The centrosome was discovered by a Belgian scientist named Edouard Van Beneden in 1883 and was given the name by Theodor Boveri in 1888. These organelles are essentially a part of animal cells because in a plant cell, their function is performed by other cell organelles Overabundance of centrosomes and loss of centrosomes have been observed in during development resulting in microcephaly. In the past decade, the field of centriole and centrosome research has made major progress in understanding the basic science behind how centrioles and centrosomes are assembled About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators. The centrosome has several functions. The central one is as the major microtubule organizing center (MTOC) in proliferating animal cells: thus, it helps to organize the microtubules that form the mitotic spindle in dividing cells, and orchestrate a wide variety of cellular processes, including cell motility, signaling, adhesion, coordination of protein trafficking by the microtubule. Within the centrosome are two centrioles with a well-defined structure (centrioles within the centrosome are arranged at a right angle to each other). While the terms centriole and centrosomes do not mean the same thing, it is worth noting that the centrosome is defined by the combination of centrioles surrounded by a protein matrix known as. Centrosome amplification is a hallmark of human tumours. In flies, extra centrosomes cause spindle position defects that result in the expansion of the neural stem cell (NSC) pool and consequently.
