Abstract
We aimed to evaluate if protein source (PS) alterations during IVM affect embryo sex/development and gene expression profile in cumulus cells (CCs). Bovine oocytes were matured and cultured in the presence of FBS or BSA. Then, the PS effect during IVM on gene expression (GPC4, VCAN, GHR, PTGS2, and ALCAM) was determined. CC biopsy was removed before and after IVM treatments. After fertilization and cultured, CCs were grouped according to their fate into CCs from immature COCs, CCs from COCs that did or did not result in embryos (according to PS). Results showed that when the culture was performed in FBS presence, blastocyst rate was higher (p < 0.05) than BSA. However, when embryos were cultured with BSA, no effect (p > 0.05) of PS during IVM was observed. PS used during IVM did not affect embryos sex (p > 0.05) but changed VCAN, GHR, PTGS2, and ALCAM genes expression. No differences (p > 0.05) were observed between immature and mature CCs groups in gene expression, regardless of their fate. Only the GHR gene was related to embryo production but just with FBS on IVM. In conclusion, PS can affect embryo development when using the serum on IVM and IVC, influences CCs gene expression, and has to be considered when studying oocyte quality markers.

Abstract
The present study aimed to identify biomarkers to assess the quality of in vitro produced (IVP) bovine embryos in the culture media. IVP embryos on Day (D) 5 of development were transferred to individual drops, where they were maintained for the last 48 h of culture. Thereafter, the medium was collected and the embryos were transferred to the recipients. After pregnancy diagnosis, the media were grouped into the pregnant and nonpregnant groups. The metabolic profiles of the media were analyzed via electrospray ionization mass spectrometry, and the concentrations of pyruvate, lactate, and glutamate were assessed using fluorimetry. The spectrometric profile revealed that the media from embryos from the pregnant group presented a higher signal intensity compared to that of the nonpregnant group; the ions 156.13 Da [M + H]+, 444.33 Da [M + H]+, and 305.97 Da [M + H]+ were identified as biomarkers. Spent culture medium from expanded blastocysts (Bx) that established pregnancy had a greater concentration of pyruvate (p = 0.0174) and lesser concentration of lactate (p = 0.042) than spent culture medium from Bx that did not establish pregnancy. Moreover, pyruvate in the culture media of Bx can predict pregnancy with 90.9% sensitivity and 75% specificity. In conclusion, we identified markers in the culture media that helped in assessing the most viable IVP embryos with a greater potential to establish pregnancy.

Abstract
This study aimed to evaluate the effect of scriptaid during pre-maturation (PIVM) and/or maturation (IVM) on developmental competence of bovine oocytes. Cumulus-oocyte complexes (COCs) were submitted to PIVM for 6 h in the presence or absence of scriptaid. COCs were distributed into five groups: T1-IVM for 22 h, T2-PIVM for 6 h and IVM for 22 h, T3-PIVM with scriptaid for 6 h and IVM for 22 h, T4-PIVM for 6 h and IVM with scriptaid for 22 h, and T5-PIVM with scriptaid for 6 h and IVM with scriptaid for 22 h. Nuclear maturation, gene expression, cumulus cells (CCs) expansion, and embryo development and quality were evaluated. At the end of maturation, all groups presented the majority of oocytes in MII (P>0.05). Only HAT1 gene was differentially expressed (P<0.01) in oocytes with different treatments. Regarding embryo development at D7, T4 (23%) and T5 (18%) had lower blastocyst rate (P<0.05) than the other treatments (T1 = 35%, T2 = 37% and T3 = 32%). No effect was observed when scriptaid in PIVM was used in less competent oocytes (P>0.05). In conclusion, presence of scriptaid in PIVM and/or IVM did not improve developmental competence or embryo quality.

Abstract
In this study, we investigated the effects of melatonin supplementation in the culture medium and blastocoel fluid removal (BFR) before vitrification on the quality and viability of in vitro-derived bovine embryos. After fertilization, presumptive zygotes were assigned to one of the following treatments: control, in vitro standard culture (IVC) medium; IVC + M10-9, IVC medium supplemented 10-9 M melatonin; or IVC + M10-9 BFR, IVC medium supplemented with 10-9 M melatonin plus BFR on day 7 (D7) of culture. D7 blastocysts were vitrified by the Cryotop method and, after 5 mo of storage, were warmed and incubated for an additional 72 h. The re-expansion rate was evaluated after 2 and 24 h, and the hatching rate was evaluated after 24, 48, and 72 h. At 72 h, the total number of cells (TNC); number of apoptotic cells (NAC); and expression of genes related to oxidative stress (HSPA5), cell metabolism (SLC2A3), cell repair (MSH6), placentation (KRT8 and PLAC8), and implantation (FOSL1) were assessed in the blastocysts. Less than 30% of the control blastocysts re-expanded until 2 h, whereas more than 85% of the IVC + M10-9 and IVC + M10-9 BFR blastocysts re-expanded (P < 0.05). The hatching rate of IVC + M10-9 BFR blastocysts increased at all time points (P < 0.05), reaching 66.8% at 72 h of incubation. The TNC was similar among treatments (P > 0.05), regardless of vitrification/warming and re-cultivation. The NAC:TNC was smaller for melatonin-treated blastocysts (P < 0.05). BFR increased HSPA5 (P = 0.0118) expression and did not affect SLC2A3, MSH6, KRT8, and FOSL1 expression (P > 0.05). In conclusion, melatonin (10-9 M) supplementation in the culture medium and BFR on D7 of culture increased the hatching rate 24, 48, and 72 h after warming of the vitrified embryos, indicating an improvement in cryotolerance.

Abstract
The aim of this work was to investigate the methylation and hydroxymethylation status of mesenchymal stem cells (MSC) from amniotic fluid (MSC-AF), adipose tissue (MSC-AT) and fibroblasts (FIB-control) and to verify the effect of trichostatin A (TSA) on gene expression and development of cloned bovine embryos produced using these cells. Characterization of MSC from two animals (BOV1 and BOV2) was performed by flow cytometry, immunophenotyping and analysis of cellular differentiation genes expression. The cells were used in the nuclear transfer in the absence or presence of 50 nM TSA for 20 hr in embryo culture. Expression of HDAC1, HDAC3 and KAT2A genes was measured in embryos by qRT-PCR. Methylation results showed difference between animals, with MSC from BOV2 demonstrating lower methylation rate than BOV1. Meanwhile, MSC-AF were less hydroxymethylated for both animals. MSC-AF from BOV2 produced 44.92 ± 8.88% of blastocysts when embryos were exposed to TSA and similar to embryo rate of MSC-AT also treated with TSA (37.96 ± 15.80%). However, when methylation was lower in FIB compared to MSC, as found in BOV1, the use of TSA was not sufficient to increase embryo production. MSC-AF embryos expressed less HDAC3 when treated with TSA, and expression of KAT2A was higher in embryos produced with all MSC and treated with TSA than embryos produced with FIB. The use of MSC less methylated and more hydroxymethylated in combination with embryo incubation with TSA can induce lower expression of HDAC3 and higher expression of KAT2A in the embryos and consequently improve bovine embryo production.

Abstract
The present study analyzed the changes in gene expression induced by the Cryotop vitrification technique in bovine blastocyst-stage embryos, using Agilent EmbryoGENE microarray slides. Bovine in vitro-produced embryos were vitrified and compared with nonvitrified (control) embryos. After vitrification, embryos were warmed and cultured for an additional 4 hours. Survived embryos were used for microarray analysis and quantitative polymerase chain reaction (qPCR) quantification. Survival rates were higher (P < 0.05) in the control embryos (100%) than in the vitrified embryos (87%). Global gene expression analysis revealed that only 43 out of 21,139 genes exhibited significantly altered expression in the vitrified embryos compared to the control embryos, with a very limited fold change (P < 0.05). A total of 10 genes were assessed by qPCR. Only the FOS-like antigen 1 (FOSL1) gene presented differential expression (P < 0.05) according to both the array and qPCR methods, and it was overexpressed in vitrified embryos. Although, the major consequence of vitrification seems to be the activation of the apoptosis pathway in some cells. Indeed, FOSL1 is part of the activating protein 1 transcription factor complex and is implicated in a variety of cellular processes, including proliferation, differentiation, and apoptosis. Therefore, our results suggest that a limited increase in the rate of apoptosis was the only detectable response of the embryos to vitrification stress.

Abstract
The present work aimed to evaluate the transcription and replication inhibitor, actinomycin D, for oocyte chemical enucleation. Cattle oocytes matured in vitro were treated with actinomycin D according to the following treatments: T1, control; T2=1.0 microg/ml for 16 h; T3=1.0 microg/ml for 14 h; T4=2.5 microg/ml for 14 h; T5=5.0 microg/ml for 14 h. The oocytes were denuded and activated during 24-26 h of maturation. Oocytes were fixed to determine the maturation status and for chromosome morphology evaluation. Furthermore, oocytes treated with actinomycin D were used for somatic cell nuclear transfer (SCNT). Parthenogenetic and SCNT embryos were fixed to evaluate the percentage of apoptotic nuclei by the TUNEL assay. The maturation (T1=90.4%; T2=82.3%; T3=79.1%; T4=83.4%; T5=74.7%), cleavage (T1=68.9%; T2=46.0%; T3=49.7%; T4=33.4%; T5=29.3%) and blastocyst rate at D8 (T1=41.1%; T2=1.8%; T3=1.3%; T4=0.9%; T5=0.0%) after actinomycin D treatment were significantly different. There was a significant chromosome uncoiling when treated with greater concentrations (2.5 and 5.0 microg/ml). After SCNT, the cleavage rate (61.3%) was similar to the actinomycin D-treated control group (61.3%) and less than the non-treated control (70.2%), although the blastocyst rate was greater in the SCNT group (11.8%) comparing with the treated control (3.6%) and less than the untreated control (38.0%). Treated parthenogenetic embryos had more apoptotic cells than the parthenogenetic controls (24.2% compared with 4.8%). However, the SCNT group using treated cytoplasts was similar from the SCNT control (9.3 compared with 13.0%). Actinomycin D treatment was efficient in blocking embryonic development. Moreover, it was possible to obtain reconstructed embryos that possess an apoptotic cell index indistinguishable from controls.
