The inheritance of an organism tells cells to differentiate during embryonic development.
during embryonic development
The major issue involving the harvesting of embryonic stem cells is that the embryonic stem cells can cause the destruction of an embryo.
Bipolar neurons in the ciliary ganglion only exist during embryonic development and in vitro. Adult in vivo choroid and ciliary neurons in the ciliary ganglion are all unipolar.
The term "fetus" refers to the stage of development after the embryo. The two-cell stage of development comes well before the embryonic stage. There is no point at which a fetus, by definition, has two cells.

during embryonic development
Embryonic phase is the period of human development. This is when the cells change.
the blastula is an early stage of embryonic development in animals. its a hollow sphere of cells surrounding an inner fluid-filled cavity called the blastocoele formed during an early stage of embryonic development in animals
Cells change (differentiate) substantially in morphology during embryonic and fetal development.
a group of specialized cells forms tissue, a group of tissue forms an organ
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
During embryonic development cells specialize to form tissues. Mitotic cell division is very important during body growth. After this time muscle tissue becomes amniotic.
During embryonic development, part of the mesoderm breaks away and starts to form the heart. The embryonic stem cells differentiate primarily into myocardial cells, with the endoderm forming the endocardium and valves and the ectoderm forming the pericardium and pericardial sac. The exact steps aren't well known - embryology has more questions than answers for human development at this time.
Dead Embryonic Cells was created in 1991.
