Cell Differentiation

The process by which unspecialized cells develop into their mature forms and functions

Embryonic Stem Cells Undifferentiated (unspecialized) Totipotent – can develop into ANY type tissue

Adult Stem Cells Pluripotent or multipotent – can develop into

certain types of tissues.

Cell Differentiation

As division proceeds, cells increase in number, more specialized in structure and function

Nearly all cells have the same DNA, only specific parts are activated

All cells initially have the potential to become any cell

Cell Differentiation- Activity
