Summary
Cancer cells migrate collectively in vivo through rotational patterns, forming organized tracks. This invasion resembles a turbulent active fluid, offering insights into metastasis and model development.
Area of Science:
- Biophysics
- Cancer Biology
- Cellular Dynamics
Background:
- Collective cancer cell migration is often studied in vitro.
- In vivo evidence for cancer cell invasion dynamics is limited.
- Active matter physics concepts are frequently applied to cell migration.
Purpose of the Study:
- To investigate collective invasion of metastatic cancer cells in a living mouse model.
- To characterize the migration patterns and associated matrix deformations in vivo.
- To compare experimental observations with active nematic fluid models.
Main Methods:
- Intravital multiphoton microscopy in mouse deep dermis.
- Skin window technique for live imaging.
- Three-dimensional quantitative image analysis of cell movement and matrix deformation.
Main Results:
- Observed multicellular, low-cohesive migration with rotational patterns.
- Identified self-organization into antiparallel tracks with nematic order.
- Found broadly distributed compression strain bands in the extracellular matrix.
- Active nematic hydrodynamics model described key statistical features of the observed flow.
Conclusions:
- Collective cancer cell invasion in vivo exhibits characteristics of a turbulent active nematic fluid.
- The study provides a framework for understanding in vivo cancer cell migration.
- Results guide the development of more realistic in vitro and in silico models for collective cell migration.

01:19Cell Migration
4.7K
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.

01:35Cancer Cell Migration through Invadopodia
2.3K
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,...

01:32Cytoskeletal Coordination in Cell Migration
4.7K
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...

01:18Role of Myosin in Cell Migration
2.2K
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....

01:24Overview of Cell-Matrix Interactions
7.0K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

01:16Cell Motility through Blebbing
1.9K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.
