If you mean change in genes, this is done by a process called recombination, whereby chromosomes switch legs at random points to help add variety to our genes.
But I suspect you mean how identical cells in some kind of embryo form different types of cells. At a point in the growth of the embryo, the cells start reacting to external factors, mostly chemicals produced by the cells around it. Although all cells contain all genes, the chemicals act as a switch to turn genes on or off. Cells on the outside of the embryo get different signals than those on the inner layers. Cells also tend to express genes that are expressed in the cells surrounding it, because of the chemical signals given off by those cells. As cells start to change what genes they express and become more specialized they give off more and more specific chemicals, making the differentiation that much more complex. This is a very complicated process, but I hope that this very brief overview has helped. For more information, research developmental Biology, differentiation, and specialization.
I have a BS in molecular and cell biology.

It isn't a better knowledge of cell division, but rather, a better knowledge of cell differentiation that allows us the possibility of one day inducing limb or organ regeneration. We know a lot about mitosis, but not nearly enough about the signals that induce differentiation.
development
Granulation tissue is derived from the endothelial lining of blood vessels.
Neurons lose their centrioles during differentiation, and they become incapable of undergoing cell division.
A growth factor is a signaling molecule which is secreted by the cell and sensed by itself and other cells. They are capable of stimulating cellular growth, proliferation, and cellular differentiation. Usually it is a protein or a steroid hormone. Growth factors are important for regulating a variety of cellular processes.
Cell division and differentiation
yess
Differentiation is a very complicated regulated process that occurs during development of the cell. The process is triggered by specific growth factors that direct the cell towards a particular lineage of cells, during which parts (genes) of DNA unnecessary for the activity of that particular lineage are supercoiled and kept as such until the time for division.

MITOSIS is the process by which cell division occurs in organisms for the purposes of growth and differentiation of tissues.
to differentiation the cells
The purpose of cell differentiation is to allow a regular cell to develop into a specific cell.
