Cell migration is the process by which cells move from one location to another within an organism. This movement is essential for various biological functions, including embryonic development, wound healing, and the immune response. Cells can migrate in response to chemical signals in their environment, a phenomenon known as chemotaxis. During cell migration, cells undergo changes in shape and adhesion properties. They extend protrusions, such as lamellipodia and filopodia, to explore their surroundings and pull themselves forward. This dynamic process is crucial for maintaining tissue organization and repairing damaged areas in the body.
