Cell culture is a technique used in biological research to grow and maintain cells outside of their natural environment. This allows researchers to study and manipulate cells in a controlled setting, enabling a wide range of studies on cell behavior, development, and disease mechanisms. Cell culture is used in various fields, including molecular biology, genetics, microbiology, and medicine, and has greatly contributed to our understanding of cellular processes and the development of new treatments and therapies. Techniques for cell culture continue to advance, allowing for more accurate and sophisticated experiments to be conducted.
