Cell Migration

Cell migration is the directed movement of cells through or across tissues, an essential process for organizing organisms and maintaining tissue function. Cells migrate by sensing chemical or physical cues, extending actin-rich protrusions, attaching to the surrounding extracellular matrix through adhesion proteins, and generating contractile forces that pull the cell forward as older attachments release. In biology, cell migration supports embryonic development, wound healing, immune surveillance, and tissue repair. Studying its regulation also helps researchers understand how abnormal migration contributes to inflammation, developmental disorders, and cancer metastasis, making migration assays valuable for investigating cell behavior and potential therapies.

An Introduction to Cell Motility and Migration

0 Views •

2023

Cell motility and migration play important roles in both normal biology and in disease. On one hand, migration allows cells to generate complex tissues and organs during development, but on the other hand, the same mechanisms are used by tumor cells to move and spread in a process known as cancer metastasis. One of the primary cellular machineries that make cell movement possible is an intracellular network of myosin and actin molecules, together known as “actomyosin”, which creates a...

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. General Mechanism Generally, cellular migration begins when a cell, such as a fibroblast, responds to an...
