CELL MIGRATIONS Meaning and
Definition
-
Cell migration refers to the coordinated movement of individual cells from one location to another within an organism. This biological process is crucial for various physiological and pathological events during development, tissue repair, immune responses, and cancer progression.
In cell migration, cells undergo a series of complex and coordinated steps. First, cells detach from their original location. Then, they extend protrusions in the direction they want to move, such as lamellipodia or filopodia. These structures help the cell to adhere to the extracellular matrix or neighboring cells. Next, the cell contracts its rear end to propel itself forward, pulling its trailing edge towards the cell body. This process is called contraction and involves actin-myosin interactions. Finally, the rear of the cell disassembles, and new connections are formed at the front of the cell to allow it to keep moving forward.
Cell migration plays a fundamental role in numerous biological processes. During embryonic development, it is crucial for the formation and organization of tissues and organs. For instance, the migration of neurons enables the establishment of proper connections in the nervous system. In tissue repair, cell migration is essential for wound healing and tissue regeneration. It also plays a role in immune responses, allowing immune cells to reach sites of infection or injury. However, abnormal or uncontrolled cell migration is associated with pathological conditions like cancer metastasis, where cancer cells invade neighboring tissues and spread to distant organs.
Understanding the mechanisms underlying cell migration is a key area of research, with implications for tissue engineering, regenerative medicine, immunology, and cancer therapeutics.

Etymology of CELL MIGRATIONS
The word "cell" comes from the Latin word "cella", which means "small room" or "storeroom". It was first used to describe biological units by the English scientist Robert Hooke in the 17th century.
The term "migration" comes from the Latin word "migratio", which means "movement". It has been used in English since the late 16th century to describe the act of moving from one place to another.
When combined, "cell migration" refers to the process by which cells move or migrate from one location to another within an organism. The term is often used in the field of biology and specifically in the study of cellular behavior and development.
