Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

3.8K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

Mechanism of Filopodia Formation

3.3K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Laminar and Turbulent Flow01:07

Laminar and Turbulent Flow

11.2K
Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Mechanisms of Membrane Domain Formation

4.2K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with...

Summary
This summary is machine-generated.

Active matter systems can become ordered by deforming their environment. This study shows how active nematic flows coupled with substrate mechanics lead to environmentally induced ordering and pattern formation.

  • Soft Matter Physics
  • Active Matter Physics
  • Biophysics

Background:

  • The interaction between active matter and its environment is key to emergent behaviors in biological and synthetic systems.
  • Understanding how active matter dynamics are influenced by environmental mechanics is crucial.

Purpose of the Study:

  • To investigate how coupling active nematic flows to substrate deformations affects system dynamics.
  • To explore the mechanism of environmentally induced ordering in active matter.

Main Methods:

  • Developed a model combining active nematohydrodynamics and substrate mechanics.
  • Simulated the behavior of active nematics on a compliant substrate.

Main Results:

  • Contractile active nematics transition from a disordered to an ordered state on a deformable substrate.
  • Environmentally induced ordering is robust and leads to distinct patterning regimes.
  • Wrinkle morphologies on the substrate reflect the active stresses within the nematic system.

Conclusions:

  • Mechanical feedback from soft environments can drive ordering in active systems.
  • This reveals a general mechanism for pattern formation in active matter.
  • The findings have implications for designing active materials and understanding biological self-organization.
