3. The process by which cells or parts of an organism change during development to serve a specific function. The cells of an animal in its early embryonic phase, for example, are identical at first but develop by differentiation into specific tissues, such as bone, heart muscle, and skin. The factors determining the differentiation of any particular cell are not well understood, but in deuterostomes (vertebrates and other complex animals) they include the location of the cell relative to other cells.

Etymology

Origin of differentiation

First recorded in 1800–10; differentiat(e) + -ion

Explanation

Differentiation is how someone or something is set apart from others. If you make a differentiation between one brand of toothpaste and another, you point out how they're distinct. You can see the word different in differentiation. The -tion ending tips you off that differentiation is the noun form of different: differentiation refers to the differences themselves. Suppose two very similar movies come out at the same time. The studios will work to achieve differentiation in the films' trailers, with one highlighting the chemistry between the romantic leads and the other showing moments of slap-stick comedy.
