Developmental biology: An arresting activity
Nicholas S. Duesbery & George F. Vande Woude
Abstract
Vertebrate eggs pause at a crucial stage in their development, starting again only after being fertilized by sperm. Another component of the activity that ensures this arrest has been identified.
The process of vertebrate egg development consists of oocyte growth coupled with specific pauses at various stages of maturation. The final pause is known as the metaphase II arrest, from which eggs are released only after being fertilized by sperm.
