HOW DOES A CELL BECOME SPECIALIZED?
During transcription, the DNA becomes prone to mutations and the process of cell specialization makes it less susceptible to them, hence preventing further damage in the gene
multiple stages of development. During cell specialization, the cell size and shape changes dramatically, as does its ability to respond to signaling molecules.
One of the most overlooked significance of cell specialization is its importance in the production of cells that can produce signals that influence the activities of their neighboring cells. As a result, these cells collectively react toward a specific stimulus.
these stem cells can remain “un-specialized” until they need to.

REPLACEMENT OF OLD AND WORN-OUT CELLS

IMPORTANCE IN CELL-TO -CELL COMMUNICATION
PRESERVE THE GENETIC MATERIAL
The division of these stem cells into specialized cells is often triggered by certain environmental conditions. For instance, these new cells from the stem cells will then be used to replace any old or worn-out cells, hence maintaining their integrity as tissues or organs.
