Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

2.5K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Cell Migration01:19

Cell Migration

5.3K
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.

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

3.7K
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...

Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

4.9K
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...

Actin Polymerization and Cell Motility01:13

Actin Polymerization and Cell Motility

5.6K
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.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate....

Microtubules in Cell Motility01:24

Microtubules in Cell Motility

3.6K
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

Summary

Cell migration speed is minimally affected by fibrillar patterns, but cells struggle to deviate from tracks when pattern features match their minor axis size. This guides microfibre pattern design for cell migration control.

Area of Science:

  • Biomaterials Science
  • Cell Biology
  • Biophysics

Background:

  • Cell migration is crucial in biological processes.
  • Extracellular matrix (ECM) fibrillar morphology influences cell migration.
  • Understanding cell-matrix interactions is key for regenerative medicine and cancer research.

Purpose of the Study:

  • To investigate how different fibrillar patterns of polystyrene fibres affect cell migration dynamics.
  • To determine the relationship between cell shape, migration behavior, and micro-pattern features.
  • To identify design principles for microfibre patterns to control cell migration.

Main Methods:

  • Fabrication of straight, wavy, looped, and gridded polystyrene fibre patterns using low-voltage continuous electrospinning (fibre diameter ~3 μm).
  • Analysis of cellular migration dynamics of MDA-MB-231 breast cancer cells on these patterns.
  • Quantitative assessment of cell shape, migration trajectories, and average step speed.

Main Results:

  • Cells dynamically adjusted their shapes and migration paths in response to various fibrillar patterns.
  • Average cell step speed showed minimal dependence on the global fibre pattern.
  • Cellular ability to deviate from fibre tracks was limited when pattern features approached the cell body's minor axis dimensions.

Conclusions:

  • The global pattern of fibrillar structures has a limited impact on average cell migration speed.
  • The cell body's minor axis dimension is a critical factor limiting deviation from fibre tracks.
  • Microfibre pattern design should consider the cell body's minor axis for effective control of cell migration.
