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, a phenomenon known as chemotaxis, which helps them reach areas where they are needed. During cell migration, cells undergo changes in shape and adhesion properties. They extend protrusions, such as lamellipodia and filopodia, to explore their environment and pull themselves forward. This dynamic process is crucial for maintaining tissue organization and function, as well as for the spread of certain diseases, such as cancer.
