Cell Migration01:19

Cell Migration

6.5K
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.

Cell Migration

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.

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

8.4K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Canonical Wnt Signaling Pathway

10.6K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Cancer Cell Migration through Invadopodia

3.3K
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,...

Area of Science:

  • Cell Biology
  • Biochemistry

Background:

  • Cell migration is a fundamental biological process crucial for development and disease.
  • Traditional studies focused on the cell membrane and cytoskeleton.
  • Emerging evidence points to the involvement of less-explored intracellular components.

Purpose of the Study:

  • To review recent advancements in understanding cell migration.
  • To highlight the roles of underappreciated cellular components in cell movement.
  • To integrate new findings into the broader context of cell migration.

Main Methods:

  • Literature review of recent scientific publications.
  • Synthesis of findings on intermediate filaments, nucleus, extracellular vesicles, and mitochondria.
  • Analysis of their contribution to cell migration dynamics.

Main Results:

  • Intermediate filaments play dynamic roles beyond structural support.
  • The nucleus actively influences cell migration pathways.
  • Extracellular vesicles act as signaling mediators in cell movement.
  • Mitochondria are critical for energy supply and signaling during migration.

Conclusions:

  • Cell migration is orchestrated by a wider array of cellular components than previously thought.
  • Intermediate filaments, nucleus, extracellular vesicles, and mitochondria are key regulators of cell migration.
  • Future research should incorporate these components for a comprehensive understanding of cell motility.
