Differentiation

Differentiation can involve changes in numerous aspects of cell physiology; size, shape, polarity, metabolic activity, responsiveness to signals, and gene expression profiles can all change during differentiation.

Differentiation and Genetic Cascades
Development of a complex multicellular organism is more than just growth - we certainly do not look like gigantic fertilized eggs.

Differentiation
In time, the cells of the embryo differentiate to form the specialized structures and functions that they will have in the adult. They form neurons, blood cells, skin cells, muscle cells, etc., etc.

differentiation - process whereby cells acquire their mature morphological and biochemical characteristics. Differentiation is often considered a 'final step' of development in which cells take on their mature function.

Lack Differentiation
Normally, cells become differentiated and become capable of specific functions. For example, muscle cells are specialized for contraction, nerve cells (neurons) are specialized for conducting signals, etc.
