In the past, centrosome maturation has been described as the change in microtubule nucleation potential that occurs as cells pass through specific phases of the cell cycle. It is suggested that the idea of centrosome maturation be expanded to include gain of functions that are not necessarily related to microtubule nucleation.

Centrosomes and Centrosome Equivalents in Other Systems
2022Stem cells are important to sustain tissue growth during development, to repair damaged tissue after injury, and to maintain homeostasis during adulthood. Precisely programmed stem cell renewal and differentiation is critical, as failure in balance can lead to tumorigenesis as a result of over-proliferation or to degeneration as a result of decline in ...

AbstractAlthough the centrosome was first described over 100 years ago, we still know relatively little of the molecular mechanisms responsible for its functions. Recently, members of a novel family of centrosomal proteins have been identified in a wide variety of organisms.

Centrosome Clustering & Chemotherapy
Mini-Reviews in Medicinal Chemistry, 2023Abstract: Centrosome abnormalities are the hallmark of cancer. How it affects tumorigenesis is still a mystery. However, the presence of more than two centrosomes at the onset of mitosis often leads to chromosomal instability and subsequent tumorigenesis.

The centrosome functions as the major microtubule organizing center (MTOC) of the cell and as such it determines the number, polarity, and organization of interphase and mitotic microtubules. Cytoplasmic organization, cell polarity and the equal partition of chromosomes into daughter cells at the time of cell division are all dependent on the normal ...

Centrosome-microtubule nucleation
Journal of Cell Science, 1997ABSTRACT In many cell types the formation of microtubules from tubulin subunits is initiated at defined nucleation sites at the centrosome. Thesse sites contain the conserved γ-tubulin which is in association with additional not very well characterised proteins, identified as components of a γ-tubulin ring complex from Xenopus egg ...

Aurora A, centrosome structure, and the centrosome cycle
Environmental and Molecular Mutagenesis, 2009AbstractThe centrosome, also known as the microtubule organizing center of the cell, is a membrane‐less organelle composed of a pair of barrel‐shaped centrioles surrounded by electron‐dense pericentriolar material. The centrosome progresses through the centrosome cycle in step with the cell cycle such that centrosomes are duplicated in time to serve as

Centrosome competition: A possibility?
Experimental Cell Research, 1990A recent theory on the evolution of sexuality, has hypothesized heritable variation in the functional properties of centrosomes, leading to competition for the organization of the mitotic spindle when different centrosomes enter a common cytoplasm.

Centrosomes are dynamic organelles involved in many aspects of cell function and growth. Centrosomes act as microtubule organizing centers, and provide a site for concerted regulation of cell cycle progression. While there is diversity in microtubule organizing center structure among eukaryotes, many centrosome components, such as centrin, are ...
