The objective of this study was to compare bovine and ovine oocytes in terms of (1) developmental rates following maturation, fertilization, and culture in vitro, (2) the quality of blastocysts produced in vitro, assessed in terms of their ability to undergo cryopreservation, and (3) the ultrastructural morphology of these blastocysts. In vitro blastocysts were produced following oocyte maturation/fertilization and culture of presumptive zygotes in synthetic oviduct fluid. In vivo blastocysts… Expand
Differences in the incidence of apoptosis between in vivo and in vitro produced blastocysts of farm animal species: a comparative study.
TLDR
Although in morphologically high quality blastocysts of several farm animal species a significant difference exists in the percentages of apoptotic cells between in vivo and in vitro produced embryos, the incidence of apoptosis at the blastocyst stage is at such a low level that it cannot reflect the substantial differences in embryo viability. Expand
Temporal sensitivity of bovine embryos to culture environment after fertilization and the implications for blastocyst quality.
TLDR
Examination of the temporal sensitivity of bovine embryos to culture environment after fertilization found which period, if any, is most critical in determining blastocyst quality, as reflected in the relative abundance of transcripts for the Bax gene. Expand
Gene expression in bovine embryos derived from oocytes with different developmental competence collected at the defined follicular developmental stage.
TLDR
It is concluded that the relative abundance of Cx 43 can be used as a marker of developmental potential for embryos derived from oocytes with different developmental competence because the level of CX 43 transcript was greater in embryosderived from oocyte with greater developmental competence compared with those derived from Oocytes with lesser developmental competence. Expand
Culture of early stage ovine embryos to blastocyst enhances survival rate after cryopreservation.
TLDR
It is indicated that, despite the deleterious effects of culture per se, the culture of early in vivo produced ovine embryos to the blastocyst stage prior to be frozen improves their survival after thawing. Expand

RNA-Seq analysis uncovers transcriptomic variations between morphologically similar in vivo- and in vitro-derived bovine blastocysts
TLDR
The results support that IVF may influence at the transcriptomic level and that morphology is limited in full characterization of bovine preimplantation embryos. Expand
The impact of oocyte maturation media on early bovine embryonic development
TLDR
The results show that the oocyte culture media have strong impact on the quality of embryos produced in vitro and emphasize the need for more in depth evaluation of oocyte maturation protocols. Expand
Ultrastructural Study of in Vitro Produced Bovine Embryos during Early and Late Development
TLDR
In vitro produced bovine embryos of late development had greater degrees of mitochondrial alterations than those of early development, which could indicate that mitochondrial alterations play a primordial deleterious role in the delayed development, normally observed in in vitro produced embryos. Expand
In vitro development and post-thaw survival of blastocysts derived from delipidated zygotes from domestic cats.
TLDR
Removal of the cytoplasmic lipid content in feline zygotes did not impair their in vitro developmental competence (up to the blastocyst stage), and reduction of cytopLasmic lipids by aspiration had no apparent effects on the survival of in vitro-derived blastocysts after cryopreservation. Expand
Maturation, fertilisation and culture of bovine oocytes and embryos in an individually identifiable manner: a tool for studying oocyte developmental competence.
TLDR
It is demonstrated that it is possible to culture bovine oocytes to the blastocyst stage in an individually identifiable manner in all three culture systems with comparable success rates, which permits the localisation and identification of individual embryos throughout preimplantation development in vitro while retaining the developmental benefits of group culture.

Ultrastructural Morphometry of Bovine Blastocysts Produced In Vivo or In Vitro1
TLDR
Blastocysts produced in vitro possessed deviations in volume densities of organelles associated with cellular metabolism as well as deviations associated with altered embryonic differentiation, however, the specific nature of these deviations varied with the type of culture conditions used for in vitro embryo production. Expand
Culture of in vitro produced bovine zygotes in vitro vs in vivo: implications for early embryo development and quality.
TLDR
It is demonstrated that while bovine zygotes cultured in vitro are capable of rates of development similar to those of their in vivo cultured counterparts, there are significant differences in embryo cryosurvival. Expand
Consequences of bovine oocyte maturation, fertilization or early embryo development in vitro versus in vivo: Implications for blastocyst yield and blastocyst quality
TLDR
The results indicate that the intrinsic quality of the oocyte is the main factor affecting blastocyst yields, while the conditions of embryo culture have a crucial role in determining Blastocyst quality. Expand
Effect of culture system on the yield and quality of bovine blastocysts as assessed by survival after vitrification.
TLDR
In conclusion, a bovine in vitro culture system can affect blastocyst yield and quality and crytolerance is a useful indicator ofblastocyst quality. Expand
Ultrastructure of bovine blastocysts following cryopreservation: Effect of method of blastocyst production
TLDR
The findings of the present study indicate that in vivo derived blastocysts possess certain structural characteristics that confer a greater tolerance on them to exposure to cryoprotectant and cryopreservation. Expand
Morphological and physiological differences between in vivo- and in vitro-produced preimplantation embryos from livestock species
TLDR
This manuscript is a review of the literature concerning studies that compared in vitro-manipulated to in vivo-produced preimplantation embryos from the farm species and apologies in advance for studies which were inadvertently omitted. Expand
Compaction rate of in vitro fertilized bovine embryos related to the interval from insemination to first cleavage.
TLDR
It is indicated that developmentally capable bovine embryos reach the 2- cell stage at 36 hours post insemination, and that they become compacted at the 32-cell stage, which usually occurs between 126 and 138 hours post Insemination. Expand
Intercellular communication in in vivo- and in vitro-produced bovine embryos.
TLDR
The late and reduced expression of intercellular communicative devices in in vitro-produced embryos may be one of the factors explaining their developmental low efficiency. Expand

TLDR
Pregnancies resulting from in-vitro-derived embryos were characterized by the following features: sex ratio skewed in favour of males; increased spontaneous abortion rate throughout gestation; reduced intensity of labour in recipients; and increases in birth weights, dystocias, calf mortality, and fetal abnormalities.

Timing of the first cleavage post‐insemination affects cryosurvival of in vitro–produced bovine blastocysts
TLDR
Results indicate that the day of blastocyst appearance, developmental stage, and timing of the first cleavage post‐insemination can influence the cryosurvival of bovine blastocysts following vitrification. Expand
