Description
Cytoskeleton
The cytoskeleton (also CSK) is a cellular "scaffolding" or "skeleton" contained within a cell's cytoplasm and is made out of protein. The cytoskeleton is present in all cells; it was once thought to be unique to eukaryotes, but recent research has identified the prokaryotic cytoskeleton. It has structures such as flagella, cilia and lamellipodia and plays important roles in both intracellular transport (the movement of vesicles and organelles, for example) and cellular division. In 1903 Nikolai K Koltsov proposed that the shape of cells was determined by a network of tubules which he termed the cytoskeleton. The concept of a protein mosaic that dynamically coordinated cytoplasmic biochemistry was proposed by Rudolph Peters in 1929 while the term (cytosquelette, in French) was first introduced by French embryologist Paul Wintrebert in 1931.

Le cytosquelette
Le cytosquelette (à réserver au cytoplasme, mais cf. cytomotosquelette) d'une cellule est l'ensemble organisé des polymères biologiques qui lui confèrent l'essentiel de ses propriétés mécaniques. La référence terminologique au « squelette » des vertébrés est cependant trompeuse puisque
-toutes les composantes du cytosquelette sont renouvelées par polymérisation en permanence
-le cytosquelette est à l'origine de la plupart des forces exercées par la cellule pour se déplacer et se nourrir, ce en quoi il s'apparente plutôt à un ensemble de "muscles".
enfin, les propriétés mécaniques du cytosquelette sont très variables suivant les composantes et les situations considérées.
Les cytosquelettes de tous les eucaryotes sont assez similaires (bien que des différences importantes existent entre les cellules animales et végétales), tandis que ceux récemment découverts chez les procaryotes semblent organisés de façon tout à fait différente.
