The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells
Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged single culture on the rate of diploid cells in human embryos with aneuploidies. MaterialsAndMethods In this cohort study, we used fluorescence in ...
متن کاملEfficient reproduction of cynomolgus monkey using pronuclear embryo transfer technique.
One of the technical bottlenecks in producing nonhuman primate models is that current assisted reproductive techniques, such as in vitro culture and frozen conservation of multicell-stage embryos, often result in poor embryo quality and subsequently lead to low birth rates. We investigated whether pronuclear embryo transfer can be used as an effective means for improving pregnancy and live birt...
متن کاملFate mapping the mouse embryo.
The use of clonal analysis to obtain a fate map of the epiblast of the mouse embryo and to investigate cell distribution during gastrulation and early neurulation is described in a personal reminiscence. A revised fate map of the epiblast at 6.5 days gestation is provided, and the development of 3-dimensional, quantitative image analysis techniques outlined.
متن کاملGenome-wide uniparental disomy screen in human discarded morphologically abnormal embryos
Uniparental disomy (UPD) has been shown to be rare in human normal blastocysts, but its frequency in discarded morphologically abnormal embryos and its relevance to embryonic self-correction of aneuploid remains unknown. The aim of this study was to detect UPD in discarded morphologically abnormal embryos. Both discarded morphologically abnormal embryos, including zero-pronuclear zygotes (0PN),...
متن کاملThe fate of the mosaic embryo: chromosomal constitution and development of Day 4, 5 and 8 human embryos.
BACKGROUND Post-zygotic chromosome segregation errors are very common in human embryos after in vitro fertilization, resulting in mosaic embryos. However, the significance of mosaicism for the developmental potential of early embryos is unknown. We assessed chromosomal constitution and development of embryos from compaction to the peri-implantation stage. METHODS From 112 cryopreserved Day 4 ...
