Cell mobility, also known as cell migration, is a term used to describe a cell's ability to move from one location to another. It is a fundamental cellular process that has a major role in development and tissue organization, immunity, and wound healing.

Cell mobility is essential for normal embryonic and tissue development, as well as for immune responses, inflammation, and wound healing. In a developing embryo, cell motility is necessary for cell migration, and for the arrangement of cells into proper tissue structures. As an example, during the early stages of development and differentiation, epithelial cells must move away from the ectoderm and spread across the surface of the embryo to form the correct structure. This migration is also required during wound healing, where it stimulates tissue repair and healing.

Cell mobility is also involved in the immune response. Immune cells, such as leukocytes, must be able to migrate across the body in order to reach areas of infection or injury. This is also true for cells that play an important role in inflammation, such as macrophages and mast cells.

Cell mobility is controlled by a number of different forces, both intrinsic and extrinsic. Intrinsic forces, or those that come from inside the cell, include changes in actin cytoskeletal structure and the generation of cationic gradients. Extrinsic forces, or those that come from outside of the cell, include gradients of chemoattractants, cell-cell interactions, and physical forces such as flow.

Cell mobility is necessary for the development and functioning of organisms. It plays an important role in shaping the body during development, and in immune and inflammatory responses throughout the body. Studying cell mobility is important for understanding many different biological processes.
