The process "provides an embryo-wide census of aneuploidy across early development and quantifies parameters of chromosomal mosaicism that have proven elusive to biopsy-based studies," the paper ...

Chromosome loss was also seen in 16% of embryos and although this was frequently associated with abnormal spindle configurations, some otherwise normal spindles were also linked to chromosome loss.

The presence of an abnormal number of chromosomes in embryos is a major cause of impaired embryo development. But mosaic embryos, comprising both genetically normal and abnormal cells, can result ...

One such technology, preimplantation genetic diagnosis for aneuploidy (PGD-A), the subject of ongoing controversy, is nevertheless being increasingly deployed to select for euploid embryos—those ...

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo (called a cleavage stage embryo) with an incorrect ...

Aneuploidy (the presence of an abnormal number of chromosomes) in embryos is a major cause of impaired embryo development, leading to conditions such as Down syndrome, as well as to pregnancy loss.
