Cellular differentiation

Definition

noun

The normal process by which a less specialized cell develops or matures to possess a more distinct form and function.


Supplement

For example, a single-celled zygote develops into a multicellular embryo that further develops into a more complex multisystem of distinct cell types of a fetus. The cell size, shape, polarity, metabolism and responsiveness to signals change dramatically such that a less specialized cell becomes more specialized and acquires a more specific role.


Variant: cell differentiation.

Compare: dedifferentiation.
