Cytoskeletal Coordination in Cell Migration

Cytoskeletal Coordination in Cell Migration

A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...

Cell Migration

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Chemotaxis and Direction of Cell Migration

Chemotaxis and Direction of Cell Migration

Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...

Role of Myosin in Cell Migration

Role of Myosin in Cell Migration

Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...

Cell Polarization by Rho Proteins

Cell Polarization by Rho Proteins

Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

Summary

This summary is machine-generated.

Cell shape influences Golgi polarization, but the Golgi complex doesn't dictate cell direction. Elongated cell geometries promote directed migration, while less constrained cells show slower movement.

Area of Science:

Cell Biology
Biophysics
Mechanobiology

Background:

Cellular polarization, involving shape changes and signaling machinery redistribution, is crucial for mammalian cell migration.
The Golgi complex's frontward polarization is hypothesized to aid directional migration, but the temporal sequence is unclear.

Purpose of the Study:

To investigate whether Golgi polarization precedes or follows directional cell migration.
To determine the role of cell geometry in Golgi polarization and migration dynamics.

Main Methods:

Cells were constrained to specific areas and shapes.
Motile behavior and Golgi apparatus spatio-temporal distribution were tracked upon release from constraints.

Main Results:

Golgi complex position is dependent on cell geometry.
Subcellular Golgi localization does not determine the cell's leading edge.
Cells in elongated geometries showed polarized lamellipodia extension and preferential migration along the long axis.
Minimally constrained cells released from larger areas exhibited retarded migration irrespective of lamellipodia protrusion.

Conclusions:

Cell geometry, not Golgi polarization, dictates the directionality of cell migration.
Golgi polarization is a consequence of cell shape rather than a driver of directional movement.
