Cell differentiation is the process by which cells become specialized to perform specific functions within an organism. This process allows cells to develop into various cell types with distinct structures and functions, such as muscle cells, nerve cells, or skin cells. Cell differentiation is crucial for the growth, development, and maintenance of multicellular organisms. Researchers study cell differentiation to understand how cells become specialized and how this process is regulated at the molecular level. This knowledge is important for potential applications in regenerative medicine, cancer research, and the development of new therapies for various diseases.
