Epigenome orchestrates embryonic development

Studying zebrafish embryos, researchers at Washington University School of Medicine in St. Louis have shown that the epigenome plays a significant part in guiding development in the first 24 hours after fertilization. The research may deepen understanding of congenital defects and miscarriage.
