Cell manipulation refers to the techniques used to alter or control the behavior of cells. This can involve changing their genetic material, modifying their environment, or influencing their growth and development. Scientists use these methods in various fields, including genetic engineering, stem cell research, and tissue engineering. These techniques can help in understanding diseases, developing new therapies, and creating tissues for transplantation. For example, researchers can manipulate stem cells to differentiate into specific cell types, which can then be used to repair damaged tissues. Overall, cell manipulation plays a crucial role in advancing medical science and biotechnology.
