4 and 6.9 picomol/oocyte in the control, cysteamine, cystine and cystine+cysteamine groups, respectively; P < 0.05). Cystine supplementation of IVM medium, both in the presence or absence of cysteamine, significantly increased the proportion of oocytes showing two normal synchronous pronuclei following fertilization. In all supplemented groups, cleavage rate was significantly improved compared to the control (55, 66.1, 73.5 and 78.4% in the control, cysteamine, cystine and cystine+cysteamine groups, respectively; P < 0.05). Similarly, blastocyst yield was also increased in the three enriched groups compared to the control (17.1, 23.8, 29.3, 30.9% in the control, cysteamine, cystine and cystine+cysteamine groups, respectively; P < 0.05). Overall, the addition of cystine to a cysteamine-enriched medium resulted in a significant increase of cleavage rate and transferable embryo yield compared to the medium supplemented with only cysteamine.
