movement of cells or organisms from one location to another
Migration, in the context of biology, refers to the movement of cells or organisms from one location to another. For example, during hair growth, stem cells in the hair follicle migrate to different areas to facilitate the regeneration of hair. This process is crucial for tissue repair and development, and disruptions in cell migration can lead to conditions like alopecia, where hair loss occurs due to the inability of cells to properly relocate and function.
