Centrosome Duplication

Centrosome Duplication

The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).
To ensure that each daughter cell receives a centrosome after cell division, centrosome duplication...

Centrioles and Centrosomes

Centrioles and Centrosomes

Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.
Near the end of the prophase, also called late prophase or...

Neurulation

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Microtubules in Signaling

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Background:

Development relies on controlled cell proliferation, differentiation, and organization.
The centrosome, a key microtubule-organizing center (MTOC), is crucial for cell division, chromosome segregation, and spindle orientation.
The brain's complexity makes it vulnerable to centrosome dysfunction.

Purpose of the Study:

To discuss the consequences of centrosome dysfunction during development.
To explore the link between centrosome dysfunction and human diseases.

Main Methods:

Review of literature on centrosome function in development.
Analysis of genetic mutations associated with centrosomal genes.
Discussion of disease phenotypes linked to centrosome dysfunction.

Main Results:

Centrosome dysfunction impairs cell cycle control, proliferation, and spatial organization.
Mutations in centrosomal genes are implicated in microcephaly disorders like MCPH, SCKS, and MOPD-II.
These dysfunctions contribute to the etiology of various human developmental diseases.

Conclusions:

Centrosome integrity is vital for normal embryonic development.
Centrosome dysfunction is a significant factor in the pathogenesis of microcephalic and primordial dwarfism syndromes.
Understanding centrosome biology is key to addressing these developmental disorders.
