Examples
- During early embryonic development, epibolies occur as the outer germ layers expand to cover the inner tissues.
- The study of epibolies in amphibian embryos has provided insights into cell migration and tissue formation.
- Researchers observed multiple epibolies taking place simultaneously in the developing zebrafish embryo.
- Epibolies represent a critical phase in gastrulation where morphogenetic movements reshape the embryo.
