Differentiation

Definition

noun

(developmental biology) The normal process by which a less specialized cell develops or matures to become more distinct in form and function.

(medicine) The determination of which among the diseases with similar symptoms is the one that the patient is suffering, especially through a systematic method.


Supplement

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

Compare: dedifferentiation.

An Overview of Embryonic Stem Cells

... of murine ES cell lines in 1981 contributed to a simple model system for studying the basic processes of early embryonic development and cellular differentiation, marking a major breakthrough for developmental biology in the history. And later scientists were wondering that if ES cells could be ...

Stem Cells and Cell division?

Cell division demands lot of resources in the form of energy. Therefore, it is easy to have dedicated cells for division and differentiation. Therefore, normal cells can continue doing their tissue function whereas adult stem cells perform their function i.e. dividing and replacing damaged ...

Possible reasons could be related to hydrostatic pressure, changes in gene expression in stem cells resulting in differentiation, osteoclast degradation enabling interstitial growth, or gene signaling from the articular cartilage/synovial joint. When the articular ...
