In developmental biology, cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Different tissues have different kinds of cells.
Characteristics of cell differentiation: 1  Cell differentiation is a stable phenomenon. 2  Differentiation is induced by specific stimuli. 3  But once differentiated or established, these cells are stimulus independent. 4  Differentiation is accomplished by morphological difference of that fated or determined cell.
