centrosomes

The centrosome is an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell as well as a regulator of cell-cycle progression. The centrosome was discovered by Edouard Van Beneden in 1883 and was described and named in 1888 by Theodor Boveri. Fungi and plants use other MTOC structures to organize their microtubules.
