## differentiation

[dĭf′ə-rĕn′shē-ā′shən]

- In calculus, the process of computing the derivative of a function. Compare integration.
- 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.
