Summary
Cell division precisely orients the mitotic spindle for metazoan development. This spindle remains dynamic, allowing reorientation for cellular responses.
Area of Science:
- Cell Biology
- Developmental Biology
Background:
- Asymmetric cell division is crucial for metazoan development.
- The mitotic spindle's orientation dictates cell fate and tissue patterning.
- Maintaining spindle dynamics allows cells to adapt to internal and external cues.
Purpose of the Study:
- To elucidate the mechanisms underlying asymmetric mitotic spindle positioning.
- To investigate how the dynamic state of the mitotic spindle is maintained during cell division.
- To understand the cell's capacity to reorient the spindle in response to stimuli.
Main Methods:
- Utilized advanced live-cell imaging techniques.
- Employed genetic manipulation to perturb spindle-associated proteins.
- Applied biophysical methods to quantify spindle dynamics and forces.
Main Results:
- Identified key regulators controlling spindle asymmetry.
- Demonstrated that spindle components are continuously remodeled.
- Showcased the cell's ability to rapidly reorient the spindle following experimental perturbations.
Conclusions:
- Precise control of mitotic spindle positioning is essential for development.
- Spindle dynamics are actively regulated, enabling cellular responsiveness.
- These findings provide insights into fundamental cell division processes.

Microtubules
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.Microtubules are hollow tubes whose walls are made up of globular tubulin proteins. Each tubulin...
Microtubules
Microtubules are the thickest cytoskeletal filaments with a diameter of 25 nm. In prokaryotic organisms, microtubules are commonly found in locomotory appendages like cilia and flagella. In eukaryotic cells, microtubules form specialized extensions for moving fluid over the surface, like those found in cells lining the intestine.
Microtubules have two structurally similar globular protein subunits: α and β tubulins. In the cytosol, the α and β tubulins form a heterodimer. These αβ-heterodimers...

Assembly of Complex Microtubule Structures
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.
Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...
