What does "Cortical Tension" mean?
Table of Contents
Cortical tension refers to the forces generated at the outer layer of a cell, known as the cortex. This tension plays a crucial role in how cells shape themselves and move. During processes like growth and development, cells use these forces to change their form and position.
Importance in Cell Behavior
Cortical tension helps cells stick together and form connections with each other. These connections are important for creating barriers and organizing tissue. When cells generate enough tension, they can maintain strong links, which keeps the layers of cells intact and functioning properly.
How it is Measured
Measuring cortical tension can be challenging because it often requires direct access to cells and complex tools. Instead, new methods have been developed to estimate these forces by looking at images of cells. This approach allows researchers to study how tension affects cells without invasive techniques.
Role in Development
During the early stages of an organism's growth, like in embryos, cortical tension is essential for proper shape and movement of cells. Changes in this tension can influence how cells divide and interact, which is vital for forming tissues and organs. High tension helps cells to organize efficiently, while imbalances can lead to issues in development.
