Where this comes from

Abstract

Chromosome segregation errors are common in the early stages of human embryonic development. By examining the first mitotic divisions of human embryos using live cell imaging, three recent studies identify spindle architecture and positioning features that could provide insights into why early embryos are predisposed to chromosomal abnormalities.
