Human embryos commonly form abnormal nuclei during development: a mechanism of DNA damage, embryonic aneuploidy, and developmental arrest. Homo sapiens

Nuclear abnormalities are commonly found in human IVF embryos and are associated with DNA damage, aneuploidy, and decreased developmental potential. Overall design: Immunohistochemical, microscopic, and cytogenetic analysis of human IVF embryos at different developmental stages and morphologic grades.
