Cellular mechanisms of monozygotic twinning: clues from assisted reproduction
12 Jul 2024
Abstract excerpt
BACKGROUND: Monozygotic (MZ) twins are believed to arise from the fission of a single fertilized embryo at different stages. Monochorionic MZ twins, who share one chorion, originate from the splitting of the inner cell mass (ICM) within a single blastocyst. In the classic model for dichorionic MZ twins, the embryo splits before compaction, developing into two blastocysts. However, there are a growing number of...
