Preimplantation human embryos are characterized by various degrees of cytoplasmic fragmentation, and a high incidence of developmental arrest before the blastocyst stage. This review examines the current morphological and biochemical evidence that apoptosis plays a role in early human development and embryonic loss. Embryos examined 24 h or more after arrest often show characteristic features of apoptosis including cytoplasmic, nuclear and DNA fragmentation. In contrast, embryos of good… Expand
Apoptosis in mammalian preimplantation embryos: Regulation by survival factors
  • D. Brison
  • Biology, Medicine
  • Human fertility
  • 2000
TLDR
The regulation of apoptosis in the preimplantation embryo is likely to be of critical importance for both embryo viability and for later development, since the cells of the inner cell mass give rise to the fetus and carry the germ line. Expand
From cell death to embryo arrest: mathematical models of human preimplantation embryo development.
TLDR
Research on improving in vitro fertilization success rates should move from its current concentration on optimizing culture media to focus more on the generation of a healthy zygote and on understanding the mechanisms that cause chromosomal and other abnormalities during early cleavage stages.

Genetic regulation of preimplantation embryo survival.
  • R. Lévy
  • Biology, Medicine
  • International review of cytology
  • 2001
TLDR
This review focuses on the recent advances concerning genetic regulation of preimplantation embryo survival, and the predominant role of the Ped(preim implantation embryo development) gene, which regulates fast or slow cleavage of preIMplantation mouse embryos, and its implication on embryo survival.

Chronology of Apoptosis in Bovine Embryos Produced In Vivo and In Vitro
TLDR
This study is the first to investigate the independent chronological occurrence of apoptotic changes in nuclear morphology and DNA degradation (detected by the TUNEL reaction) and incidences of nuclei displaying these features at various preimplantation stages of bovine embryos produced both in vivo and in vitro. Expand
Caspase activity in preimplantation human embryos is not associated with apoptosis.
TLDR
Caspase activity was detected only after fertilization, and was rare in blastomeres but frequent in fragments, which suggest that caspases in preimplantation human embryos are involved in developmental processes unrelated to cell death. Expand
Expression of Smac/DIABLO in mouse preimplantation embryos and its correlation to apoptosis and fragmentation.
TLDR
Immunohistochemistry studies showed that the Smac/DIABLO protein localized in mitochondria and was released into the cytosol in both fragmented embryos and embryos in which apoptosis was induced by staurosporine, indicating that the SMAC/DiaBLO is involved in the fragmentation and apoptosis of preimplantation embryos. Expand
Apoptosis and In Vitro Development of Preimplantation Porcine Embryos Derived In Vitro or by Nuclear Transfer1
TLDR
The development of porcine nuclear transfer embryos reconstructed by using fetal fibroblasts as compared to embryos produced by in vitro fertilization was investigated to identify specific apoptotic pathways and intervene in these pathways to improve development. Expand
Survivin acts as an antiapoptotic factor during the development of mouse preimplantation embryos.
TLDR
Results indicate that survivin is an essential antiapoptotic gene expressed in preimplantation embryos and could protect the embryos from apoptosis by inhibiting an apoptotic pathway involving caspases. Expand
Influence of apoptosis in bovine embryo's development.
TLDR
It was demonstrated that bovine embryonic arrest at different stages of development is correlated with the apoptotic mechanisms. Expand
Chronological appearance of apoptosis in bovine embryos reconstructed by somatic cell nuclear transfer from quiescent granulosa cells.
TLDR
Investigation of the chronological onset of both apoptotic changes in nuclear morphology and DNA degradation in bovine two-cell- to blastocyst-stage embryos finds that reconstructed embryos displayed elevated ratios of embryos containing apoptotic nuclei at pre-compaction stages and higher indices of apoptoticuclei in morula and Blastocyst stages when compared with in vitro-produced embryos.

Cell death in the mammalian blastocyst.
  • K. Hardy
  • Biology, Medicine
  • Molecular human reproduction
  • 1997
TLDR
There is evidence that levels of cell death are regulated by 'survival' factors produced both by the embryo itself and by the maternal reproductive tract, and that these factors are implicated in blastocyst cell death and the reasons for apoptosis in the early embryo. Expand
Ultrastructural evaluation of 8–16 cell human embryos cultured in vitro
TLDR
The organization of two 8-cell embryos was apparently normal while the other embryos showed varying aspects of abnormal development, and the importance of ultrastructural evaluation of embryos in an in vitro programme is revealed. Expand
Relationship between morphology and chromosomal constitution in human preimplantation embryo
TLDR
These results, pooled with data drawn from previous reports, demonstrated the prognostic value of the embryo grading system as a means for eliminating chromosomally abnormal embryos and suggested that some aspects of the IVF process might be responsible for the occurrence of these abnormalities. Expand
Development of Human Blastocysts In Vitro
TLDR
Until recently, relatively little was known about human preimplantation development, mainly due to the inaccessibility of the human embryo after normal conception, but in vitro fertilization for the treatment of infertility has provided clues as to possible reasons for the low success rate of human IVF. Expand
The human blastocyst: cell number, death and allocation during late preimplantation development in vitro.
TLDR
The development of 181 surplus human embryos, including both normally and abnormally fertilized, was observed from day 2 to day 5, 6 or 7 in vitro, and there was widespread cell death in both the TE and ICM as evidenced by fragmenting nuclei, which increased substantially by day 7. Expand
Hyperglycemia induces apoptosis in pre-implantation embryos through cell death effector pathways
TLDR
It is demonstrated that expression of Bax, a Bcl-2-like protein, is increased at the blastocyst stage in the presence of high concentrations of glucose, and that these changes correlate morphologically with increased DNA fragmentation. Expand
Effects of glutamine and taurine on preimplantation development and cleavage of mouse embryos in vitro.
TLDR
Study of the development of embryos from F1 hybrid female mice in CZB and KSOM, from the zygote to the blastocyst stage, in the presence and absence of 1 mM glutamine and/or 5 mM taurine found that glutamine had no effect on the proportion of embryos developing to the blasting stage, but it significantly reduced cell number at the blastocytes stage.

Binucleate blastomeres in preimplantation human embryos in vitro: failure of cytokinesis during early cleavage
TLDR
Estimates of the volume of binucleate blastomeres based on measurement of their diameters and comparison with mononucleateblastomeres at various cleavage stages indicated that these blastomere arise from a failure of cytokinesis between the second and fourth cleavage divisions. Expand
Differentiation of the Blastocyst of the rhesus monkey.
TLDR
The observation that enlarged torn zonae were found in association with one blastocyst and unaccompanied by blastocysts, including a case in which the animal subsequently prove to be pregnant, suggests that hatching is a normal feature of zonal escape in this species. Expand
