Cell migration is the biological process in which cells move from one location to another. This is a key phenomenon in biology, involving multiple fields such as cell physiology, development, immunity, and disease. Cell migration involves numerous mechanisms, such as dynamic changes in the cytoskeleton, cell-cell interactions, and cell-matrix interactions. Technologies such as Transwell migration experiments, scratch healing experiments, and microscope tracking can be used to study cell migration, providing important information for understanding biological processes, disease development, and treatment.
