Embryonic stem cells go through a process calledself-renewal, wherein they undergo multiple cyclesof division while not differentiating into any othertype of cells. This process is dependent on threeprotein networks, which guide both self-renewal and eventual differentiation. But the integration of
these three networks has remained a mystery.

Embryonic growth refers to the overall increase in size and complexity of an embryo as it develops into a mature organism. Cell differentiation is the process by which cells become specialized to perform specific functions, such as becoming muscle cells or nerve cells. Embryonic growth involves both cell proliferation and cell differentiation as the embryo develops.
An example of embryology is the study of how a fertilized egg develops into a fully formed organism, such as a human fetus. This field of biology examines the processes of cell division, differentiation, and growth that occur during embryonic development.
Genetic factors inherited from the parents are most likely to affect cell differentiation in a developing embryo. Mutations or alterations in specific genes can impact the development and specialization of cells, ultimately influencing how different tissues and organs form during embryonic growth.
Ontogeny refers to the development of an individual organism from fertilization to maturity, encompassing growth and differentiation of cells. Phylogeny, on the other hand, refers to the evolutionary history and relationships among groups of organisms over time, tracing their common ancestry and evolutionary changes.
During embryonic development, cells specialize to form different types of tissues and organs in the body through a process called differentiation. This specialization allows cells to take on specific functions and roles, contributing to the overall structure and function of the organism. Differentiation is critical for the growth and development of a healthy, functioning organism.
During embryonic development, DNA provides the genetic instructions that determine the growth and differentiation of cells. These instructions guide the formation of tissues and organs, ultimately shaping the development of the embryo. DNA controls the expression of genes that regulate various processes such as cell division, migration, and specialization, all of which are essential for the development of a fully formed organism.
