Mechanism of Filopodia Formation01:39

Mechanism of Filopodia Formation

2.4K
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...

Mechanism of Lamellipodia Formation

3.1K
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...

Cell Migration01:09

Cell Migration

16.6K
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.

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....

Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

4.8K
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...

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

2.8K
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....

  • Cell Biology
  • Developmental Biology
  • Neuroscience

Background:

  • Filopodia are dynamic cell protrusions at the leading edge of migrating cells.
  • They are proposed to function as environmental probes, sensing guidance cues.

Main Methods:

  • Literature review and evidence synthesis.
  • Analysis of studies investigating filopodia function in cell migration and tissue patterning.

Main Results:

  • Some studies suggest filopodia are dispensable for tissue guidance.
  • Neuronal and blood vessel patterning can occur without functional filopodia.
  • Evidence supporting and disputing filopodia's role is presented.

Conclusions:

  • The essential role of filopodia in guiding stereotypic neuronal and blood vessel patterns is debated.
  • Further research is needed to fully elucidate filopodia's contribution to developmental patterning.
