However, since the development of the embryo does not cease, more developed larvae will hatch out.
Biologists who study the development of the embryo were the first to describe programmed cell death.
Cytoplasmic localization is evident in the earliest stages of development of the embryo.
Gene-targeting technology can knock out single genes to study development of the embryo, aging and normal physiology.
Instead of civilization being artificial, it is a part of nature; all of a piece with the development of the embryo or the unfolding of a flower".
Developmental biologists would snip out pieces of embryos or graft parts together and watch how the development of the embryo was altered.
During the development of the embryo, the epicardium turns into the many types of cells seen in the heart and surrounding blood vessels.
He then hired GeesePeace to train volunteers in egg addling, a method of arresting development of the embryo by coating the eggs in corn oil.
Scientists suspect that excess embroyologic tissue plays a role, and that both genetic factors and environmental stresses early in development of the embryo could be at work.
The heart is not an exception and its highest regeneration capacity is found during development of the embryo, which resides in a relatively hypoxic environment.
Changes in chromosome number occur during sperm or egg formation or in the early development of the embryo.
