Summary
Cells can migrate towards stiffer or softer environments, a phenomenon known as durotaxis. This review explores how cell plasticity and context influence this stiffness-guided cell migration.
Area of Science:
- Cell Biology
- Biophysics
- Mechanobiology
Background:
- Cell migration relies on adhesion, cytoskeleton dynamics, and external cues.
- Integrins mediate cell adhesion to the extracellular matrix (ECM), enabling stiffness sensing.
- Durotaxis, migration towards increasing rigidity, is well-established.
Purpose of the Study:
- To review conceptual advances in understanding cell plasticity and context-dependency in stiffness-guided migration.
- To discuss the phenomenon of negative durotaxis, where cells migrate towards lower rigidity.
Main Methods:
- Literature review of theoretical models and experimental evidence.
- Discussion of molecular mechanisms of stiffness sensing and cell migration.
Main Results:
- While migration towards increasing rigidity (durotaxis) is common, cells can also migrate towards decreasing rigidity (negative durotaxis).
- Cellular factors, including adhesion molecule balance and motor protein activity, influence migration direction.
- Recent experimental evidence supports the prediction of migration towards intermediate rigidity.
Conclusions:
- Cellular migration in response to matrix rigidity is more complex than previously thought.
- Cell plasticity and context are critical determinants of directional cell migration.
- Understanding durotaxis and negative durotaxis is key to comprehending cell behavior in various biological processes.

Mechanism of Ciliary Motion
3.7K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Types of Damping
6.4K
If the amount of damping in a system is gradually increased, the period and frequency start to become affected because damping opposes, and hence slows, the back and forth motion (the net force is smaller in both directions). If there is a very large amount of damping, the system does not even oscillate; instead, it slowly moves toward equilibrium. In brief, an overdamped system moves slowly towards equilibrium, whereas an underdamped system moves quickly to equilibrium but will oscillate about...

Induced Electric Dipoles
4.2K
A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

Cell Signaling Feedback Loops
6.3K
Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

Time-Domain Interpretation of PD Control
98
Proportional-Derivative (PD) control is a widely used control method in various engineering systems to enhance stability and performance. In a system with only proportional control, common issues include high maximum overshoot and oscillation, observed in both the error signal and its rate of change. This behavior can be divided into three distinct phases: initial overshoot, subsequent undershoot, and gradual stabilization.
