Insights

Hematopoietic stem cells (HSCs) can now be visualized in live animals. Recent studies allow scientists to observe HSC behavior within their natural bone marrow niches.

Area of Science:

  • Hematology
  • Stem Cell Biology
  • In Vivo Imaging

Background:

  • Visualizing hematopoietic stem cells (HSCs) in live animals has been a long-standing goal in stem cell biology.
  • Previous work by Kiel et al. (2005) enabled initial visualization of HSCs within bone cavities.

Purpose of the Study:

  • To enable real-time observation of hematopoietic stem cell (HSC) behavior within their native microenvironments.
  • To advance the understanding of HSC dynamics and interactions in vivo.

Main Methods:

  • Utilizing advanced live-animal imaging techniques.
  • Building upon established methods for HSC visualization in bone marrow.

Main Results:

  • Successful visualization of hematopoietic stem cells (HSCs) in live animal models.
  • Observation of HSC behavior and dynamics within their physiological niches.

Conclusions:

  • Recent advancements now permit direct observation of HSCs in their natural habitats.
  • These new capabilities will significantly enhance research into HSC function and regulation.

Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

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...

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.

Cell Migration

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.

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

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....

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

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...

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
