Summary
Extracellular environment viscosity impacts cancer cell migration. Moderate viscosity boosts migration, while high viscosity hinders it, revealing adaptive cell responses to mechanical cues.
Area of Science:
- Mechanobiology
- Cancer Biology
- Biophysics
Background:
- Cell migration is crucial for metastasis, enabling cancer cells to invade tissues and spread.
- Extracellular environment (ECE) viscosity influences cell motility, but its regulatory mechanisms are not fully understood.
Purpose of the Study:
- To investigate how ECE viscosity modulates cancer cell migration through a mechanobiological model.
- To explore the regulation of actin polymerization, retrograde flow, and adhesion dynamics by viscosity.
Main Methods:
- Development of a mechanobiological model.
- Simulation of cancer cell migration under varying ECE viscosity.
- Analysis of cytoskeletal dynamics and adhesion properties.
Main Results:
- A biphasic response of cancer cell migration to ECE viscosity was observed.
- Moderate viscosity enhanced migration by increasing actin density and adhesion.
- Excessive viscosity impeded migration due to mechanical resistance.
- A short-term migration memory phenomenon was identified, where cells retain high migration speeds after viscosity changes.
Conclusions:
- Cancer cells exhibit adaptive mechano-chemo-biological responses to ECE viscosity.
- Viscosity modulates key migration processes, influencing metastatic potential.
- Understanding these mechanisms advances knowledge of cancer cell behavior in diverse tissue environments.

01:32Cytoskeletal Coordination in Cell Migration
5.4K
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...

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

6.4K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.

6.3K
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.

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.

01:18Role of Myosin in Cell Migration
3.1K
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....
