Cell Migration01:09

Cell Migration

17.1K
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.

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...

Activation of Integrins01:15

Activation of Integrins

3.5K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

2.4K
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....

Gastrulation01:56

Gastrulation

58.0K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Area of Science:

  • Developmental Biology
  • Cell Biology
  • Cancer Biology

Background:

  • The neural crest is a crucial embryonic structure.
  • Melanoblasts, the precursors to melanocytes, originate from trunk neural crest cells.
  • Defects in melanoblast migration lead to pigmentation issues and are relevant to metastatic skin cancer.

Purpose of the Study:

  • To investigate the role of integrin-based adhesion in melanocyte migration.
  • To establish a powerful ex vivo method for studying melanoblast migration.

Main Methods:

  • Utilized skin explants from embryos.
  • Employed genetically encoded markers for melanocytes.
  • Applied high-resolution live imaging techniques.

Main Results:

  • Demonstrated the utility of skin explants and live imaging for analyzing melanoblast migration.
  • Provided evidence for the critical role of integrin-based adhesion in this process.

Conclusions:

  • The described ex vivo approach is effective for studying melanoblast migration.
  • Integrin-mediated adhesion is essential for proper melanocyte development and migration.
