Introduction

The Cytoskeleton in animal cells is an intricate system that offers much more than support and maintenance. Scientists have always been fascinated by the mystery that shrouds this marvel, which plays a critical role in essential cell processes like division, movement, and morphology. Understanding this system's secrets and working principles unlocks the potential for enhanced animal cell functionality to improve treatment outcomes, organ development, and drug discovery.

The Cytoskeleton

The cytoskeleton is an intricate network of filaments and fibres that traverse throughout the cell's cytoplasm, crossing through the nucleus, and connect to the plasma membrane. This elaborate system primarily comprises three primary classes of protein filaments: microtubules, actin filaments, and intermediate filaments that work in concert to maintain cell structure and enable movement.

Microtubules

Microtubules are the thickest class of protein filaments that exist in several types of tissues. These hollow tubes are built from tubulin and play central roles in cell division, intracellular trafficking, and positioning of cellular organelles. The dynamic nature of microtubules enables the creation of a 'highway system' where motors can move cargo in various directions.

Actin Filaments

Actin filaments (also known as microfilaments) are incredibly versatile structures built from actin proteins which are critical for cell shape and size changes. These filaments are involved in cell movement, structural support and the contraction of muscle cells, and crucial intracellular transport mechanisms.

Intermediate Filaments

Intermediate filaments are stable structural filaments built from various proteins like keratin and lamin. They help anchor some organelles like the nucleus and protect cells from physical stresses.

Functions of the Cytoskeleton

The Cytoskeleton functions comprehensively to enable animal cells' diverse and essential processes. It is essential in regulating cell division, providing mechanical support, intracellular transport, cell adhesion and locomotion, among other crucial cellular functions. The following are the fundamental roles of Cytoskeleton in animal cells:

Cell shape and structural maintenance

The cytoskeleton provides animal cells with their shape and rigidity. Actin filaments determine the cells shape and size, while intermediate filaments confer strength to epithelial and muscle cells, maintaining tissue integrity.

Cell Division

The cytoskeleton system is critical in the intricate process of cell division, powering the separation of identical DNA strands and the formation of the cleavage furrow.

Intracellular transport

The cytoskeleton uses microtubules to create a shared 'highway system' for the transportation of proteins, lipids, ribosomes and other vital cargo throughout the cell's anatomy.

Cell Motility

Actin filaments and microtubules play a critical role in animal cells' movement by enabling cell crawling, flagella and cilia movement, and muscle contraction. They also help maintain the linking between the extracellular matrix and the plasma membrane.
