Dictionary » D » Differentiation




(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.


(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.

Trying to prove height increase...need help

... study(fairly intense clamping). 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 ...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

... at most and even then there had been continuous gene flow between different populations of humans. This is certainly not enough time for discrete differentiation to have occurred in any complex trait like intelligence. If we look at Homo sapiens and Neanderthals we see the beginnings of a genetic ...

Re: Multicellular prokaryote

... very definition, they are cells of multicellular descent. Further, the various membranous processes of eukaryotes promotes compartmentalization, differentiation, and importantly: endocystosis which allowed for the 'taking in' of other organisms. Sexual reproduction (especially meiosis) yielded ...

which mechanism triggers the first cell differentiation?

As far as i know , the cell differentiation is close related with two factors: time and location . As you know ,the differentiation began since the fertilization , later contact with neighboring cell can also lead to farther differentiation. ...
