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.

Cell-matrix's Response to Mechanical Forces

Cell-matrix's Response to Mechanical Forces

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.

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

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...

Summary

Endothelial cells

Area of Science:

Cell biology
Biomechanics
Biophysics

Background:

Endothelial cells exhibit mechanotaxis, changing migration in response to shear stress.
Cellular response to shear stress is altered on micropatterned substrates.
The role of cytoskeletal structure versus adhesion area in micropatterned endothelial mechanotaxis is unclear.

Purpose of the Study:

To investigate the mechanisms suppressing endothelial mechanotaxis on micropatterned substrates.
To determine whether cytoskeletal structure or adhesion area limits mechanosensitivity in aligned endothelial cells.

Main Methods:

Examined endothelial cells on wide (100-200 μm) micropatterned lines under shear stress.
Assessed cell morphology and migration patterns in central and edge regions of micropatterned lines.

Introduced scratch wounds perpendicular to micropatterns and observed cell migration.

Main Results:

Cells in the center of micropatterned lines showed cobblestone morphology and triphasic mechanotaxis.
Cells at the edges of micropatterned lines migrated parallel to the line axis, irrespective of flow direction.
Elongated cells on upstream edges of sparsely populated lines initially migrated parallel to the edge before aligning with shear stress.

Conclusions:

Cytoskeletal structure, not available adhesion area, is the primary determinant of endothelial mechanotaxis.
Elongated cytoskeletal organization in micropatterned endothelial cells suppresses mechanosensitivity to shear stress.
Endothelial cell migration behavior is context-dependent, influenced by substrate topography and cellular alignment.
