Some cells exit the cell cycle between interphase and division and enter an non-dividing phase called GO. The process that causes cell specialization is called differentiation and occurs when the cell selectively activates or inactivates specific genes. Specialized cells differ in structure and function.
Specialisation occurs during the development of a young cell when a specific gene causes it to build up different features for a particular function. For instance how red blood cells are made to carry oxygen aroudn the body or nerves are specially made for speed to send messages to the brain.
Expression of different genes in different cells makes cells specialized.
Each cell nucleus contains identical DNA, but different mechanisms (for example chemical messengers) decides which genes are expressed in the cell. The genes are the template for m-RNA (messenger-RNA) transcript which then leads to synthesis of proteins. Different proteins in different cells results in different functions of the cell itself.
Cell specialization is a result of cellular evolution. As more and more complex organisms began evolving, there was tremendous evolutionary pressure for cells to attain specialized functions.
Cells begin with a zygote (fertilized egg) and this begins to produce cells that will later on be muscle cells, nerve cells, skin cells and many more by the time the individual is complete.
It goes through a chemical process.
The Cells Contain Different DNA.
The first contact of a T or B cell with its specific antigen is called priming. It causes differentiation into effector T or B cells.
Cell differentiation is a transition of a cell from one cell type to another and it involves a switch from one pattern of gene expression to another.

to differentiation the cells
The purpose of cell differentiation is to allow a regular cell to develop into a specific cell.
Cell Differentation affects an organism and allows it to do different things. If a organism had no Cell Differentation the cells could only do one thing.
The specialization of a Cell occurs in two phases: first Differentiation and second Determination.
The first contact of a T or B cell with its specific antigen is called priming. It causes differentiation into effector T or B cells.
Cell differentiation is a transition of a cell from one cell type to another and it involves a switch from one pattern of gene expression to another.
In cell differentiation: Mapping refers to the different phases, distinguishing between them and analyzing them.
The embryonic stage in which cell migration and differentiation occurs is known as a gastrula.

Stem cells are necessary for cellular differentiation because when they divide, they become specialized cells.
