Centriolar satellites are nonmembranous, electron-dense and spherical cytoplasmic granules of about 70-100 nm in diameter, occurring around centrosomes in most vertebrate cell types. They contain a number of centrosomal proteins. Centriolar satellites have the ability to move along microtubules, toward their minus ends, i.e. toward centrosomes. Their number increase during interphase and decrease during mitosis.
